Abstract

The utility model relates to a novel wedge-shaped slip capable of keeping a pipe undamaged. The novel wedge-shaped slip comprises a support body, a lifting board, a lifting rod, a wedge-shaped slip and a power cylinder, wherein the wedge-shaped slip is arranged in a cavity in the middle of the support body, the power cylinder is arranged on the edge of the support body, the top end of the power cylinder is fixed with the lifting board by a nut, one end of the lifting rod is connected with the lifting board, and the other end of the lifting rod is connected with the wedge-shaped slip. The novel wedge-shaped slip has the advantages of simplicity in structure, convenience in operation and high working efficiency, and can be widely applied to the field of workover treatment in an oil field.

Description

The novel pipe dovetail slip of not hindering
Technical field
The utility model relates to the well workover of a kind of oil field and uses instrument, particularly relates to a kind of novel pipe dovetail slip of not hindering.
Background technology
Oil well repairing operation mainly is for the ordinary production that guarantees oil well or according to the production needs oil well to be overhauled, safeguards and adjusts; It is the important step that guarantees oilfield stable production, high yield; Its groundwork has: inspection pump, sand control, change filter, change envelope etc., one of them very hard work remove oil pipe, sucker rod and downhole tool exactly.Traditional operating type is continued to use in China oil field well workover for many years always, has realized the lower tubular column operation with the crescent moon elevator, and according to existing workover treatment mode, playing lower tubular column needs work such as Manual Switch elevator, dislodging suspension ring, auxiliary oil pipe location; Complex procedures, automaticity is low, and labour intensity is big, needs personnel many; Inefficiency, running into has blowout overflow or sleety weather, and normal operation will be affected; Liquid also can spray the well site in the well, makes personnel and equipment dirty, and operation is dangerous big.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of simple in structure, the easy to operate novel pipe dovetail slip of not hindering.
In order to address the above problem, the utility model adopts following technical scheme:
The novel pipe dovetail slip of not hindering comprises bearing body, lifts plate, lifting rod, dovetail slip and power cylinder, is provided with dovetail slip in the bearing body in the cavities, and power cylinder is installed by bearing body limit portion, the power cylinder top through nut with lift plate and fix; Lifting rod one end with lift plate and be connected, an end is connected with dovetail slip.
Described dovetail slip comprises slips body, elastic body and clamping bar, and elastic body and the thermosetting of clamping bar are on the slips body.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is simple in structure, and is easy to operate, can be used with existing workover rig, realizes the workover treatment automation, effectively reduced labor intensity of operating staff, improved operating efficiency and operating safety factor.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the dovetail slip structural representation.
The specific embodiment
The novel pipe dovetail slip of not hindering; As shown in Figure 1, comprise bearing body 4, lift plate 1, lifting rod 2, dovetail slip 3 and power cylinder 5, be provided with dovetail slip 3 in the bearing body 4 in the cavities; Power cylinder 5 is installed by bearing body 4 limit portions, power cylinder 5 tops through nut with to lift plate 1 fixing; Lifting rod 2 one ends with lift plate 1 and be connected, an end is connected with dovetail slip 3.As shown in Figure 2, dovetail slip 3 comprises slips body 7, elastic body 8 and clamps bar 9 that elastic body 8 and 9 thermosettings of clamping bar are on slips body 7.
In view of the characteristics of oil field tubing string, except the clamping tubing coupling, be exactly clamping oil pipe body.Clamping tubing coupling, hydraulic tongs can't operate as normal, therefore, can adopt the body of dovetail slip 3 clamping box cupling bottoms, let box cupling all expose, and provide convenience for elevator blocks box cupling.Hinder tubing string 6 surfaces for preventing that dovetail slip 3 from blocking, influence the application life and the corrosion resistance of tubing string 6, dovetail slip 3 adopts elastic body 8 and clamps bar 9 damascene structures modes with tubing string 6 contact portions.
When blocking the pipe operation, slips body 7 moves down under the driving of power cylinder 5, tentatively tightens tubing string 6, and under the effect of gravity, realizes self-tightening at tubing string 6, accomplishes the card plumber and does; When carrying out unclamp operation, power cylinder 5 is in the state of moving upward, and together upwards carries slips body 7 with proposing action on the tubing string 6, and all enlarged-diameter in the slips body 7 are unclamped tubing string 6, and box cupling is passed through, and accomplish loose card work.
