Stress distribution analysis is crucial in oil and gas field development, especially in the unconventional oil and gas reservoir which affects the distribution of artificial fracture during hydraulic fracturing. Stress simulation based on finite element analysis is applied because of its flexibility and accuracy. While due to the incompatibility model grid format between software, geological modeling process cannot be effectively integrated with finite element analysis. Here, in face of the aforementioned problems, PCP2AFE software, several algorithms, is developed to fulfill the dual-transforming between corner grid model built by PETREL and finite element grid model generated by ANSYS. A series of models are imported to testify the validity and efficiency of the software, including both structured and unstructured grids with and without heterogeneous Furthermore, with the development of PCP2AFE software, stress simulation process can directly operate based on geological model without re-modeling in finite element analysis software. Also, the simulation results can be re-converted and linked to geological model based on corner point grid for subsequent analysis and as a result to effectively link PETREL and ANSYS software. Initially, the software is developed to perform models dual-transforming built by PETREL and ANSYS, slight modifications can be operated to make some more extensions in linking more software combinations which based on corner point grid and finite element grid. Meanwhile, models from previous are imported to perform the stress field distribution simulation. At last, several important conclusions and discussions for subsequent analysis are included.
