Device for Deep Drilling mud pump, jet pump and Sealing for the same

摘要

This Invention relates to the drilling of Wells to extract oil or Gas and aims to decrease the Fluid pressure of the Fund with a minimum expenditure of Energy during the PerfoRationWhich is obtained by isolating this area from the rest of the Pit using a Rotary Shutter and Expandable that closes off the space between the device and the walls of the Borehole and can travel on theseFollowing the deepening of the walls and to maintain the isolation of the Fund and a single jet pump that creates a depression that is transmitted to the Fund through the device.The jet pump is located in front of the bit and hydraulically in series to form a closed circuit circulation through the Fund and the rest of the deviceThis Way It recovers all the Energy used in the jet pump and reverses in the cleaning of the Fund.This Pump makes a Movement independent of the driving Fluid injected from the parasite surface and the liquid from the cleaning of the AugerThe latter through an area sufficient to pass the Rock cuts without entering the flow of the Fluid Driving clean the bit.
