| Abstract: | The quantitative classification and evaluation of low permeability reservoir are studied with Chang 3 and Chang 4 5 of triassic formation in Baibao oil field as examples. Based on the study on key wells and the rational choice of classification parameters, the function of reservoir quantitative classification and evaluation is established by combining Q-model cluster analysis with Bayes discrimination. This discrimination function is used in quantitative classification and evaluation of interested interval of non-coring wels in the study area. The vertical and horizontal distribution characteristics of reservoir are also studied, and the pay reservoir area is confirmed. The results show that the application of the quantitative classification and evaluation is practical and with wide coverage. |
