68 Domestic Shale Gas Mining Technology Research

Shale gas is a potentially huge resource of unconventional gas resources, with mining technology for high, mining, long life, stable long cycle characteristics. In recent years, a severe energy shortage situation and the rapid growth of energy prices, the shale gas resource in the world by a wide range of attention. In this paper, source rocks, reservoir conditions, gas shale cap rock and storage conditions, formation pressure and shale gas in terms of output characteristics of forming conditions and gas reservoirs are summarized overview, and the impact of shale gas. Development of the main factors to do a brief introduction. Summed up during the mining of shale gas reservoir evaluation technology, horizontal wells, logging, cementing and completion techniques and gas reservoir simulation technology and fracturing stimulation techniques to carry out the yield more thorough analysis and discussion, thought to horizontal well technology and fracturing stimulation technology current development process in the study of shale gas priority.
