研究了粘度比、界面相互作用、加工条件和共混比例等因素对pp eoc体系分散形态和性能的影响，发现粘度比小和加工过程中剪切强度大有利于弹性体在基体中分散均匀细化；粘度比小、界面相互作用强、弹性体本身的流动性好及成型时受到的剪切应力大，使弹性体相易变形，沿流动方向取向呈纤，阐明了各因素对形态影响的作用机制，这对pp eoc共混物的形态控制具有重要的指导作用。 - The theoretical study of the recovery percent vs . water cut of thin and bottom water reservoir in luliang oilfield is based on developing its geologic and flow models , obtaining oil - thickness ratio , oil - water viscosity ratio , relative permeability curve parameter and chart of effect of bottom water toning , etc . , on water - yielding pattern of the reservoir
