Abstract
The utility model discloses an adjustable centering sheet type drift well gauge for well testing. The drift well gauge comprises a drift well gauge body, wherein the circumferential surface of the drift well gauge body is provided with at least three sliding chutes axially; each sliding chute is provided with a spring plate; one end of the spring plate is fixed in the sliding chute, while the other end of the spring plate is movably assembled in the sliding chute; the length of the spring plate is greater than that of the sliding chute; the spring plate is arranged to an arch shape inside the sliding chute; and each sliding chute is 'V'-shaped. In the utility model, the drift well gauge and a centering device are combined into one body and the adjustable centering sheet type drift well gauge has the characteristics of being flexible to operate, convenient to use, low in labor intensity, strong in practicability, simple in structure, convenient to maintain, low in manufacturing cost and the like. The problem related to the centering of the drift well gauge during drifting process is solved and the phenomenon that a tool under a well is clamped during the drifting process is avoided to the greatest extent simultaneously when the length of a tool entering the well is reduced, therefore the adjustable centering sheet type drift well gauge can be adaptive to various models of tubular piles.
Description
Technical field
The utility model relates to a kind of oil gas well underground work construction tool, specifically is the adjustable chip drift size gauge tool of setting upright of a kind of well testing.
Background technology
At present; Existing drift size gauge tool is in the drifting process; Owing to can't remain at the center condition in the pit shaft, particularly in pit shaft when reducing well section or lower curved section, the phenomenon of card may appear meeting simultaneously in drift size gauge tool and bumper jar; Make that bumper jar can't operate as normal, finally cause the tool falling well.In order to solve this difficult problem, measure commonly used is in the drifting tool string, to add special-purpose centralizer, and this can obviously improve the drifting tool string is met card in pit shaft problem.But because the adding of special-purpose centralizer makes the length of whole drifting tool string increase, this has higher requirement to ground blowout control equipment when high-pressure gas well drifting operation, has increased the execute-in-place difficulty.This be because: the high-pressure gas well well head pressure is high, and well inner high voltage gas has the very large top power that goes up to going into the well tool string, leans on the tool string self gravitation to be not enough to overcome top power on this.Need in going into the well tool string, insert extra weighted lever in the routine work, this has increased the length of going into the well tool string greatly.But because ground blowout hookup limited length, so how when being added to well tool string weight, to reduce a great problem that just becomes high-pressure gas well well testing work into the length of well tool string.
In order to reduce the chance card phenomenon of drift size gauge tool in the drifting process; The relevant enterprise of each oil gas drilling; Also this has been strengthened the research dynamics, the drift size gauge tool of various diverse in function is of common occurrence on public publication, but do not see so far have identical with the utility model content or close.
Summary of the invention
The purpose of the utility model is: to the deficiency of above-mentioned existing drift size gauge tool; A kind of adjustable chip drift size gauge tool of setting upright is provided; It has increased when not increasing drifting tool string length sets upright function, has avoided the phenomenon of downhole tool chance card in the drifting process to take place to greatest extent.
The technical purpose of the utility model realizes through following technical proposals:
A kind of well testing is adjustable sets upright the chip drift size gauge tool; Comprise the drift size gauge tool body, be axially arranged with chute on the periphery of said drift size gauge tool body, on chute, be provided with shell fragment; One end of shell fragment is fixed in the chute; The other end is movable assembling in chute, and the length of said shell fragment is greater than the length of chute, and shell fragment is arc shape setting in chute.
Chute on the said drift size gauge tool body is at least three roads.
Said chute is " V " shape groove.
The beneficial effect of the utility model is: said structure unites two into one drift size gauge tool and centralizer; Have flexible operation, easy to use, light labor intensity, practical, simple in structure, maintenance is convenient and characteristics such as cheap; It efficiently solves the placed in the middle problem of drift size gauge tool in the drifting process; When the well tool string length is gone in shortening; Avoided the phenomenon of downhole tool chance card in the drifting process to take place to greatest extent,, can adapt to the tubing string of multiple model through the body resistance-strengthening tablets that replacing varies in size.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the A-A view of Fig. 1.
Code name implication among the figure: 1-drift size gauge tool body; 2-by-pass prot; 3-shell fragment; 4-chute; 5-fixed screw.
The specific embodiment
Referring to Fig. 1 and Fig. 2: the utility model comprises drift size gauge tool body 1; Drift size gauge tool body 1 is interior hollow structure; The middle part radially is provided with by-pass prot 2; By-pass prot 2 communicates with the inside branch of drift size gauge tool body 1, and by-pass prot 2 becomes the passage of gas flow in the well, and the bottom of drift size gauge tool body 1 links to each other with other instruments through corresponding joint with the top.On the periphery of drift size gauge tool body 1, be axially arranged with four road chutes 4; Each road chute is " V " type groove; On chute 4, be provided with shell fragment 3, the length of shell fragment 3 is greater than the length of chute 4, and the lower end of shell fragment 3 is fixed on the lower end of chute 4 through fixed screw 5; The upper end of shell fragment 3 is movable assembling in chute 4, and shell fragment 3 is arc shape setting in chute 4.
Above-mentioned chute quantity can be decided according to concrete application; Be generally four roads; Also can guarantee that in order to make it drift size gauge tool body 1 remains center condition in pit shaft, when concrete the application for three roads or five roads etc.; Chute quantity should keep three roads at least, can make the shell fragment in the chute constitute a regular circle like this.
The utility model is after going into well; Four shell fragments 3 that axially are provided with on the periphery, receive the extruding of pit shaft after, an end of shell fragment 3 elongations slides along groove in " V " type chute 4; The extruding force that varies in size according to pit shaft; Shell fragment 3 elongations that axially are provided with on drift size gauge tool body 1 periphery are also different, make drift size gauge tool body 1 can remain on the center condition in the pit shaft all the time, thereby avoid the chance card phenomenon in pit shaft.
The utility model can in time be changed the shell fragment of corresponding drift size gauge tool body and different length according to the size of preparatory drifting tubing string in practical application, very flexible.
