低渗气田产水气井聚丙烯酰胺堵剂配方研究

Study on polyacrylamide plugging agent formula for water-producing gas wells in low permeability gasfields

本文针对苏里格气田地层情况,研究在不同渗透率、不同含水饱和度下采用不同堵剂配方时的封堵率。结果表明,该试剂具有明显的选择性堵水效果,对低渗高含水气田堵水的研究以及更好的解决气井堵水的相关问题提供了重要依据。

According to the status of gas formation in Sugeli gas field,this paper uses different plugging agent formula to study the plugging rate under different permeabilities and different water saturation.The results show that this reagent has obvious selective water plugging effect,and provide an important basis for the water plugging study of gas fields with low permeability and high water content,and solving the related problem of gas well water plugging effectively.
