| Abstract: | Plug removing and acid backflowing technology through pressure drop is developed based on jet principles to solve the problems of formation plugging near wellbore zone ahd acid backflowing. The technological pricinples, selection of papameterstechnological characteristics and field application are discussed in this paper. Field data show that it can effctively drain off the residual acid,reaction products of acid and various foreign substances and lessen formation contamination. |
