潜山缝洞型碳酸盐岩储层油水流动规律研究——以塔里木油田英买32-7区块为例

Study on Flow Mechanism of Carbonate Buried Hill Fracture and Cave Reservoir

以塔里木油田英买32-7区块潜山缝洞型碳酸盐岩底水油藏储层为研究储层,充分认识储层储渗介质尺度及分布特征,对目标工区油藏的单井含水动态进行归类,分析典型井的油水流动规律与储层地质特征之间的关系。总结缝洞型碳酸盐岩储层油水流动规律的主控因素,并利用实际油井的动静态资料进行论证。

Yingmai 32-7 area in Tarim Oilfield is a buried hill fracture and cave reservoir with bottom water. This dissertation not only studied the medium＇ s dimension and distribution of this block,but also analysed the driving energy and its influence on oil-water flow mechanism. With the study on the combination of different permeable-storage medium and the correspondent seepage flow characteristics and the correspondent dynamic production characteristics of single wells,this paper classified the water production rate of single wells and analysed the relationship between typical wells＇ flow mechanism law and geological characteristics. Based on dynamic（ single well production performance） and static（ geological characteristics and reservoir permeability medium-scale features） analysis,this paper analysed how the reservoir＇s driving energy affected oil-water flow mechanism of this kind permeable-storage medium. All of this provides a new way to develop low yield and inefficient wells.
