构造转换带对塔南凹陷滑塌浊积岩油藏的控制

摘要

通过塔南塔19-78井区的岩屑录井、岩心及地震资料的综合分析,系统研究了塔南凹陷滑塌浊积砂砾岩油藏的储集层及其地震反射特征。在此基础上,结合塔南凹陷南屯组沉积期的构造特征,重点探讨了构造转换带对于滑塌浊积体分布及其所形成油藏的控制作用,认为转换带内的油藏分布受构造和岩性的双重因素控制。结合完钻井的试油生产数据,对该套滑塌浊积砂砾岩油藏的潜力进行了初步分析。%Through composite analysis of core logging,core lab data and seismic profile in T19-78 well area of Tanan sag in Tamuchage basin,the slump turbidite glutenite reservoir and seismic reflection characteristics are studied systematically.Integrated with structural feature of the Nantun formation in this sag,the structural transformation zone control of the distribution of slump turbidite and reservoir is mainly discussed.It is recognized that the distribution of reservoir in the transformation zone is controlled by both structure and lithology Finally,based on the production test data from drilled wells,the preliminary analysis of such reservoir＇s potentials is made.
