Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in detail.
The utility model provides a kind of bridge-type wet joint, as shown in Figure 1, comprises interconnective male rifle 1 and female rifle 2, and the outer wall of male rifle 1 and female rifle 2 is sheathed with the housing connected and composed by long shell 3 and short shell 4 jointly, and the other end of female rifle 2 is connected with flexible torpedo 5.
As shown in Figure 2, public rifle 1 comprises the guide head 101, connecting rod 102, guide cone 103, first plunger case 104, public rifle shell 105 and the public gun joint 106 that are top to bottm connected successively; The outside of connecting rod 102, and be axially evenly provided with several public rifle conducting rings 107 along connecting rod 102, the end face of public gun joint 106 is provided with several butt holes 108, the punching direction of butt hole 108 is parallel with the axis of public rifle 1, and male rifle 1 is connected with female rifle 2 by guide head 101 and connecting rod 102.
The external diameter distribution in flaring shape successively of the guide head 101, connecting rod 102, guide cone 103, first plunger case 104, public rifle shell 105 and the public gun joint 106 that are connected successively from top to bottom.
As shown in Figure 3, female rifle 2 comprises the female gun joint 201, adapter sleeve 202, second plunger case 203, outer tube 204 and the correcting cap 205 that are from left to right connected successively, the inwall of outer tube 204 and be axially evenly provided with several dead rings 206 along it, be provided with female rifle conducting ring 207 between every two dead rings 206, outer tube 204 and correcting cap 205 joint are provided with locating ring 208; Guide head 101 and the connecting rod 102 of public rifle 1 are inserted in outer tube 204, and female rifle conducting ring 207 contacts with male rifle conducting ring 107; Locating ring 208 is for blocking long shell 3.
As shown in Figure 4, short shell 4 comprises housing 401, rotating prevention sleeve 402, tube connector 403 and thrust bearing 404 from outside to inside successively, and rotating prevention sleeve 402 is located in housing 401 cavity, and rotating prevention sleeve 402 inner sleeve has tube connector 403, and tube connector 403 is built with thrust bearing 404; Housing 401 and long shell 3 socket-connect, and thrust bearing 404 is connected with the butt hole 108 of public rifle 1.
During use, as shown in Figure 5, when logging well, first logger 9 is connected with short shell 4, short shell 4 is connected with the butt hole 108 of public rifle 1 by thrust bearing 404, and then male rifle 1 is inserted in female rifle 2, again female rifle 2 is connected with drilling rod 7, wherein cable 8 enters in drilling rod 7 from the bypass of drilling rod 7, and be connected with female rifle 2 by female gun joint 201, when logger 9 along with drilling rod 7 extend into the certain degree of depth in down-hole, the horizontal segment of oil well 6 has been entered than logger 9 as shown in Figure 5, need to reconnect one section of drilling rod 7, now only need again as previously mentioned, by female rifle 2, public rifle 1 and short shell 4 link together, then the drilling rod 7 connected is needed to be connected on female rifle 2 and short shell 4 respectively by two sections, just can continue after above-mentioned connection completes to go into the well, now cable 8 passes through the bypass of drilling rod 7 by the outside of drilling rod 7 interior shifting to drilling rod 7, and cable 8 continues to deliver to the final degree of depth needed downwards by drilling rod 7, completes step of going into the well.
In above-mentioned whole well logging, cable 8 most of the time is inner at drilling rod 7, effectively reduces the friction between cable 8 and drilling rod 7 and the borehole wall, scrapes, touches, is wound around problems such as being hampered, thus reduces logging cost, improves operating efficiency.
Conveniently carry out the connection of drilling rod at well head, short shell 4 is provided with rotating prevention sleeve 402.Concrete operation step is: male rifle 1 upper end and female rifle 2 are docking together, the more male rifle 1 connected and female rifle 2 is loaded in long shell 3.As shown in Figure 4, when long shell 3 is connected with short shell 4, thrust bearing 404 is pressed on the positioning disk of shell, connected by butt hole 108 between tube connector 403 and public gun joint 106, now will put after pivoted housing 402 is screwed to relevant position, and with a jackscrew, they be fixed, prevent from loosening.
Finally above-mentioned all devices is loaded in long shell.Be standard thread in the upper end of long shell, for jointed rod, an in-built tapered sleeve, play the guiding role to instrument.Evenly be provided with 3 pieces of righting boards in the middle part of shell, for righting male and female rifle assembly, make installation and conductive contact accurately and reliably.Shell lower end is 411 standard threads, is connected with the short shell of anti-rotation, and on the short shell of anti-rotation, symmetry is equipped with 2 sealing anti-turn screws, and these 2 screws will keep off in the outer groove of rotating prevention sleeve, play anti-rotation effect.Through above-mentioned structure design, when butt-joint operation, this engaging tool of first slinging, rotates long shell after alignment interface, and the cable of the inside there will not be to beat turns round phenomenon.This anti-rotation connector has also taken into full account flow and the sealing problem of mud, the instrument that can not damage.Therefore this anti-rotation guiding connector uses reliable, easy accessibility.
By the way, bridge-type wet joint of the present utility model, can complete the docking of drilling rod, cable, and without the need to driving slush pump when docking, effectively protect the intact of logging cable in straight well section.This bridge-type wet joint eliminates out slush pump and connects this cargo handling operation of drill with ferrule tool, and each saving logging cost 35000 yuan, business efficiency is obvious.Because cable enters in drilling rod by annular space space via bypass, can prevent logging cable and the friction between drilling rod and borehole wall granite, scrape, touch, be wound around, be hampered problem, instrument is transferred more smooth and easy, survey data is more accurate.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that detailed description of the invention of the present utility model is only limitted to this; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the utility model by submitted to claims determination scope of patent protection.
