针对常规水井压裂理论在实际应用中施工周期长、强度大、成本高、容易形成水窜和二次污染等问题,研究了注水井非常规压裂增注技术。模拟计算出非常规压裂的造缝长度,对60井进行了试验,取得了明显的效果,为提高注水井注入效果提供了一项实用有效的技术。

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.
