中国石油网消息：6月1日，从西部钻探公司了解到，这个公司井筒工作液处理剂合成创新团队取得科研突破，自主研发的JNP-Ⅱ抗复合盐聚合物降滤失剂完成室内配方定型，破解了高端钻井液处理剂长期外购难题，补齐企业150摄氏度水基钻井液自研体系关键短板，产品整体性能达到国内领先水平，实现该类核心技术自主可控。

China Petroleum Network News: On June 1st, the wellbore working fluid treatment agent synthesis innovation team of the Western Drilling Company announced a scientific research breakthrough. The domestically developed JNP-II anti-complex salt polymer fluid loss reducer has completed the indoor formulation stabilization, solving the long-standing problem of relying on external purchase for high-end drilling fluid treatment agents, filling the key gap in the enterprise's self-research system for 150-degree water-based drilling fluids, and achieving overall performance at the domestic leading level, realizing the independent control of such core technologies.

在150摄氏度中高温深井钻井作业中，降滤失剂是保障钻井液体系稳定、井壁安全的关键材料。长期以来，国内高端抗盐降滤失剂依赖外购，制约了高端水基钻井液自主化发展。

In high-temperature deep well drilling operations at 150 degrees Celsius, the anti-filtering agent is a crucial material for ensuring the stability of the drilling fluid system and the safety of the well wall. For a long time, domestic high-end anti-salt anti-filtering agents have relied on imports, which has restricted the independent development of high-end water-based drilling fluids.

针对这一行业技术痛点和生产瓶颈，该创新团队聚焦高温环境下钻井液黏度调控与降滤失性能难以兼顾的行业共性难题，开展海量配方筛选、变量试验与千余次迭代试错，逐一攻克复合盐干扰、高温老化失效、体系异常增黏等关键技术卡点，优化完善聚合配方与生产工艺。

In response to the technical pain points and production bottlenecks in this industry, this innovative team focused on the common industry problem of difficultly balancing the viscosity regulation and anti-filtering performance of drilling fluids under high-temperature conditions. They conducted extensive formula screening, variable experiments and over a thousand iterations of trial and error, and successfully overcame key technical obstacles such as interference from composite salts, aging and failure at high temperatures, and abnormal increase in viscosity of the system. They optimized and improved the polymer formula and production process.

最终，该处理剂成功定型，扭转了西部钻探高端抗盐降滤失处理剂依赖外购的被动局面，填补了企业高端钻井液处理剂自研领域空白，打通了深井钻井液体系全链条自研的关键环节。

Ultimately, this treatment agent was successfully developed and refined, reversing the passive situation where the company relied on external purchases for high-end anti-salt and low-filtering-loss treatment agents. It filled the gap in the enterprise's self-research in the field of high-end drilling fluid treatment agents and opened up the key links in the entire chain of self-research for deep well drilling fluid systems.
