Air lift reverse circulation drilling rig

Air-lift reverse circulation drilling technology is often used in geothermal well drilling, but there are many problems along with drilling depth increasing, such as double-wall drill pipe leaking, air-water mixer blo. [pdf]

Reverse circulation water well drilling rig construction technology

DTFR has also been utilized in applications found in the mining industry such as dewatering wells, construction of vent shafts, paste holes, and injection and disposal wells. In the civil construction industry, it has achieved notoriety for its ability to advance large-diameter foundation boring in environmentally. . See Diagrams A, B, and C. The borehole is continuously filled with drilling fluid and a fluid column is created and maintained between the. . DTFR matches up positively with basic requirements needed to construct large-diameter municipal and commercial wells in many regions across the country. DTFR is also. . Klint Gingerich and his brother, Korwin, are co-owners of Gingerich Well and Pump Service, a family-owned and operated business. . Tooling up for DTFR requires a substantial investment to begin: a suitable rig, in-hole tools, shale shakers, and a compressor. And the economics associated with DTFR technique only begin. RC technology aids in installing groundwater monitoring wells and collecting soil samples for contamination studies. Its precision helps track pollutants and design remediation strategies. In mining operations, RC drills create blast holes for controlled explosions. [pdf]

Drilling rig mud circulation system

This is the tank from which drilling fluid is pumped downhole and to which drilling fluid returns from the hole is received. The route taken by the drilling fluid when circulating is called the active (circulating) system. At the start of circulation, the Mud Pumps are lined up on the Active Tank, and drilling fluid is pumped to the. . These are used for storing fluids according to requirements. Reserve mud is usually prepared or stored in these tanks or different fluids in preparation for. . The Sand Traps are usually positioned below the shale shakers and act as settling pits for the drilling fluid after passing through the shale shakers. The. . These tanks are more minor than active and reserve tanks. They are used for preparing “slugs” (high-density mud that is pumped into the drill string before tripping out of the hole) and pills to address particular situations (e.g. an LCM pill to control formation losses, a unique mix to improve drilling mud properties, etc.). . The Trip Tank is a tall, narrow tank located near the flow line and used for accurately monitoring drill pipe displacement volumes while tripping pipe in or out of the hole. Active drilling mud from the Trip Tank is circulated across the hole, and valves in the flow line near the Bell Nipple are realigned to send the fluid returns back to the Trip . [pdf]
