常规岩性油藏注采比合理性评价

Rationality evaluation on injection-production ratio in unconventional Lithological Reservoir

注水开发是目前国内运用最为广泛的增产方法,其增产效果受到多方面因素影响,其中注采比是评价开发效果的重要指标之一;A油田为岩性油藏,目前处于全面开发阶段,注采井数比较大,为了提高注水开发效果,对其目前的注水开发现状进行评价;本文通过计算,评价注采比的合理性,为后期井网调整做参考。

Water injection development widely used to improve reservoir production in China is affected by multi-factors and injection-production ratio is one of the important indicators to evaluate the effect of development.This paper evaluates the current status of water injection development in the A reservoir and evaluates the rationality of injection-production ratio by calculation for late well pattern adjustment.
