摘　　要：针对辽河油田双南等地区井壁不稳定问题，研制了一种硬脆性泥页岩井壁稳定剂──ＪＨＳ。这是一种含阴、阳、非离子和有机硅等基因的多元共聚物。室内研究结果表明，ＪＨＳ对辽河油田沙河街组硬脆性泥页岩具有很好的稳定性能，其２４ｈ径向膨胀率较稳定剂Ｋ－ＰＡＭ等可降低１０％左右，热滚回收率较Ｋ—ＰＡＭ等约提高１０％以上。A kind of borehole stabilizer, JHS, for hard and brittle shales is developed for solving the problem of instability of borehole in the Liaohe field. It is a copolymer containing negative and positive ions,nonionic and organic silicon groups as well as potassium ion etc. Tests for evaluating the JHS performance demonstrate its stabilityfor the hard and brittle shales in the Shahejie formation, Liaohe field, better than other stabilizers. It has a radial swelling ratio in 24 h lowered by 10% or more and a recovery ratio by heat rolling increased by 10% or more, compared with the stabilizer K-PAM and others.
