Research and Application on Homogeneous Acidification to Enhance Producing Degree of Horizontal Wells

The homogeneous acidification technology for Horizontal well is developed to solve the problem of serious pollution in near wellbore area owing to long-time mud soak and large contact area of injected fluid. It not only reduces cost, but also improves acidification efficiency and controllability of horizontal wells. Through field experiments, the technology has got great achievements on eliminating well pollution and increasing productivity.
