Abstract：Taking Tahe fractured-cavity carbonate reservoirs as the prototype,a new technology of the two step modeling controlled by karst facies of multi-scale fractured-cavity reservoir is developed. It is a two step modeling method under the control of the ancient karst development mode: the first step is the establishment of four discrete distribution models of a single type of reservoir, namely, using the seismic identification and description of the results, to establish a large cave discrete distribution model and a large-scale fracture discrete distribution model. With the karst facies constraints, based on the probability of caves and fractures to be developed between the body and the wells, and the multi-attribute co-simulation, the dissolved pores stochastic model and the small scale fractures discrete model are built. In the second step the parity condition assignment algorithm is used, to integrate the four single types of models into a multi-scale discrete fractured-cavity reservoir 3D distribution model. The quantitative model in 3D space to characterize the distribution feature of the fractured-cavity reservoir may serve as a solid geological foundation for the oilfield development.
