摘要
The effect of geological basis and structural compression on the abnormal pressure in the Feixianguan Formation is studied on the basis of relationship between the stratum pressure and the character of gas reservoir. It is considered that the development and closure of gypsum layers in the Leikoupo Formation of Mid Triassic and the Jialinjiang Formation of Upper Triassic are the geological basis for the formation of high abnormal pressure, and the structural compression during the Late Yanshan Movement and Himalayan Movement is the major reason for the formation of abnormal high pressure.
