摘要

In order to correctly classify and evaluate the low-permeability reservoirs, the paper discusses the classification significance of cumulative probability curve. For the reservoirs with different properties, the properties such as the number of the line segments, the location of intersection points and the slope of line segments are also different in the cumulative probability curve. Based on the optimization of the evaluation parameters of low-permeability reservoirs in different development blocks of Chaoyanggou Oilfield, gray correlation analysis is used to determine the weight coefficient of each evaluation parameter, and the evaluation index has been calculated by comprehensive evaluation method, and furthermore, the cumulative probability curve diagram is drawn for index evaluation. Finally the classification of the low-permeability reservoirs in Chaoyanggou Oilfield has been conducted by the above diagram.
