摘要
以沉积学理论为指导,遵循地震与地质相结合的原则,从钻井资料入手,观察岩心及岩石薄片,结合相关化验资料,对单井相进行划分,进而划分剖面相,并对平面相展布特征进行分析。研究结果表明:昌德气田登娄库组物源主要来自区块北部、部分来自西部;沉积相类型以河流相为主,各小层沉积相平面展布表现出良好的继承性,登四段和登二段以曲流河沉积为主,登三段主要为辫状河沉积为主,砂体厚度相对较大,呈南北向条带状分布。
Guided by the theory of sedimentology and based on the combination of seismic,geological data and analysis of drilling data,core observation and thin slice,as well as related analytical data,single well was classified,consequently profiles were divided,and plain facies distributive characteristics were analyzed.The result shows that the sources of Denglouku Formation of Changde Gasfield are from the north and part of them are from the west,the sedimentary type is mainly of fluvial facies,the plane distribution of sedimentary facies of each sublayer presents good inheritance,the 4th and 2nd members of Denglouku Formation are mainly composed of meandering river sediment,the 3rd member is a braided river sediment with bigger thickness of sand,it is distributed in N-S trending stripes.
