蒲家沟地区为下寺湾采油厂主力产油区之一,在延长组长4+5、长6、长7和长8储层均见油气显示。针对研究区长6储层非均质性强的地质特征,通过对储层岩矿特征、孔隙特征、物性特征及储层渗流特征综合分析,认为研究区为典型的低孔特低渗储层,在后期开发中宜采用注水开发方式。 Pujiagou area is one of the main oil producing areas of Xiaanshanwan Oil Production Plant. Oil and gas are all seen in the extended 4 + 5, 6, 7 and 8 reservoirs. In view of the geological characteristics of reservoir 6 in Chang 6 area, through comprehensive analysis of the lithological and ore-bearing characteristics, pore features, physical properties and reservoir seepage characteristics, it is considered that the study area is a typical low-porosity and ultra-low permeability reservoir , In the latter part of the development should be used water injection development.
