摘要

本文介绍了一种水玻璃单液法高强度的调剖剂,其特点是胶凝时间在3~26小时内可以调节,适用于70~100℃温度的地层,封堵强度高,堵塞率高。该堵剂属无机堵剂,配制简单,便于施工,无毒无臭,是一种新型中高温堵剂。

Abstract

This paper introduces a kind of sodium silicate single-fluid water-control agent,which advantages are that the gelation time is agjustable between 3 to 26 hours,that it is suitable to the oil reservoir with the temperature of 70 to 100℃,and the plugging strength as well as succes rate are hing.It is a inorganic water-control agent,simple to compound,easy to operate,nontoxic and stinking,is a kind of new type medium-high temperature water-control agent.
