10月6日，在云南省昆明市安宁市的安2-A井井场，渤海钻探第二固井公司水泥车轰鸣声渐息，技术套管固井碰压结束，压力15兆帕，稳压10分钟不降。截至目前，这个公司6年来在西南市场累计固井施工已突破1000井次。

On October 6th, at the well site of Well An2-A in Anning City, Kunming City, Yunnan Province, the roar of the cement truck from Bohai Drilling's Second Cementing Company gradually subsided. The cementing operation of the technical casing was completed with a pressure of 15 megapascals, and the pressure remained stable for 10 minutes without dropping. As of now, this company has carried out a total of over 1,000 cementing operations in the southwestern market over the past six years.

“千井次”，不只是一个数字。比“千井次”更有分量的是业务“成分”的改变。截至目前，这个公司西南地区新能源业务占比由去年的3.3%跃升至如今的43.18%。贵州煤层气、昆明压缩空气储能、康定地热等新能源项目陆续落地。此外，今年8月，这个公司南方项目部单月盈利更是创6年来新高。新能源业务占比越来越高。

"Qian Jingci" is not just a number. What carries more weight is the change in the composition of the business. As of now, the proportion of the company's new energy business in the southwestern region has soared from 3.3% last year to 43.18% this year. New energy projects such as coalbed methane in Guizhou, compressed air energy storage in Kunming, and geothermal energy in Kangding have been successively implemented. Moreover, in August this year, the profit of the company's southern project department in a single month reached a new high in the past six years. The proportion of new energy business is increasing.

拿下首口井，西南站稳脚

Take control of the first well, and firmly establish a foothold in the southwest.

9月23日，这个公司南方项目部固井小队仅耗时4小时，便高质量完成阳101H52-3井244.5毫米技套固井施工任务，施工到井率、设计符合率均达100%。

On September 23rd, the cementing team of the southern project department of this company completed the 244.5-millimeter technical casing cementing operation for Well Yang 101H52-3 within just 4 hours. The well completion rate and design compliance rate both reached 100%.

如今的高效施工，离不开啃下这个区块第一口井的艰难起步。2021年，泸203H153-8井导管固井开工，是这个公司进入四川后施工的第一口井。当时，整个项目部仅有12个人、2台水泥车，新入驻的基地还在装修。

Today's efficient construction would not have been possible without the arduous initial stage of drilling the first well in this area. In 2021, the casing cementing operation for the Lu 203H153-8 well began. This was the first well constructed by the company after entering Sichuan. At that time, the entire project team consisted of only 12 people and 2 cement trucks. The newly established base was still under renovation.

那是川南最多雨、闷热的季节。井场在泸县乡间的山坡上，场地逼仄，设备怎么摆，要反复丈量。比天气和场地更硬的难题在地层，泸州区块深层页岩气目的层埋深近4000米，茅口组漏失多发、浅层气活跃，是块难啃的骨头。

That was the rainiest and hottest season in southern Sichuan. The well site was on a hillside in the countryside of Luzhou County. The area was cramped and the equipment had to be repeatedly measured to determine its placement. The more difficult problems lay in the geological strata. The target layer of deep shale gas in the Luzhou block was buried nearly 4,000 meters deep. The Maokou Formation had many leakage incidents and abundant shallow gas, making it a tough nut to crack.

“第一口井干得质量怎么样，直接关系着有没有第二口井。”这个公司南方项目部经理李强说。没有任何经验可循，李强带队主动拜访10余家兄弟单位的固井项目部，一趟趟请教页岩气井施工经验。项目骨干张呈星打趣说，李强手机里的导航路径图，密得像一张罩住西南三省的蜘蛛网。

"The quality of the first well drilling directly determines whether there will be a second well. " said Li Qiang, the project manager of the southern branch of this company. With no prior experience to follow, Li Qiang led his team to visit the cementing project departments of over 10 sister units, traveling back and forth to seek knowledge about shale gas well construction. Project key member Zhang Chengxing quipped that the navigation route map in Li Qiang's phone was so dense, it resembled a spider web covering the three southwestern provinces.

取回来的经，还要自己一遍遍地消化。施工前，这个公司开展了3次桌面推演，把可能遇到的复杂情况摆到桌面上；化验室里摞起一摞摞水泥浆配方调整报告，针对复杂井况逐条“磨”出应对措施。最终，泸203H153-8井导管固井顺利完成。

The retrieved drilling instructions need to be thoroughly digested by oneself. Before the construction, this company conducted three tabletop simulations, presenting the possible complex situations on the table; in the laboratory, stacks of cement slurry formula adjustment reports were piled up, and for each complex well condition, corresponding countermeasures were "worked out" one by one. Eventually, the casing cementing of the Lu 203H153-8 well was successfully completed.

此后一口井接一口井。这个项目部固井质量合格率始终保持100%，累计收到甲方表扬信、感谢信50余封，足203H2-1井139.7毫米套管气层固井更是一举打破集团公司页岩气井固井井深最深纪录。这支队伍，在西南市场站稳了脚跟。

From then on, one well after another was drilled. The cementing quality rate of this project department remained at 100% throughout. A total of over 50 letters of praise and gratitude from the client were received. The 203H2-1 well, which used a 139.7-millimeter casing for gas layer cementing, broke the record for the deepest cementing depth of shale gas wells of the group company. This team has firmly established a foothold in the southwestern market.

跳出舒适区，市场更广大

Step out of your comfort zone and the market will be much broader.

进入2026年，新的挑战出现在渤钻第二固井公司面前，传统能源市场收紧，新能源市场业务几乎为零，转型突破迫在眉睫。

Entering 2026, new challenges emerged for Bozhuan Second Cementing Company. The traditional energy market tightened, while the business in the new energy sector was almost non-existent. A transformation breakthrough was urgently needed.

“第一脚”最难踢。这个公司把西南区域新能源市场的相关公司一家家摸清，六省一市逐一跑遍。贵州的一家煤层气企业在700多公里外的盘州市。李强没有贸然上门，而是和副总工程师付家文、项目部技术队长陈大勇一起组建了市场攻关小队，依托当地油井水泥承包商，获取盘州煤层气施工第一手资料，连续3天研讨，全面分析建设方的井型、地层条件及既往施工情况，把服务模式、价格、结算周期在出发前就算出头绪，设备、物资清单一遍遍地核对。在谈判时，仅用一小时便谈妥了煤层气与瓦斯治理固井合同的相关条款。

"The first kick" is the most challenging. This company thoroughly investigated all the relevant companies in the new energy market of the southwestern region, visiting each province and city one by one. A coalbed methane enterprise in Guizhou was located over 700 kilometers away in Panzhou City. Li Qiang did not rush to visit directly. Instead, he, together with the deputy chief engineer Fu Jiawen and the technical team leader Chen Dayong of the project department, formed a market breakthrough team. They relied on the local oil well cement contractor to obtain the first-hand information on the construction of coalbed methane in Panzhou. They held discussions for three consecutive days, comprehensively analyzing the well type, geological conditions and previous construction situations of the construction party. They worked out the service model, price, settlement cycle in advance before departure, and repeatedly checked the equipment and material lists. During the negotiation, they reached an agreement on the relevant terms of the coalbed methane and gas control cementing contract in just one hour.

“说实话，出发前那一晚我几乎没合眼。”张呈星回忆道，“传统市场干了这么多年，突然要敲陌生客户的门，心里真没底。可李经理说了一句话——‘咱们不是去求人，是去帮人解决问题。’这句话把大家点醒了。”贵州山区的上井路比川渝更险，井场距离公路有3.8公里的乡村路，四桥工程车却要一个半小时才能开进去。

"To be honest, the night before we set out, I hardly slept a wink," Zhang Chengxing recalled. "The traditional market had been in operation for so many years. Suddenly, we had to approach unfamiliar clients. We really didn't know what to expect. But Manager Li said something - 'We are not asking for favors, but helping people solve problems.' This sentence woke everyone up." The road in the mountainous area of Guizhou is even more dangerous than that in Sichuan and Chongqing. The well site is 3.8 kilometers away from the road in a rural area, and it takes a 4-bridge engineering vehicle one and a half hours to get there.

这样的路，他们一条条蹚了过来。4口井干完，建设方牵线引来了第二家煤层气客户。

They braved one road after another to make it through. After completing the construction of four wells, the construction party facilitated the introduction of a second coalbed methane customer.

中国地质调查局长沙中心两口关键参数井招标中，渤钻第二固井公司以技术标排名第一的成绩中标。中标的底气，是拥有国内唯一API Q1、Q2双体系认证和CNAS实验室认可资质。随着市场一步步走出去，云南、四川、重庆等6省市越来越多的企业陆续成为这个公司的稳定客户与战略合作伙伴。

The bidding for two key parameter wells of the Changsha Center of the China Geological Survey has been concluded. Bohua Drilling's Second Cementing Company won the bid with the highest score in the technical category. The reason for its success is that it holds the only dual API Q1 and Q2 certification and CNAS laboratory accreditation qualifications in China. As the market expands step by step, more and more enterprises from six provinces including Yunnan, Sichuan and Chongqing have successively become stable clients and strategic partners of this company.

“从‘没人认识’到‘有人主动找上门’，这中间的距离，是几百个日夜、上万公里路跑出来的。”李强感慨道，“但最难的还不是跑路，是心里那道坎——敢不敢从舒适区跳出去。跳出去了，市场就大了。”

"From 'no one knew' to 'someone came to us actively', the distance covered during this process was hundreds of days and thousands of kilometers of running. " Li Qiang said with emotion. "But the hardest part wasn't the running itself; it was the psychological barrier - the courage to step out of the comfort zone. Once you do that, the market expands."

超级“充电宝”要管30年

The super "power bank" is expected to last for 30 years.

最大的硬仗在云南——今年1月，全国首个高原压缩空气储能示范项目开工，人称高原“超级充电宝”，要让其30年不漏气，固井密封是要把住的第一道关口。

The toughest challenge lies in Yunnan Province. In January this year, the country's first high-altitude compressed air energy storage demonstration project was officially launched. It is called the "super battery" of the plateau. To ensure it remains leak-free for 30 years, the well cementing and sealing process is the first critical step that must be strictly controlled.

首口井导管钻进即遇失返性漏失，水泥浆有进无出。空气储能项目负责人何冠羲带队改用“锯末搭桥”法：以纤维在裂缝中卡住、缠绕、堆积，先搭骨架，再用混凝土填实环空，最后用水泥浆井口吊灌封死缝隙。10井次导管施工全部一次成功。

The first well's casing drilling immediately encountered a non-recoverable leakage, with the cement slurry flowing in but not out. The project leader of the air storage project, He Guanshi, led the team to adopt the "sawdust bridge construction" method: using fibers to block, wrap and pile up in the cracks, first building a framework, then filling the annulus with concrete, and finally using the wellhead to pump cement slurry to seal the gaps. All 10 well casing constructions were successful in one go.

漏失刚稳住，新的问题又冒出来。表层固井声幅检测发现，含盐层一二界面胶结合格率不到90%。虽然合同只要求达到70%，可储能井的水泥环要管住地下库舱30年，这个标准自然是越高越好。那段时间，张呈星几乎住在了化验室里。他带着团队一遍遍地调配方，有时候刚躺下，脑子里突然闪过一个思路，又爬起来往实验室跑。

The problem was just stabilized, but a new one emerged. The surface cementing amplitude detection revealed that the bond rate of the interface between the first and second salt layers was less than 90%. Although the contract only required a rate of 70%, the cement ring of the storage well needed to seal the underground reservoir for 30 years. This standard naturally had to be as high as possible. During that period, Zhang Chengxing almost lived in the laboratory. He led his team to repeatedly adjust the formula. Sometimes, just as he lay down, a thought suddenly flashed through his mind, and he would get up and rush to the laboratory.

面对高原地下浅层温度低，水泥凝固后硬化时间长，含盐地层又干扰凝固，这个公司紧急优化配方，提高抗干扰和抗压强度。井眼尺寸大，钻井液顶替不干净，就调低水泥浆初始稠度，改用塞流顶替。最终，第二口井表层固井合格率升至94%。一项项磨下来，一套早强抗盐水泥浆体系就此成形，后续60井次固井，合格率100%，为地下库舱密封提供了成熟的固井方案。

Due to the low temperature in the shallow underground layers of the plateau, the cement takes a long time to harden after setting, and the salt-bearing strata interfere with the solidification process. This company urgently optimized the formula to enhance the anti-interference and compressive strength. With a large wellbore size and incomplete replacement of the drilling fluid, the initial consistency of the cement slurry was reduced, and the plug-flow replacement method was adopted. Eventually, the qualified rate of surface cementing for the second well rose to 94%. Through continuous refinement, a set of early-setting and salt-resistant cement slurry system was formed. For the subsequent 60 cementing operations, the qualified rate was 100%, providing a mature cementing solution for the sealing of underground storage tanks.

“合同要求70%，我们做到了100%。”张呈星说这话时语气平静，眼里有光，“这不是我们非要跟自己较劲，是这座‘充电宝’要管30年，马虎不得。”

"The contract required 70%, but we achieved 100%." Zhang Chengxing said this with a calm tone, his eyes shining. "This is not because we have to push ourselves to the limit. This 'power bank' needs to last for 30 years, and we can't afford to be careless."

夜色漫上井场，水泥车轰鸣声再次响起。6年千井次，渤钻二固把技术优势转化为市场胜势，创造了5项全国固井纪录、10余项区域纪录。西南群山间，这支队伍让更多新能源固井项目相继落地成景。

The night fell over the well site, and the roar of the cement trucks resounded again. Over the past six years, 6,000 times, Bohua No.2 Solidification Team has transformed its technical advantages into market dominance, setting five national solidification records and over ten regional records. In the mountains of the southwest region, this team has enabled more new energy solidification projects to be successfully implemented and come into being.
