摘要
中原油田采油二厂应用膨润土水泥体系进行水井调剖，但存在强度低，有效期短的弊病。本文应用 Ｍ Ｔ Ｃ（钻井液转变成固井水泥浆）和有机复合树脂后封口技术，对该体系进行改造，在充分的室内研究基础上，先进行４ 口井的现场试验，取得成功后，已推广应用６０ 井次。
MTC(Mud Change To Cement) and organic complex resin system is researched to enhance the profile modifacting with the old clay cement system.The new system is stronger and has longer effective life.Trials in four wells is presented and successful usage in 60 wells is stated in the end.
