摘要
Aiming at the geological characteristics of Nanpu oilfield, geological model was established by professional geological modeling software Petrel and was transformed into finite element model by using self-edited interfacial program. The finite element model was inputted into the finite element software Abaqus and finite element numerical simulation was conducted. Finally, the three-dimensional stress field distribution of simulated domain was obtained. The procedure and method of computing complex fault block in-situ stress field is established by combining geological modeling software and finite element software.
