Self-walking shale gas drilling machine

Abstract

The invention discloses a self-walking shale gas drilling machine and relates to drilling equipment. The self-walking shale gas drilling machine comprises a crown block (1), a well rack (2), a rotating table (5), a drill stand (6), a winch (12), a conveying vehicle chassis (10), a power mechanism and a hydraulic system. According to the self-walking shale gas drilling machine, the drilling equipment is arranged on the conveying vehicle chassis, so that the equipment mounting and dismounting speed is rapid; after operation is finished, the self-walking shale gas drilling machine is transferred to another place from one place with rapid speed, convenience and labor saving, so that manpower is saved, and the working strength is reduced; a single-roller hydraulic disc type brake is adopted, and an independent hydraulic source is adopted, so that safe and reliable braking is ensured, the labor intensity of a driller is reduced, and the safety and the reliability are higher; front and rear power driving modes are adopted, and the driving modes are selected according to road surface conditions, so that the passing-by reliability and safety of vehicles are ensured.

Description

technical field [0001] The invention relates to drilling equipment, in particular to a self-propelled shale gas drilling rig. Background technique [0002] With the changes in international and domestic fuel structure requirements, the demand for fuels with low carbon emissions and no carbon dioxide emissions has increased, and the supply of such energy is urgently needed. Shale gas is a clean and efficient energy source. Currently, shale gas is being explored and developed all over the world. my country is a country rich in shale gas reserves, with shale gas reserves reaching 30 trillion cubic meters. In recent years, the contradiction between the supply and demand of China's oil and gas resources has become increasingly prominent, the demand for natural gas has continued to increase, and the international market competition is fierce. Therefore, accelerating the development of shale gas is very important for changing the pattern of China's oil and gas resources, linking e...

Problems solved by technology

[0003] Shale gas drilling rigs are special equipment for developing shale gas. Since shale gas is stored in hills and mountains and buried in rock formations or coal seams at a depth of about 3,000 meters, it is required that shale gas drilling rigs can drill shale gas formations within 3,000 meters. Drill deep wells on the ground for shale gas formations to extract shale gas. In the past, large drilling rigs took up a lot of space. After entering hills and mountainous areas, it was inconvenient to move, which brought a lot of trouble to the drilling work and wasted more manpower. Material resources, but work efficiency is difficult to improve
