Abstract

The exploration of shale gas was firstly put into practice in USA. Shale gas is a kind of unconventional natural gas, which mainly accumulates in adsorbed and free phases. Shale gas is characterized by insitu accumulation, and controlled by the thickness and distribution, organic geochemical characteristics, porosity and permeability, fracture development and seal conditions of the shale. The shale of Yanchang Formation is widely distributed in Ordos Basin, and is characterized by big thickness, high TOC, moderate thermal evolution, popping gas survey, and well developed fractures. The preliminary research shows that the south Ordos Basin is the favorable area of the shale gas development of Triassic Yanchang Formation, and the “L-type” area of Dingbian\|Huachi\|Fuxian is the most favorable area for the shale gas development. The shale gas potential decreases gradually outwards to the surrounding area.
