Description

Well head wear-resisting cover assembly and disassembly tools

Technical Field

The utility model relates to the technical field of disassembly and assembly of wellhead wear-resistant devices, in particular to a disassembly and assembly tool for a wellhead wear-resistant sleeve.

Background

Currently, in the modern drilling process, the first hole drilling operation of a drilling machine is just one. And a large-size drill bit is generally used for drilling to a preset well depth, and a corresponding sleeve is put in for well cementation. The second hole opening of the drilling machine is used for tunneling the stratum, namely two holes are formed. Drill bits with a size smaller than one casing are generally used for drilling to a preset well depth, and corresponding casings are put into the drill bit as required for well cementation. When going to three open wells, three open wells need to protect the protective sleeve of two open wells, therefore, need set up wear-resisting cover between three open wells and two open well protective sleeves, but in the in-process of installing and dismantling wear-resisting cover, because the too dark inconvenient constructor construction of drilling depth, a well head wear-resisting cover assembly and disassembly tool is urgently needed now.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the well mouth wear-resistant sleeve dismounting tool comprises a handle, wherein a screw hole is formed in the middle of the lower end of the handle; the two ends of the handle are respectively sleeved with an anti-skid sleeve; the lower end of the handle is connected with a connecting piece; the connecting pieces are hollow, and the upper ends of the connecting pieces are matched with the screw holes; the lower end of the connecting piece is welded with a chassis; the chassis is round, and square bumps are symmetrically arranged at two ends of the chassis respectively.

Preferably, the connecting piece comprises a first connecting pipe, a second connecting pipe, a third connecting pipe and a fourth connecting pipe; the upper ends of the first connecting pipe, the second connecting pipe and the third connecting pipe are respectively provided with external threads, and the lower ends of the first connecting pipe, the second connecting pipe and the third connecting pipe are respectively provided with internal threads; the first connecting pipe, the second connecting pipe and the third connecting pipe are sequentially connected through internal threads and external threads in a threaded manner; the upper end of the connecting pipe is in threaded connection with the screw hole; the four lower ends of the connecting pipe are vertically welded with the chassis.

Preferably, the brackets are respectively and vertically welded on the four sides of the connecting pipe and the upper end surface of the chassis.

Preferably, the bracket is a right triangle, and is made of iron.

Compared with the prior art, the utility model has the following beneficial effects:

1. the device is convenient for constructors to assemble tools according to different depths;

2. the device saves time, labor and cost, and has higher utilization value and economic value.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3, the present utility model provides a technical solution: the well mouth wear-resistant sleeve dismounting tool comprises a handle 1, wherein a screw hole 101 is formed in the middle of the lower end of the handle 1; the two ends of the handle 1 are respectively sleeved with an anti-slip sleeve 2, so that the handle is prevented from being taken off in the process of disassembly and assembly; the lower end of the handle 1 is connected with a connecting piece, so that constructors can assemble the handle according to different depths of the wellhead; the connecting pieces are hollow, and the upper ends of the connecting pieces are matched with the screw holes 101 for use; the lower end of the connecting piece is welded with a chassis 7; the chassis 7 is round, square bumps 701 are symmetrically arranged at two ends of the chassis, so that a constructor can conveniently buckle a tool into the wear-resistant sleeve, and the wear-resistant sleeve plays a role in fixing and buckling.

Further, the connecting piece comprises a first connecting pipe 3, a second connecting pipe 4, a third connecting pipe 5 and a fourth connecting pipe 6; the upper ends of the first connecting pipe 3, the second connecting pipe 4 and the third connecting pipe 5 are respectively provided with external threads, and the lower ends are respectively provided with internal threads; the first connecting pipe 3, the second connecting pipe 4 and the third connecting pipe 5 are sequentially connected through internal threads and external threads in a threaded manner; the upper end of the first connecting pipe 3 is in threaded connection with the screw hole 101; the lower ends of the connecting pipes IV 6 are vertically welded with the chassis 7.

Furthermore, the two sides of the connecting pipe IV 6 and the upper end face of the chassis 7 are respectively and vertically welded with a bracket 8 for supporting and fixing.
