摘　　要：针对G油田XX井区非均质油藏参数变化难于适应剩余油分布富集描述的问题,利用单井控制计算储量,将油层有效厚度、物性和原油性质接近的油砂层控制在一个单井计算单元内,考虑非均质油砂层参数平面和纵向上的差异及其油气采出量,计算出了各油砂层单井控制地质储量、技术可采储量和剩余可采储量。利用单井控制可采储量,分析单井剩余可采储量和剩余油分布图表,阐明了剩余油平面和剖面分布富集井区、层位及其相应位置和形态,提供了目的层段剩余油挖潜规模、范围及其具体井位和富集量,为剩余油挖潜和高效开发指明了方向。Aiming at the problem that it is difficult to adapt the varying parameters of XX block in G oilfield to the heterogeneous reservoirs conditions of this area, single well controlled reserves calculation has been applied to include oil-sand layers with similar effective reservoir thickness, physical properties and oil feature in a single well calculation unit. Horizontal and vertical differences of heterogeneous oil-sand parameters as well as the oil recovery have also been taken into account. Ultimately the single well controlled geological reserves, technically recoverable reserves and remaining recoverable reserves of each oil-sand layer have been obtained. By using single-well controlled recoverable reserves to analyze distribution diagrams of single-well remaining recoverable reserves and remaining oil, horizontal and vertical residual oil enrichment regions, layers and their forms are given, in addition, the residual oil exploration scale, extent, location, and enrichment amount of the target layers have been provided, making it evident the way for the further exploration of residual oil and efficiently development of the oilfield.
