在社会经济不断发展,资源需求总量不断增多的今天,开发气藏也变得愈发的重要。但在开发气藏的过程中,流体和气藏储层接触面就会出现一定程度储层损害问题。就致密煤气层来看,其在井压裂施工期间,压裂液会可能会损害储层,从而导致开发效果无法达到预期。对此,本文以致密煤岩为切入点,通过实验研究的方式,对压裂液造成的气藏储层损害问题展开分析。
As socio-economic development continues and the total demand for resources increases, the development of gas reservoirs has become increasingly important. However, in the process of developing gas reservoirs, there will be a certain degree of reservoir damage problem at the contact surface of fluid and gas reservoir. For the tight gas layer, fracturing fluid may damage reservoirs during well fracturing, resulting in failure to achieve the desired result. In this paper, the paper takes the dense coal rock as the breakthrough point, through the experimental study, analyzes the reservoir damage caused by the fracturing fluid.
