贴砾滤水管是一种新型水井过滤器,它是用合成树脂将一定粒度的石英砂粘到钢制衬管上制成的,具有良好的透水、滤砂性能,已大量用于水井建造工程。 涌砂是影响水井寿命和水质的重要原因。一般成井工艺多釆用缠丝滤水管,有些由于填砾不当,造成涌砂以致报废。为探索修复涌砂井,我们使用贴砾滤水管进行了新的尝试,取得了良好的效果。
The gravel filter pipe is a new type of water well filter, which is made of synthetic resin to bind a certain size of quartz sand to a steel liner. It has good permeability and sand filtration performance and has been widely used in well construction projects. . Sand influx is an important factor affecting the well’s life and water quality. The general well-manufacturing technology often uses silk-wrapped water filter pipes, and some of them are due to improper gravel packing, which causes sand intrusion. In order to explore the repair of the gushing wells, we used a pebble filter pipe to make new attempts and achieved good results.
