致密气藏开采技术初探

An approach to recovery technique of tight gas reservoir

优化的布井方式和压开最合适的裂缝是开发方案的重要环节 ,对致密气层获得扩大的可采储量、天然气采收率和提高日产量有决定性作用。在确知水力裂缝方位的情况下 ,采用相应的矩形方式布井将会对提高可采储量和天然气的采收率起重要作用。随着测地应力和监测方法与技术的发展、深入研究储层性质以及模型研究的扩大 ,构成了综合分析系统 ,形成了“现代化的”

Optimum pattern of spacing and suitable fracturing are important points of a development plan, and play decisive role for increasing recoverable reserves, gas recovery factor and daily production of tight gas reservoirs. With knowledge of hydraulic fracturing azimuth, adequate rectangular pattern will be helpful for improving recoverable reserves and gas recovery factor. As the development of terrestrial stress measuring, monitoring, and reservoir property and model study, an integrated analysis system has been established, thereby forming'modern'fracturing techniques.
