页岩气资源分布、开发现状及展望

目前页岩气资源勘探开发已成为世界焦点，研究表明世界页岩气的资源量为636.283×1012 m3。美国页岩气资源丰富，广泛分布于美国的南部、中部及东部。中国也拥有丰富的页岩气资源，据初步评价与美国页岩气资源量大体相当，但目前我国页岩气开发还处于初级阶段。美国是页岩气勘探开发技术最先进，开发最全面的国家，加拿大也有较长的页岩气开发历史。由于页岩气储层渗透率低，开采难度大，因此我们需要学习国外先进技术，开发一套适合我国页岩气储层的钻井开采工艺，同时需要国家的大力支持，推动我国页岩气产业的发展。

THE DISTRIBUTION,DEVELOPMENT AND EXPECTATION OF SHALE GAS RESOURCES

The exploration of shale gas resources becomes a focus of the world. The natural gas resources are 636.283×1012 m3 in the world. Shale gas resources are rich in America, most of them are distributed in southern, central and eastern parts. There also are plenty of shale gas resources in China, nearly the same quantity as in America. In America there is the most advanced exploration and exploitation technology, and it is the only country which has the highest exploitation method. Canada has a long history of shale gas exploration and exploitation. China is still at the beginning for the shale gas exploitation. The permeability of the shale rocks is normally very low, so it is difficult to be exploited. Therefore, we need to learn the advanced foreign technology to develop a set of exploitation methods to develop our shale gas reservoirs, and we need the support from the government, increasing environmental protection while development.
