Abstract
An auxiliary jam release device for coal bed gas drilling is applied to the treatment of jamming accidents in the coal bed gas field during drilling. The auxiliary jam release device is mainly composed of a drilling platform, a hydraulic telescopic lifting system, a base and a drill rod slip; a drill rod slip mounting hole is formed in the center of the drilling platform; the drill rod slip is arranged in the drill rod slip mounting hole; and the hydraulic telescopic lifting system is arranged between the drilling platform and the base, that is, the hydraulic telescopic lifting system is fixed at the upper part of the base, and the drilling platform is fixed at the upper part of the hydraulic telescopic lifting system. The utility model has the beneficial effects that the jam release capability of a drilling rig can be effectively improved; and the device can provide the maximal auxiliary lifting capacity of 100 tons based on the realization of the original lifting capacity of the drilling rig, thereby improving the capability of treating the jamming accidents of the drilling rig.
Description
Technical field
The utility model relates to drilling technology field, gas field, coal seam, and the device that particularly a kind of coal bed gas drilling well lock of tool drilling is handled is a kind of auxiliary unfreezing power that provides, and improves the auxiliary unfreezing isolated plant of the unfreezing ability of coal bed gas rig.
Background technology
In the coal bed gas drillng operation, the general well depth of coal bed gas well so special drilling machine or the little tonnage oil-well rig of adopting carries out drillng operation more, improves coal bed gas drillng operation economy about 1000m.Because the particularity that the coal bed gas drilling geology is loose, lock of tool drilling repeatedly takes place.At present, the Treating Jammed Bit Accident ability is by the hoisting power decision of rig, and the big unfreezing ability of rig lifting force is strong, because the lifting force of special drilling machine or little tonnage oil-well rig is less, most bit freezing wells because of scrapping in unfreezing, and loss is serious.If adopt big load rig to carry out operation, the unfreezing ability promotes to some extent, but comprehensive drilling benefit is relatively poor.
The utility model content
The purpose of this utility model is: provide a kind of coal bed gas drilling well to assist release device, can cooperate with rig, auxiliary unfreezing lifting force is provided, improve rig integrated treatment accident ability.Realize cooperating, strengthen the Treating Jammed Bit Accident ability, improve the comprehensive benefit of coal bed gas drilling well with coal bed gas special drilling machine or little tonnage rig.
The technical solution adopted in the utility model is: release device is assisted in the coal bed gas drilling well, mainly form by offshore boring island 1, hydraulically extensible jacking system 2, base 3 and drill pipe slip 4, at offshore boring island 1 center the drill pipe slip installing hole is arranged, drill pipe slip 4 is arranged in the drill pipe slip installing hole.Drill pipe slip 4 can block drilling-rod external wall.It is characterized in that: between offshore boring island 1 and base 3, hydraulically extensible jacking system 2 is arranged.Be that hydraulically extensible jacking system 2 hydraulic cylinders are fixed on base 3 tops, be fixed with offshore boring island 1 on the contract top of jacking system 2 hydraulic cylinders of pressure stretch.Adopt hydraulically extensible jacking system 2 to realize the vertical lift of offshore boring island 1.When lock of tool drilling took place, drilling rod 5 was stuck in the down-hole.Carry drilling rod 5 tops on the rig 6, upper lifting force is little can not realize drilling rod 5 unfreezings.At this moment can adopt hydraulically extensible jacking system 2 to carry out service hoisting drilling rod 5 simultaneously.Service hoisting drilling rod 5 way be: utilize drill pipe slip 4 chucking drilling rods 5 outer walls; Start hydraulically extensible jacking system 2, push away offshore boring island 1 on the hydraulic cylinder of hydraulically extensible jacking system 2, increase a service hoisting power for drilling rod 5, increase the upper lifting force of drilling rod 5, finally realize the purpose of unfreezing by drill pipe slip 4.
The quantity of the hydraulic cylinder of described hydraulically extensible jacking system 2 is 4～12.Total maximum lift is 100 tons.
The range 2.5m of described hydraulically extensible jacking system 2 hydraulic cylinders can effectively realize the unfreezing purpose.This Design of device can be expanded and be applied to the hydraulic lifting rig floor, when realizing the rig floor lifting, realizes auxiliary unfreezing.
The beneficial effects of the utility model: release device is assisted in the drilling well of the utility model coal bed gas, can effectively improve rig unfreezing ability, this device is implemented on the basis of the original hoisting power of rig, and maximum 100 tons service hoisting power is provided again, improves the ability of rig Treating Jammed Bit Accident.

The specific embodiment
Embodiment 1: with the auxiliary release device of a coal bed gas drilling well is example, and the utility model is described in further detail.
Consult Fig. 1.Release device is assisted in the coal bed gas drilling well, mainly is made up of offshore boring island 1, hydraulically extensible jacking system 2, base 3 and drill pipe slip 4.At offshore boring island 1 center the drill pipe slip installing hole is arranged, a drill pipe slip 4 is arranged in the drill pipe slip installing hole.
A hydraulically extensible jacking system 2 is arranged between offshore boring island 1 and base 3.Be that hydraulically extensible jacking system 2 hydraulic cylinders are fixed on base 3 tops, be fixed with offshore boring island 1 on the contract top of jacking system 2 hydraulic cylinders of pressure stretch.
The quantity of the hydraulic cylinder of hydraulically extensible jacking system 2 is 8.The range 2.5 of each hydraulic cylinder, lifting force are 12 tons.
