8月29日12时，廊坊采油作业区工作群弹出一条滚烫的喜讯：“安69-51x井成功解卡，已恢复正常生产，后续加密巡检！”盯着屏幕，巡检班员工杜尚彬紧绷了两天两夜的肩膀终于松了下来，连日的疲惫顺着后颈的汗意悄悄散去。

At 12:00 on August 29th, a scorching piece of good news popped up in the work group of Langfang Oil Production Area: "Well An69-51x has successfully been freed from the stuck condition and has resumed normal production. Further intensified inspections will be carried out!" Looking at the screen, Du Shangbin, an employee of the inspection team, whose shoulders had been tense for two days and two nights, finally relaxed. The fatigue that had accumulated over the days gradually dissipated along with the sweat on the nape of his neck.

时间倒回8月26日9时。杜尚彬一条紧急汇报打破了技术群的平静：安69-51x井光杆从上死点下行至距下死点1.5米处突然遇阻——井卡了。

The time was 9 o'clock on August 26th. A sudden report from Du Shangbin disrupted the calmness of the technical team: The drill pipe of well AN69-51x suddenly got stuck when it descended from the upper dead point to a position 1.5 meters below the lower dead point. The well had been clogged.

作业监督李海军攥着手机转身就往副经理孙建伟办公室跑，两人当场对着井史台账研讨起来。

Li Haijun, the supervisor of the homework, held his phone and turned to run towards the office of Deputy Manager Sun Jianwei. The two of them immediately started discussing the well history records together.

“这口井上月底刚检泵开井，才平稳十几天又卡了，不能盲目动手，得先‘把脉问诊’，找准病根再开方。”孙建伟指尖点着井史记录，眉头拧成了结。

"At the end of last month, this well was just pumped and put into operation. It had been running smoothly for just a few days before it got stuck again. We can't act rashly. We need to first 'examine the condition' and identify the root cause before we can prescribe a solution." Sun Jianwei pointed at the well history records with his fingers, and his eyebrows knitted together in confusion.

“上次卡泵是金属异物卡了活塞，泵筒里还残留灰浆。这口井冲次很低，每分钟才1.8次，完井时装了沉砂管和防腐保护器，按常理不该卡——大概率是近期地层出灰浆加重了。”李海军翻出近三个月生产数据，一页页比对，抽丝剥茧般把地下的“病因”揪了出来。

"The last time the pump got stuck, it was because a metal foreign object had jammed the piston, and there was still some slurry left in the pump barrel. This well has a very low pumping frequency, only 1.8 times per minute. During the well completion process, a sand trap and anti-corrosion protector were installed. According to normal circumstances, it shouldn't have stuck - most likely it's because the formation produced more slurry recently." Li Haijun pulled out the production data from the past three months and compared page by page. He pieced together the "causes" underground like unraveling a skein of threads.

“就按这个思路干！明天协调两辆罐车接力洗井，先起出光杆和抽油杆短节，大排量把淤积物冲干净，这口井咱们一定得解开！”李海军把安全帽往桌上一放，语气不容动摇。

"Just follow this plan! Tomorrow, we'll coordinate two tanker trucks to work in tandem to clean the well. First, we'll remove the polished rods and the short sections of the sucker rods. Then, with high flow rates, we'll flush out the accumulated substances. We must get this well unclogged!" Li Haijun placed his safety helmet on the table and his tone was unyielding.

8月27日16时，特意换了班的杜尚彬早早就守在井场。天边乌云越积越厚，一场急雨眼看就要砸下来。作业车辆就位，吊车稳稳起吊光杆，大排量洗井连续推进2小时，用水35立方米，出口返液不断带出浑浊灰浆，直到进出口水质完全一致才停泵。

At 4:00 PM on August 27th, Du Shangbin, who had changed shifts, arrived at the well site early. Dark clouds were gathering in the sky, and a heavy rain was about to fall. The operation vehicles were in position, the crane lifted the drill pipe steadily, and the large-scale well flushing operation continued for 2 hours, using 35 cubic meters of water. The turbid slurry kept flowing back from the outlet, until the water quality at the inlet and outlet was completely the same, at which point the pump was stopped.

可再次下入抽油杆短节试抽时，光杆下行依然遇阻，卡点还上移了——第一轮解卡，宣告失败。

When attempting to test the pumping again by lowering the sucker rod joint, the polished rod still encountered resistance as it descended, and the jamming point had moved upward. - The first round of unjamming attempt ended in failure.

杜尚彬站在泥泞的井场上，死死盯着缓缓运转的抽油机。雨水混着热汗顺着安全帽檐往下淌，砸在脚边的泥水里，心里像压了块石头。

Du Shangbin stood in the muddy oil well site, staring intently at the slowly rotating oil pump. Rainwater mixed with sweat trickled down the brim of his safety helmet and splashed onto the muddy water at his feet, weighing heavily on his heart.

“明天直接把活塞完全提出泵筒，重新调整洗井参数接着干，我就不信啃不下这块硬骨头！”电话那头，孙建伟的声音隔着听筒都透出一股越挫越勇的韧劲。

"Tomorrow, I'll simply pull the piston completely out of the pump cylinder, adjust the well flushing parameters again, and then continue working. I don't believe I can't crack this tough nut!" On the other end of the phone, Sun Jianwei's voice, even through the receiver, exuded an indomitable spirit of growing stronger in the face of adversity.

8月29日9时，最后一根抽油杆稳稳起出，藏在泵筒里的活塞终于完全提出工作筒。“你看返液！比上次干净太多，这次肯定把淤积物彻底冲通了！”杜尚彬紧锁了两天的眉头，这一刻终于舒展开来。

At 9 o'clock on August 29th, the last oil pumping rod was steadily lifted out. The piston hidden inside the pump cylinder was finally completely withdrawn from the working cylinder. "Look at the return fluid! It's much cleaner than last time. This time, the accumulated substances must have been completely flushed away!" Du Shangbin, whose brows had been tightly knitted for two days, finally relaxed at this moment.

后续作业人员挂好抽油机负荷，试抽憋压至3兆帕，稳压30分钟压力丝毫不降，抽憋测试完全合格，现场随即正常启抽。看着抽油机重新稳稳上下摆动，杜尚彬抬头望向雨后天晴的湛蓝天空，脸上露出连日来第一个踏实的笑容。

The subsequent operators adjusted the load of the pumping unit, conducted a test pumping with a pressure buildup to 3 megapascals, and maintained the pressure for 30 minutes. The pressure did not drop at all during this period, and the pumping test was completely qualified. Immediately after that, the pumping operation was resumed normally. Watching the pumping unit swing steadily up and down again, Du Shangbin looked up at the clear blue sky after the rain, and a relieved smile appeared on his face for the first time in several days.

“多亏所有人咬着牙没放弃，这下直接避免了动管柱重复作业，省下不少成本！”杜尚彬拧开一瓶矿泉水递过去。李海军抹了一把脸上混着油污的汗水，爽朗地笑了：“地下的情况再复杂，咱们石油人也得把它摸得明明白白——再难的卡，也得给它解开。”

"Thanks to everyone holding on and not giving up, this time we avoided the repetitive operation of running the pipe and saved a lot of costs!" Du Shangbin unscrewed a bottle of mineral water and handed it over. Li Haijun wiped the sweaty mixture of oil and dirt off his face and laughed heartily: "No matter how complicated the situation underground is, we oil workers must understand it clearly - no matter how difficult the stuck point is, we must solve it."

风掠过井场，抽油机稳稳地上下摆动，把源源不断的地下能源顺着管线输向远方。

The wind swept across the oil field, and the pumping machine moved up and down steadily, transporting the continuous underground energy along the pipeline to distant places.
