实践表明,常常由于围填砾料不到位影响成井质量,缩短水井寿命。如今,河北省满城钻井公司生产的一种新型水井滤水器——贴砾滤水管,有效地解决围填砾料不到位的问题。 贴砾滤水管是用合成树脂将一定粒径石英砂粘到钢制衬管上制成的,具有透水性好,滤砂可靠、耐热、耐腐蚀、降低成井造价等优点。 Practice shows that, often due to less than fill gravel material into the well of quality, shorten the life of wells. Now, a new type of well water filter produced by Mancheng Drilling Company in Hebei Province - the gravel filter pipe, effectively solves the problem that the gravel material is not in place. Sticky gravel filter pipe is a synthetic resin will be a certain size of quartz sand glued to the steel liner made of, with good water permeability, filter sand, reliable, heat-resistant, corrosion-resistant, reducing the cost of wells and so on.
