密井网条件下不同流动单元剩余油分布研究——以延长油田双河区块为例
|
摘要
延长油田双河区块已进入开发中后期阶段,需要在密井网条件下重新认识研究区的剩余油分布特征,从而指导挖潜。通过精细地层对比细分小层,总结了6种井间砂体连通模式及渗流屏障类型,为定量研究流动单元提供依据。借助岩心、测井资料,优选了与储层厚度、物性及含油饱和度等相关的宏观、微观参数,应用聚类分析的方法,将储层划分为Ⅰ类、Ⅱ类、Ⅲ类3类流动单元。在流动单元三维地质模型基础上进行油藏数值模拟,研究了流动单元中剩余油分布的特征,并与实际开发特征进行对比,明确了剩余油分布情况,为下一步制订具体的开发调整方案提供了依据。
Shuanghe block has entered the middle and late stages of development,the distribution characteristics of remaining oil in the infill well networks need to be known again in the studying area,so as to guide the tapping the potential of oil production. Through the comparison of the fine stratigraphic subdivision,the six connecting modes and seepage barrier for sand bodies have been summarized,and provided a basis for studying the flow units quantitatively. By means of the core and logging data,the macroscopic and microscopic parameters that related to reservoir thickness,physical properties and oil saturation have been optimized,and used the cluster analysis method to divide the reservoirs into three categories of flow units. Numerical simulation of reservoir flow unit was conducted on the basis of three-dimensional geological model to analyze the features of remaining oil distribution in the typeⅠ,Ⅱ and Ⅲ flow units,and compared with the actual development characteristics,finally specified the distribution of the remaining oil,which can provide the basis for making specific development plan in the future.
