Available improved simultaneous Recovery of Fluids and gases in oil extraction Wells.

摘要

Simultaneous provision of enhanced recovery of gaseous and Liquid Fluids in oil extraction Wells, applicable in Facilities for Oil and gas extraction Wells in Oilfield by the use of a Dewatering device,Comprising a drawer bearer of the driving mechanisms of the installation for the extraction of available Reservoir Fluids in the wellbore, and the drawer connected to an Intake Pipe of the well Fluids from the Reservoir, a set of Well Head device and a Tip Or Bucket arranged in the pipe coating well.Between a Reel stayed in the drawer bucket and the Upper end extends along the intake duct, a steel cable, which is to ascend and descend The Bucket.In the intake duct defines a Zone of Fluid pressure hermetically separated from the drawer bearer of the mechanisms driving through a rubber Seal ring, which defines an area of Fluid pressure to the side of the well, and a Zone Free of pressure to the side of the drawer Port Designer of the driving mechanisms. Through the annular Seal is deslizablemente steel cable.The area of Fluid pressure includes a bypass duct defining a discharge Fluid Liquid. Between the seal ring and the drawer bearer mechanisms driving a discharge Tube is provided with a swing mechanism is housed to compensate for differences in tension of the Traction Rope Bucket. The whole Wellhead includes a safety valve.The Arrangement includes a Fluid Recirculation Circuit which comprises a transfer Pump Connected, on the one hand, the entry of a Fluid Storage Tank and, on the other hand, the output of a Recirculation Pump Fluid from the Storage Tank into the pump. Transfer,The Recirculation Pump defines a means of Lubrication and the seal stator of the transfer Pump.
