徐深气田中基性火山岩储层岩石致密、物性极差,但这部分储量非常大,采用常规压裂改造技术难以实现经济有效开采。针对这一问题,本文通过地质及工艺分析,优选W1井开展先导性试验,采取纤维暂堵压裂改造技术,选用可降解纤维,在W1井试验应用,增气效果对比临井非常明显,下一步具有很大推广应用价值。
The rocks of the medium-basic volcanic reservoirs in the Xushen gas field are very tight with very poor physical properties. However, this part of the reserves is very large. It is difficult to economically and effectively mine using conventional fracturing technologies. In response to this problem, this paper through the geological and technological analysis, the preferred well to carry out the pilot pilot test to take fiber temporary plugging fracturing transformation technology, selection of biodegradable fibers, in Well W1 test application, One step has great promotion and application value.
