中国石油网消息：8月31日，从辽河油田获悉，该油田采油工艺研究院自主研发的携排砂泄油深抽举升技术，有效攻克了油田中后期开发过程中普遍存在的偏磨油井泄油技术难题。该技术自5月进入规模化推广阶段以来，已成功应用205井次。

China Oil News: On August 31st, the Oil Production Technology Research Institute of Liaohe Oilfield announced that the deep pumping and lifting technology for carrying and discharging sand and oil, independently developed by the institute, has effectively solved the common problem of oil well drainage in the later stage of oilfield development. Since May, when this technology entered the stage of large-scale promotion, it has been successfully applied in 205 wells.

随着辽河油田开发进入中后期，井筒偏磨的油井数量逐年增多，导致管内井液难以顺利排出。针对这一行业共性难题，辽河油田采油工艺研究院技术团队，对成熟的长柱塞防砂泵结构进行全方位迭代优化，创新研发并加装了撞击式泄油器，依托投杆重力撞击原理，通过井口精准投棒即可稳定开启井下泄油通道，实现了起管柱作业时油管内井液快速释放，高效完成作业工序，彻底规避了杆管偏磨对泄油作业的干扰。

As the development of Liaohe Oilfield enters its middle and late stages, the number of oil wells with wellbore wear has been increasing year by year, making it difficult for the well fluid to be smoothly discharged inside the pipes. To address this common problem in the industry, the technical team of the Oil Production Technology Research Institute of Liaohe Oilfield conducted a comprehensive iterative optimization of the mature long-plunger sand control pump structure. They innovatively developed and installed an impact-type oil discharge device, relying on the principle of rod dropping gravity impact. By precisely dropping the rod at the wellhead, the stable opening of the downhole oil discharge channel can be achieved, enabling the rapid release of well fluid in the tubing during the pipe string lifting operation. This efficiently completes the operation process and completely avoids the interference of wellbore pipe wear on the oil discharge operation.

相较于传统工艺，携排砂泄油深抽举升技术不受井筒杆管偏磨工况影响，泄油作业全程平稳可控、安全可靠。截至目前，该技术历经40井次的先导试验和小规模现场试用，全方位提升了修井作业的安全性与施工效率。

Compared with traditional techniques, the deep pumping and sand discharge oil extraction technology is not affected by the uneven wear of the wellbore rods and pipes. The entire sand discharge operation is smooth, controllable, safe and reliable. Up to now, this technology has undergone 40 pilot tests and small-scale on-site trials, which has comprehensively enhanced the safety and efficiency of well workover operations.
