摘　　要：随着油田进入高含水期,生产中的各种矛盾凸显,油田递减速度加快.由平面、层间矛盾造成的边水、底水或注入水发生水窜、突破现象,使得油水过早见水,产量递减.如何减缓油田进入高含水期的产量递减达到稳产的目的成为愈来愈重要的关注点.化学堵水封堵水窜层成为缓解高含水期油井递减的主要方式之一,本文对M弱凝胶化学堵剂进行了性能评价,主要得出以下结论：凝胶体系由于酰胺基和羧基的作用而构成网状结构封堵储层;M弱凝胶化学堵剂对研究区岩心具有较好的封堵性,其封堵率分布在91％～94％.With the oil into the high water cut period,highlighting the various contradictions in the production of,oildecreasing speed. Water from the edge plane,interlayer conflicts caused by water or bottom water injection water breakthroughoccurred,breaking phenomenon,making premature water breakthrough oil production decline. How to slow down high water cutof oil production decline aim to achieve stable production becomes increasingly important concern. Chemical water plugging pluggingwater-channeling layer to become one of the main ways to alleviate high water cut of oil decreasing,the paper M weak gel chemicalblocking agent performance evaluation,mainly the following conclusions：Because amide gel system and the role of forming anetwork structure and a carboxyl group block reservoir; M weak gel chemical blocking agent on the core study area has good sealingproperties,blocking its distribution rate of 91% to 94%.
