The removing time is shortened into two to three hours from forty to fifty hours, the work efficiency is improved, and the operation cost is reduced.

Description

Novel trailing drilling platform

Affiliated technical field:

The utility model relates to a kind of oil gas field rig, supporting novel trailing drilling platform of workover rig of being applicable to.

Background technology:

Along with improving constantly of drilling technology, the movement performance of drilling and workover machines becomes the important factor that influences the drilling and repairing well operating efficiency.Particularly in the drilling and repairing well operation of rich oil area, it is mobile to require drilling and repairing machine only to finish transition with several hours or shorter time between several kilometers or shorter well site.The drilling and repairing machine rig floor is the working platform of drilling well and workover treatment, and its mode that moves influences the transition efficient of whole rig.Pull usefulness various in present domestic oil field, the structure of the car dress telescopic rig floor that drilling and repairing machine disposed is mostly: by top assembly, bottom assembly, compositions such as detachable aisle, slide plate, Mao Dao, ladder, derrick footing, adopt circle or rectangle tubing to be nested together between top assembly, the bottom assembly, fix with bearing pin, detachable aisle, ladder are arranged about the assembly of top, the anterior slide plate of hanging, the cat road is placed in the bottom, there is derrick footing at the rear portion, and correct position is installed drilling well equipment needed therebies such as driller house, rotating disk, preventer hanging apparatus, rig tool on the rig floor.During the transition of this kind rig floor, one will form member with each pulls down one by one, and two will pull down equipment mounted thereto and instrument, then, uses lorry or flat car to haul the destination, presses the process of contrary again and installs.Like this, its disassemble and assemble work amount is big, and the transportation train number is more, needs large-scale crane to cooperate, and consuming timely reaches four or five ten hours, is difficult to transition in several hours and is in place, and make the mobile expense height of drilling and repairing machine, drilling and repairing well operation movement cost height.

Summary of the invention:

The purpose of this utility model is on the basis of existing rig floor, increase linkage, be connected into one by rig floor bottom assembly and Mao Dao, form the unitized frame crossbeam, under the cooperation of dual axle and tractor, need not dismantle aisle on the rig floor, slide plate, Mao Dao, ladder, derrick footing with and on put driller house, rotating disk, preventer hanging apparatus, rig tool etc. are installed just can be efficient, the novel trailing formula rig floor of whole movement.

The utility model is to realize above-mentioned purpose by following technical solution:

This novel trailing drilling platform comprises the bottom assembly, the top assembly, with the top assembly, the column that circle between the assembly of bottom or rectangle tubing are nested together forms the rig floor main body of a frame construction, annex on it has detachable aisle, slide plate, the cat road, pipe rack, ladder, derrick footing etc., the cat road is positioned at a side of bottom assembly, it is characterized in that: be provided with linkage and link by bearing pin and bottom assembly at an end of bottom assembly, the linkage other end becomes to link with the top by slide plate, constitute the spandrel frame structure with the rig floor column, linkage and cat road slide and link, the cat road rig floor of can partly withdrawing, and fix with bearing pin by the otic placode on it, with linkage, rig floor bottom assembly is connected and fixed and is integrally formed frame beam, and the other end in cat road is provided with the towing pin that links with tractor; On the assembly of the opposite side rig floor corresponding bottom with the cat road, be provided with the strand bearing, can link with dual axle wheel carrier middle part, the position crossing at bottom assembly and column is provided with a pair of lift oil tank, links with dual axle wheel carrier end.

During mobile rig floor: be fixedly connected with cat road withdrawal rig floor and by attachment pegs and bottom assembly, the rig floor front end mentioned by the cat road with the winch on the tractor, the towing pin in cat road and the connection seat on the tractor link, and fix with pitman pin; Starting rig floor opposite side and dual axle are joining a pair of from lift oil tank, promote the rig floor built on stilts, and at this moment, the steel frame construction that the cat road is connected with the rig floor main body is equivalent to the rigid-frame of towed vehicle, start tractor, just can realize the whole movement of rig floor.

The utility model compared with prior art has following beneficial effect:

1. by increasing linkage, make the bottom assembly, column between the assembly of top is formed the triangle frame structure by slide plate, the bottom assembly, linkage, the cat road is as frame beam, cooperation by dual axle and tractor, make rig floor realize the integral moving transportation, aisle on the rig floor, rig floor assemblies such as ladder need not be dismantled, driller house, rotating disk, the preventer hanging apparatus, Hydraulic Station, preventer, equipment also need not be dismantled under rig floor faces such as rig tool and the rig floor, do not need transport vehicle to cooperate, the transition time significantly reduced to two or three hours by four or five ten hours, improve operating efficiency, reduced operating cost.

2. with from lift oil tank the rig floor afterbody being lifted movement on the assembly of rig floor bottom, need not use in addition crane, the minimizing corollary equipment.
