A Primary Study on Distribution Pattern of Source-Contacting Gas Accumulation for the Third Section of Shahejie Formation in the Easten Sag of Liaohe Depression
辽河坳陷东部凹陷沙三段根缘气分布规律浅析

For knowing the distribution Pattern of Source-Contacting Gas Accumulation for the Es3 in the Easten Sag of Liaohe depression, based on analyses of gas fundamental accumulation conditions, the existence of source-contacting gas is proved mainly by log and well log data.Combined with an analysis of source rock and reservoir, the paper also discusses the distribution of total gas curve, burial depth and thickness, and predicts the potential development area. It is indicated that total gas curve, burial depth and thickness are larger in the south and north of eastern sag and smaller in the middle. Niuju, Ciyutuo and Huangjindai in the north and Dapingfang, Rongxingtun in the Sorth are potential development area.
