Technical Field

[0001] The invention relates to the technical field of oil extraction, in particular to oil drilling equipment with an anti-deviation mechanism and a method thereof. Background Art

[0002] Oil extraction is to dig and extract oil from places where oil is stored. In the process of oil extraction, oil and gas wells are usually used to make the oil and gas in the storage layer flow into it, so as to facilitate the extraction. Therefore, before oil extraction, it is necessary to dig the places where oil is stored to form oil and gas wells, so oil drilling rigs are needed to complete the excavation of oil and gas wells. Drilling is a method of finding oil and gas fields by drilling. Drilling refers to drilling holes in the formation with a drilling rig, and soil samples can be taken along the depth of the hole. When using a drill rod for drilling, the stability is low, and the drill rod is very easy to swing in the hole. With the different composition materials of the rock, the drill rod will have serious position deviation during the drilling process; The existing device cannot provide good protection for the drill rod and cannot accurately correct its deviation during the drilling process, which results in the drill bit being unable to directly penetrate the detection point, and the quality and efficiency of drilling are greatly affected.

[0005] Furthermore, the correction assembly includes a rack, a through hole, a rotating shaft, a gear, a limit bar, a connecting shaft and a rectangular ring; the outer surface of the connecting cylinder is fixedly connected to a rack at a position below the damper, and the rack corresponds to the cavity, a through hole is opened at a position on the inner surface of the cavity corresponding to the rack, and the rack passes through the through hole and extends to the inside of the cavity, one side of the inner surface of the cavity is rotatably connected to a rotating shaft, and one end of the rotating shaft is rotatably connected to the cavity, and the other end is fixedly connected to a gear, the rack is located above the corresponding gear and meshes with it, the outer surfaces on both sides of the rack are fixedly connected to limit bars, and limit grooves are opened at positions corresponding to the through holes and limit bars, and the limit bars and limit grooves are matched with each other and movably connected.

[0006] Furthermore, a connecting shaft is fixedly connected to a position near the edge of the outer surface of the gear away from the rotating shaft, and a rectangular ring is movably connected to the outer surface of the connecting shaft, one end of the connecting shaft away from the gear passes through the rectangular ring and is fixedly connected to a limiting block, a connecting column is fixedly connected to the outer surface of one side of the rectangular ring, one end of the connecting column is fixedly connected to the rectangular ring, and the other end passes through the outside of the cavity and is fixedly connected to an adjustment component, and the connecting column is movably connected to the cavity.

[0007] Furthermore, the adjustment assembly includes a movable ring, balls, a movable cavity, a fixed rod, a piston plate and a damping spring shock absorber; one end of the connecting column passes through the interior of the fixed cylinder and is fixedly connected to the movable ring, and the drill rod body passes through the movable ring, the inner surface of the movable ring is annular and equidistantly embedded with four groups of balls in a rolling connection, and a movable cavity is opened at one end of the movable ring away from the connecting column, a fixed rod is fixedly connected to the position of the inner surface of the fixed cylinder corresponding to the movable cavity, and one end of the fixed rod is fixedly connected to the fixed cylinder, and the other end passes through the interior of the movable cavity and is movably connected to it.

[0009] Further, the operating method of the oil drilling equipment comprises the following steps: Step 1: Before drilling, first install the fixed tube in the area to be drilled through bolts, then make the bottom end of the drill pipe body pass through the fixed tube and the movable ring, and connect the upper end with the external driving device, then turn on the external driving device to drive the drill pipe body to drive the drill bit to drill, so that the drill bit drills into the ground to work; Step 2: When the drill rod body deviates to one side and contacts the steel ball during rotation, the connecting tube located in the inclination direction of the drill rod body is squeezed by the steel ball to squeeze the spring 1 and the damper along the direction of the limit column. Therefore, the spring 1 and the damper can be used to apply a driving force to the connecting tube to keep moving in the vertical direction, so that the inclination amplitude of the drill rod body can be buffered and adjusted. Step 3: When the connecting tube is pushed by the drill rod body to move in the direction of the extrusion spring, the rack moves toward the inside of the cavity along the through hole, so the gear rotates under the drive of the rack, and the connecting shaft drives the rectangular ring on its surface to move toward the inner wall of the fixed tube. The movable ring moves toward the drill rod body under the push of the connecting column, and the ball contacts the drill rod body and pushes the drill rod body to move in the direction to keep itself vertical. Therefore, when the drill rod body deviates, it can be corrected in time, so that the drill rod body can be kept vertical as a whole during the downward exploration process, avoiding damage to the drill rod body due to uneven force caused by deviation. Step 4. During the movement of the drill pipe body to maintain the vertical direction, the connecting tube pushes the steel ball under the action of spring 1 to always fit the drill pipe body, thereby driving the rack to drive the gear to rotate, and the movable ring returns to its original state under the joint action of the damping spring shock absorber and the connecting column. During the movement of the movable ring along the fixed rod, the piston plate and the movable cavity move relative to each other, and the air around the movable ring enters and is discharged from the movable cavity through the air guide hole, which accelerates the rate at which the heat generated during the friction between the ball and the drill pipe body is dissipated outwards, thereby reducing friction loss.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by providing a buffer, when the drill rod body deviates to one side and contacts the steel ball during rotation, the connecting tube located in the inclination direction of the drill rod body is squeezed by the steel ball to squeeze the spring 1 and the damper along the direction of the limit column, so that the spring 1 and the damper can be used to apply a driving force to the connecting tube to keep moving in the vertical direction, so that the inclination amplitude of the drill rod body can be buffered and adjusted, and the deviation angle of the drill rod during the process can be reduced; In the present invention, by arranging the deviation correction component and the adjustment component, when the drill rod body is tilted to drive the connecting tube to move in the direction of the extrusion spring, the rack moves toward the inside of the cavity along the through hole, so the gear rotates under the drive of the rack, and the connecting shaft drives the rectangular ring on its surface to move in the direction close to the inner wall of the fixed tube, and the movable ring moves in the direction close to the drill rod body under the push of the connecting column, and the ball contacts the drill rod body and pushes the drill rod body to move in the direction to keep itself vertical. By arranging four groups of deviation correction components and adjustment components at four positions of the drill rod body, the drill rod body can be corrected in multiple directions when it is offset, so that the drill rod body can be kept vertical as a whole during the downward exploration process, and the drill rod body can be prevented from being damaged due to uneven force due to the offset, and the drill rod body can be corrected in multiple directions to prevent it from being offset to a large extent during the drilling process and affecting the drilling accuracy.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The base 3 is fixedly connected to the outer surface of the fixed tube 2 near the bottom end, and the drill pipe body 1 is penetrated inside the fixed tube 2. Before drilling, the fixed tube 2 is first installed in the area to be drilled by bolts. Buffers 4 are arranged around the inner surface of the fixed tube 2. Cavities 5 are opened at positions corresponding to the four groups of buffers 4 on the inner surface of the fixed tube 2, and a deviation correction component 6 is arranged between the cavity 5 and the buffer 4. The bottom end of the drill pipe body 1 penetrates the fixed tube 2, and the upper end is connected to the external driving device. Then, the external driving device is turned on to drive the drill pipe body 1 to drive the drill bit to drill, so that the drill bit drills into the ground to work. The buffers 4 correspond to the deviation correction components 6 one by one. The buffer 4 includes a limit column 401, a connecting tube 402, a spring 403, a steel ball 404 and a damper 405; one end of the limit column 401 is fixedly connected to the fixed tube 2, and the other end is movably connected to the connecting tube 402, a spring 403 is arranged inside the connecting tube 402, and one end of the spring 403 is fixedly connected to the connecting tube 402, and the other end is fixedly connected to the limit column 401, and the outer surface of the connecting tube 402 is away from the limit column 401. The end of the end is embedded and rollingly connected with the steel ball 404, and the steel ball 404 is closely fitted with the outer surface of the drill pipe body 1 to reduce friction loss, and the outer surface of the connecting tube 402 is close to the limit column 401. A damper 405 is provided at one end of the limit column 401, one end of the damper 405 is fixedly connected to the fixed cylinder 2, and the other end is fixedly connected to the connecting cylinder 402. When the drill pipe body 1 deviates to one side and contacts the steel ball 404 during rotation, the connecting cylinder 402 located in the inclined direction of the drill pipe body 1 is squeezed by it to squeeze the spring 1 403 and the damper 405 along the direction of the limit column 401. Therefore, the spring 1 403 and the damper 405 can be used to apply a driving force to the connecting cylinder 402 to keep moving in the vertical direction, so that the inclination amplitude of the drill pipe body 1 can be buffered and adjusted, and the deviation angle of the drill pipe during the process can be reduced.

[0016] Embodiment 2 like Figure 1-3As shown, the difference between this embodiment and embodiment 1 is that the deviation correction component 6 includes a rack 601, a through hole 602, a rotating shaft 603, a gear 604, a limit bar 605, a connecting shaft 606 and a rectangular ring 607; the outer surface of the connecting cylinder 402 is fixedly connected with a rack 601 at a position below the damper 405, and the rack 601 corresponds to the cavity 5, and a through hole 602 is opened at a position on the inner surface of the cavity 5 corresponding to the rack 601, and the rack 601 passes through the through hole 602 and extends to the inside of the cavity 5, and one side of the inner surface of the cavity 5 is rotatably connected with a rotating shaft 603, and one end of the rotating shaft 603 is rotatably connected to the cavity 5, and the other end A gear 604 is fixedly connected, and the rack 601 is located above the corresponding gear 604 and meshes with it. When the connecting tube 402 is pushed by the drill pipe body 1 to move in the direction of the extrusion spring 403, the rack 601 moves toward the inside of the cavity 5 along the through hole 602, so the gear 604 rotates under the drive of the rack 601. The outer surfaces of both sides of the rack 601 are fixedly connected to the limit bars 605 to limit the rack 601. At the same time, the surface rack 601 is separated from the through hole 602, and a limit groove is provided at the position corresponding to the through hole 602 and the limit bar 605, and the limit bar 605 and the limit groove are mutually matched and movably connected; A connecting shaft 606 is fixedly connected to a position near the edge of the outer surface of the gear 604 away from the rotating shaft 603, and a rectangular ring 607 is movably connected to the outer surface of the connecting shaft 606. The connecting shaft 606 drives the rectangular ring 607 on its surface to move in a direction close to the inner wall of the fixed cylinder 2. One end of the connecting shaft 606 away from the gear 604 passes through the rectangular ring 607 and is fixedly connected to a limiting block to prevent the connecting shaft 606 from being separated from the rectangular ring 607. A connecting column 608 is fixedly connected to the outer surface of one side of the rectangular ring 607. One end of the connecting column 608 is fixedly connected to the rectangular ring 607, and the other end passes through the outside of the cavity 5 and is fixedly connected to the adjustment component 7. The connecting column 608 is movably connected to the cavity 5. The connecting column 608 pushes the adjustment component 7 to move in a direction close to the drill pipe body 1, and the drill pipe body 1 moves in a direction to keep itself vertical.

[0017] Embodiment 3 like Figure 1 , Figure 4 and Figure 5As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that the adjustment assembly 7 includes a movable ring 701, a ball 702, a movable cavity 703, a fixed rod 704, a piston plate 705 and a damping spring shock absorber 706; one end of the connecting column 608 penetrates into the interior of the fixed cylinder 2 and is fixedly connected with the movable ring 701, and the drill pipe body 1 penetrates the movable ring 701, and the inner surface of the movable ring 701 is annular and equidistantly embedded with four groups of balls 702 rollingly connected to reduce the friction loss generated during the drilling process, and the movable ring 701 is provided with an movable cavity 703 at one end away from the connecting column 608, and the movable ring 701 Pushed by the connecting column 608, it moves toward the direction close to the drill rod body 1, and the ball 702 contacts the drill rod body 1 and pushes the drill rod body 1 to move in the direction to keep itself vertical. Therefore, when the drill rod body 1 deviates, it can be straightened in time to keep the drill rod body 1 vertical as a whole during the downward exploration process, avoiding damage to the drill rod body 1 due to uneven force caused by deviation. A fixed rod 704 is fixedly connected to the position of the inner surface of the fixed tube 2 corresponding to the movable cavity 703, and one end of the fixed rod 704 is fixedly connected to the fixed tube 2, and the other end passes through the interior of the movable cavity 703 and is movably connected to it.

[0018] In the process of the drill pipe body 1 moving in the vertical direction, the connecting tube 402 pushes the steel ball 404 to always fit with the drill pipe body 1 under the action of the spring 403, thereby driving the rack 601 to drive the gear 604 to rotate, and the internal movability of the movable cavity 703 is connected with the piston plate 705, and the outer surface of the piston plate 705 is tightly fitted with the inner surface of the movable cavity 703, the piston plate 705 is fixedly connected to the fixed rod 704, and the inner surface of the movable ring 701 corresponding to the movable cavity 703 is provided with an air guide hole 707, the inner surface of the air guide hole 707 penetrates into the interior of the movable cavity 703, and the outer surface of the movable ring 701 is close to the fixed rod 704. A damping spring shock absorber 706 is provided on one side of the fixed rod 704, and the movable ring 701 returns to its original state under the joint action of the damping spring shock absorber 706 and the connecting column 608, and one end of the damping spring shock absorber 706 is fixedly connected to the movable ring 701, and the other end is fixedly connected to the fixed cylinder 2. In the process of the movable ring 701 moving along the fixed rod 704, the piston plate 705 and the movable cavity 703 move relative to each other, and the air around the movable ring 701 enters and is discharged from the movable cavity 703 through the air guide hole 707, which accelerates the rate at which the heat generated during the friction between the ball 702 and the drill pipe body 1 is dissipated outward, thereby reducing the friction loss.

[0019] Embodiment 4 like Figure 1-6 As shown, a method for operating a petroleum drilling device with an anti-drift mechanism comprises the following steps: Step 1: Before drilling, first install the fixed tube 2 in the area to be drilled by bolts, then make the bottom end of the drill pipe body 1 pass through the fixed tube 2 and the movable ring 701, and connect the upper end with the external driving device, then turn on the external driving device to drive the drill pipe body 1 to drive the drill bit to drill, so that the drill bit drills into the ground to work; Step 2: When the drill rod body 1 deviates to one side during rotation and contacts the steel ball 404, the connecting tube 402 located in the tilting direction of the drill rod body 1 is squeezed by the steel ball 404 to squeeze the spring 1 403 and the damper 405 along the direction of the limit column 401. Therefore, the spring 1 403 and the damper 405 can be used to apply a driving force to the connecting tube 402 to keep moving in the vertical direction, so that the tilting amplitude of the drill rod body 1 can be buffered and adjusted. Step 3: When the connecting tube 402 is pushed by the drill pipe body 1 to move in the direction of the extrusion spring 403, the rack 601 moves along the through hole 602 toward the inside of the cavity 5, so the gear 604 rotates under the drive of the rack 601, and the connecting shaft 606 drives the rectangular ring 607 on its surface to move toward the inner wall of the fixed tube 2. The movable ring 701 moves toward the drill pipe body 1 under the push of the connecting column 608, and the ball 702 contacts the drill pipe body 1 and pushes the drill pipe body 1 to move in the direction to keep itself vertical. Therefore, when the drill pipe body 1 deviates, it can be corrected in time, so that the drill pipe body 1 can be kept vertical as a whole during the downward exploration process, avoiding damage to the drill pipe body 1 due to uneven force caused by deviation. Step 4. During the movement of the drill pipe body 1 to maintain the vertical direction, the connecting tube 402 pushes the steel ball 404 under the action of the spring 1 403 to always fit with the drill pipe body 1, thereby driving the rack 601 to drive the gear 604 to rotate, and the movable ring 701 is restored to its original state under the joint action of the damping spring shock absorber 706 and the connecting column 608. During the movement of the movable ring 701 along the fixed rod 704, the piston plate 705 and the movable cavity 703 move relative to each other, and the air around the movable ring 701 enters and is discharged from the movable cavity 703 through the air guide hole 707, which accelerates the rate at which the heat generated during the friction between the ball 702 and the drill pipe body 1 is dissipated outward, thereby reducing the friction loss.

A petroleum drilling equipment with an anti-deviating mechanism according to any one of claims 1 to 5, characterized in that: The operating method of the oil drilling equipment comprises the following steps: Step 1: Before drilling, firstly, the fixing tube (2) is installed in the area to be drilled by means of bolts, and then the bottom end of the drill rod body (1) is passed through the fixing tube (2) and the movable ring (701), and the top end is connected to an external driving device, and then the external driving device is turned on to drive the drill rod body (1) to drive the drill bit to drill, so that the drill bit drills into the ground to work; Step 2: When the drill rod body (1) deviates to one side during rotation and contacts the steel ball (404), the connecting tube (402) located in the tilting direction of the drill rod body (1) is squeezed by the steel ball (404) to squeeze the spring 1 (403) and the damper (405) along the direction of the limit column (401). Therefore, the spring 1 (403) and the damper (405) can be used to apply a driving force to the connecting tube (402) to keep moving in the vertical direction, thereby buffering and adjusting the tilting amplitude of the drill rod body (1); Step 3: When the connecting tube (402) is pushed by the drill rod body (1) to move in the direction of the extrusion spring 1 (403), the rack (601) moves along the through hole (602) toward the inside of the cavity (5), so that the gear (604) rotates under the drive of the rack (601), and the connecting shaft (606) drives the rectangular ring (607) on its surface to move in the direction close to the inner wall of the fixed tube (2). The movable ring (701) moves in the direction close to the drill rod body (1) under the push of the connecting column (608), and the ball (702) contacts the drill rod body (1) and pushes the drill rod body (1) to move in the direction to keep itself vertical. Therefore, when the drill rod body (1) deviates, it can be corrected in time, so that the drill rod body (1) can be kept vertical as a whole during the exploration process, and the drill rod body (1) can be prevented from being damaged due to uneven force caused by deviation. Step 4: During the movement of the drill rod body (1) in the vertical direction, the connecting tube (402) pushes the steel ball (404) under the action of the spring 1 (403) to always fit the drill rod body (1), thereby driving the rack (601) to drive the gear (604) to rotate, and the movable ring (701) is restored to its original state under the joint action of the damping spring shock absorber (706) and the connecting column (608). During the movement of the movable ring (701) along the fixed rod (704), the piston plate (705) and the movable chamber (703) move relative to each other, and the air around the movable ring (701) enters and is discharged from the movable chamber (703) through the air guide hole (707), thereby accelerating the rate at which the heat generated during the friction between the ball (702) and the drill rod body (1) is dissipated outwards, thereby reducing the friction loss.
