Abstract
The utility model discloses a direction of pipe transmission special use in pit righting device to solve the problem that current ordinary direction head can only carry out single direction to transmission pipeline. The device is formed by connecting conversion coupling and direction cone, and a symmetrical equipartition 4 -8 guiding gutter on direction cone beveled tip face is installed in the guiding gutter and is right the piece. The utility model discloses a tubular column forms a dynamic suspension and the dual supporting role of machinery in the transmission motion process, the principle is: guider and transfer line bottom link, the tapered body structure that leads at first can satisfy the guide effect of single direction head, wherein the guiding gutter with right the piece promote well liquid or water column in tub cluster transmission course, the piece is right through stirring to well liquid, make guider receive the suspension centripetal force of well liquid, most and messenger rights guider and receives restraining force placed in the middle, the effect of rightting the direction has really been played, the device that effective protection was gone into the well, the instrument, the blasting apparatus, the efficiency of the work of pipe transmission operation is improved.
Description
Technical field
The utility model belongs to down-hole special purpose device, is specifically related to down-hole pipe and transmits special righting-oriented device.
Background technology
Down-hole pipe transmission operation is an important Completion measures in petroleum gas oil well, gas well, exploration well, water injection well, coal bed gas well exploration, exploitation, test, record survey technology, no matter be exploration and development conveying well logging instrument, or perforation, pressure break, increasing yield and injection measure well logging apparatus, wherein guiding device is a very important significant components.If adopt common guide head, single guide effect can only be carried out to transmission pipeline by single oblique action principle of drawing, guide head single at present can not meet the righting guide effect of down-hole pipe transmission, in the pipeline transmission of km, a few km length, pipeline is no longer linearity, but curve of approximation shape, the right rolling of left swing.The tester of going into the well and measure device, explosion apparatus is made constantly to scratch in pit shaft, clash into.Instrument, device, apparatus can not get better protection in the process of going into the well, cause exploration and development can not get reliably data, test measure effect not good.
Utility model content
The purpose of this utility model is to provide a kind of down-hole pipe and transmits special righting-oriented device, to solve existing common guide head can only carry out single guiding problem to transmission pipeline.
Technical solutions of the utility model are as follows: a kind of down-hole pipe transmits special righting-oriented device, and it is formed by connecting by combination coupling and guiding cone, and on guiding cone angled end-face, symmetry is evenly equipped with guiding gutter, in guiding gutter, be provided with body resistance-strengthening tablets.
Further, guiding gutter is 4-8.
Further, guiding cone is connected by fastening bolt matched in clearance with body resistance-strengthening tablets.
The utility model is that tubing string forms a kind of dynamic suspension and mechanical dual support effect in transmitting moving process, principle is: guiding device and transfer line bottom are connected, first the tapered body construction that leads can meet the guide effect of single guide head, wherein guiding gutter and body resistance-strengthening tablets promote well liquid or water column in pipe string transmitting procedure, well liquid is by stirring body resistance-strengthening tablets, guiding device is made to be subject to the suspension centripetal force of well liquid, centering guide device is made to be subject to restraint forces placed in the middle to the greatest extent, really serve the effect of righting guiding, the device that available protecting is gone into the well, instrument, explosion apparatus, improve the operating efficiency of pipeline transmission operation, dark in oil field, the welcome of coal gas field exploration and development user.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of down-hole pipe transmits special righting-oriented device;
Fig. 2 is the half sectional view that a kind of down-hole pipe transmits guiding cone in special righting-oriented device;
Fig. 3 is A-A view in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
A kind of down-hole pipe transmits special righting-oriented device, and it is formed by connecting by combination coupling 1 and guiding cone 2, and on guiding cone 2 angled end-face, a symmetrical uniform 4-8 guiding gutter 21, is provided with body resistance-strengthening tablets 3 in guiding gutter 21.Guiding cone 2 is connected by fastening bolt 4 matched in clearance with body resistance-strengthening tablets 3.The effect of combination coupling 1 is the exchange in order to increase centering guide device.The external diameter of guiding cone 2 determines primarily of wellbore casing, general 73mm-127mm, and that the most frequently used is 89mm, 102mm, 127mm.
This device in pit shaft transmitting procedure as freely transmitting termination, meet well liquid, well liquid is by guiding gutter 21, form umbrella fluid, and open body resistance-strengthening tablets 3, material is thus formed cone guiding, body resistance-strengthening tablets suspension righting and the dual centralizing function placed in the middle of the symmetrical mechanical support righting of multiple spot, ensure that the righting placed in the middle of the free termination of transmission pipeline, reduce friction, the scratch of pipe end and pit shaft, clash into, be hampered phenomenon.When stopping mobile, body resistance-strengthening tablets is automatically packed up and is hidden in guiding gutter, makes device recover the appearance and size of pipe fitting, avoids the phenomenon that is hampered completely.
