摘要
文章研制了一种提高硅酸盐复合材料胶结体渗透性的高温增渗外加剂ZSJ。它是以复杂的天然有机 物GD为原料自行进行化学改性的产物,并辅助以无机材料MD,按20:7的重量比混配而成。它能使硅酸盐复合材 料凝固体的渗透率在0.09-1.5μm2内调节,并保持硅酸盐复合材料凝固体抗压强度维持在6～8 MPa内,该增渗剂 能够适用于油井温度小于100℃的油气井中,从而使硅酸盐复合材料能够用于高温条件下的油气井防砂。温度适 用范围宽,是一种新型的防砂增渗材料。
Through a lot of experiment, ZS permeability - increasing material was synthesized finally. It was a chemical modified product from a natural complicated organic matter GD. And adding inorganic matter MD, the ZSJ additive was developed to raise the permeable rate of silicate complex material. The permeable rate was from 0.09um2 to 1. 5um2 , compression strength kept in 6 to 8MPa. It is a new - type of the sand control permeability - increasing material.
