由生产引起的基质和断层渗透率变化数据的可靠性 ,对油气藏的规划和管理至关重要。油藏流体的流入和采出改变了孔隙压力 ,继而改变了 3D(三维 )有效应力状态。应力方向与油藏原始应力一致 ,随着应力变化 ,会引起油藏岩石变形和渗透率改变。本文通过非线性确定元素几何模型与不同流体流动状态模型相结合得出应力敏感性模拟 ,表明了渗透率动态变化和断层再生对油层特性的影响
The reliability of data on changes in matrix and fault permeability caused by production is crucial to the planning and management of the reservoir. The influx and recovery of reservoir fluids change the pore pressure, which in turn changes the 3D (three-dimensional) effective stress state. The stress direction is consistent with the original stress of the reservoir, and as the stress changes, the deformation and permeability of the reservoir rock will change. In this paper, the stress sensitivity simulation is obtained by nonlinearly determining the element geometry model and the different fluid flow model, which shows that the dynamic change of permeability and the influence of fault regeneration on reservoir properties
