摘要:
为解决致密岩性油气藏储层非均质强渗流特征复杂,剩余油富集规律不清的问题,以靖边油田为例,运用Amaefule提出的流动分层指标法,建立流动单元分类标准图版,进而确定出流动单元类型。通过岩心归位建立孔、渗透率的解释模型,求取各井点FZI值,划分平面流动单元,采用单井劈分法研究剩余油的分布规律,分析流动单元类型与剩余油分布响应关系。结果表明致密岩性储层的渗流特征体现流动单元类型与剩余油的响应关系,流动单元类型与井网完善程度对剩余油分布均有明显控制作用,井网完善程度较低时,流动单元指数越高,单井的剩余储量越大,井网完善程度较高时,在流动单元的过渡区剩余油的储量较大。利用FZI流动分层指标法研究致密岩性储层的渗流特征,可以更加有效地指导开发剩余油。
Abstract:
Abstract:For tight lithologic reservoir developped in Ordos Basin, the flow process of hydrocarbon is characterized by heterogeneity seepage, which results in that the distribution of remaining oil is extrermly complex. Taking Jingbian oil field as an example, this study adopts Flow Zone Index(FZI)method to establish the Classifing Criterion for flow unit, and to identify the types of flow unit. Using the porosity and permeability interpretation models, the FZI valus of production wells are calculated, and the flow units are divided. Using Single Well Splitting method, the relationship between flow units and the distributions of remaining oil are discussed, and the distribution of remaining oil is forcasted. The research results show that, well patterns and types of flow units have direct effects on the distribution remaining oil. For areas with low perfect degree of well network, the flow unit index is high, and the remaining oil mainly distributes in some specified wells. For areas with high perfect degree of well network, the flow unit index is low, and the remaining oil mainly distributes in transition zones. It is more effective to develop the remaining oil by studying the percolation characteristics of tight lithologic reservoir using FZI method.
