摘要
针对聚合物—交联聚合物驱油机理进行了分析 ,以数值模拟为手段 ,运用交联聚合物模拟软件进行模拟研究 ;以区块综合含水率、累计产油量和单井产油速度三项指标为依据 ,考查储层垂向非均质、平面非均质、高渗层厚度变化、注聚时机等几种影响因素对聚合物—交联聚合物驱油效果影响 ,在对比分析的基础上 ,阐明了各种因素的影响程度。研究表明 ,垂向非均质对聚合物驱油效果的影响最大 ,高渗层厚变化次之 ,注聚时机和平面非均质的影响比前两者要小。
An analysis is made of the mechanism for oil displacement with polymer-crosslinked polymer.A simulation study is made by using simulated software for crosslinked polymer.In light of such indicators as tract-based comprehensive water cut,cumulative oil offtake,and rate of oil production of individual wells,an examination is made of the influence of such factors as vertical heterogeneity,horizontal heterogeneity,thickness change of high permeability reservoir,and timing for polymer injection on the effects of oil displacement with polymer-crosslinked polymer.On the basis of a comparative analysis,a clarification is made of the dregree to which each factor has its influence.Research shows that vertical heterogeneity has the greatest influence,and thickness change of high permeability is second to it while timing for polymer injection and horizontal heterogeneity have less influence than the former two factors.
