Abstract: A method of geologic attributes modeling of oil reservoir based on sedimentary facies control is presented, and the digital model of reservoirs' sedimentary facies distribution can be established by fine geologic research results. On the basis of the digital model, interwell prediction for interaction between reservoir parameters and rock fluids can be realized. So the geologic modeling technique of oil reservoir controlled by sedimentary facies with Daqing Oilfield features has formed since it is used in software program. This modeling technique does not require any artificial interactivity compared with other methods, so it can greatly enhance the reliability and practicability of geologic model. Modeling practices for dozens of field blocks have showed that the modeling results not only can quantitatively reflect the understanding of geologic researchers, but also can make the successive remaining oil distribution study more accurate.
