低孔低渗储层物性下限确定方法及其适用性
Methods of Cutoff Determination and Applicability Analysis in Low Porosity and Low Permeability Reservoir
摘要
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.关键词
