胜北洼陷深盆气成藏条件分析及勘探方法研究

THE STUDY OF DEEP BASIN GAS RESERVOIR GENERRATION CONDITIONS IN SHENGBEI DEPRESSION AND ITS EXPLORATION METHODS

经对胜北地区与国外已知深盆气藏的地质条件的类比,分析论证了胜北地区深盆气藏成藏的地质条件,同时通过对该区的深盆气藏勘探方法的探索,地质分析与地球物理识别方法相结合,认为胜北地区的深盆气藏分布在3000以下的J_2s以下的层位,呈以不对称方式分布在以台参2井和胜深3井为中心,向恰勒坎抬升的斜坡带上。

The geologic conditions of forming deep basin gas reservoir in Shengbei area have been studied by comparing geologic conditions with the given deep basin gas reservoirs aboard, and it is concluded that the Shengbei region had the geologic conditions of generating deep gas reservoir. The most favorable zone for deep basin gas reservoir is believed to be below the J_2s over 3000m deep, on an asymmetrical slope belt ascending toward Qialekan with Well Taican2 and Shengshen3 in the center.
