摘要
海115区块位于吉林省松原市乾安县境内,区块自2009年开发动用以来暴露了诸多问题,对区块沉积微相刻画提出了更高的要求。本研究根据沉积微相划分的一般经验,主要利用区域岩相古地理研究成果,分析区域沉积背景,结合岩心观察和分析化验资料以及测井相分析资料,划分大相、亚相,进而划分微相。结果表明研究区青一段为三角洲前缘沉积体系、泉四段为三角洲沉积体系,并进一步划分出水下分流河道等五类微相。
Hai115 block is located in Qianan county,Songyuan city,Jilin province.Since it was exploited in 2009,it has exposed many problems,which put forward higher requirements for sedimentary microfacies characterization of the block.In this study,according to the general experience of sedimentary microfacies division,mainly using regional lithofacies paleogeography research results to analyze the regional sedimentary background.In combination with Core observation and analysis of laboratory data and log analysis data,large facies and subfacies are divided,and then microfacies are divided.The results show that qing1 member is delta front depositional system,quan4 member is delta depositional system,and further divided into five types of microfacies such as underwater distributary channel.
