摘要
八面河油田面四区沙四段3砂组属于中-低渗透油藏,由于平面上储层物性、厚度、原油性质差异大,导致各区域采出程度差值大,平面矛盾突出。通过对该砂组上不同砂岩有效厚度内油井的开发特征进行分析,圈定现阶段能实现有效经济开发区域,对其剩余油分布进行研究,提出下步挖潜对策。
Sand Group 3 of Sha-4 Member in Mian 4 Area in Bamianhe Oilfield is the reservoir with medium-low permeability. Due to great differences in reservoir physical property, thickness and crude property on the plane, there is a big different value of recovery percent in every recovery region, leading to obvious plane contradiction. By analyzing development characteristics of oil wells within the effective thickness of different sandstones in Sand Group 3, this paper determines the regions which can be developed effectively at the present stage and studies their remaining oil distribution, followed by reprsentation of potential tapping measures.
