中文摘要:探采结合水井需要实现精确获取水文地质参数和解决百姓饮水难题的双重目的,因此要求钻进施工中采用的冲洗液既要具备基本的护壁防塌等功能,还需最大程度地降低对地层渗透性的影响,同时还应具有优良的环保性能。针对这一特殊要求,研发了新型的PA—1型无固相环保冲洗液,采用渗透性实验、电镜扫描、砂球浸泡实验等多种测试手段对冲洗液进行了室内评价与分析,结果表明PA—1型无固相环保冲洗液对地层渗透性影响较小,防塌护壁能力强,综合性能优于常规冲洗液体系;采用中华米虾对其进行急性毒性实验也表明其安全无毒。大量室内实验及现场应用表明,PA—1型无固相环保冲洗液各项性能优良,可为今后在探采结合水井施工中冲洗液的合理选用提供参考。

Research and application of solid free environment friendly drilling fluid for exploration and production well drilling
Abstract:Exploration and production wells need to achieve the dual purpose of accurately obtaining hydrogeological parameters and solving the problem of drinking water for the people. Therefore, when rotary drilling technology is adopted, the flushing fluid is required not only to have basic wall protection and anti-collapse functions, but also to minimize the impact on formation permeability, and also to have good environmental protection.. According to this special requirement, a new PA-1 type solid-free flushing fluid solution was developed, also, the permeability test, SEM and sand ball immersion test were used to evaluate and analyze the flushing fluid in the laboratory, The results show that PA-1 solid-free flushing fluid has little influence on formation permeability and strong ability to prevent collapse, Which comprehensive performance is superior to the conventional flushing fluid system; In addition, the acute toxicity test of Chinese rice shrimp showed that it was safe and non-toxic. Therefore , a large number of laboratory experiments and field applications show that PA-1 solid-free flushing fluid has excellent performance,which can provide a reference for the selection of flushing fluid in Exploration and production well construction in the future.
