[0047] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the specification of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0049] See also Figure 1-Figure 8The utility model provides a wellhead cable and a hydraulic speed matching device.

It should be noted that in the utility model, the axial direction refers to the direction of the rotation center axis of the second connecting mechanism 3, that is, the common direction with the center axis, and the radial direction is perpendicular to the axial direction.

[0050] Furthermore, the fixing mechanism 1 is a part used to detachably connect the surface cable with the downhole cable, and includes: a fixing member 11, and a first connecting channel 12, a second connecting channel 13 and a third connecting channel 14 arranged in the fixing member 11. In one embodiment, the fixing member 11 can be connected to the equipment at the wellhead, so that the fixing mechanism 1 is arranged at the wellhead.

[0051] In some embodiments, the first connecting channel 12 is vertically arranged in the fixing member 11, and the second connecting channel 13 is horizontally arranged in the fixing member 11 and communicated with the first connecting channel 12; wherein, the first connecting channel 12 is connected to the first connecting mechanism 2, and the second connecting channel 13 is connected to the second connecting mechanism 3, so that the first connecting mechanism 2 and the second connecting mechanism 3 are connected at the connection between the first connecting channel 12 and the second connecting channel 13, so as to realize the connection process between the uphole cable and the downhole cable; the third connecting channel 14 is horizontally arranged in the fixing member 11 and communicated with the first connecting channel 12, and the third connecting channel 14 is used to accommodate the hydraulic connecting mechanism 4, so as to connect the downhole hydraulic equipment with the uphole hydraulic equipment.

[0052] Furthermore, the first connecting mechanism 2 is the part that connects the downhole cable to the wellhead, and includes: a first connecting head 21, a fourth connecting channel 22 and a cable fixing member 23 arranged in the first connecting head 21; wherein, the first connecting head 21 is connected to the fixing member 11, and the cable fixing member 23 is connected to the downhole cable, thereby connecting the downhole cable to the wellhead.

[0053] In one embodiment, the top of the first connecting head 21 is a salvage portion 211 that is wide at the top and narrow at the bottom. By designing the salvage portion 211 to be a funnel shape that is wide at the top and narrow at the bottom, on the one hand, the salvage portion 211 is fixed to the top of the fixing member 11; on the other hand, the operator can also use the salvage equipment to remove the first connecting mechanism 2 from the fixing mechanism 1, inspect and maintain the first connecting mechanism 2, or install the first connecting mechanism 2 in the fixing mechanism 1.

[0054] Furthermore, the first connecting head 21 is a cylindrical structure, and a guide slide 212 adapted to the fixing member 11 is provided on its outer circumference. In one embodiment, a guide member 111 is provided on the inner wall of the fixing member 11, and the guide member 111 cooperates with the guide slide 212 to turn the first connecting head 21 to a preset position to facilitate the subsequent docking of the first connecting mechanism 2 and the second connecting mechanism 3. The specific docking process will be further described below.

[0055] Furthermore, the guide slide 212 includes an inclined guide section 2121, and a vertically arranged downward section 2122 connected to the guide section 2121; wherein the guide section 2121 is used to guide the first connector 21 to turn to a preset direction after abutting against the guide member 111, and the downward section 2122 is used to guide the first connector 21 to slide down to a preset position after abutting against the guide member 111. In one embodiment, the guide member 111 is a guide pin, and after the guide pin abuts against the guide section 2121, under the action of the first connector 21's own gravity, the first connector 21 will turn along the setting direction of the guide section 2121 until the guide pin slides into the downward section 2122, so that the first connector 21 slides into the fixing member 11 along the preset direction; by presetting the length of the downward section 2122, the first connector 21 slides down to the preset position in the fixing member 11.

[0056] In one embodiment, the guide slide 212 is a vertically arranged inverted Y-shaped structure. It can be understood that by setting the tops of the two guide sections 2121 to be close to each other, after any section of the guide slide 212 abuts against the guide pin, the guide pin can eventually slide into the downward section 2122, thereby ensuring that the first connecting head 21 can always slide into the fixing member 11 in a preset direction, thereby ensuring the accuracy of the first connecting mechanism 2 and the second connecting mechanism 3 when they are docked with each other.

[0057] In one embodiment, the guide section 2121 is spiral-shaped. By setting the guide section 2121 to be spiral-shaped, the first connector 21 can turn more smoothly.

[0058] Furthermore, the fourth connecting channel 22 is an L-shaped structure for accommodating the downhole cable and pulling the downhole cable to the wellhead. In one embodiment, a plurality of groups of electrode heads 221 are provided in the fourth connecting channel 22. The electrode heads 221 are L-shaped structures adapted to the fourth connecting channel 22. The vertically arranged part thereof is connected to the downhole cable, and the horizontally arranged part thereof is connected to the second connecting mechanism 3, thereby realizing the detachable connection process between the first connecting mechanism 2 and the second connecting mechanism 3.

[0059] In one embodiment, the cable fixing member 23 is connected to one end of the downhole cable, so as to connect the downhole cable to the wellhead and fix it in the fourth connecting channel 22 .

[0060] Furthermore, the first connecting mechanism 2 also includes: a first telescopic cylinder 24, and a second telescopic cylinder 25; wherein, the first telescopic cylinder 24 and the second telescopic cylinder 25 are both hollow structures, and the downhole cable is connected to the downhole equipment after passing through the hollow parts of the first telescopic cylinder 24 and the second telescopic cylinder 25 in turn, and the first telescopic cylinder 24 and the second telescopic cylinder 25 have a certain rigidity and hardness, which can effectively avoid mechanical collision damage to the downhole cable, thereby playing a certain protective role.

[0061] In one embodiment, one end 24 of the first telescopic cylinder is connected to the fixing member 11 via a pin, so that the first telescopic cylinder 24 is fixed in the fixing mechanism 1. In one embodiment, one end of the first telescopic cylinder 24 away from the cable fixing member 23 is connected to the second telescopic cylinder 25, and by movably connecting the first telescopic cylinder 24 and the second telescopic cylinder 25 and adjusting the position of the second telescopic cylinder 25, an operating space is reserved for connecting the downhole cable, thereby enhancing practicality.

[0062] Furthermore, one end of the first telescopic cylinder 24 and the second telescopic cylinder 25 connected to each other is a buckle structure, so that the second telescopic cylinder 25 can slide along the first telescopic cylinder 24, thereby realizing the telescopic process after the first telescopic cylinder 24 and the second telescopic cylinder 25 are connected. In one embodiment, by making one end of the first telescopic cylinder 24 and the second telescopic cylinder 25 connected to each other a buckle structure, the first telescopic cylinder 24 and the second telescopic cylinder 25 can realize the telescopic process after being connected, but will not separate.

[0063] In one embodiment, a connecting hole 241 is formed on the first telescopic cylinder 24, and a fixing pin 251 matched with the connecting hole 241 is formed on the second telescopic cylinder 25. The operator can lock the first telescopic cylinder 24 and the second telescopic cylinder 25 with each other by connecting the fixing pin 251 with the connecting hole 241.

[0064] Furthermore, the second connecting mechanism 3 is the part that connects the uphole cable to the wellhead, and the communication process between the uphole equipment and the downhole equipment is realized by connecting the second connecting mechanism 3 with the second connecting mechanism 3 in the fixing mechanism 1, wherein the second connecting mechanism 3 is a cylindrical structure, and the second connecting mechanism 3 can be connected to the first connecting mechanism 2 in the fixing member 11 by plugging the second connecting mechanism 3 with the second connecting channel 13.

[0065] In some embodiments, a fan-shaped anti-twist groove 222 is provided in the fourth connecting channel 22, and an anti-twist key 31 adapted to the anti-twist groove 222 is provided on the outer periphery of the second connecting mechanism 3. The anti-twist key 31 and the anti-twist groove 222 cooperate with each other to radially lock the second connecting mechanism 3 in the second connecting channel 13. On the one hand, it prevents the second connecting mechanism 3 from rotating freely in the second connecting channel 13, and on the other hand, it can also realize the positioning of the second connecting mechanism 3 in the second connecting channel 13.

[0066] Furthermore, a fifth connecting channel 26 is provided in the first connecting head 21 , and the fifth connecting channel 26 is connected to the hydraulic connecting mechanism 4 , so that the hydraulic equipment downhole is connected to the hydraulic equipment above the well via the fifth connecting channel 26 .

[0067] In some embodiments, a plurality of sixth connecting channels 32 adapted to the electrode head 221 are provided in the second connecting mechanism 3, a connecting ring 2211 is provided on one end of the electrode head 221 connected to the second connecting mechanism 3, and an elastic contact piece 321 adapted to the electrode head 221 is provided in the sixth connecting channel 32. By providing the elastic contact piece 321 in the sixth connecting channel 32, when the second connecting mechanism 3 is plugged into the electrode head 221, the connecting ring 2211 first enters the sixth connecting channel 32, and then contacts the elastic contact piece 321 to compress and deform the elastic contact piece 321 and then continues to move forward. Finally, after the connecting ring 2211 passes through the elastic contact piece 321, the elastic contact piece 321 will limit the connecting ring 2211 after recovering the deformation, so that the second connecting mechanism 3 is axially locked in the second connecting channel 13 by using the electrode head 221, thereby realizing the automatic quick locking function after the first connecting mechanism 2 is connected to the second connecting mechanism 3.

[0068] Furthermore, the hydraulic connection mechanism 4 includes: a first hydraulic connector 41, a second hydraulic connector 42 adapted to the first hydraulic connector 41, and a pressure cylinder 43 connected to the second hydraulic connector 42. In some embodiments, the first hydraulic connector 41 is connected to the downhole hydraulic equipment. Further, a first internal thread is provided in the fifth connecting channel 26, and the first hydraulic connector 41 is threadedly connected to the fifth connecting channel 26 via the first internal thread, thereby fixing the first hydraulic connector 41 in the first connecting head 21.

[0069] It is understandable to those skilled in the art that the first hydraulic connector 41 and the second hydraulic connector 42 can be rotated after being aligned, so that the first hydraulic connector 41 and the second hydraulic connector 42 are connected and then locked.

[0070] Furthermore, a second internal thread is provided in the third connecting channel 14, and an external thread matching the second internal thread is provided on the outer periphery of the pressure cylinder 43. After the first hydraulic connector 41 is connected to the second hydraulic connector 42, the operator threadably connects the pressure cylinder 43 to the third connecting channel 14 and limits the second hydraulic connector 42 by abutting the pressure cylinder 43 against the second hydraulic connector 42, thereby fixing the second hydraulic connector 42 in the third connecting channel 14.
