鄂尔多斯盆地定边油田长2低渗砂岩储层特征及评价OA北大核心CSCDCSTPCD
鄂尔多斯盆地定边油田长2储层为三角洲平原分流河道沉积的中—细粒长石砂岩,平均孔隙度为16.36％,平均渗透率为9.58×10-3μm2,属中孔、中—低渗储层.根据压汞曲线、铸体薄片等分析资料及试采、录井等测试结果,对长2储层特征进行研究和综合评价认为:长2储层孔隙类型主要有原生孔隙和次生孔隙,后者发育的长石溶孔对储层物性改善起到了积极作用；成岩作用类型主要为压实作用、胶结作用和溶蚀作用,前两者对储层物性破坏严重,而溶蚀作用扩大了储集空间,改善储层…查看全部>>
The Chang 2 reservoir in the Dingbian oilfield of Ordos Basin contains medium - fine feldspathic sandstone in delta plain distributary channel deposit, with average porosity of 16.36% and average permeability of 9.58 × 10~3μm , belonging to medium porosity and mid - low permeability reservoir. The Chang 2 reservoir has been studied and evaluated based on analytical data of intrusive mercury curve and casting thin section as well as the results of production …查看全部>>
