葫芦河区块构造位于陕北斜坡的南部,三叠系延长组地层发育,长6层是主要开发层位。本文通过对该区长6层地层对比、小层划分、沉积相、储层特征、储层评价、砂体展布、油藏类型等地质特征进行研究,分析认为该区长6层砂体分布稳定、油层厚度大,具有一定的规模建产潜力。
The Huluhe block is located in the southern part of the northern slope of Shaanxi Province. The Triassic Yanchang Formation has a stratigraphic development and the 6th long layer is the major developmental horizon. Based on the study of the stratigraphic contrast, small division, sedimentary facies, reservoir characteristics, reservoir evaluation, sand body distribution and reservoir type in the area, the paper analyzes the geological distribution of 6 layers of sand body Stable, thick oil layer, with a certain scale of production potential.
