摘要:
化学暂堵剂普遍应用于石油开采及油水井的改造作业中。 随着对暂堵剂的深入研究,开发出的暂堵剂品种 也日益丰富。 本文主要根据暂堵与解堵方式将暂堵剂划分为碱溶性、酸溶性、油溶性、水溶性。 基于此种分类方法总结了不同种类暂堵剂的研究进展,并总结了其在应用过程中存在的优缺点。 此外,本文还针对暂堵剂的不同应用场景进行了总结研究。

Abstract：
Chemical temporary plugging agents are widely used in oil exploration and reconstruction of oil and water wells. With the in-depth research on temporary plugging agents, the varieties of temporary plugging agents developed are becoming more and more. In this paper, the temporary plugging agents are divided into alkali-soluble, acid-soluble, oil-soluble and water-soluble according to the temporary plugging and plugging removal methods. Based on this classification method, the research progress of different types of temporary plugging agents is summarized, and their advantages and disadvantages in the application process are summarized. In addition, this paper summarizes and studies the different application scenarios of temporary plugging agents.
