摘要: 为了解决川西致密碎屑岩气田存在的生产动态复杂、储量难动用、采速低、见产慢、稳产条件差、提高综合开采效益困难等问题和难点,通过研究和现场试验,认为采用整体压裂改造开发技术可以获得较好的产能和经济开发效果。建立了气、水三维二相三重介质低渗致密裂缝性气藏整体压裂模拟模型,模型中首次全面考虑了低渗致密气藏低速非达西型渗流和高速非达西型渗流的影响,结合地应力研究,对新场上沙溪庙致密碎屑岩气田整体压裂开发方案进行了设计研究;为低渗致密气藏整体压裂改造方案的编制提供了思路和工具。

Abstract:

It is difficult to obtain more reserve to increase well capacity and make a considerable profit due to such problems that exist in the tight clastic gas reservoir of Xinchang gas field as complex production performance, low recovery rate and short stablproduction time. According to lab research and pilot test, fracturing reservoir technology is applicable in tight clastic gas reservoir, which can remarkably improve gas production. In this paper an improved new fracturing reservoir mathematical model ipresented for tight gas reservoir of low permeability by takin both low non-Darcy flow and high non-Darcy flow into account. Based on the model above, a fracturing reservoir plahas been worked out for upper Shaximiao Group reservoir in thpilot area of Xinchang gas field.

Key words: fracturing reservoir, production performance, tight clastic gas reservoir, natural fracture, Xinchang gas field
