Because the utility model protects an outer tube of ware adopts oil pipe, and the rigidity runs circles around the hose body, and inside the hose is in oil pipe, has avoided going into the defect of mode under the current hose at the in -process of going into the well, need not the frequent change jet hose that rises to run the drilling tool into the well for the success rate is implemented to this technology and efficiency improves greatly, has good economy and social.
Description
Technical field
The utility model belongs to the technical field of drilling well, is specifically related to a kind of radial jet jet hose protector.
Background technology
Radial jet drilling process technology is the novel technique of a kind of oil formation improvement volume increase of rising in the world recent years.The principle of technique is: the coiled tubing using band nozzle, act on by the hydraulic drilling of high-pressure spray on the different directions in oil reservoir and get out multiple slim-hole, lateral penetration contaminated zone, former well is allowed to increase drainage area, increase earial drainage radius and the area of former well, thus reach the object reducing oil flow resistance, volume increase.In the operation process of this process implementing, need to enter to spray in outer tubing string by under about 100 meters flexible pipes, in well in operation reservoir, then get out multiple apertures of different directions.Because mostly current technology is directly flexible pipe to be connected in coiled tubing bottom, a measure is lowered into without any guarantee, therefore enter mode under existing flexible pipe and have obvious defect, as: rigidity is not enough, easy beating is turned round and easily hinder extension etc., ejection efficiency can be caused low, need the replacing jet hose that frequently makes a trip, even operation failure, this process implementing success rate and efficiency are reduced, and easily causes equipment damage and economic loss.
Above-mentioned discussion content object be to reader introduce may to below by the various aspects of technology relevant for the various aspects of the present utility model be described and/or advocate, believe that this discussion content contributes to for reader with background's information, to be conducive to understanding various aspects of the present utility model better, therefore, should be appreciated that it is discuss to read these with this angle, instead of admit prior art.
Utility model content
The purpose of this utility model is avoid deficiency of the prior art and provide a kind of radial jet jet hose protector, and it enters mode rigidity deficiency, easily beats the defect turned round and easily hinder extension can avoid existing flexible pipe in the process of going into the well under.
The purpose of this utility model is achieved through the following technical solutions:
A kind of radial jet jet hose protector is provided; comprise sealing shroud; interior pipe is provided with in described sealing shroud; the lower end connecting hose of described interior pipe; fixed by shear pin between described outer wall of inner tube and sealing shroud inwall, the lower end of described sealing shroud is connected with Big Inch by large two female box cupling, and the lower end of described Big Inch is connected with little oil pipe by variable buckle; described little oil pipe is connected with guiding guide shoe by little two female box cupling, and described flexible pipe extends in guiding guide shoe through Big Inch, little oil pipe inside.
Wherein, described Big Inch is many, is connected between two Big Inch by large two female box cupling.
Wherein, described shear pin has two at least, and shear pin is distributed on same sagittal plane.
Wherein, described sealing shroud outer setting has exterior seal ring.
Wherein, described sealing shroud outer wall is provided with multiple closure gasket groove, is provided with an exterior seal ring in each closure gasket groove.
Wherein, inner seal ring is provided with between described outer wall of inner tube and sealing shroud inwall.
The beneficial effects of the utility model: the outer tube due to the utility model protector is all adopt oil pipe; rigidity substantially exceeds hookah bodies; and flexible pipe is in oil pipe inside; the defect of mode is entered avoid existing flexible pipe in the process of going into the well under; as: rigidity is not enough, easy beating is turned round and easily hinder extension etc., and ejection efficiency improves greatly, without the need to frequently making a trip replacing jet hose; this process implementing success rate and efficiency are improved greatly, there is good economic and social benefit.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the following drawings.
Fig. 1 is the structural representation of radial jet jet hose protector.
Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, it should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
Core of the present utility model is to provide a kind of radial jet jet hose protector, and it enters mode rigidity deficiency, easily beats the defect turned round and easily hinder extension can avoid existing flexible pipe in the process of going into the well under.
As shown in Figure 1; radial jet jet hose protector described in the utility model; comprise sealing shroud 1; described sealing shroud 1 outer setting has exterior seal ring 3; concrete; described sealing shroud 1 outer wall is provided with three closure gasket grooves, is provided with an exterior seal ring 3 in each closure gasket groove, and exterior seal ring 3 is O type circle.Be provided with interior pipe 5 in described sealing shroud 1, be provided with inner seal ring 2 between described interior pipe 5 outer wall and sealing shroud 1 inwall, inner seal ring 2 is O type circle.Fixed by shear pin 4 between described interior pipe 5 outer wall and sealing shroud 1 inwall, described shear pin 4 has two at least, and shear pin 4 is distributed on same sagittal plane.The lower end of described sealing shroud 1 is connected with Big Inch 7 by large two female box cupling 6, and described Big Inch 7 is many, and connected by large two female box cupling 6 between two Big Inch 7, Big Inch 7 is 1.9 ＂ oil pipes, and large two female box cupling 6 is the two female box cuplings of 1.9 ＂.The lower end of described Big Inch 7 is connected with little oil pipe 11 by variable buckle 8, and little oil pipe 11 is 1.315 ＂ oil pipes, and described little oil pipe 11 is connected with guiding guide shoe 10 by little two female box cupling 9, and little two female box cupling 9 is the two female box cuplings of 1.315 ＂.The lower end connecting hose 12 of described interior pipe 5, described flexible pipe 12 extends in guiding guide shoe 10 through Big Inch 7, little oil pipe 11 inside.Outer tube due to the utility model protector is all adopt oil pipe, and rigidity substantially exceeds hookah bodies, and flexible pipe is in oil pipe inside, enters the defect of mode in the process of going into the well under avoiding existing flexible pipe, as: rigidity is not enough, easy beating is turned round and easily hinder extension etc.
