吴仓堡区长9储层井网适应性评价

Well adaptability of Chang-9 reservoir in Wucangbao area

鄂尔多斯盆地吴起油田吴仓堡科技示范区延长组长9油藏属于特低孔、特低渗储层。研究区井网不完善,含油面积内未动用面积为23.13km^2。通过对研究区井网适应性分析可知:目前注采井网能够适应地质注水开发的需要,菱形反九点注采井网适合吴仓堡长9的储层特征。

The Chang-9 reservoir in Yanchang formation,Wucangbao area,Wuqi Oilfield,Ordos Basin is ultra-lowporosity and permeability reservoir. The well pattern in researching area needs to be improved,the unused area in oil-bearing area is23.13 km2. The analysis on the well adaptability of the area indicates that the injection-production well pattern meets the requirementsof geological water injection,the rhombus reverse nine-spot well pattern can be used for the reservoir described.
