河南油田稠油油藏水淹规律研究

从河南油田稠油油藏地质特征和蒸汽吞吐开采特点出发,利用岩心分析资料和开发取心检验井数据,应用油藏工程、数理统计、矿场测井分析和岩心刻度测井的方法,建立了高精度的储层岩性、物性测井解释模型。研究了稠油水淹层的特征,确定了定性和定量判断稠油水淹规律的方法,指出了目前稠油剩余油在纵向、平面上的分布规律,为油田后期编制开发方案、增产挖潜提供地质依据。

Study on waterflooding regularity of heavy oil reservoir in Henan oilfield

Starting from the geological characteristics of heavy oil reservoir and production feature of steam stimulation, based on the core analysis and testing data of development core inspection well,with the methods of reservoir engi- neering,mathematic statistic,field well logging analysis and core calibration logging,the logging interpretation pattern of reservoir lithology and physical property with high accuracy is established.After studying the water- flooding characteristic of heavy oil,the qualitative and quantitative method to confirm the regularity is deter- mined,and its distribution regularity on the vertical and horizontal direction at present is summarized,which pro- vides geological basis for field development plan,stimula- tion and tapping potential at later stage of oilfield produc- tion.
