Energy saving type power system and energy saving type sidetracking drilling machine

Abstract

The invention discloses an energy saving type power system and an energy saving type sidetracking drilling machine. The energy saving type power system and the energy saving type sidetracking drilling machine are mainly used for energy saving type movable electric well drilling equipment for windowing sidetracked well construction. The energy saving type sidetracking drilling machine comprises a carrier vehicle. The carrier vehicle is provided with a derrick and a winch. The winch is connected with the power output end of an angle transmission box through a chain. An engine module and a motor module are arranged at the front portion of the carrier vehicle and connected with the power input end of a transfer case through couplers. The power output end of the transfer case is connected with the power input end of the angle transmission box and a rotary disc transmission box through couplers. The motor module is connected with the energy saving type power system, a power source can be provided for the motor module, and the potential energy of a drilling tool can be converted into electric energy to be stored in a super-capacitor energy storage module. The transfer case provides power for the angle transmission box and also provides power for the rotary disc transmission case, and a matching device, special for providing power for the rotary disc transmission case, of a conventional drilling machine is omitted. The structure is compact, and the manufacturing cost is greatly saved.

Description

technical field [0001] The invention relates to energy-storage mobile electric drilling equipment used for window sidetracking well construction, in particular to an energy-storage power system and an energy-storage sidetracking drilling rig. Background technique [0002] There is no drilling rig specially designed for the sidetracking drilling process in the existing petroleum equipment, and conventional land drilling rigs and diesel engine-driven vehicle-mounted drilling and repairing rigs are generally used instead. The disadvantages of conventional land drilling rigs in the process of sidetracking drilling are: low power utilization, high cost, high transportation costs, and long cycle; the disadvantages of vehicle-mounted drilling and repairing rigs in the process of sidetracking drilling are: pollutant emissions from diesel engines Pollution of the environment, high noise impacts construction in residential areas, and relatively high fuel costs; moreover, conventional ...

Problems solved by technology

The disadvantages of conventional land drilling rigs in the process of sidetracking drilling are: low power utilization, high cost, high transportation costs, and long cycle; the disadvantages of vehicle-mounted drilling and repairing rigs in the process of sidetracking drilling are: pollutant emissions from diesel engines Pollution of the environment, high noise impacts construction in residential areas, and relatively high fuel costs; moreover, conventional drilling equipment or workover equipment cannot recover the gravitational potential energy stored when the pipe string is lowered, and can only convert this part of energy into heat energy through brakes Consumption, and this part of potential energy in actual operation is very large, which not only reduces the service life of the equipment, but also causes a waste of energy
