Simulation of Hydraulic Fracture Responses Based on a Magnetotelluric Monitoring Method
-
摘要:
常规电磁水力压裂监测方法测试范围受限于仪器源距，难以满足超深低渗储层压裂对监测纵向深度的要求。为此，在大地电磁场监测理论的基础上，结合有限元算法，基于油田生产实际，建立了直井水力压裂大地电磁地面监测正演模型，采用过渡边界条件模拟了裂缝尺寸和方位对大地电磁监测结果的影响。模拟显示，阻抗偏移能以不同方式反映裂缝参数的变化，对裂缝方位角有较好的区分度。研究结果表明，大地电磁监测方法是一种行之有效的压裂裂缝监测手段，研究结果可以为后续相关研究提供借鉴。
Abstract:The test scale of conventional electromagnetic hydraulic fracture monitoring methods is limited by the source distance of the instrument, and it is difficult to meet the requirements of longitudinal depth for monitoring in ultra-deep and low-permeability reservoirs. Therefore, based on the magnetotelluric monitoring theory and finite element algorithm, the forward model of vertical well hydraulic fracturing was established according to the actual production of oilfields. By using transitional boundary conditions, the influence of fracture shape and orientation parameter changes on magnetotelluric ground observation was simulated. The simulation results show that the impedance offset can reflect the change in fracture parameters in different ways, and it has an good degree of discrimination on the azimuth angles. The research shows that the magnetotelluric monitoring method is an effective means to monitor fracturing fractures. The research results can provide a reference for the subsequent related researches.
