由于地下水具有腐蚀性和结垢性,由于腐蚀将破坏井的结构强度、完整性,扩大过滤器间隙,结垢(包括腐蚀产生的次生沉淀结垢)将堵塞过滤器、填砾和附近的含水层,从而影响了供水管井的正常运转和使用寿命。在一些工业水平比较高的国家,为了充分发挥油井、水井的经济效益,对管井的腐蚀性、结垢性的机理研究和防治比较重视,有些经验可供借鉴。
Because of the corrosive and fouling of groundwater, corrosion will destroy the structural strength and integrity of the well, and expand the filter gap. Fouling (including secondary sedimentation due to corrosion) will clog the filter, fill the gravel and nearby. The aquifer affects the normal operation and service life of the water supply pipe well. In countries with relatively high industrial levels, in order to give full play to the economic benefits of oil wells and wells, more attention is paid to the study of mechanism and prevention and control of the corrosion and fouling of tube wells, and some experiences can be used for reference.
