Abstract

The invention discloses a drill power system, which comprises a diesel engine (15), a motor A (16), a motor B (17), a compound box, a winch (18), a slurry pump A (19) and a slurry pump B (20), wherein a crankshaft of the motor A (16) is connected with an input shaft A (2); a crankshaft of the diesel engine (15) is connected with an input shaft B (3); a crankshaft of the a motor C is connected with an input shaft C (4); an output shaft A (5) is connected with the winch (18); the output shaft B (6) is connected with the slurry pump A (19); and an output shaft C (7) is connected with the slurry pump B (20). The drill power system has the beneficial effects that: the energy-saving effect is improved remarkably, noise is lowered effectively, and zero emission of oil smoke is realized; and a hydraulic coupler is adopted, so that impact and vibration can be eliminated, high overload protection performance and starting performance are achieved, chain parallel operation is realized, transmission is flexible, and good vibration prevention and vibration insulating effects are achieved.

Description

technical field [0001] The invention relates to the technical field of oil drilling equipment, in particular to a drilling rig power system. Background technique [0002] Drilling rigs are necessary equipment for oil exploration and development. Drilling equipment is the largest energy-consuming equipment for oil field development. At present, the main equipment for power supply for drilling equipment is generators, most of which are driven by diesel engines. The daily consumption of diesel is large, and the workload of regular maintenance is also high. Larger, more than 10 tons of soot and nitrogen oxides are discharged monthly, which has caused great pollution to the environment. At the same time, due to the aging of a large number of diesel engines, the consumption of diesel and engine oil is increasing year by year, and the cost of drilling use and maintenance remains high. In addition, many drilling sites are located in densely populated areas. While the diesel generat...
