Research and Applications on the Theory of Shale Gas Depth Enrichment Zone

Abstract:

Shale gas is one of unconventional natural gas reservoirs,with forming pattern of self-generating and self-preserving. The research indicates that the distribution characteristics of shale gas content is influenced by the factors of the depth,the structure shape,the total carbon organic and the physical property of shale reservoir. The shale gas is on dynamic balance among the adsorbed gas, the free gas and the dissolved gas. By the exploration and development of shale gas,we obtained important theoretical understanding that there exists a parabola model relation between the shale gas content and the depth of shale reservoir,which is called L-W model of enriched accumulation belts of shale depth. Theory and practice studies show that the synclinal layer is the main structural factors controlling the enrichment of shale gas. Therefore,in the background of stronger geological tectonic movements in our country, finding weak tectonic area such as the synclinal layer formation occurrence,is the exploration direction for determination of favorable target areas of shale gas.
