鄂尔多斯盆地罗庞塬油区长8储层油层组尚未取得重大发现,其储层物性较差,成岩作用复杂,导致储层非均质性较强,因此对其储层特征的研究工作已成为研究重点之一。本文根据鄂尔多斯盆地罗庞塬油区长8区域地质背景,分别对其区域范围之内的测井、录井、岩心和试油等资料进行了整理和分析,结合铸体薄片和扫描电镜等实验观察资料,解释制作出相关图件,对研究区长8储层的岩石学特征、物性特征、岩性与物性特征等作了较为详细的描述,为有利区划分服务。
The reservoir of Chang 8 reservoir in LuoPongyuan oilfield in the Ordos Basin has not been found yet. Its reservoir properties are poor and its diagenesis is complex, leading to strong reservoir heterogeneity. Therefore, the study of its reservoir characteristics has become One of the research focuses. According to the geological background of Chang 8 area in LuoPongYuan oil region of Ordos basin, the paper analyzes and organizes the logging, logging, core and oil testing in the region of the area, and combines the experiment of casting thin slice and scanning electron microscope Observing the data and interpreting and making the relevant maps, the petrological characteristics, physical properties, lithology and physical properties of the Chang 8 reservoir in the study area are described in detail, and the services are divided for the favorable area.
