摘要: 低孔低渗油气储层存在巨大的开发潜力,而物性下限是评价低孔低渗储层的一个重要参数。针对低孔低渗储层的物性下限,国内外专家学者进行过诸多研究,但缺乏方法对比分析及适用性研究。鉴于此,在阅读大量国内外文献的基础上,概述了储层物性下限这一概念的来源及定义;结合实例归纳了低孔低渗储层物性下限的影响因素;总结了3类确定方法:以岩芯资料为基础的方法、岩芯与试油资料相结合的方法、以测井资料为基础的方法,阐述了每种方法的适用性,建议根据研究区地质背景、资料占有情况选择适当方法,并且要多种方法相互结合验证。在此基础上,分析了储层物性下限研究的发展趋势,以期对低孔低渗储层物性下限更进一步的研究提供支持。

Abstract: Low porosity and low permeability oil and gas reservoir is of huge potential. Cutoff plays a very important role in the process of reservoir evaluation. The domestic and overseas scholars have done a lot of researches, but there still lack method comparison and applicability research. Therefore, after literature review, this paper elaborates the origin and definition of cutoff, and summarizes the influencing factors with examples. On that basis, we summarize three kinds of methods of cutoff determination:methods based on core data, methods based on core and test data, and methods based on logging data. The applicability of each method is illustrated. We suggestthat the methods be selected according to geological backgrounds and data available, and cutoff determination results be tested and supported with different methods. Based on the above research, we analyze the development trends of researches on cutoff pay hoping to lay a foundation for further researches.

Key words: low porosity and low permeability, cutoff, factors, method, applicability
