摘要:

针对渤海垦利10-1油田群钻井过程中穿越多层位,很难解决东营组、沙河街组井壁坍塌、掉块,井壁失稳的问题,通过延续活性软泥页岩井壁稳定机理,选择易调控处理剂提高抑制性,坚持上部地层软抑制、下部地层强抑制概念,引入一种聚胺类抑制剂PF-HAS替代有机正电胶PF-JMH-YJ。该材料对软泥岩适度抑制,又能与KCl兼容,既解决了传统PEC体系流变不易控制,又解决了起下钻阻卡问题,减少了复杂情况的产生;而且由于其与PEM体系兼容性好,使得PEC体系与PEM体系可以兼容,为同时钻穿明化镇组、馆陶组、东营组直至沙河街组节省了一层套管,大大提高了作业时效,对渤海区块其他油田的钻井作业具有重要的指导意义。

In the process of going through multi-layers in drilling of Bohail Oilfield Group, it was difficult to solve the problems of wellbore collapse and falling off and wellbore instability in Dongying and Shahejie Formations. By continuously using active and soft mud shale borehole stability mechan-ism, an easy control treatment agent was chosen to improve the inhibitory, adhere to the concept of soft restrain in the upper strata and strong inhibition in the lower formation, a kind of polyamine inhibitor PF-HAS was used instead of PF-JMH-YJ, PF-HAS was moderately used for inhibition to the soft mudstone, and compatible with KCl, by which the problems of hard control of rheology in traditional PEC system and drilling pipe stuck in tripping were solved and complications in drilling were reduced. Because of its good compatibility with the PEM system, the PEC system can be compatible with PEM system, at the same time, a layer of intermediate casing for drilling in Ninghuazhen Formation, Guantao Formation, Dongying and Shahejie Formations is saved, it greatly improves the operation efficiency, and it provides an important guidance for the drilling operations in the other oil fields in Bohai Area.
