摘　　要：开38块位于辽河盆地东部凹陷的南部,主要的含油层系沙一段地层向中央凸起超覆尖灭,沉积相属于扇三角洲沉积,在区域构造沉积背景下形成一系列的岩性圈闭,该块为开发20年的老区块,对油藏的认识不清导致该块储量采出程度低,深入认识油藏的分布特征有利于改善区块的开发效果.Block Kai38 is located in the southern part of the eastern depression of Liaohe Basin.The first member of the Shahejie Formation of the main oil-bearing formation overlap and pinch out toward the central uplift.The sedimentary facies belongs to fan delta deposits,forming a series of lithologic traps under the background of regional tectonic deposits.This block is an old block which has been developed for 20 years.The unclear understanding of the reservoir leads to the low recovery of the reserve in this block.A thorough understanding of the distribution characteristics of the reservoir is conducive to improving the development effect of the block.
