INJECTION INCREASE TECHNOLOGY IN UNCONVENTIONALITY FRACTURING WATER INJECTION WELL

This paper studies and analyzes the faultiness of the conventionality water well fracturing theory during applying in how to improve the sweep efficiency and how to reduce water breakthrough, and bring forward a set of applied technique about water injection increase of unconventionality fracturing technique. Reservoir engineers have been simulated and calculated the fracture length of unconventionality fracturing well. After the set of technique has been applied in 6 wells, excellent results are obtained.This paper sets up a kind of realizable technique that can improve water injection.
