注水驱油过程中地层渗透各向异性时的流体压力分布

Stress Distribution of Fluid Osmosis at Isotropy through Petroleum Reservoir Bed during Injection-Production Process

研究高压注水时,地层渗透不均匀时的稳态和瞬态压力方程的弱解形式,并针对特定区块用有限元法计算分析高压注水时渗透不均匀特性引起的压力分布规律。

The weak integral form of pressure equation for nonuniform stratum osmosis was studied under the steady state and in- stantaneous state during high pressure water injection. The distribution regularity of stress due to the nonuniform osmosis characteristic in the process of high pressure water injection was analyzed with the finite element method using some given well area as examples.
