Abstract
The invention relates to a method capable of fast explaining and evaluating reservoir fluid properties. The logging drilling time and the total hydrocarbon and hydrocarbon components are collected and recorded through a drilling time instrument, a gas logging instrument, an integral logging instrument and other logging devices. The total hydrocarbon value Ct (percent) of the maximum effective value of a reservoir is obtained, and the total hydrocarbon average value, i.e. the basic value Cb (percent) of a cover layer of 5m to 20m above the reservoir is selected. The drilling time specific value RROP of the reservoir is calculated by the cover layer drilling time ROPn and the reservoir drilling time ROPs. The hydrocarbon contrast coefficient Kc is calculated by the total hydrocarbon value Ct (percent) and the basic value Cb (percent). RROP-Kc patterns are drawn through data points of an oil gas layer, a hydrocarbon-containing water layer and a dry layer after oil test verification according to region statistics, boundary lines AB and CD and three regions of the oil gas layer, the hydrocarbon-containing layer and the dry layer are determined according to the data statistics principle, regions of the data points in the RROP-Kc patterns are corresponding fluid explaining and evaluating results. The method is applied to more than two thousand wells in Jianghan oil regions, and the regional coincidence rate is higher than 85 percent. The method is applied in low-resistance oil gas layers, fractured oil gas layers and shale gas layers, particularly weak oil gas display and single component display layers.
