Shale gas drilling rig

Abstract

The invention discloses a novel shale gas drilling machine which comprises bases, a derrick, a power device, transmission mechanisms, linkage devices, a rotating disc, a winch, a runner wagon, a high pressure pipeline, slush pumps and a gas control system. The power device comprises three sets of diesel engines which are connected with the slush pumps and the winch respectively through the linkage mechanisms and the transmission mechanisms, the winch is a sealed water-cooled type winch, the bases comprise the front table base and the rear table base, the winch, the rotating disc and a rotating disc transmission device are arranged on the front table base, and the power device and the linkage devices are arranged on the rear table base. The novel shale gas drilling machine has the advantages that due to the fact that the sealed water-cooled type winch is adopted, a centrifugal pump forced circulating water cooling mode is adopted for cooling roller friction hubs, and the main roller friction hub is provided with a water jacket and a water circulating pipeline; the three sets of diesel engines are adopted in the power device, the linkage mechanisms are arranged between the three sets of diesel engines, and power is enlarged; the two sets of 3NB-13000C slush pumps are arranged, and the need of jetting well drilling can be met.

Description

technical field [0001] The invention relates to the technical field of oil drilling equipment, in particular to a shale gas drilling rig. Background technique [0002] Shale gas drilling rigs refer to mechanical equipment that drives drilling tools to break rocks and drill underground to obtain oil or natural gas in oil drilling. [0003] A commonly used shale gas drilling rig is mainly composed of a power machine, a transmission machine, a working machine and auxiliary equipment. Generally, there are eight major systems (hoisting system, rotating system, drilling fluid circulation system, transmission system, control system, power drive system, drilling rig base, drilling rig auxiliary equipment system), which must have tripping and tripping capabilities, rotary drilling capabilities, and circulation washing. Well capacity, its main equipment includes: derrick, crown block, drawworks, swimming block, hook, turntable, faucet (power faucet) and drilling pump (called eight ma...

AI Technical Summary

Problems solved by technology

[0004] However, through research on existing shale gas drilling rigs, it is found that there are the following problems: the drawworks used in existing drilling rigs use band brakes, which are prone to heat during use, which directly affects the safety performance of drilling rigs; The drilling rig is only equipped with a set of mud pumps, which cannot meet the needs of use
