Abstract
Crustal stresses play an important role in both exploration and development in the oil and gas industry. However, it is difficult to simulate crustal stress distributions accurately, because of the incompatibilities that exist among different software. Here, a series of algorithms is developed and integrated in the Petrel2ANSYS to carry out two-way conversions between the 3D attribute models that employ corner-point grids used in Petrel and the 3D finite-element grids used in ANSYS. Furthermore, a modified method of simulating stress characteristics and analyzing stress fields using the finite-element method and multiple finely resolved 3D models is proposed. Compared to the traditional finite-element simulation-based approach, which involves describing the heterogeneous within a rock body or sedimentary facies in detail and simulating the stress distribution, the single grid cell-based approach focuses on a greater degree on combining the rock mechanics described by 3D corner-point grid models with the finely resolved material characteristics of 3D finite-element models. Different models that use structured and unstructured grids are verified in Petrel2ANSYS to assess the feasibility. In addition, with minor modifications, platforms based on the present algorithms can be extended to other models to convert corner-point grids to the finite-element grids constructed by other software.
摘要
地应力是岩体在自然状态下存在的应力, 地应力场的分布对于油气田的勘探开发具有十分重要的意义。由于不同软件平台间数据存储和兼容性等问题, 数据的不连续性和不兼容性影响了地应力场分布状况模拟的准确性。通过 Petrel2ANSYS 数据平台相关算法的开发和集成, 实现了基于 Petrel 建模软件的三维角点网格属性模型和基于 ANSYS 有限元模拟软件的三维有限元模型的双向对接, 进一步提出并实现了基于复杂精细三维地质模型的地应力属性有限元模拟与分析。相比传统有限元地应力属性数值模拟方法, 创新性地提出了针对单一网格的岩石力学参数与有限元材料参数结合赋值的方法, 更精细地刻画出岩石内部和沉积相的非均质性, 进而准确模拟地应力场的分布状态。通过不同的数据测试了基于 Petrel2ANSYS 数据平台的对不同网格模型处理的有效性和准确性, 应用油田实例数 据实现了精细三维地质模型的地应力场有限元模拟, 准确度较高。此外, Petrel2ANSYS 作为一种通用性的数据算法, 进行稍微修改即可进一步兼容其他软件中角点网格与有限元网格的双向对接。
