Abstract
The invention discloses a kind of down-hole pipes to transmit dedicated righting-oriented device, to solve the problems, such as that existing common guide head can only carry out single guiding to transmission pipeline.The device is formed by connecting by combination coupling and guiding cone, and 4-8 diversion trench is symmetrically evenly distributed on guiding cone angled end-face, body resistance-strengthening tablets are equipped in diversion trench.The present invention is that tubing string forms a kind of dynamic suspension and mechanical dual support effect in transmission motion process, principle is: guiding device and transfer line bottom end are connected, it is oriented to the guiding role that tapered body construction is able to satisfy single guide head first, wherein diversion trench and body resistance-strengthening tablets push well liquid or water column in pipe string transmission process, well liquid is by stirring body resistance-strengthening tablets, make suspension centripetal force of the guiding device by well liquid, make centering guide device by restraining force placed in the middle to the greatest extent, really play the role of righting guiding, the device that effective protection is gone into the well, instrument, explosion instrument, improve the working efficiency of pipeline transmission operation.
Description
Technical field
The invention belongs to underground dedicated units, and in particular to down-hole pipe transmits dedicated righting-oriented device.
Background technique
Down-hole pipe transmission operation is petroleum gas oil well, gas well, exploration well, water injection well, coal bed gas well exploration, opens
Hair is tested, an important Completion measures in record survey technology, either exploration and development conveying well logging tool or perforation, pressure
It splits, increasing yield and injection measure well logging apparatus, wherein guiding device is a very important significant components.If led using common
To head, single guiding role can only be carried out to transmission pipeline by single oblique action principle of drawing, guide head single at present is full
The righting guiding role of foot not down-hole pipe transmission, in the long pipeline transmission of km, a few kms, pipeline is no longer straight line
Shape, but curve of approximation shape, the right rolling of left swing.Make the test equipment gone into the well and measure device, explosion instrument constantly in pit shaft
It scratches, hit.Instrument, device, instrument cannot be protected more preferably during going into the well, and cause exploration and development that cannot reliably count
According to, test measure effect it is bad.
Summary of the invention
The object of the present invention is to provide a kind of down-hole pipes to transmit dedicated righting-oriented device, to solve existing common guiding
The problem of head can only carry out single guiding to transmission pipeline.
Technical solution of the present invention is as follows: a kind of down-hole pipe transmits dedicated righting-oriented device, it by combination coupling with lead
It is formed by connecting to cone, is symmetrically evenly equipped with diversion trench on guiding cone angled end-face, body resistance-strengthening tablets are installed in diversion trench.
Further, the diversion trench is 4-8.
Further, guiding cone is connected with body resistance-strengthening tablets by fastening bolt clearance fit.
The present invention is that tubing string forms a kind of dynamic suspension and mechanical dual support effect, principle in transmission motion process
Be: guiding device and transfer line bottom end are connected, and are oriented to the guiding work that tapered body construction is able to satisfy single guide head first
With wherein diversion trench and body resistance-strengthening tablets push well liquid or water column in pipe string transmission process, and well liquid makes to be oriented to by stirring body resistance-strengthening tablets
Suspension centripetal force of the device by well liquid makes centering guide device by restraining force placed in the middle, really plays righting and lead to the greatest extent
To effect, device that effective protection is gone into the well, instrument, explosion instrument improve the working efficiency of pipeline transmission operation, deep by oil
The welcome in field, coal gas field exploration and development user.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that a kind of down-hole pipe transmits dedicated righting-oriented device；
Fig. 2 is the half sectional view that a kind of down-hole pipe transmits guiding cone in dedicated righting-oriented device；
Fig. 3 is A-A view in Fig. 2.
Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawing.
A kind of dedicated righting-oriented device of down-hole pipe transmission, it is formed by connecting by combination coupling 1 and guiding cone 2,
It is symmetrically evenly distributed with 4-8 diversion trench 21 on 2 angled end-face of guiding cone, body resistance-strengthening tablets 3 are installed in diversion trench 21.2 He of guiding cone
Body resistance-strengthening tablets 3 are connected by 4 clearance fit of fastening bolt.The effect of combination coupling 1 is the exchange in order to increase centering guide device.
The outer diameter of guiding cone 2 is mainly determined that general 73mm -127mm, the most commonly used is 89mm, 102mm, 127mm by wellbore casing.
The present apparatus, as end is freely transmitted, meets well liquid in pit shaft transmission process, and well liquid is formed by diversion trench 21
Umbrella fluid, and body resistance-strengthening tablets 3 are opened, material is thus formed cone guidance, body resistance-strengthening tablets suspension righting and the symmetrical mechanical supports of multiple spot
The dual centralizing function placed in the middle of righting, it is ensured that the righting placed in the middle of the free end of transmission pipeline reduces the friction of pipe end and pit shaft, scrapes
It rubs, hit, be hampered phenomenon.When stopping mobile, body resistance-strengthening tablets are packed up automatically and are hidden in diversion trench, and device is made to restore the outer of pipe fitting
Shape size, avoids the phenomenon that is hampered completely.
