Description

Technical Field

[0001] This invention relates to the field of petroleum equipment technology, specifically to a safe oil drilling and production machine. Background Technology

[0002] Oil drilling and production equipment is a type of mechanical equipment used in oil extraction projects to perform deep drilling. This type of equipment includes tools such as oil drilling rigs, drill bits, and drill strings. Among them, drill bits are used in oil extraction projects to open wellheads on the surface and to excavate deep underground, and are an indispensable component of drilling and production equipment.

[0003] During oil extraction, as the drilling depth increases, the drill string needs to be removed and lengthened to meet the conditions for continued drilling.

[0004] Existing safe oil drilling rigs typically use bolts to secure the drill string during installation. However, during drilling operations, the high-speed rotation of the drill string causes vibrations, which can easily lead to loosening of the drill string. Therefore, there is a need to provide a safe oil drilling rig designed to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a safe oil drilling and production machine to solve the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A safe oil drilling rig, comprising:

[0008] A support tower on which drilling and production units are installed;

[0009] The lifting unit, installed on the support tower and connected to the drilling and production unit, is used to drive the drilling and production unit to move up and down.

[0010] A buffer unit, installed on the drilling and production unit, is used to buffer the drilling and production unit.

[0011] The rotating unit is installed on the drilling and production unit and connected to the buffer unit. It is used to drive the buffer unit to rotate under the action of the buffer unit.

[0012] The disassembly unit is installed on the drilling and production unit and is used for the installation and disassembly of the drilling and production unit.

[0013] The sliding unit is installed on the drilling and production unit. One end is connected to the rotating unit and the other end is connected to the disassembly unit. It is used to drive the disassembly unit to slide under the action of the rotating unit.

[0014] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0015] This invention includes a lifting unit installed on a support tower and connected to the drilling and production unit for lifting and lowering the drilling and production unit; a buffer unit installed on the drilling and production unit for buffering the drilling and production unit; a rotating unit installed on the drilling and production unit and connected to the buffer unit for rotating the buffer unit under the action of the buffer unit; a disassembly unit installed on the drilling and production unit for installing and disassembling the drilling and production unit; and a sliding unit installed on the drilling and production unit, with one end connected to the rotating unit and the other end connected to the disassembly unit for sliding the disassembly unit under the action of the rotating unit.

[0016] During oil extraction, a support tower is installed at the drilling site, and the hoisting and drilling units are activated. The hoisting unit lowers the drilling unit, facilitating drilling operations. As the drilling depth increases, the drill string needs to be lengthened. During the installation of the first and second drill strings, the second drill string is inserted into the end of the first drill string. A buffer unit cushions the drill string, improving its lifespan. The buffer unit rotates under the action of a rotating unit during sliding. This rotation, combined with the sliding unit, drives a disassembly unit to slide, allowing the first and second drill strings to engage and secure under the action of the disassembly unit. This allows for the installation and fixation of the drill string, thus extending its length.

[0017] During drilling, the buffer unit is continuously compressed due to the weight of the drill string. Furthermore, the disassembly unit remains engaged while the first drill string rotates clockwise, improving the stability of the drill string installation. This installation process simply involves threading one drill string through the end of another, enabling automatic installation with high stability, simplicity, and efficiency.

[0018] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] See Figures 1-6 A safe oil drilling rig, comprising:

[0029] Support tower 1, on which drilling and production unit 7 is installed;

[0030] The lifting unit 2 is installed on the support tower 1 and connected to the drilling and production unit 7, and is used to drive the drilling and production unit 7 to lift and lower.

[0031] Buffer unit 3 is installed on drilling and production unit 7 and is used to buffer drilling and production unit 7;

[0032] Rotating unit 4 is installed on drilling and production unit 7 and connected to buffer unit 3. It is used to drive buffer unit 3 to rotate under the action of buffer unit 3.

[0033] Disassembly unit 5 is installed on drilling and production unit 7 and is used for installing and disassembling drilling and production unit 7;

[0034] The sliding unit 6 is installed on the drilling and production unit 7. One end is connected to the rotating unit 4, and the other end is connected to the disassembly unit 5. It is used to drive the disassembly unit 5 to slide under the action of the rotating unit 4.

[0035] In an embodiment of the present invention, during oil extraction, by installing a support tower 1 at the oil drilling site, the hoisting unit 2 and the drilling unit 7 are activated. The hoisting unit 2 can drive the drilling unit 7 to descend, thereby facilitating drilling operations. As the drilling depth increases, the drill string length needs to be extended. When installing the first drill string 74 and the second drill string 75, the buffer unit 3 can buffer the drill string by inserting the second drill string 75 into the end of the first drill string 74, thus improving the service life of the drill string. The buffer unit 3 can rotate under the action of the rotating unit 4 during sliding. During the rotation, the buffer unit 3 can drive the disassembly unit 5 to slide through its connection with the sliding unit 6, so that the first drill string 74 and the second drill string 75 can be engaged and fixed under the action of the disassembly unit 5, thereby installing and fixing the drill string. This allows for the extension of the drill string. The installation process only requires inserting one drill string into the end of the other, thus achieving automatic installation of the drill string, with high stability after installation, and is simple and efficient.

[0036] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the lifting unit 2 includes:

[0037] A connecting frame 21 is fixed on the support tower 1, and a cylinder 22 is mounted on its surface;

[0038] A toothed disc 25 is mounted on the support tower 1 and has a chain 24 meshing with its surface. The end of the chain 24 is connected to the drilling and production unit 7.

[0039] Telescopic rod 23 is connected to the output end of cylinder 22, and the end of telescopic rod 23 is connected to the other end of chain 24.

[0040] In this embodiment, the connecting frame 21 is fixed on the support tower 1, and a cylinder 22 is mounted on its surface; the toothed plate 25 is mounted on the support tower 1, and a chain 24 is meshed with its surface, the end of the chain 24 is connected to the drilling unit 7; the telescopic rod 23 is connected to the output end of the cylinder 22, and the end of the telescopic rod 23 is connected to the other end of the chain 24.

[0041] Petroleum is a non-renewable resource, and its most fundamental characteristic is scarcity. Petroleum is the "lifeblood" of the modern economy and one of the most important energy sources today. During oil extraction, by installing a support tower 1 at the drilling site, and activating cylinder 22, the output of cylinder 22 controls the extension of telescopic rod 23. During the extension of telescopic rod 23, chain 24, under the pull of gravity from drilling unit 7, drives the toothed disc 25 to rotate counterclockwise on support tower 1, allowing drilling unit 7 to gradually descend and begin drilling operations.

[0042] The cylinder 22 and telescopic rod 23 in the lifting unit 2 can also be replaced by an electric telescopic rod, so that the chain 24 can drive the toothed disc 25 to rotate on the support tower 1 under the gravity of the drilling and production unit 7.

[0043] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the drilling and production unit 7 includes:

[0044] A fixed frame 71 is installed at the end of the chain 24, and a sliding frame 72 is fixed on the side. The sliding frame 72 is slidably connected to the support tower 1.

[0045] The drive component 73 is installed inside the mounting bracket 71;

[0046] The first drill string 74 is connected to the output end of the drive unit 73 and is connected to the second drill string 75 through the buffer unit 3;

[0047] Drill bit 76 is installed at the end of the second drill string 75.

[0048] In this embodiment, the fixed frame 71 is installed at the end of the chain 24, and a sliding frame 72 is fixed on the side. The sliding frame 72 is slidably connected to the support tower 1. The drive component 73 is installed inside the fixed frame 71. The first drill string 74 is connected to the output end of the drive component 73 and is connected to the second drill string 75 through the buffer unit 3. The drill bit 76 is installed at the end of the second drill string 75.

[0049] When the drive unit 73 is activated, the output end of the drive unit 73 can drive the first drill string 74 to rotate. The first drill string 74 can drive the second drill string 75 to rotate synchronously through the buffer unit 3. Thus, the second drill string 75 can drive the drill bit 76 at its end to rotate synchronously, thereby facilitating the drilling operation of the drill bit 76.

[0050] When the drive component 73 is raised or lowered, it can drive the sliding frame 72 to slide synchronously on the side of the support tower 1 through the fixed frame 71. When the drive component 73 is activated, the support tower 1 can limit the fixed frame 71 through the sliding frame 72, thereby limiting the drive component 73 and improving the stability of the drive component 73 during operation.

[0051] The driving component 73 can be an electric motor or a pneumatic motor, which can easily drive the first drill string 74 to rotate stably.

[0052] In one embodiment of the present invention, such as Figure 3 As shown, the buffer unit 3 includes:

[0053] Groove 31 is formed at the end of the first drill string 74;

[0054] The groove 32 is formed at the end of the second drill string 75, and a slide rod 33 is slidably connected inside it;

[0055] The disc 35 is fixed to the end of the slide bar 33 and slidably connected to the groove 31;

[0056] The elastic element 34 is connected between the ends of the disk 35 and the second drill string 75.

[0057] In this embodiment, the groove 31 is formed at the end of the first drill string 74; the slide groove 32 is formed at the end of the second drill string 75, and a slide rod 33 is slidably connected inside; the disc 35 is fixed at the end of the slide rod 33 and slidably connected to the groove 31; the elastic member 34 is connected between the ends of the disc 35 and the second drill string 75.

[0058] As the drilling depth increases, the drill string length needs to be extended. At this point, cylinder 22 is activated, exposing the first drill string 74 and the second drill string 75 to the surface. By rotating the second drill string 75, it is removed from the bottom of the first drill string 74. The third drill string is then removed and installed between the first and second drill strings 74 and 75. The installation process for the third drill string is the same as the installation process between the first and second drill strings 74 and 75. For ease of description, the installation process between the first and second drill strings 74 and 75 will be explained first.

[0059] When installing the first drill string 74 and the second drill string 75, the second drill string 75 is inserted into the groove 31. During the process of the second drill string 75 entering the groove 31, it can drive the slide rod 33 and the disc 35 to slide into the groove 31.

[0060] Until the disc 35 contacts the inner wall of the groove 31, the disc 35 can push the slide rod 33 downward in the slide groove 32 under the action of the gravity of the first drill string 74. The disc 35 can compress the elastic element 34. In this way, the elastic element 34 can buffer the first drill string 74 through the disc 35, preventing hard collisions during the installation of the first drill string 74 and the second drill string 75, and improving the service life of the first drill string 74 and the second drill string 75.

[0061] The elastic element 34 can be a spring or elastic rubber, which can be used to buffer the first drill string 74 through the disc 35.

[0062] In one embodiment of the present invention, such as Figure 3 and Figure 6 As shown, the rotating unit 4 includes:

[0063] The fixed cylinder 41 is installed in the groove 31 and is slidably connected to the slide rod 33;

[0064] The arc-shaped groove 42 is formed on the surface of the fixed cylinder 41;

[0065] The sliding column 43 is fixed to the side of the sliding rod 33 and is slidably connected to the arc-shaped groove 42.

[0066] In this embodiment, the fixed cylinder 41 is installed in the groove 31 and is slidably connected to the slide rod 33; the arc-shaped groove 42 is formed on the surface of the fixed cylinder 41; the sliding column 43 is fixed to the side of the slide rod 33 and is slidably connected to the arc-shaped groove 42.

[0067] When the slide rod 33 slides downward in the slide groove 32, the slide rod 33 can drive the sliding column 43 on its side to slide synchronously. Since the sliding column 43 and the arc groove 42 are slidably connected, the slide rod 33 can rotate in the slide groove 32 under the action of the sliding column 43 and the arc groove 42, so that the slide rod 33 can drive the disc 35 at its end to rotate synchronously.

[0068] During the rotation of the disc 35, the sliding unit 6 can drive the disassembly unit 5 to slide, so that the disassembly unit 5 can limit the first drill string 74 and the second drill string 75, thereby allowing the first drill string 74 and the second drill string 75 to be installed and fixed.

[0069] Rolling wheels can be installed on the surface of the sliding column 43 in the rotating unit 4. The rolling wheels and the arc groove 42 are connected by a rolling connection, thereby improving the smoothness of the sliding column 43 sliding in the arc groove 42.

[0070] In one embodiment of the present invention, such as Figure 4 As shown, the disassembly unit 5 includes:

[0071] The connecting cylinder 51 is fixed to the end of the second drill string 75 and has a recessed hole 52 inside.

[0072] The limiting component 53 is slidably connected within the recessed hole 52;

[0073] The limiting groove 54 is formed in the groove 31 and is slidably connected to the limiting member 53.

[0074] In this embodiment, the connecting cylinder 51 is fixed to the end of the second drill string 75 and has a recessed hole 52 inside; the limiting member 53 is slidably connected in the recessed hole 52; the limiting groove 54 is opened in the groove 31 and is slidably connected to the limiting member 53.

[0075] During rotation, the disc 35 drives the sliding unit 6 to slide outward within the recess 52. As the sliding unit 6 slides, it pushes the limiting member 53 outward within the recess 52 until the limiting member 53 slides into the limiting groove 54. This allows the first drill string 74 and the second drill string 75 to be positioned by the limiting groove 54 and the limiting member 53, thus facilitating their installation. When the first drill string 74 rotates, it can drive the second drill string 75 to rotate synchronously through the limiting groove 54 and the limiting member 53, thereby enabling oil drilling and extraction.

[0076] Multiple sets of limiting components 53 and limiting grooves 54 in the disassembly unit 5 can be set, thereby improving the stability of the installation of the first drill string 74 and the second drill string 75.

[0077] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the sliding unit 6 includes:

[0078] Inclined groove 61 is formed on disc 35;

[0079] The sliding rod 62 is slidably connected at both ends to the inclined groove 61 and the concave hole 52, respectively.

[0080] The slider 64 is slidably connected inside the recess 52 and is connected inside the recess 52 via the airbag 63. Its side is slidably connected to the sliding rod 62.

[0081] In this embodiment, the inclined groove 61 is formed on the disk 35; the two ends of the sliding rod 62 are slidably connected to the inclined groove 61 and the concave hole 52 respectively; the slider 64 is slidably connected to the concave hole 52, and is connected to the concave hole 52 through the airbag 63, and is slidably connected to the sliding rod 62 on its side.

[0082] When the slide rod 33 rotates in the slide groove 32 under the action of the rotating unit 4, the slide rod 33 can drive the disk 35 to rotate synchronously. When the disk 35 rotates clockwise, the disk 35 can drive the inclined groove 61 to rotate synchronously. Since the inclined groove 61 and the slide rod 62 are slidably connected, the slide rod 62 can slide outward in the concave hole 52 under the action of the inclined groove 61. When the slide rod 62 slides outward, it can push the limiting member 53 to slide synchronously until the limiting member 53 slides into the limiting groove 54.

[0083] This allows the first drill string 74 and the second drill string 75 to be limited by the action of the limiting groove 54 and the limiting member 53, thus enabling the installation of the first drill string 74 and the second drill string 75. When the first drill string 74 rotates, it can drive the second drill string 75 to rotate synchronously through the limiting groove 54 and the limiting member 53, thereby performing oil drilling and extraction.

[0084] When the sliding rod 62 slides downward, it can push the slider 64 to compress the airbag 63. In addition, when the sliding rod 62 slides outward in the concave hole 52, it can also slide outward on the surface of the slider 64.

[0085] The sliding unit 6 may also employ a circular groove 611, which is formed on the disk 35 and is connected to the inclined groove 61. The circular groove 611 and the disk 35 are concentric circles. Therefore, when the sliding rod 62 slides outward in the concave hole 52 under the action of the inclined groove 61, the sliding rod 62 can also slide synchronously in the inclined groove 61 until the sliding rod 62 slides into the circular groove 611. Thus, the sliding rod 62 can limit the limiting member 53 under the action of the circular groove 611, so that the limiting member 53 can be stably engaged in the limiting groove 54, thereby improving the stability of the installation between the first drill string 74 and the second drill string 75.

[0086] Similarly, when disassembling the first drill string 74 and the second drill string 75, simply rotate the second drill string 75 in the opposite direction so that the disc 35 rotates counterclockwise. This causes the sliding rod 62 to slide inward in the concave hole 52 under the action of the inclined groove 61, so that the limiting member 53 slides out of the limiting groove 54.

[0087] The process of installing the third drill string on the first drill string 74 and the second drill string 75 is the same as the installation process between the first drill string 74 and the second drill string 75, and will not be described in detail here. Therefore, the third drill string can be installed through the above process, thereby lengthening the drill string.

[0088] During drilling, the buffer unit 3 is continuously compressed due to the weight of the drill string itself. Furthermore, the disassembly unit 5 remains engaged while the first drill string rotates clockwise, improving the stability of the drill string installation. This installation process simply involves threading one drill string through the end of another, enabling automatic installation with high stability, simplicity, and efficiency.

[0089] The working principle of this invention is as follows: During the oil extraction process, by installing the support tower 1 at the oil drilling site, the cylinder 22 is activated. The output end of the cylinder 22 can control the extension rod 23 to extend. During the extension of the extension rod 23, the chain 24 can drive the toothed disc 25 to rotate counterclockwise on the support tower 1 under the gravity pull of the drilling unit 7, so that the drilling unit 7 can gradually descend, activate the drilling unit 7, and enable the drilling unit 7 to perform drilling operations.

[0090] As drilling depth increases, the drill string length needs to be extended. During installation of the first drill string 74 and the second drill string 75, the second drill string 75 is inserted into the groove 31. As it enters the groove 31, the sliding rod 33 and the disc 35 slide into the groove 31. The disc 35 continues until it contacts the inner wall of the groove 31. Upon contact, the disc 35, under the weight of the first drill string 74, pushes the sliding rod 33 downwards within the groove 32. The disc 35 compresses the elastic element 34. This allows the elastic element 34 to cushion the first drill string 74 through the disc 35, preventing hard collisions during installation and improving the service life of the first and second drill strings 74 and 75.

[0091] When the slide rod 33 slides downward in the slide groove 32, the slide rod 33 can drive the sliding column 43 on its side to slide synchronously. Since the sliding column 43 and the arc groove 42 are slidably connected, the slide rod 33 can rotate in the slide groove 32 under the action of the sliding column 43 and the arc groove 42, so that the slide rod 33 can drive the disc 35 at its end to rotate synchronously.

[0092] When the disc 35 rotates clockwise, it drives the inclined groove 61 to rotate synchronously. Since the inclined groove 61 and the sliding rod 62 are slidably connected, the sliding rod 62 can slide outward within the recess 52 under the action of the inclined groove 61. As the sliding rod 62 slides outward, it pushes the limiting member 53 to slide synchronously until the limiting member 53 slides into the limiting groove 54. This allows the first drill string 74 and the second drill string 75 to be limited by the limiting groove 54 and the limiting member 53, thus enabling the installation of the first drill string 74 and the second drill string 75. When the first drill string 74 rotates, it can drive the second drill string 75 to rotate synchronously through the limiting groove 54 and the limiting member 53, thereby performing oil drilling and extraction.

[0093] The process of installing the third drill string on the first drill string 74 and the second drill string 75 is the same as the installation process between the first drill string 74 and the second drill string 75, and will not be described in detail here. Therefore, the third drill string can be installed through the above working process, thereby lengthening the drill string. This installation process only requires one drill string to be inserted through the end of another drill string, thus achieving automatic installation of the drill string, and the installation is highly stable, simple and efficient.
