| Popis: | chemical flooding and separate injection has entered the stage of large-scale popularization and application. With the deepening of development, the number of separate injection wells is increasing year by year, and the test workload is increasing continuously. Because the test and adjustment period of chemical flooding wells is shorter than that of water flooding, the test workload and test pressure are further increased The electric sealing and fishing technology is adopted to realize the electric control direct reading in the whole process of sealing, bailing and adjustment of chemical flooding wells, and the efficiency of measurement and adjustment is further improved. This paper introduces the process principle, technical characteristics and application effect of electric sealing and fishing technology of chemical drive.
