鄂尔多斯盆地南部镇泾油田处于鄂尔多斯盆地西缘天环向斜的南段,石油资源潜力巨大,勘探开发潜力巨大,具有较好的勘探开发前景。依据录井描述、薄片鉴定、铸体图象分析及扫描电镜成果,对该地区储层特征进行研究。长8储层属于低孔、特低渗、中孔、细喉、分选中等型储层,主要存在成岩收缩缝和构造裂缝。
The Jingzhen Oilfield in the southern part of the Ordos Basin is located in the southern section of the Tianhuan syncline on the western margin of the Ordos Basin. It has great potential for oil resources and has great potential for exploration and development and has good exploration and development prospects. According to logging description, sheet identification, casting image analysis and SEM results, the reservoir characteristics in this area were studied. The Chang 8 reservoir belongs to low porosity, extra-low permeability, medium porosity, fine throat and medium-sized reservoirs, mainly diagenetic shrinkage cracks and structural fractures.
