Technical Field

The utility model relates to an oil field machine tool, concretely relates to rotary valve pulser promotes adjustment tool.

Background

The wireless inclinometer while drilling is widely applied to various oil fields, the rotary valve pulser can be applied to a high-temperature environment, so that the application is more and more extensive, the salvaging process is carried out, a lot of troubles are caused when a seat key is used, the methods of the pulser in the salvaging process are different, the traditional salvaging mode is to pull a salvaging spear of the pulser, the salvaging mode is suitable for the pulser under the condition that the pulser is not stuck by mud or is not stuck too tightly by mud, but along with the complexity of the well condition and the change of the complex components of the mud, a plurality of pulsers are stuck by the mud to be firm, the conventional lifting is usually tripped, the instrument cannot be salvaged, and the human body can be injured seriously.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a safe efficient rotary valve pulser promotes adjustment tool to the defect that prior art exists.

The technical scheme is as follows: a lifting adjusting tool of a rotary valve pulser comprises a fishing body, a sliding block, a sliding pin, a spring, an adjusting handle, a lifting ring and a connecting pull ring, wherein the lifting ring is arranged at the upper end of the fishing body through threaded connection, the connecting pull ring is connected to the lifting ring in a sleeved mode, a long hole and two symmetrical U-shaped grooves are formed in the lower end of the fishing body, the sliding block is arranged in the long hole, the excircle diameter of the sliding block is slightly smaller than that of the long hole, the sliding block moves in the long hole, a pin hole is formed in the upper surface of the sliding block, the sliding pin penetrates through the pin hole and is connected with the U-shaped grooves through the sliding pin, therefore, the sliding block moves in the long hole of the fishing body, the moving distance is the length of the U-shaped groove, the excircle diameter of the spring is smaller than that of the long hole in the, four L-shaped claws are arranged at the lowest end of the fishing body, and the L-shaped claws and the fishing body are of an integral structure machined by a machine.

Compared with the prior art, the utility model, have following advantage: the rotary valve pulser lifting adjusting tool adopts a form of convex-concave connection with the rotary valve pulser shell cover, is convenient to operate in the fishing process, basically does not need any auxiliary tool, and saves fishing time; the rotary valve pulser lifting adjusting tool has relative independence, and once a certain part is damaged, the part can be detached in time to be replaced; the pulling area of the lifting adjusting tool of the rotary valve pulser is large, the pressure intensity is greatly reduced, and the safety of the pulser to be lifted is ensured; the rotary valve pulser lifting adjusting tool is simple in structure and low in production cost; the rotary valve pulser lifting adjusting tool can lift the pulser and adjust the seat key of the pulser, is integrated and dual-purpose, saves time and cost, and improves working efficiency.

Detailed Description

Referring to fig. 1, the lifting adjustment tool of the rotary valve pulser comprises a salvage body 1, a sliding block 2, a sliding pin 3, a spring 4, an adjustment handle 5, a hanging ring 6 and a connecting pull ring 7, wherein the upper end of the salvage body 1 is provided with the hanging ring 6 through threaded connection, the hanging ring 6 is connected with the connecting pull ring 7 in a ring mode, a long hole and two symmetrical U-shaped grooves are arranged in the lower end of the salvage body 1, the sliding block 2 is arranged in the long hole, the excircle diameter of the sliding block 2 is slightly smaller than that of the long hole, the sliding block 2 moves in the long hole, a pin hole is arranged on the sliding block 2, the sliding pin 3 penetrates through the pin hole, the sliding block 2 is connected with the U-shaped grooves through the sliding pin 3, so that the sliding block 2 moves in the long hole of the salvage body 1, the moving distance is the length of the, the spring 4 is pressed, the upper middle end of the salvaging body 1 is provided with a large hole for installing the adjusting handle 5, the lowest end of the salvaging body 1 is provided with four L-shaped claws, and the L-shaped claws and the salvaging body 1 are of an integral structure machined by machinery.

The during operation will salvage body 1 and fill in the spear of salvaging of rotary valve pulser, and spring 4 is compressed, and spring 4's effect is by its fixed sliding block of tension 2, prevents free movement about sliding block 2, and sliding pin 3's effect is the U type groove of connecting sliding block 2 and salvaging body 1, makes sliding block 2 remove one section distance about U type inslot. The function of the slide 2 is to provide space for the compression deformation of the spring 4 and also to provide a contact site for the fishing spear. Spring 4 is pressed the back, rotates rotary valve pulser and promotes adjustment tool, makes four L type claws hang the outer cover 8 of rotary valve pulser, releases this rotary valve pulser and promotes adjustment tool, makes four L type claws of salvaging body 1 tightly hang outer cover 8 motionless, at this moment, hangs rings 6 in the well site through connecting pull ring 7, makes rotary valve pulser carried out. When the pulser seat is keyed, the rotary valve pulser lifting adjusting tool is hung on the shell cover 8 to be slowly lowered, when the rotary valve pulser lifting adjusting tool reaches a specified position, the adjusting handle 5 is rotated to enable the rotary valve pulser to rotate in the drill collar, after the key is aligned with the key groove, the pulser seat key succeeds in rotating the fishing body 1, the tool is taken out, adjustment is completed, and convenience and rapidness are achieved.
