针对中低渗透储层黏土含量较高的实际情况,研究了适用于该储层注水开发的防膨剂.通过与注入水及地层水的配伍性实验和防膨试验,评价了防膨剂在不同浓度下的防膨效果.提出了现场注水用的防膨剂在其使用浓度为2％时防膨效果较好.并且现场数据显示应用选用的防膨剂后,区块注水开发取得了较好效果.%The water flooding anti-swelling protective agent is studied which applies to the low permeability reservoir with high clay content. Through the experiments of injection water, formation water compatibility and anti swelling test, evaluated the effect of the anti-swelling agent in different concentrations, put forward the effect of anti-swelling agent at the concentration of 2% used in the field is good. And field data show with the application of the anti swelling agent, block development achieved good results.
