Description

Technical Field

[0001] This utility model relates to the technical field of drill pipes, and more particularly to a common drill pipe with communication function. Background Technology

[0002] Conventional drill pipes are commonly used in directional drilling. They achieve drilling by transmitting torque and axial force, reaching depths of approximately 200 meters. The overall drilling method is rotary drilling, and conventional drill pipes have high torsional strength. However, compared to cable-operated drill pipes, conventional drill pipes typically lack signal transmission capabilities.

[0003] Cable-through drill pipe is extremely expensive, with a purchase price 5 to 10 times, or even higher, than that of ordinary drill pipe. For companies with tight budgets or a small number of wells, this represents a huge investment. A common approach is to modify ordinary drill pipe by adding a cable core, thus converting it into a cable-through drill pipe. This modification requires not only securing the cable core but also maintaining the connection strength of the drill pipe's threaded joints to preserve torque transmission and drilling fluid delivery capabilities. Currently, no practically feasible modification solution has been developed in the industry to address this need. Utility Model Content

[0004] Therefore, it is necessary to provide a standard drill pipe with communication capabilities to solve the problem of the difficulty in modifying standard drill pipes.

[0005] To achieve the above objectives, the inventors provide a standard drill pipe with communication functionality, comprising:

[0006] The drill pipe body has a first body connector and a second body connector at each end;

[0007] A communication component inserted within the drill pipe body includes an insulating tube, a conductive post, a first insulating positioning element, a second insulating positioning element, a first conductive connector, and a second conductive connector. The insulating tube is fitted inside the drill pipe body, and the conductive post is fitted inside the insulating tube. The first conductive connector passes through the first insulating positioning element and is screwed to one end of the conductive post. The second conductive connector passes through the second insulating positioning element and is screwed to the other end of the conductive post, such that the first insulating positioning element and the second insulating positioning element are respectively engaged within the first body connector and the second body connector. One of the first insulating positioning elements and the second insulating positioning element has a limiting part on its outer wall to restrict its rotation relative to the drill pipe body. The first insulating positioning element and the second insulating positioning element support the outer wall of the insulating tube to form a fluid channel with the inner wall of the drill pipe body.

[0008] When the first body connector and the second body connector of a different ordinary drill pipe are adapted and sealed together, the first conductive connector and the second conductive connector are adapted and connected together.

[0009] Furthermore, the outer wall of the first insulating positioning member is provided with a limiting part, and the second insulating positioning member and / or the second conductive connector are provided with a screwing structure;

[0010] Alternatively, the outer wall of the second insulating positioning member may be provided with a limiting part, and the first insulating positioning member and / or the first conductive connector may be provided with a screwing structure.

[0011] Furthermore, the first conductive connector is a female connector, the second conductive connector is a male connector, the first body connector is a male connector, and the second body connector is a female connector.

[0012] Furthermore, the end faces of the first insulating positioning member and the first conductive connector facing outwards from the drill rod body are flush with the end face of the first body connector, and the second insulating positioning member and the second conductive connector are recessed into the second body connector.

[0013] Furthermore, the first conductive connector and the first insulating positioning element are an integral structure.

[0014] Furthermore, the second conductive connector and the second insulating positioning element are an integral structure.

[0015] Furthermore, when the outer wall of the first insulating positioning member is provided with a limiting part, the inner wall of the first body connector is provided with a limiting groove adapted to the limiting part; when the outer wall of the second insulating positioning member is provided with a limiting part, the inner wall of the second body connector is provided with a limiting groove adapted to the limiting part.

[0016] Furthermore, the limiting portion is symmetrically disposed on the outer wall of the first insulating positioning member or the outer wall of the second insulating positioning member; the number of limiting grooves is the same as the number of limiting portions.

[0017] Furthermore, the first insulating positioning member includes an inner insulating positioning member ring, an outer insulating positioning member ring, and a connecting piece, wherein the inner insulating positioning member ring and the outer insulating positioning member ring are connected at intervals by the connecting piece; the second insulating positioning member has the same structure as the first insulating positioning member.

[0018] Furthermore, a first insulating washer is provided between the insulating tube and the first insulating positioning member, and a second insulating washer is provided between the insulating tube and the second insulating positioning member.

[0019] Unlike existing technologies, the above technical solution has the following advantages: In this application, a fluid channel is formed by supporting the first and second insulating positioning components. These components, together with the insulating tube, isolate the fluid channel from the conductive column, the first conductive connector, and the second conductive connector, preventing contact between the conductive parts within the communication component and the liquid in the fluid channel. Furthermore, a limiting part is provided on the outer wall of the first or second insulating positioning component to prevent relative rotation between the communication component and the drill rod body during use. This application achieves the communication function of a common drill rod through a simple structure and can be directly modified from existing common drill rods, resulting in a high degree of modification feasibility.

[0056] Please see Figure 1-8 This embodiment of a common drill pipe with communication function includes:

[0057] The drill pipe body 11 has a first body connector 12 and a second body connector 13 at its two ends respectively;

[0058] The communication component, which is installed within the drill pipe body 11, includes an insulating tube 21, a conductive post 22, a first insulating positioning element 23, a second insulating positioning element 24, a first conductive connector 25, and a second conductive connector 26. The insulating tube 21 is fitted inside the drill pipe body 11, the conductive post 22 is fitted inside the insulating tube 21, the first conductive connector 25 passes through the first insulating positioning element 23 and is screwed to one end of the conductive post 22, and the second conductive connector 26 passes through the second insulating positioning element 24 and... The first insulating positioning member 23 and the second insulating positioning member 24 are screwed onto the other end of the conductive post 22, so that the first insulating positioning member 23 and the second insulating positioning member 24 are respectively locked into the first body connector 12 and the second body connector 13. One of the first insulating positioning member 23 and the second insulating positioning member 24 is provided with a limiting part 271 on its outer wall to restrict its rotation relative to the drill rod body 11. The first insulating positioning member 23 and the second insulating positioning member 24 support the outer wall of the insulating tube 21 and the inner wall of the drill rod body 11 to form a fluid channel 3.

[0059] When the first body connector 12 and the second body connector 13 of a different ordinary drill pipe are adapted and sealed together, the first conductive connector 25 and the second conductive connector 26 are adapted and connected together.

[0060] The cross-sections of the first body connector 12, the second body connector 13, the first conductive connector 25, and the second conductive connector 26 are configured to be circular, so that when the first body connector 12 and the second body connector 13 are screwed together, the first conductive connector 25 and the second conductive connector 26 can rotate relative to each other.

[0061] The first body connector 12 and the second body connector 13 are fixed to the drill pipe body 11 by welding.

[0062] The insulating tube 21, the first insulating positioning element 23, and the second insulating positioning element 24 are made of insulating material, specifically plastic. The first conductive connector 25 and the second conductive connector 26 of the conductive post 22 are made of metal material, specifically copper or other alloys. The position of the insulating tube 21 within the drill pipe body 11 is fixed by the first insulating positioning element 23 and the second insulating positioning element 24 to prevent the insulating tube 21 from wobbling in the axial and radial directions within the drill pipe body 11. The insulating tube 21, the first insulating positioning element 23, and the second insulating positioning element 24 isolate the fluid channel 3 from the conductive post 22, the first conductive connector 25, and the second conductive connector 26, preventing short circuits caused by contact between the liquid in the fluid channel 3 and the conductive post 22 during drill pipe drilling.

[0063] Both the inner walls of the first body connector 12 and the second body connector 13 are provided with stepped structures. The first insulating positioning member 23 is inserted into the first body connector 12 from the outside. The first insulating positioning member 23 is locked in the axial direction by the stepped structure and will not continue to move into the drill pipe body 11. When the first conductive connector 25 and the conductive post 22 are connected, the first insulating positioning member 23 will be further fixed to prevent the first insulating positioning member 23 from detaching from the end of the first body connector 12 (i.e., the end of the first body connector 12 away from the drill pipe body 11). The second insulating positioning member 24 is inserted into the second body connector 13 from the outside. The second insulating positioning member 24 is locked in the axial direction by the stepped structure and will not continue to move into the drill pipe body 11. When the second conductive connector 26 and the conductive post 22 are connected, the second insulating positioning member 24 will be further fixed to prevent the second insulating positioning member 24 from detaching from the end of the second body connector 13 (i.e., the end of the second body connector 13 away from the drill pipe body 11).

[0064] To prevent the communication component from rotating within the drill pipe body 11 during drilling, a limiting part 271 is provided in one of the first insulating positioning member 23 and the second insulating positioning member 24. The limiting part 271 restricts the position of the communication component within the drill pipe body 11, preventing rotation. The end without the limiting part 271 can meet the requirements for threaded fixing.

[0065] The limiting part 271 can specifically be a semi-cylindrical structure protruding from its surface. The limiting part 271 extends a certain length from one end face of the first insulating positioning member 23, and the extension length of the limiting part 271 is less than the length of the first insulating positioning member 23. Alternatively, the limiting part 271 extends a certain length from one end face of the second insulating positioning member 24, and the extension length of the limiting part 271 is less than the length of the second insulating positioning member 24. In addition to a cylindrical structure with a semi-circular cross-section, it can also be a cylindrical structure with a triangular or square cross-section. Of course, in some embodiments, the limiting part 271 can also be a protrusion located in the middle of the outer wall of the insulating positioning member. That is, the limiting part 271 only needs to be able to restrict the relative rotation between the insulating positioning member and the drill rod body 11.

[0066] The adaptation connection between the first body connector 12 and the second body connector 13 of different ordinary drill pipes means that the end of the first body connector 12 of one ordinary drill pipe away from the drill pipe body 11 can be adapted to connect with the end of the second body connector 13 of another ordinary drill pipe away from the drill pipe body 11, thereby extending the length of the ordinary drill pipe and achieving the purpose of use. When the first body connector 12 and the second body connector 13 are usually threaded, after they are screwed in place, the end of the first conductive connector 25 away from the conductive post 22 adapts to connect with the end of the second conductive connector 26 away from the conductive post 22, realizing the internal circuit connection of multiple ordinary drill pipes.

[0067] The first body connector 12 and the second body connector 13 are generally designed as a screw-in male and female connector structure, while the first conductive connector 25 and the second conductive connector 26 are usually designed as a plug-in male and female connector structure. During the process of screwing the first body connector 12 and the second body connector 13, the first conductive connector 25 gradually adapts to the second conductive connector 26; conversely, when the first body connector 12 and the second body connector 13 are disassembled, the first conductive connector 25 also gradually separates from the second conductive connector 26.

[0068] In this application, the first insulating positioning member 23 and the second insulating positioning member 24 are used to support and form the fluid channel 3. These components, together with the insulating tube 21, isolate the fluid channel 3 from the conductive post 22, the first conductive connector 25, and the second conductive connector 26, preventing contact between the conductive parts within the communication component and the liquid within the fluid channel 3. Furthermore, a limiting part 271 is provided on the outer wall of the first insulating positioning member 23 or the second insulating positioning member 24 to prevent relative rotation between the communication component and the drill rod body 11 during drill rod use. This application achieves the communication function of a common drill rod through a simple structure and can be directly modified from existing common drill rods, resulting in a high degree of modification feasibility.

[0069] In some embodiments, the outer wall of the first insulating positioning member 23 is provided with a limiting portion 271, and the second insulating positioning member 24 and / or the second conductive connector 26 are provided with a screwing structure.

[0070] Alternatively, a limiting portion 271 may be provided on the outer wall of the second insulating positioning member 24, and a screwing structure may be provided on the first insulating positioning member 23 and / or the first conductive connector 25.

[0071] When the limiting part 271 is provided on the outer wall of the first insulating positioning member 23, the limiting part 271 will allow the first insulating positioning member 23 to rotate relative to the first body connector 12. In this case, in order to facilitate the screwing work inside the drill rod body 11, a screwing structure is provided on the second insulating positioning member 24 and / or the second conductive connector 26 at the other end, so as to screw the second conductive connector 26 onto the conductive post 22. The screwing structure provided on the second insulating positioning member 24 and / or the second conductive connector 26 means that the screwing structure is provided on the side of the second insulating positioning member 24 facing the outside of the second body connector 13, or the screwing structure is provided on the side of the second conductive connector 26 facing the outside of the second body connector 13, or both the second insulating positioning member 24 and the second conductive connector 26 are provided with screwing structures on the side facing the outside of the second body connector 13. Similarly, the outer wall of the second insulating positioning member 24 is provided with a limiting part 271, and the first insulating positioning member 23 and / or the first conductive connector 25 are provided with a screwing structure, which has a similar effect, and will not be described in detail here.

[0072] Taking the limiting part 271 on the outer wall of the first insulating positioning member 23 as an example, during installation, the conductive post 22 is inserted into the insulating tube 21, and the first conductive connector 25 is passed through the first insulating positioning member 23 and screwed onto one end of the conductive post 22. The pre-assembled component is then inserted into the drill rod body 11 from one end of the first body connector 12. The first insulating positioning member 23 abuts against the step of the drill rod body 11. The second conductive connector 26 is passed through the second insulating positioning member 24 and screwed onto the other end of the conductive post 22. The second insulating positioning member 24 also has a corresponding abutting step inside the drill rod body 11. After the second conductive connector 26 is screwed into place or the second insulating positioning member 24 abuts, the pre-assembled component is tightened and will not detach from the drill rod body 11. This structure is convenient and efficient to install.

[0073] like Figure 1-4As shown, in some embodiments, the first conductive connector 25 is a female connector, the second conductive connector 26 is a male connector, the first body connector 12 is a male connector, and the second body connector 13 is a female connector. The alternating male and female design of the first conductive connector 25 and the first body connector 12 improves structural compactness and facilitates obtaining a larger fluid channel 3. Similarly, the alternating male and female design of the second conductive connector 26 and the second body connector 13 improves structural compactness and facilitates obtaining a larger fluid channel 3. A sealing ring 14 is embedded in the inner wall of the second body connector 13. When the first body connector 12 is inserted into the second body connector 13, the sealing ring 14 seals the two. Specifically, the sealing ring 14 is located at the end of the second body connector 13 facing the drill pipe body 11. The sealing ring 14 is positioned opposite the end of the second conductive connector 26.

[0074] like Figure 1 As shown, in some embodiments, the end faces of the first insulating positioning member 23 and the first conductive connector 25 facing outwards from the drill rod body 11 are flush with the end face of the first body connector 12, and the second insulating positioning member 24 and the second conductive connector 26 are recessed within the second body connector 13. Placing the end faces of the first insulating positioning member 23 and the first conductive connector 25 facing outwards from the drill rod body 11 flush with the end face of the first body connector 12 away from the drill rod body prevents damage to the first or second insulating positioning member after the first and second body connectors are threaded together. In embodiments where the second conductive connector is a male connector, the second conductive connector needs to be recessed within the second body connector to protect its structure and facilitate transportation and storage.

[0075] like Figure 5-6 As shown, in some embodiments, the first conductive connector 25 and the first insulating positioning member 23 are an integral structure. The first conductive connector 25 and the first insulating positioning member 23 are inserts, with the metal first conductive connector 25 embedded in the plastic first insulating positioning member 23, which facilitates one-time installation and also avoids gaps between the two to prevent shaking.

[0076] like Figure 7 As shown, in some embodiments, the second conductive connector 26 and the second insulating positioning member 24 are an integral structure. The second conductive connector 26 and the second insulating positioning member 24 are inserts, with the metal second conductive connector 26 embedded in the plastic second insulating positioning member 24, which facilitates one-time installation and also avoids the gap between the two to prevent shaking.

[0077] like Figure 5-6As shown, in some embodiments, when the outer wall of the first insulating positioning member 23 is provided with a limiting portion 271, the inner wall of the first body connector 12 is provided with a limiting groove 272 adapted to the limiting portion 271; when the outer wall of the second insulating positioning member 24 is provided with a limiting portion 271, the inner wall of the second body connector 13 is provided with a limiting groove 272 adapted to the limiting portion 271. Taking the outer wall of the first insulating positioning member 23 being provided with a limiting portion 271 as an example, the limiting groove 272 has a limiting function in two dimensions. After the limiting portion 271 is engaged in the limiting groove 272, the limiting groove 272 can prevent the first insulating positioning member 23 from rotating within the first body connector 12. The bottom of the limiting groove 272 (i.e., the side of the limiting groove 272 facing the drill rod body 11) is an abutment surface, which can limit the insertion depth of the limiting portion 271. Similarly, if the second insulating positioning member 24 is provided with fiber cloth, the limiting groove 272 in the second body connector 13 is also like this.

[0078] like Figure 3 As shown, in some embodiments, the limiting portions 271 are symmetrically arranged on the outer wall of the first insulating positioning member 23 or the outer wall of the second insulating positioning member 24; the number of limiting grooves 272 is the same as the number of limiting portions 271. The symmetrically arranged limiting portions 271 can better prevent rotation and stop the first insulating positioning member 23 and the first body connector 12 (or the second insulating positioning member 24 and the second body connector 13).

[0079] like Figure 5-6 As shown, in some embodiments, the first insulating positioning member 23 includes an inner insulating positioning member 231, an outer insulating positioning member 232, and a connecting piece 233, wherein the inner insulating positioning member 231 and the outer insulating positioning member 232 are connected at intervals by the connecting piece 233; the second insulating positioning member 24 has the same structure as the first insulating positioning member 23.

[0080] The inner ring of the first insulating positioning member 23 has an annular columnar structure, and the first conductive connector 25 is sleeved inside its inner ring. The outer wall of the outer ring is used to mate with the first body connector 12. Similarly, the structure of the second insulating positioning member 24 is the same as that of the first insulating positioning member 23.

[0081] Taking the first insulating positioning member 23 as an example, the inner ring and outer ring of the positioning member have the same height, and the outer wall of the inner ring and the inner wall of the outer ring are equidistantly arranged. After the first insulating positioning member 23 and the second insulating positioning member 24 are installed, the distance between the inner ring and the outer ring determines the cross-sectional size of the fluid channel 3. Preferably, two connecting pieces 233 or connecting posts are symmetrically arranged between the inner ring and the outer ring of the positioning member, so that the inner ring and the outer ring of the positioning member form a stable connection relationship, while having a larger cross-section of the fluid channel 3. In the embodiment, the connecting piece 233 refers to a thin strip structure that is longitudinally arranged between the inner ring and the outer ring of the positioning member, which can occupy less fluid channel 3 size. In the embodiment, the connecting post refers to a columnar structure with a circular, square, elliptical or other shapes.

[0082] like Figure 3 , Figure 5-6 As shown, in this embodiment, when screwing the first insulating positioning member 23, the screwing tool can be directly placed on the connecting piece 233 for screwing, without the need for other screwing structures on the first insulating positioning member 23. Of course, in embodiments where the first insulating positioning member 23 and the first conductive connector 25 are integrally formed, the first conductive connector 25 also does not need to have an additional screwing structure.

[0083] like Figure 1-2 , Figure 8 As shown, in some embodiments, a first insulating washer 28 is provided between the insulating tube 21 and the first insulating positioning member 23, and a second insulating washer 29 is provided between the insulating tube 21 and the second insulating positioning member 24. The first insulating washer 28 and the second insulating washer 29 can be made of silicone or rubber, achieving both insulation and sealing. After the first conductive connector 25 is passed through the first insulating positioning member 23 and screwed onto the conductive post 22, the first insulating positioning member 23 presses against the first insulating washer 28, sealing that position. Similarly, after the second conductive connector 26 is passed through the second insulating positioning member 24 and screwed onto the conductive post 22, the second insulating positioning member 24 presses against the second insulating washer 29, sealing that position. The first insulating washer 28 and the second insulating washer 29 also prevent liquid in the fluid channel 3 from flowing into the fluid channel 3 from the gap between the insulating tube 21 and the first insulating positioning member 23, or from flowing into the fluid channel 3 from the gap between the insulating tube 21 and the second insulating positioning member 24.

[0084] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
