摘要：

Parameters such as capillary pressure, relative permeability and resistivity index are important to describe reservoir properties and multiphase fluid flow characteristics in reservoirs. However, the relative permeability and capillary pressure could not be easily measured through experiments which are often time-consuming, demanding in instrument precision, and restricted by subjective conditions. The study discussed the correlation amongcapillary pressure, relative permeability and resistivity index based on the capillary tube model and Archie equation, and in turn built a transformation model among the three parameters. Besides, the accuracy of the transformation model was verified by rock-electrical property experiment. The results show that the relative permeability and the capillary pressure calculated with the transformation model are very close to that measured through in-situ experiments. The method proposed in this study can effectively calculate the relative permeability and capillary pressure with resistivity data, making it easier to figure out the two parameters. © 2019, OIL & GAS GEOLOGY Editorial Board.
