Study on Physical Property Lower Limit of Effective Reservoir of Deep Layer in Qingshui-Yuanyang Area

Abstract:

Synthetically using the empirical statistic method, porosity—permeability intersection method minimum flow pore throat radius method and oil test method. We can seek for the physical property lower limit of different depth of deep reservoirs of Yuan Yang Gou. According to liner regression, we achieved the functional equation which shows functional relationship between physical property lower limit and depth. At the same time, we also talk about the characteristics of different methods and the control factors of physical property lower limit The results show that although the methods have advantages and disadvantages, we should use these methods in a synthetically way. However, the porosity lower limit of the study area mainly is controlled by reservoirs which is based on primary pore and mainly affected by the depth, it also presents a good liner relationship with the logarithm of depth of burial .Permeability lower limit is mainly affected by reservoirs that is based on secondary pore Permeability lower limit shows a exponential relationship with depth of burial too, but its relative relevance is bad.
