Description
Technical field
The utility model relates to a kind of wireless drilling measureing equipment, particularly a kind of wireless drilling pulser pulse combined adjusting device.
Background technology
The application of wireless drilling measurer in petroleum drilling engineering is more and more general, and the transmission of drilling liquid pressure fluctuation signal transmits the most practical reliable method of data earthward from down-hole at present, the generation of drilling fluid signal is by being discharged to annular space to realize by part drilling fluid, also can be realized by the flowing of restriction drilling fluid in drill string, MWD pulser in the course of the work, the frame mode that lower assembly adopts is, namely restrictor ring is fixed in short protection cylinder by jump ring, then load from the lower end of urceolus, the problem all the time brought is that the current driving mushroom head to do when twitching up and down at spring lever can carry out erosion to the end face of restrictor ring in the cavity in urceolus, affect the use of pulser.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of wireless drilling pulser pulse combined adjusting device.
Its technical scheme is: comprise restrictor ring, jump ring, urceolus, short protection cylinder, spring lever, mushroom head, screw; short protection cylinder is fixed by screw in the inside of urceolus; described short protection cylinder inside is provided with jump ring; restrictor ring is arranged on short protection cylinder; one end of described restrictor ring is fixed in short protection cylinder by jump ring; the other end of restrictor ring connects mushroom head; the outside linking springs bar of described mushroom head; spring lever drives mushroom head to do and twitches up and down, and the outside of described restrictor ring is provided with alloy sheath.
The outer face of above-mentioned restrictor ring is chamfering structure, reduces current to the impact of restrictor ring, improves the application life of restrictor ring.
The inside of above-mentioned urceolus is provided with step, and short protection cylinder is provided with groove, and the groove on the step of outer barrel and short protection cylinder cooperatively interacts.
Fix righting slide block between above-mentioned spring lever and urceolus, reduce spring lever and move back and forth the friction to outer tube inner wall caused, improve the application life of urceolus.
The beneficial effects of the utility model are: structure is simple, impulse movement flexibility and reliability, easy to operation, job success ratio is high, can reduce manpower, time greatly, shortens the cycle, this structure facilitates the assembling of restrictor ring greatly, equipment efficiency is high, and spring lever drives mushroom head to do when twitching up and down, reduces the erosion to the end face of restrictor ring in the cavity of current in urceolus.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: restrictor ring 1, jump ring 2, urceolus 3, short protection cylinder 4, spring lever 5, mushroom head 6, screw 7, righting slide block 8.
Detailed description of the invention
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises restrictor ring 1, jump ring 2, urceolus 3, short protection cylinder 4, spring lever 5, mushroom head 6, screw 7; short protection cylinder 4 is fixed by screw 7 in the inside of urceolus 3; described short protection cylinder 4 inside is provided with jump ring 2; restrictor ring 1 is arranged on short protection cylinder 4; one end of described restrictor ring 1 is fixed in short protection cylinder 4 by jump ring 2; the other end of restrictor ring 1 connects mushroom head 6; the outside linking springs bar 5 of described mushroom head 6; spring lever 5 drives mushroom head 6 to do and twitches up and down, and the outside of described restrictor ring 1 is provided with alloy sheath.
Wherein, the outer face of restrictor ring 1 is chamfering structure, reduces current to the impact of restrictor ring, improves the application life of restrictor ring.
Wherein, the inside of urceolus 3 is provided with step, and short protection cylinder 4 is provided with groove, and the groove on the step of urceolus 3 inside and short protection cylinder 4 cooperatively interacts.
In addition, between spring lever 5 and urceolus 3, fix righting slide block 8, reduce spring lever 5 and move back and forth the friction to urceolus 3 inwall caused, improve the application life of urceolus 3.
Principle: this device is by being designed to chamfering structure by the water impact end face of restrictor ring, the outside of restrictor ring is provided with alloy sheath, reduce the impact of current, the inner chamber of restrictor ring before urceolus is put into the assembling facilitating restrictor ring greatly, when spring lever drive mushroom head does and twitches up and down, reduce the erosion to the end face of restrictor ring in the cavity of current in urceolus.
The beneficial effects of the utility model are: structure is simple, impulse movement flexibility and reliability, and easy to operation, job success ratio is high, can reduce manpower, time greatly, and shorten the cycle, this structure facilitates the assembling of restrictor ring greatly, and equipment efficiency is high.
