葫芦河区块三叠系长6储层地质特征研究

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。

Research on Triassic Chang 6 Reservoir Characteristics in Huluhe Oilfield

Huluhe oilfield geological structures is located in the southern slope of northern Shaanxi; Triassic Yanchang reservoir developed;Chang 6 is a major development reservoir. In this paper, through study on stratigraphic correlation, small layer division, sedimentary facies, reservoir characteristics, reservoir evaluation, sand distribution, reservoir types and other geological features, Characteristics of Chang 6 reservoir was analyzed. The results show that the sand distribution of Chang 6 reservoir is stable, reservoir thickness is big, so it has a certain scale development potential.
