Abstract: F-1600HL high pressure drilling pump is developed to meet the demand of drilling process for deep well, super-deep well, horizontal well with a large displacement and high pressure jet drilling. The maximum discharge pressure of the pump is 52MPa, the highest pressure of the drilling pump with the same power in China at the present time and 50.7 percent higher as compared to F-1600 drilling pump. The maximum flow rate of the pump is 51.8L/s, 11.4 percent higher than F-1600 drilling pump. It adopts new structures and new technologies, such as a L-shaped cylinder, bimetal liner, high-pressure valve seat with stress relief groove, high temperature resistant and OBM resistant high-pressure piston and inner and outer surface of liner cooling installation. The reliability of the drilling pump is ensured owing to structural finite element analysis, optimized design and drilling fluid medium test. Currently, it has been successfully used in the rigs for drilling 7000-meter-deep wells and even deeper wells. This equipment provide powerful support for application of high-pressure jet drilling process.
