Hydrogeological and water well drilling are important parts of exploration engineering. With the increasing demand of underground water resources and requirement intensification of ecology and environment protection, the hydrogeological and water well drilling engineering become more important. In the well completion process, corrosion and scaling of the filter are often encountered, which directly affect the wellbore influent amount and pumping effect, and even lead to the filter being scrapped and water well abandoned. Prof. Третьяк А.Я., who works in National University of Technology in Southern Russia, and some others have invented a new automatic scale-handling water filter and resolved the filter corrosion and scaling in the drilling process.
