Design of a Novel Down-Hole Pump with Hydro-Automatic Reversing Valve

Abstract:

Ultra-high-pressure-jet-assisted drilling is a main technique for improving the rate of penetration in well drilling. In this paper, a novel down-hole pump with hydro-automatic reversing valve was designed and explained. The equipment is a kind of hydraulic piston pump in which the reversing valve, the core component of the pump, is a five-way, two-position control valve. With the explanation of the working principle, it is understood that the down-hole pump has simple operating principle. According to schematics of the assembly drawing, also it is known that the actuations of pistons, check valves and the reversing valve are not complicated. Calculation and analysis results indicate that the equipment can intensify the drilling mud to 140-170MPa within an area ratio of 9.9 and 11.9 theoretically.
