摘要: 东濮凹陷是渤海湾盆地中惟一个既富油又富气的凹陷,该凹陷的发育经历了前断陷期、断陷期和坳陷期三个发育阶段,发育上古生界和下第二系两套烃源岩,可形成煤型气和油型气,由于两套气源岩不同,生成的天然气组分及地球化学特征差异大.根据圈闭类型,储气层产状、天然气地下存在方式、储集空间、天然气成因、水动力条件、所处构造层等对东模凹陷天然气藏进行分类,并按天然气成因分析了天然气分布规律,划分出古生界-沙四段、沙三-沙二段和上第三系三大成气系统,指出环洼带是寻找下第三系油型气的有利区域,中央隆起带南部和文-卫地伏古生界是寻找上古生界煤型系的有利目标区.

关键词: 东濮凹陷, 天然气成因:气藏类型, 分布规律, 地质特征

Abstract: Dongpu Depression is the unique one in Bohai Bay Basin concurrently abundant of oil and nature gas resources. Development of the depression has experienced three stages of pre-rift-subsidence, rift-subsidence and depression.Two sets of nature gas source rock were developed in Upper Paleowic and Eocene during three evolution stages that could be formed coal gas and oil gas. Due to the difference of the two sets of gas source rocks, the component and geochemical feature for the generated natural gas varied significantly. The paper classifies natural gas reservoir in Uongpu Depression on the basis of following factors: type of the trap, reservoir occurrence, reservoir rock altitude,genesis of natural gas,hydrodynamic condition and the structure formation location. Three natural gas bearing intervals are identified.The paper also predicts favorable target canes in the area.

Key words: Dongpu Depression, genesis of natural gas, type of natural gas reservoir, distribution rules
