摘要

三叠系地层是塔河油田主要的产油气储层之一。桑南三叠系中油组储层物性好 ,属高孔隙、渗透性好的储层。中油组储集岩孔隙主要受成岩作用影响 ,储集砂体的形成和分布主要受沉积环境控制。综合分析结果表明 ,桑南三叠系中油组主要有利储层发育区在研究区中部 ,而西南和北东部孔隙相对发育较差 ,不利于油气的聚集
Triassic formation is one of the hydrocarbon producing reservoirs in Tahe Oilfield. Reservoirs in Triassic mid member in Sangnan area are of good physical properties with high porosity and good permeability. Porosity of the mid member reservoir rock is mainly influenced by diagenesis, formation of reservoir sandbody and its distribution are mainly controlled by sedimentary environment. The result of integral analysis shows the main favorable reservoir growing area in the mid member of Triassic formation is in the middle of studied area, while porosity growing is relatively poorer in the southwest and northeast, which is unfavourable to hydrocarbon accumulation.
