中国石油网消息：截至8月5日，新疆油田首个CCUS试验区，经过多功能药剂开展短检泵周期专项治理的油井，最长已稳定连续生产378天，平均检泵周期达到50天，该项成果标志着CCUS区块短检泵综合治理工作取得关键性重大突破。

China Oil News: As of August 5th, the first CCUS experimental area of Xinjiang Oilfield, after undergoing special treatment of oil wells using multi-functional agents for short inspection pump cycles, has achieved the longest stable continuous production of 378 days, with an average inspection pump cycle reaching 50 days. This achievement marks a crucial and significant breakthrough in the short inspection pump comprehensive treatment work of the CCUS block.

八区530克下组油藏二氧化碳混相驱试验区作为新疆油田首个CCUS示范区，随着碳驱逐渐见效，受井筒高气液比、结蜡等多重因素影响，人工举升检泵周期急剧缩短，修井作业频繁，油井生产时率持续走低，成为制约高效开发的技术瓶颈。

The 530-kilogram lower group oil reservoir carbon dioxide miscible flooding experimental area in the 8th district serves as the first CCUS demonstration zone in Xinjiang Oilfield. As carbon flooding gradually takes effect, due to multiple factors such as high gas-liquid ratio in the wellbore and wax deposition, the inspection pump cycle for artificial lift has sharply shortened, well repair operations have become frequent, and the production rate of oil wells has continued to decline, becoming a technical bottleneck restricting efficient development.

针对这一难题，新疆油田采油工艺研究院（监理公司）2025年起将试验区短检泵综合治理列为重点攻关任务，联合采油二厂、开发公司等单位组成联合攻关项目组，系统分析CCUS油井腐蚀、结垢、析蜡规律，确立了以物理干预与化学治理为主体、生产制度协同优化的技术路线。

To address this challenge, the Oil Production Technology Research Institute of Xinjiang Oilfield (the supervision company) designated the comprehensive treatment of short inspection pumps in the experimental area as a key research task starting from 2025. They jointly formed a joint research project team with the Second Oil Production Plant and the Development Company, etc. They systematically analyzed the corrosion, scaling, and wax precipitation patterns of CCUS oil wells, and established a technical route mainly based on physical intervention and chemical treatment, while coordinating the optimization of production systems.

在物理干预方面，攻关研发特种合金防垢防蜡工具，利用合金材料电化学特性，改变流体的物理特性，从源头改变结垢和析蜡环境；在化学治理方面，针对试验区油井腐蚀、结垢、结蜡复杂工况，优选缓蚀剂、阻垢剂、防蜡剂并进行多功能药剂复配，对井筒实施全方位防护。与此同时，针对试验区工况特点，同步优化生产制度，合理调整抽汲参数，改善抽油泵工作条件，有效减轻气蚀和泵磨损。

In terms of physical intervention, efforts are made to develop special alloy anti-scaling and anti-waxing tools, leveraging the electrochemical properties of the alloy materials to alter the physical properties of the fluids, thereby fundamentally changing the conditions for scaling and wax precipitation. In the chemical treatment aspect, for the complex working conditions of oil wells in the experimental area such as corrosion, scaling, and wax deposition, preferred corrosion inhibitors, scale inhibitors, and wax inhibitors are selected and multi-functional agents are compounded to provide comprehensive protection for the wellbore. At the same time, in accordance with the characteristics of the experimental area's working conditions, the production system is optimized, the pumping parameters are adjusted reasonably, and the working conditions of the pumping unit are improved, effectively reducing cavitation and pump wear.

2025年下半年至今，采油工艺研究院（监理公司）在试验区累计推进特种合金短节、多功能药剂、气液置换防气泵配套多效复合气锚一体化携气举升3项工艺试验26井次，截至目前，试验井平均生产213天，措施效果显著且持续有效。从检泵频次分析，今年上半年，全区累计检泵仅5井次，较2025年同期降低83.9%，成功扭转了试验区检泵周期自2023年以来持续缩短的被动局面。

Since the second half of 2025, the Oil Production Technology Research Institute (construction company) has conducted a total of 26 well trials for three technologies in the experimental area: special alloy short sections, multi-functional agents, and gas-liquid replacement gas pump with multi-effect composite gas anchor integrated gas lifting. As of now, the average production duration of the test wells is 213 days, and the measures have achieved remarkable results and remain effective. Analyzing the pump inspection frequency, in the first half of this year, the total number of pump inspections in the entire area was only 5 wells, a decrease of 83.9% compared to the same period in 2025. This has successfully reversed the passive situation where the inspection cycle in the experimental area has been continuously shortened since 2023.
