拖市低渗透油藏数值模拟研究

建立了拖Ⅱ断鼻南断块地质模型．在此基础上用自行研制的动态地质模型低渗非达西渗流的油藏数值模拟软件进行了模拟研究，得到了如下认识：拖Ⅱ断鼻南断块地质模型是动态变化的；拖市低渗油藏渗流表现为低渗非达西渗流；以注水井连线为中心含油饱和度低。向两侧含油饱和度高；注入水沿裂缝前进，裂缝附近含油饱和度低；剩余油饱和度大致呈连续片状分布。提出了合理的开发调整方案。

Numerical Simulation in Tuoshi Low Permeability Reservoir

A geologic model for the south fault block of Tuo 11 fault nose is established. On the basis stated, a simulation study is performed by using a numerical reservoir simulating software of non-Darcy perculation of a self-developed dynamic geologic model. The following conclusion is achieved the geologic model for the south fault block of Tuo 11 fault nose is a dynamic one, perculation in Tuo 11 low permeability reservoir is a low permeable non-Darcy flow with low oil saturation centering at injector line and with high oil saturation at both sides, injected water advances along fractures, oil saturation is low around fractures, remaining oil saturation is distributed in continuous sheet approximately. A rational development-adjustment scheme is proposed.
