注浆堵水是水害治理最重要的方法之一。注浆堵水可分为地面(井上)注浆堵水和井下注浆堵水。井上下注浆堵水各有其长短。以前的注浆堵水都是井上、井下各自独立,互相之间没有结合起来。本文结合实际例子来说明井上下相结合的注浆堵水方法。井上下相结合的注浆堵水方法的目的是扬长避短,达到高效、快速、低成本、高质量、不影响生产等。 Grouting plugging is one of the most important ways to deal with water damage. Grouting water can be grouped into the ground (uphole) Grouting water and underground grouting water blocking. Up and down grouting water blocking their length. Before the grouting water plugging are upstairs, underground independently, not with each other. In this paper, a practical example is given to illustrate the method of grouting and plugging combined with vertical and horizontal. The purpose of grouting and water blocking combined with wellbore is to avoid weaknesses and achieve high efficiency, fast, low cost and high quality, without affecting production.
