Abstract
The present invention relates to a multi-capillary force curve averaging method based on the overall virtual measurement of a plurality of samples. The method includes the following steps: 1, taking m types of rock samples, obtaining a capillary force-saturation curve, an apparent volume and a porosity of each sample; 2, inspecting the quality of the capillary force-saturation curve of each sample and preprocessing the end points of each curve; 3, calculating an averaged wet phase saturation corresponding to different capillary force values of the plurality of samples under the overall virtual measurement of a plurality of samples; and 4, denoting data points on a graph by using the wet phase saturation as the abscissa and capillary force as the ordinate, and finally connecting all data points smoothly to obtain the averaged capillary force curve. This method of the present invention is reliable in principle and easy to operate, can be directly operated on the capillary force curves, is also suitable for various types of samples with different physical properties in consideration of the influence of the numbers of reservoirs represented by samples, has a wide range of applications, and accurate and convenient calculation results, and is more consistent with actual working conditions.
