摘要
从国内外流动单元研究现状出发,结合研究区实际的岩心、地质、测井和生产动态资料,根据流动带指标和岩性-物性划分法划分流动单元.研究中遵循单井、剖面到平面的思路,开展了流动单元特征参数优选、取心井流动单元分析、非取心井的流动单元划分工作.运用动态资料验证流动单元划分的合理性,进行了流动单元剖面、平面特征研究及流动单元生产能力分析.研究表明,所选用的渗透率、孔隙度和流动层带指标IFZ3个参数可满足本区流动单元划分要求,研究区延9储层流动单元可划分为Ⅰ、Ⅱ、Ⅲ、Ⅳ类.
The flow units in the studied area were divided by means of flow zone index and lithology-physical property based on core and logging data.The parameter optimization of flow units,the flow unit analysis of cored wells and the flow unit division of no-cored wells were carried out according to the research thought of from single-well,profile to plane.The rationality of the flow unit division was verified by the dynamic data of the oilfield.The profile and plane characteristics and the oil production capability of the flow units were studied,and the results show that three parameters of permeability,porosity and flow zone index can meet the requirement of flow unit division in the studied area,and that the flow units of Yan-9 reservoir can be divided into four types.
