Research status and outlook for methods of determining petrophysical property cutoffs
摘要
Abstract
Petrophysical property cutoffs are important parameters to identify reservoirs and their effective thickness in calcu-lating reserves. Based on literature review and case studies, the methods for petrophysical property cutoffs and development trends are explored. Some conclusions can be drawn:1) all methods can be divided into core analysis method and oil test method based on the characteristics of the methods and the data used;2) core analysis method can take some thresholds as petrophysical property cutoffs through statistical analysis of parameters such as porosity, permeability and so on. Its results are aggressive and the method is suitable to exploration stages where no enough test data is present;3 ) oil test method can get petrophysical property cutoffs through statistical analysis on the relation of production capacity with some parameters such as oil-bearing occurrence, porosity, permeability and so on. Its results are conservative and the method applies to develop-ment stage. In addition, it is good to make dynamic adjustment of the cutoffs in development stages with the combination of core analysis method and oil test method;4) it is necessary to pay more attention to the impacts of some issues such as reser-voir heterogeneity, production test and so on.关键词
