Stochastic Simulation Study on Development of Reservoir Fracture -Taking the third segment of Wumishan formation in Renqiu buried hill as an example

摘要

The mechanical properties of reservoir rock are more complicated and the various mechanical parameters of rock itself have a strong uncertainty. The mechanics characteristics of rock in the study area can not be well determined if only a limited number of experimental datas. Therefore, in this paper, the third segment of Wumishan formation in Renqiu oilfield is taken as an example, the probabilistic models are used to describe the uncertainty of the rock mechanical parameters based on ANSYS, in which predict and analyze the degree of fracture development at key wells in the target layer of the study area.
