Ochre feature prevention for fluid-prominent elements at horizontal filter wells, has cathode to aim backlash potential to horizontal filter pipe, slidegate valves, measuring instruments, coat pumps and pressure pipes

摘要

A titanium cathode arranged inside a filter pipe (10) aims a backlash potential to a horizontal filter pipe (9), slidegate valves (7) within a slidegate valve chamber (8), measuring instruments (6), coat pumps (3) and pressure pipes (4).
