摘要: 在特低渗透油水同层油藏地质特征分析的基础上,利用相对渗透率资料计算出不同渗透率油层含水率与含水饱和度关系式,并在3口密闭取心井岩心分析和试油(采)资料校正下,得到油藏条件下不同渗透率油层含水率与含水饱和度关系式,建立特低渗透油水同层油藏油层初期含水率解释图版。经葡西油田古109试验区11口井单层射孔资料验证,图版解释符合率为82%。该图版为油水同层油藏开发中确定开发井完井下限和界定开发井射孔层位提供了有效依据。

Abstract: Based on the analysis of the geological characteristics of mixed oil-water reservoirs with extremely low permeability, the relation between water cut and water saturation for various oil layers with different permeability is formulated by the relative permeability data. Through core analysis of three sealed coring wells and correction of oil testing (production) data, the relation between water cut and water saturation of oil layers with different permeability under reservoir conditions is modified and the interpretation chart of initial water cut of mixed oil-water reservoirs with extremely low permeability is established. After verification of single layer perforation data of eleven wells in Gu 109 pilot block in Puxi Oilfield, the coincidence rate of chart interpretation reaches 82%. The chart has provided an effective foundation for the determination of completion interval and perforation horizon of development well during the development of oil-water mixed reservoirs.

Key words: extremely low permeability, mixed oil-water reservoir, initial water cut, relative permeability, interpretation chart
