摘　　要：多孔聚合物水泥材料防砂技术是一种全新的油层防砂技术，该项技术既能调节油层渗流流道横截面积和渗透率，又能加固油层井壁，防止油层岩石破坏。与传统防砂技术相比，能大大提高防砂效果和防砂周期，保证油井长期稳产。文中介绍了该防砂技术的基本原理和配方，多孔聚合物水泥材料由３ 种基本物质组成：有机收敛材料；可溶固相；不溶固相。多孔聚合物水泥材料防砂技术的主要优点是：可以根据需要改变配方调节渗流流道横截面尺寸和渗透率，以适应不同砂粒尺寸的出砂油层的防砂要求；固化的水泥石有足够的强度承受生产压差产生的挤压力，且热稳定性好，抗腐蚀能力强；聚合物水泥浆的流变性能很好地满足注入工艺要求。The new sand prevention technology using multi pore polymer cement material which is put forward in this paper is completely different from traditional ones.It can not only adjust flow area and permeability of production formations,but also reinforce the wellbore of production formations.This new technology will improve the effect of sand prevention and prolong the period of sand prevention greatly,so that the oil production will be stabilized for a long time.This paper briefly introduces the basic principle of the new technology and the research result of multi pore polymer cement material′s formulation mechanism.A basic formulation of the material and its technical advantages are also presented.
