Shale gas development has extensive geological significance

Shale gas development has extensive geological significance, exists in nearly all of the basin, but due to large buried depth, gas saturation difference respectively have different industrial value. Chinese traditional sense of the fracture of the shale gas, shale reservoirs, shale fracture reservoirs, fractured reservoirs is fracturing proppant with this pretty, but I did not consider which does not take into account the adsorption mechanism of the primary attributes of natural gas, and understanding on the subject for free phase of gathered in the cracks of the shale oil and gas. Therefore belongs to incomplete in the sense of shale gas. As a result, China's concept of mud shale fractured reservoir in today's connotation of shale gas is not identical with the United States, respectively in the hydrocarbon source of material content, storage phase, are large differences in the characteristics and composition of China's major basins and regions shale gas resource is about 15 trillion - 30 trillion cubic meters, 28.3 trillion cubic meters of the same with the United States, a huge economic value. On the other hand, long production period is also a remarkable characteristics of shale gas. Shale gas frac sand companies life generally up to 30 ~ 50 years, or longer. The federal geological survey according to the latest figures, the United States in fort basin Barnett shale gas field production life of up to 80 ~ 80. Mining long life, means that the value of development and utilization of large, it also determines its development potential. Shale gas
