| Establishing a fault model with complex fault system has always been a problem for building geologic model. The 1st-3rd sandstone beds in the second member of the Shahejie Formation in the first district of the Shengtuo Oil Field is now at a high water-cut period in the study status of the development and geological difficulties,this paper establishes the structural model, the sedimentary microfacies model and the microfacies controlled property model using facies-controlled modeling technology with the facies-controlled modeling technology,studies the physical properties of reservoir space characteristics through the results,and finds out the distribution of reservoir properties of non-homogeneous. This is significant to further study distribution of remaining oil,the next step to develop reservoir and enhance oil recovery.Several achievements have been obtained as follows: (1)The techniques of the building geologic model in complicate fault block oil reservoil establishes the structural model, the sedimentary microfacies model and the microfacies controlled property model,the difficulty is how to build fault model, application of digital methods of surface structure maps to build it; (2)Establishing the sedimentary microfacies model with approach of deterministic modeling; establishing reservoir parameters three-dimensional model and the mean model of reservoir with approach of stochastic simulation methods;(3)The reservoirs and their parameter distribution are Consistency under the micro-facies modeling, which win the study area reservoir description of the property for more accurate and reasonable;(4)Verifying and testing the model shows the model more consistent with the actual geological conditions;(5) Based on research result we put forward for further tapping the potential sand sets 1-3 Sands reservoir: increasing the development efforts of non-main oil layer and using new technologies and new techniques fully to tap the potential of remaining oil within the main layers.
