摘要
以交联聚合物溶液 (LPS)体系深部调剖室内和矿场试验结果为基础 ,建立了一个交联聚合物线团深部调剖数学模型 ,其中分别计算了在岩石表面的吸附和在孔隙介质中的机械滞留对渗透率降低的贡献 ,模型中考虑了线速度和压力梯度对封堵强度和封堵位置的作用。把该模型结合到黑油模型中 ,可以进行LPS深部调剖的室内岩心驱拟合和矿场应用效果预测。
Based on the results of laboratory and field of LPS deep profile control, a LPS deep profile control mathematical model is established .It computes both contributions to the permeability reduction by adsorption on rock surfaces and by machanical entrapment at porous matrices separately.This model describes effects of linear velocity and pressure gradient on the shutoff distance. If this model will be incorporated into the black-oil model,it can match core flooding result of LPS deep profile control,it also can predict field effect.
