摘　　要：分析川西地区低渗透致密砂岩气藏的物性特性和孔喉尺寸,计算与川西地区储层孔喉匹配的小分子量聚合物粘土稳定剂分子量控制范围。通过合成优化实验,合成出一系列不同分子量的粘土稳定剂产品。通过静态和动态实验对该系列粘土稳定剂与川西地区储层孔喉尺寸的适应性进行综合评价。On analysis of the low-permeability rock material properties and the pore throat size of tight sandstone gas reservoirs in Western Sichuan,this paper firstly works out the range of clay stabilizer molecular weight which math with the pore throat in Western Sichuan,and through the synthesis optimization experiment,synthesized a series of different molecular weight clay stabilizer product. Then it has carried on the adaptability study between a series of clay stabilizer and the pore throat size in Western Sichuan through the static and dynamic experiment.
