| Optimization and Application of Unit Volume Method Based on Petrel Three-dimensional Geologic Modeling: A Case Study of Geothermal Resource Evaluation in Shixi Oil Field, Junggar Basin |
| The unit volume method is a commonly used method for geothermal resource evaluation, which involves inscribing the parameters on a two-dimensional plane and accumulating the total amount after calculating the parameters of each unit. This reduces the calculation accuracy and is cumbersome for the large and irregular study area. Therefore, in this study, based on the rich geological data of the Shixi Oilfield, we use the ground temperature parameter to simulate the porosity, establish the Petrel property model (i.e., ground temperature field model) to optimize the unit volume method, realize the fine inscription of the relevant parameters on the three-dimensional plane, and automatically derive the product of the temperature difference and volume, which can be used for subsequent calculations. The optimized unit volume method calculates the geothermal resources in the study area at a depth of 10 km to be 2 521.58×1018 J, which is 12.57% lower than that calculated by the thermal storage method based on the COMSOL Multiphysics model. The optimized unit volume method highlights the inhomogeneity of the temperature of the thermal storage and the accuracy of the volume estimation, and improves the computational efficiency and computational accuracy. Based on the geothermal model, the distribution characteristics and main controlling factors of the present-day geothermal field are analyzed, and wells A and B and the surrounding areas in the study area are favorable zones. This study clarifies the potential and distribution patterns of geothermal resources in the Shixi Oilfield and provides a scientific basis for the rational utilization of geothermal resources in the study area. |
