Problems solved by technology

This relocation workload is very large, requires a certain amount of time for disassembly and installation, is labor-intensive and time-consuming, and has poor safety.
Although some drilling rigs are also equipped with rail sliding devices, which can also realize the movement of the drilling rig, due to the different design and structure of the backstage of the drilling rig, part of the backstage and the equipment on the backstage still need to be hoisted to the required position separately, which cannot achieve the purpose of moving the rig as a whole

Embodiment Construction

[0046] figure 1 It is a structural schematic diagram of the overall moving device of the drilling rig in the embodiment, as figure 1 As shown, it consists of rail sliding 1, hydraulic control mechanism 4, hydraulic cylinder 6, drilling rig background 5 and drilling rig front 2. The drilling rig front 2 and drilling rig background 5 are arranged on the rail sliding 1 side by side. 5 are connected, the hydraulic control mechanism 4 is fixed on the front desk 2 of the drilling rig, the hydraulic cylinder 6 is fixed on the rail slide 1 and connected with the backstage 5 of the drilling rig, and the front desk 2 of the drilling rig is connected with the derrick 3 . When in use, it realizes the expansion and contraction of the hydraulic cylinder 6 by operating the hydraulic cylinder control mechanism 4, pushes and pulls the backstage 5 of the drilling rig to slide 1 back and forth along the track, and pushes and pulls the front desk 2 of the drilling rig through the backstage 5 of t...

Abstract

The present invention relates to driller design scheme for petroleum and gas well, and is especially one new design scheme of composite driving driller with reliable performance, compact and flexible structure and low cost. The driller platform includes winch, diesel engine, linking machine, valve assembly, clutch, hydraulic coupler, turntable, driving mechanism, drilling bit, control table, pressure converter, signal transducer, electric pressure gauge, etc. It features the turntable driven with frequency variable motor, the driving mechanism with frequency variable motor connected through the turntable box with the turntable, the drilling bit inside the turntable, the winch driven with a diesel engine, the connection of the winch with the automatic drilling bit feeding mechanism via a gear switching mechanism, etc. The present invention has reliable performance, simple first, flexible control and high interchangeability.

Description

technical field [0001] The invention relates to a drilling rig for oil and natural gas drilling, in particular to a composite drive drilling rig with reliable performance, compact structure, reasonable flexibility and low cost. technical background [0002] Drilling is required before oil and natural gas are exploited, and drilling rigs are essential equipment for drilling operations. It mainly transmits the power of each system to the drilling tool to the drill bit, so that the drill bit performs rotational movement and axial feed movement to break the rock formation, and then discharges cuttings out of the wellbore through the mud circulation system, and finally forms a wellbore. But the original rig has the following disadvantages: [0003] 1. To achieve drilling operations, a series of power transmission equipment is needed. The backstage of the drilling rig is mainly used to carry the winch, parallel box, diesel engine and hydraulic coupling and other transmission equi...
