摘要：

通过对储量评估中油气田、区块、开发单元和计算单元等四级单元应用现状的研究,提出了建立四级单元对应关系的基本原则。在此基础上深入分析了计算单元划分方法,明确提出应从纵向和平面两个角度对油气水系统进行适当合并或细划,以确保储量计算结果的精度:纵向上主要考虑岩性组合、流体性质、油气藏类型、储层分布范围等;平面上主要考虑油气藏规模、油气藏复杂程度及其与油气水关系的配置情况等。

Abstract:

Based on the research of the application of four-order units(i.e.oil/gas field,block,development unit,and calculation unit) in reserve estimate,basic principles are proposed for establishing the corresponding relationship of the four-order unit.Upon this relationship,the paper analyses in detail the classification of calculation units,and suggests that in order to maintain the accuracy of reserve calculation,the oil-gas-water systems shall be incorporated or subdivided vertically and horizontally.Vertically,the main concerns shall be the lithologic association,fluid property,oil/gas reservoir type,reservoir distribution,etc.;while horizontally,factors such as oil/gas reservoir scale,complication,and configuration of oil,gas,and water layers,shall be taken into consideration.

Key words: reserve unit, corresponding relationship, oil-gas-water system, reserve estimation
