Calculation Model of Rock Fracture Pressure Under Multifield Coupling Action
Abstract In this paper, we build an aggregative model to calculate the rock fracture pressure by the theory of double effective stress of porous medium; it takes into account such factors as the crustal stress field, chemical field, temperature field, the porosity of rock, seepage of drilling fluid, and so on. As the parameters of the model take different values, the model can predict the fracture pressure of different types of rocks under different geological conditions. Combined with the experimental data of field fracturing and the experimental results of three-axial compression of rock core with different water contents, the results show that the error of the this paper’s model is 4.39% compared with the measured value, which provides technical support for drilling engineering.
