中国石油网消息：4月20日，吉林油田大老爷府作业区首轮5口油井压裂施工圆满收官，打响全年生产任务“头炮”。其中，已停产6年的老2-24井经过连续数日的技术攻坚，成功“满血复活”，为老井挖潜增效树立了典范。

China Oil News: On April 20th, the first round of fracturing operations for 5 oil wells in the Dalaguofu Operating Area of Jilin Oilfield was successfully completed, kicking off the "first shot" of the annual production tasks. Among them, the old No. 2-24 well, which had been out of production for 6 years, successfully "revived" after continuous technical efforts over several days, setting a model for tapping the potential and increasing efficiency of old wells.

初春生产，老井难题凸显。吉林油田长期生产油井存在地层返排残留淤积、井壁结垢严重、井筒清洁度差等瓶颈。其中，老2-24井距上次检泵已时隔6年，尾管结垢厚达5毫米，套管缩径，扫钻作业举步维艰，钻至1180米后，日进尺仅30米，施工一度停滞。

In the early spring, problems with old wells emerged. The oil wells in Jilin Oilfield that have been in continuous production have encountered several bottlenecks, such as residual debris from formation backflow, severe well wall scaling, and poor cleanliness of the wellbore. Among them, the old No. 2-24 well has not been inspected for pumping since the last time six years ago. The scale on the tail pipe is as thick as 5 millimeters, the casing has shrunk, and the drilling and cleaning operations have been extremely difficult. After drilling to 1180 meters, the daily progress was only 30 meters, and the construction was temporarily halted.

面对专业性难题，吉林油田技术团队扎根一线，作业队伍迎难而上。历时10天、3次更换钻头，一寸寸攻坚完成了扫钻压准。技术人员现场取样化验，精准分析钙镁离子含量，采用底部加化学防垢管完井方案，从根源上消除堵塞，让高龄井重焕生机。

In the face of professional challenges, the technical team of Jilin Oilfield worked closely at the front line, and the operation teams bravely took on the difficulties. After 10 days and three changes of drill bits, inch by inch, they successfully completed the drilling pressure relief operation. The technicians took samples on-site for testing, precisely analyzed the content of calcium and magnesium ions, and adopted a bottom chemical anti-scaling pipe completion plan to eliminate the blockage at the root cause, thus reviving the aging wells.

施工中，吉林油田技术团队“一井一策、一段一优”精细落地。采用“清水+胍胶+石英砂”低成本高效工艺，创新“前置液+增油剂”组合疏通炮眼；运用“限流射孔+精准暂堵”实现靶向改造，优化压裂液与支撑剂，提升导流能力。同时，工艺部门技术人员还建立了“技术+现场”一体化联动机制，24小时值守，全流程把控关键指标，快速处置突发工况，从而实现了一次性施工成功。

During the construction process, the technical team of Jilin Oilfield implemented the strategy of "one well, one plan; one section, one optimization" in a meticulous manner. They adopted the low-cost and efficient process of "clear water + guan gum + quartz sand", innovatively using "preliminary fluid + oil enhancer" to clear the blast holes; they applied "flow-limiting perforation + precise temporary blocking" to achieve targeted modification, optimized the fracturing fluid and support materials, and enhanced the flow capacity. At the same time, the technical personnel of the process department also established an integrated "technology + site" linkage mechanism, providing 24-hour duty, controlling key indicators throughout the process, and quickly handling unexpected situations, thus achieving the success of the one-time construction.

“我们坚持地质选层、工艺攻坚、生产统筹等多专业协同发力，才实现了首轮压裂的提前完成。”吉林油田生产一线技术人员冯艳军说。下一步，技术团队将持续聚焦井筒治理、压裂提质，深耕老井挖潜，以更高标准推进后续作业，以实现老油田提质增效。

"We achieved the early completion of the first round of fracturing through the collaborative efforts of multiple specialties, including geological layer selection, technological breakthroughs, and production coordination," said Feng Yanjun, a technical staff member from the production front line of Jilin Oilfield. In the next step, the technical team will continue to focus on wellbore treatment and fracturing improvement, deepen the exploitation of old wells, and promote subsequent operations with higher standards, in order to achieve efficiency improvement and cost reduction in the old oilfield.
