Zheng Lei, Du Yujiao, Liu Shuozhao, Wang Yonghong, Zhao Xiaomin

Abstract


Composite chlorine dioxide blockage relieving agent is a new type of well blockage relieving agent. It has strong abilities to oxidatively degrade polymers, kill microbial cells, dissolve sulfides, and dissolve inorganic salt minerals, which can effectively relieve blockages
in crude oil extraction channels. This paper introduces the properties of chlorine dioxide and its blockage relieving mechanism, and evaluates
its performance through viscosity reduction experiments, corrosion inhibition tests, clay stability tests, and bactericidal experiments.
