Calculation Method of Bioclastic Limestone Reservoir Space Using Log Data in theMiddle East Area × District
摘要
Abstract
The main reservoir of H oilfield in the Middle East area × district is bioclastic limestone, whose reservoir space types are complex.There are primary pores such as intergranular pores and intrafossil pores accompanied by secondary pores such as dissolution pores and mouldic pores.The secondary pores are strongly linked to reservoir capacity and permeability.We confirmed the type of reservoir space based on thin sections and logging analysis.Then Gaussian fitting algorithm is used to dispose image logging porosity spectral and the cutoff value and proportion of primary and secondary porosity are obtained.Furthermore, we analyze the relationship of proportion and acoustic, density, neutron and NMR, set up a calculation model of secondary pores.Research results show that, with classifying reservoir space and defining the cutoff and proportion of primary and secondary pores, which is used to scaling conventional logging responses, we can set up a method to calculate secondary pores proportion based on conventional logging.Results of both method are similar, which indicates that the method to calculate secondary pores proportion is effectively in bioclastic limestone, adding new thought and method to quantitative calculation of reservoir space.关键词
