Oil-sucking pump system without rigid cylinder and plunger

A wellbore pump for using in petroleum production. The pump comprises a reciprocating hydraulic parts that presses fluid through a hydraulic fluid tube, and lets reciprocating influx and efflux of fluid in a chamber force the nonmetallic elastic tube deformation and recovery. Then the extracted liqu...

Summary:A wellbore pump for using in petroleum production. The pump comprises a reciprocating hydraulic parts that presses fluid through a hydraulic fluid tube, and lets reciprocating influx and efflux of fluid in a chamber force the nonmetallic elastic tube deformation and recovery. Then the extracted liquid in pump chamber is exalted when the influx valve and efflux valve switch repeatedly, and petroleum at bottom of a well is pumped to ground continuously. This nonplunger and nonrigid pump system avoids the wearing out of plunger by sand entirely.
