| 摘 要： | 在地下流体的开采过程中,随着地下流体的不断采出,必然造成孔隙流体压力的逐渐降低,由此导致储层岩石骨架的有效应力增大,地层产生变形或压实,甚至造成地表沉陷。针对饱和土固结问题,利用可变形多孔介质中流体渗流的流固耦合有限元数值模型,对该问题进行了数值模拟。同时,对油井开采过程进行了模拟。

| Abstract: | The effective stress in the rock matrix of a reservoir increases as a result of the decline in pore fluid pressure with the continuous withdrawal of subsurface fluids.Under such conditions,more load is transferred to the rock matrix,and thus the rock is compacted or deformed,which can sometimes produce ground subsidence.The soil consolidation can be simulated by using a finite element numerical model of fluid-solid coupling of fluid seepage in a deformable porous medium.In addition,the production process of oil wells is also simulated. |

| Keywords: | fluid-solid coupling soil consolidation finite element method numerical simulation |
