鄂尔多斯盆地陇东地区长8段储层特征与储层四性关系研究

Chang 8 section reservoir characteristics and four properties relationship of Longdong region in Ordos basin

鄂尔多斯盆地三叠系长8储层在陇东地区是重要的勘探目的层之一,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。根据该地区长8区域地质背景,通过对该区数百口井的测井、录井、岩心和试油等资料的收集、整理、校正、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,对研究区低渗储层的特征及四性关系作了较为详细的剖析。

Triassic Chang 8 reservoir in Longdong region of Ordos basin is one of the most important exploration target layer, reservoir physical property is poor, diagenesis is complex, resulting in reservoir with strong heterogeneity, so the reservoir characteristic research work has become one of the research focuses. According to the regional geological background of the study area, hundreds of well logging, logging, core and oil testing data have been collected, collated, corrected, analyzed. Combined with the casting thin sections and scanning electron microscopy and other experimental observation, relevant maps in the study area is interpreted and made, a more detailed analysis has been made on low permeability characteristics and four properties relations.
