摘要

为搞清辽河坳陷东部凹陷沙三段根缘气的分布规律,在对根缘气聚集基本条件分析的基础上,主要利用测井、录井等资料证实了根缘气的存在,分析了气测全烃值、埋深和厚度的分布特征,并结合源岩和储层条件预测了有利发育区。研究表明,东部凹陷南部和北部根缘气的气测全烃值、埋深和厚度较大,中部较小。北部的牛居、茨榆坨和南部的黄金带、大平房、荣兴屯等地区为根缘气有利发育区。

Abstract

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.
