摘　　要：确定有效储层物性下限是储层评价和储量计算的核心,受多种因素影响,使得结果本身存在较大的随机性和不确定性。根据对国内外油气田评估的实践,统计分析多个国内外油气田的物性下限值,借鉴和总结多种方法,并对其适用条件进行认真分析,为确定储层物性下限提供了广泛的参考基础。利用试油试采资料对建立的储层物性下限标准进行验证,作为判断储层物性下限值的合理性提供一种依据,也为下一步勘探开发奠定可靠的地质基础。Determining petrophysical property low limits of the effective reservoir is the core element of reservoir evaluation and OOIP estimation. It is affected by many factors, making the results of a large inherent randomness and uncertainty. Based on the practice from the assessment of domestic and international oil and gas fields, A great many of low limit values and deterministic methods have been gained by statistics and analysis of multiple domestic and international oil and gas fields,besides,there is a careful research for the conditions of its application, which provide a wide range of reference base. The established standard of reservoir low limits have been confirmed by production and testing data, which provides a reasonable basis for determining the lower limit of the reservoir property and also lays a reliable geological foundation for the next exploration and development.
