美国页岩气体积改造技术现状及对我国的启示

The current situation of stimulated reservoir volume for shale in U.S. and its inspiration to China

概述了美国页岩气改造技术发展历程,对微地震技术推动页岩气改造技术的进步进行了综述,对国外提出的油藏改造体积概念进行了技术定义,分析了体积改造技术的内涵及作用。对实现体积改造的储层条件、天然裂缝的影响及起裂特征等进行了分析,总结出实现体积改造的关键技术以及对我国页岩气改造技术发展的启示。对比了火山岩、碳酸盐岩等天然裂缝发育储层的常规改造与体积改造的不同理念,并提出了页岩气储层改造技术未来发展方向。

This paper briefly illustrates the development process of the Stimulated Reservoir Volume（SRV） for shale gas reservoir in U.S.was briefly illustrated,and how micro-seismic technique drove shale gas reservoir stimulation to develop was given.First,the concept of SRV proposed by abroad is defined technically,and then the connotation and function of SRV technology are analyzed;sec-ond,the reservoir conditions,the effect of natural fractures and the characteristic of starting crack are illustrated and then the key points of SRV implementation and its enlightenment to the development of China’s hale gas reservoir stimulation technology is summarized,finally,the differences between conventional stimulation for natural fractured reservoirs such as volcanic rock and carbonate rock and SRV technology are coMPared,and the further development of the SRV for shale gas reservoir is addressed.
