Abstract
The utility model relates to an oil, colliery and prospecting drilling system MWD instrument deviational survey technical field, an it is wireless along with boring inclinometer with circulation cover convenient to dismantle, including circulation cover body, fixed key, pin, restrictor ring, top cover, the top cover is through screw thread and circulation cover body sub -unit connection to fix restrictor ring that this is internal at circulation cover, fixed key fixes through the pin that this is internal at the circulation cover, this circulation cover simple structure, resistantly wash away, convenient to detach change restrictor ring and fixed key.
Description
Art
The utility model be related to oil, colliery and geological prospecting well system MWD instrument battering methods field and in particular to
A kind of easy-to-dismount circulating sleeve for wireless directional tool.
Background technology
Get more and more with wellbore construction, the utilization rate also more and more higher to wireless drilling inclinometers (MWD), and circulating sleeve
Produce the part of pressure signal as MWD product, the effect played is also particularly significant.Restrictor ring above circulating sleeve and pulser
On main valve head cooperation, produce pressure signal.With the change of the conditions such as the depth of drilling well, mud density, flow velocity, often need
Change the restrictor ring on circulating sleeve, to ensure signal strength signal intensity within the resolving range of receiving instrument.In prior art, circulating sleeve
Using 3 holding screw set current limiting rings on circumference, hole on down-hole, circumference for the instrument is easy to be rushed damage or is blocked up by mud
Live, holding screw cannot be dismantled after leading to well, thus restrictor ring cannot be changed, lead to circulating sleeve to be scrapped.
Content of the invention
The utility model provides a kind of easy-to-dismount circulating sleeve for wireless directional tool, overcomes above-mentioned deficiency,
Effectively solve after well is extracted in circulation because reason is damaged in punching it is impossible to change restrictor ring, lead to the problem that circulating sleeve is scrapped.
The utility model solves its technical problem and be employed technical scheme comprise that：A kind of easy-to-dismount wireless drilling deviational survey
Instrument circulating sleeve is made up of circulating sleeve body, directional bond, pin, restrictor ring, top cover five part, and wherein top cover is passed through screw thread and followed
Ring set body connects, and restrictor ring is fixed on circulating sleeve body, and directional bond is fixed by pin and circulating sleeve body.
The beneficial effects of the utility model are：Restrictor ring and directional bond are fixed on circulating sleeve originally by screw thread and pin respectively
On body, it is to avoid fix using holding screw, it is conveniently replaceable restrictor ring and directional bond, it is to avoid holding screw occurs after instrument goes out well no
Method dismantles phenomenon.
Brief description
With embodiment, the utility model is further illustrated below in conjunction with the accompanying drawings：
Fig. 1 is a kind of structural representation of easy-to-dismount circulating sleeve for wireless directional tool；
In figure：1 circulating sleeve body, 2 directional bonds, 3 pins, 4 restrictor rings, 5 top covers
Specific embodiment
As shown in figure 1, restrictor ring (4) is pushed in restrictor ring mounting groove below circulating sleeve body (1), then by top cover
(5) pass through screw thread, be fastened on circulating sleeve body (1) lower end, and restrictor ring (4) is fixed in circulating sleeve body (1), directional bond
(2) it is fixed on circulating sleeve body (1) by pin (3).Circulating sleeve body (1) is threaded connection with top cover (5), does not tie
Structure be mutated, down-hole wash away deformation less, after not resulting in out well, restrictor ring cannot change phenomenon；Directional bond (2) passes through pin
(3) fixing with circulating sleeve body (1), it is to avoid using screw, go out convenient dismounting after well.By said structure, avoid completely because following
The punching of ring set set screw hole is damaged, blocking, leads to not change the generation of restrictor ring phenomenon.
Claims (2)
1. a kind of easy-to-dismount circulating sleeve for wireless directional tool, it is characterized in that by circulating sleeve body (1), directional bond (2),
Pin (3), restrictor ring (4), top cover (5) composition, circulating sleeve body (1) is connected by pin (3) with directional bond (2), limit
Stream ring (4), top cover (5) load from circulating sleeve body (1) bottom, and top cover (5) passes through screw thread and circulating sleeve body (1) connects.
2. according to claim 1 a kind of easy-to-dismount circulating sleeve for wireless directional tool it is characterised in that restrictor ring
(4) it is Hardmetal materials.
