中国石油网消息：6月24日，从川庆钻探公司获悉，中国石油页岩气“211工程”在泸201井区取得阶段性成效，完钻井速度较同区域平均水平提高25%以上，钻井成本同比下降，标志着我国深层页岩气钻井提速实现重大突破。

China Oil News: On June 24th, a reporter from Sichuan Qingzhen Drilling Company informed that the "211 Project" of China National Petroleum Corporation has achieved phased results in the Lu 201 well area. The completion speed of the wells is over 25% higher than the average level in the same area, and the drilling cost has decreased compared to the previous period. This indicates that our country has made a major breakthrough in accelerating deep shale gas drilling.

当前，以页岩气为代表的非常规油气是我国“稳油增气”最现实的接替资源。与中浅层相比，深层页岩气埋藏更深、地应力更复杂，导致钻井和压裂成本成倍攀升，高昂的投入已成为制约其实现规模效益开发的主要瓶颈。

Currently, unconventional oil and gas resources such as shale gas represent the most practical alternative resources for maintaining and increasing oil and gas production in China. Compared with shallow and medium-depth layers, deep shale gas is buried deeper and has more complex geological stresses, which leads to a significant increase in drilling and fracturing costs. The high investment has become the main bottleneck restricting the realization of large-scale and efficient development of this resource.

泸州深层页岩气被誉为川南页岩气“最难啃的硬骨头”。数据显示，泸201H6和H7平台平均埋深超4700米，地下常规井温达160摄氏度。基于此，中国石油围绕“单井EUR（最终可采储量）提高20%、单位EUR成本降低10%、钻井和压裂时效提高10%”目标，在泸201井区部署实施旨在提速、降本、增效的“211工程”。作为承建单位，川庆钻探携手西南油气田公司，闯出一条国内深层页岩气钻井提速的新路径。

The deep shale gas in Luzhou is regarded as the "most difficult-to-crack bone" among the shale gas resources in southern Sichuan. According to the data, the average burial depth of the L201H6 and H7 platforms exceeds 4,700 meters, and the underground conventional well temperature reaches 160 degrees Celsius. Based on this, China National Petroleum Corporation has set the goal of "increasing the final recoverable reserves of a single well by 20%, reducing the cost of each final recoverable unit by 10%, and increasing the drilling and fracturing efficiency by 10%" and has deployed and implemented the "211 Project" in the L201 well area, aiming to accelerate drilling speed, reduce costs, and increase efficiency. As the construction unit, Chuanqing Drilling Company has joined hands with the Southwest Oil and Gas Field Company to blaze a new path for speeding up deep shale gas drilling in China.

突破源于思想解放。“211工程”打破传统甲乙方专业壁垒，依托全成本经营总包改革，构建以EUR为核心的一体化管理模式。“以前产量由甲方负责，现在实行EUR联责考核，达标分成、不达标扣减，效益建产关系到双方切身利益。”川庆钻探副总工程师干建华说。同时，川庆钻探向钻井队下放物资采购等12项经营自主权，真正实现“现场问题现场定，井队事务井队管”。

Breakthroughs stem from ideological liberation. The "211 Project" broke through the traditional professional barriers between the contractor and the client, relying on the total cost management and general contracting reform, to establish an integrated management model centered on EUR. "Previously, the output was the responsibility of the client. Now, there is a joint responsibility assessment based on EUR, with a share for meeting the standards and deductions for not meeting them. The efficiency and production benefits are closely related to the vital interests of both parties," said Gan Jianhua, the deputy chief engineer of Chuanqing Drilling. At the same time, Chuanqing Drilling has delegated 12 items of business autonomy, such as material procurement, to the drilling teams, truly achieving "on-site decisions on-site, and on-site management of on-site affairs".

突破源于机制盘活。川庆钻探实行“盈利、持平、减亏”三档差异化考核，超额盈利部分按照20%的比例拨付给井队自主分配。政策红利下，一线井队主动深挖降本潜力：员工利用施工间隙自主清掏泥浆罐，省去外包费用；全员自建供水管线，仅此一项较外协施工节约成本数十万元；各队伍按需精简用工、优化班组配置，形成“比学赶超”氛围。

The breakthrough stems from the activation of the mechanism. Chuanqing Drilling implements a three-level differentiated assessment system of "profit, parity, and reduction of losses", and the excess profits are allocated to the well teams for autonomous distribution at a rate of 20%. Under the policy benefits, the front-line well teams actively explored ways to reduce costs: employees independently cleaned the mud tanks during breaks, eliminating the need for outsourcing; all staff built their own water supply pipelines, saving tens of thousands of yuan compared to external contracting; each team streamlined the workforce as needed and optimized the configuration of work teams, creating a "competition, learning, and surpassing" atmosphere.

突破源于技术革新。“211工程”采用恒扭矩模式钻进，配套优化钻具组合与钻头选型，加装减震工具抑制钻柱振动，确保钻头稳定地吃入地层，二开、三开机械钻速较区块最优水平分别提升46.2%、84.6%。

The breakthrough stems from technological innovation. The "211 Project" adopted a constant torque drilling mode, optimized the drilling tool combination and selected the drill bit, and installed shock absorption tools to suppress the vibration of the drill string, ensuring that the drill bit could stably penetrate the formation. The mechanical drilling rates for the second and third openings were respectively increased by 46.2% and 84.6% compared to the optimal levels of the block.

突破源于数智赋能。在泸201井区，钻井平台已建成钻完井现场数智化指挥中心，卡钻预警准确率达95%，钻完井故障时效同比下降29%。通过智能轨迹优化，H6、H7平台分别减少定向段300米、500米，累计缩短钻井周期4.8天；H6平台更以52天刷新川渝地区单机单队最快万米进尺纪录。

The breakthrough stems from digital and intelligent empowerment. In the Lushan 201 well area, the drilling platform has established a digital and intelligent command center for the drilling and completion site. The accuracy rate of stuck pipe warning has reached 95%, and the timeliness of drilling and completion failures has decreased by 29%. Through intelligent trajectory optimization, the H6 and H7 platforms have respectively reduced the directional section by 300 meters and 500 meters, and the cumulative drilling cycle has been shortened by 4.8 days; the H6 platform even set a new record for the fastest 10,000-meter drilling rate per single machine and single team in the Sichuan-Chongqing region, with a time of 52 days.
