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 PerfoRation, which is obtained by isolating this area from the rest of the well by an Expandable and rotating Shutter closed almost all of the space between the device and the walls of the Borehole.Can move following the deepening while maintaining isolation of the Fund; and a single jet pump that creates a depression that is transmitted to the Fund through the device.The device adopts a parallel System of Movement between the Power Supply Circuit of the jet pump and the circuit Parasite that clean the bit which allows for both CircuitS maximum simplicity and effectiveness.The jet pump allows its implementation measures provide the optimum Hydraulic parameters of it and at the same time its construction allows you to eventually expand their diameters.Ra Pass large chunks of Rock CUTS. The Valve is constructed of metal parts that are compact, Robust and reliable at any depth.
