| 摘 要： | 以提高油田采油速度为目的的人工压裂裂缝施工改造,对当前广泛应用于求取岩石力学参数的常规测井资料法提出了更高的要求。提出三维岩石力学参数场随机模拟预测的方法,即以已知有限的常规测井资料计算出来的岩石力学参数曲线作为硬数据输入,以已知地震属性数据体及泥页岩水化和岩石环境参数数据作为软数据约束,选择序贯高斯模拟方法,随机模拟得到动态规律变化的岩石力学参数的三维空间数据场,然后由岩石力学参数的三维空间数据场预测空间任一位置的岩石力学参数在井上的测井响应,并把该反映动态规律变化的测井响应按照油田勘探开发的要求输出成特定格式,供生产和工程上使用。该方法为当前岩石力学参数的求取开辟了一条全新的途径,对勘探开发上制定完善的钻井、完井与油气开发方案和技术措施提供重要的指导作用。 |

| Abstract: | Presently, the methods of conventional log data are widely used to calculate rock mechanics parameters and are strongly required by fissure working rebuilding of artificial fracturing with the purpose of increasing oil production rate in oil fields. The method of prediction on stochastical simulating 3D parameter field of rock mechanics is brought forward in this paper. Namely, rock mechanics parameters curve obtained by known and limited conventional log materials is took as inputs of hard data;and seismic attribute data body, hydrating of mud shale and rock environmental parameters data is took as constraint of soft data. By simulating stochastically through optimizing algorithm of Sequential Gauss Simulation,dynamical data field of rock mechanics parameter of three-dimensional space are gotten, then log response of rock mechanics parameters in position of any point in space is predicted. The special format of the log responses to refect the dynamic change rule is presented for use of producing and engineering according to demand of exploration and development. Sequentially, the method provides a significant guiding role to establish perfect drilling, well completion, oil gas development project and technical measures in exploration and development. |
