本文综合考虑了射孔孔眼状态、各向异性储层伤害、以及不同边界条件等因素，建立了射孔井的油藏模型和非稳定渗流数学模型。应用边界元数模直接解法和区域分割技术，得到了随射孔孔眼和储层伤害变化时，孔眼附近储层不稳定渗流规律、生产动态和不稳定压力变化特征。对于更好地解决开发井网布置、射孔参数优化、增产措施设计和不稳定试井方法改进等生产问题有实际指导作用。边界元方法在油藏数值模拟领域有广阔的应用前景。
In this paper, the reservoir model of perforation well and the unsteady seepage mathematical model are established by considering the perforation state, anisotropic reservoir damage and different boundary conditions. By using the solution of boundary element mode direct method and region segmentation, the unstable seepage law, the production dynamic and the unstable pressure change of the reservoir near the perforation are obtained with the change of perforation and reservoir damage. It has practical guidance for better solving production problems such as well pattern deployment, perforation parameter optimization, design of stimulation measures and improvement of unstable well test methods. Boundary element method has broad application prospects in reservoir numerical simulation.
