摘　　要：针对下寺湾油田非均质油层参数在油藏范围内的分区性和差异性,利用油田非均匀井网分布对非均质油藏的控制及其储量分布的匹配关系,选择物性、原油性质及其延伸厚度相近的油层控制在一个区块储量计算单元内,从而有效地采用有效厚度下限的多参数标定确定区块含油面积及有效厚度。它可以明显有效地控制非均质油藏储量计算的精度,对确定油田的油气富集方向和开发潜力具有十分重要的意义。Considering differences of heterogeneous oil formation parameters in Xiashiwan oil field,and using the control of non-uniform well pattern distribution to non-uniform oil pool and matching relationship between its non-uniform well pattern distribution and reserves distribution,oil layers with similar physical properties,crude oil properties and extending thickness were controlled in one computing unit,thus oil area and effective thickness can be calibrated by multi-parameters method of lower limit effective thickness,which can efficiently control the calculation accuracy of non-uniform oil pool reserves and is meaningful for determination of hydrocarbon accumulation zone and development of great potential.
