摘　　要：我国低渗透油气藏规模较大,化学暂堵剂在低渗透油气藏的开发中发挥着显著的作用,目前已在国内取得了广泛的应用。按照组成成分来分,化学暂堵剂可分为交联聚合物类型、纤维类型、无机盐类型和复合类型。本文主要介绍暂堵剂的几种常见应用场景,并分类介绍几种暂堵剂的优缺点,对其研究进展进行综述。China's low-permeability oil and gas reservoirs are large in scale,and chemical temporary plugging agents play a significant role in the development of low-permeability oil and gas reservoirs,and have been widely used in China.According to the composition,chemical temporary plugging agents can be divided into cross-linked polymer types,fiber types,inorganic salt types and composite types.This article mainly introduces several common application scenarios of temporary blocking agents,and introduces the advantages and disadvantages of several temporary blocking agents,and summarizes their research progress.
