摘要
针对水平井施工中井眼净化、井壁稳定、润滑防卡、保护油气层等技术难题,研制了高性能水基钻井液体系。通过对抑制剂、包被剂、降滤失剂等处理剂的优选,最终确定了高性能水基钻井液体系的配方,对该钻井液体系配方进行各项性能实验表明,该钻井液体系性能稳定,具有较强的抑制性、润滑性、抗污染性和油气层保护能力,在苏德尔特油田的苏平5井现场应用中井壁稳定,起下钻无阻卡现象,取得了非常好的施工效果。
A high-performance water-based drilling fluid system has been developed to solve the technical problems such as borehole cleaning, borehole stability, lubrication, anti-sticking and protection of oil and gas reservoirs in horizontal well construction. By the optimization of inhibitor, coating agent, filtrate reducer and other treatment agents, the high perform- ance water-based drilling fluid formulations are ultimately determined, the performance experiments show that this drilling fluid system has stable performance with strong inhibition, lubricity, anti-pollution and reservoir protection capability, very good construction effects have been achieved in the field application of well Suping - 5 of Sudeerte oilfield with stable wall, and no jamming in the tripping.
