Description

Technical Field

[0001] The present invention relates to the technical field of drilling machinery, and specifically to an energy-saving anti-deviation drilling device. Background Art

[0002] In geological exploration, deviation during drilling can cause the obtained geological samples to lose representativeness and affect the accuracy of reserve assessment. Current engineering specifications generally require the control of borehole verticality at the handover level, and for some ultra-deep holes or boreholes under special geological conditions, the verticality standard is even more stringent. However, deviation problems frequently occur during the drilling process, and their roots are intertwined with multiple factors such as geology, technology, and equipment. Geologically, the anisotropic properties of rocks cause uneven forces on the drill bit. For example, in strata with alternating hard and soft layers, the drill bit is prone to deviation due to the differential drilling pressure; when encountering karst caves and fracture zones, the drill string is extremely likely to lose its guidance and deviate from the designed trajectory. In terms of drilling technology, improper setting of parameters such as drilling pressure and rotational speed, imbalance in the control of the flow rate of the flushing fluid, and the lack of effective guiding devices in the drill string connection and reaming processes will all exacerbate the risk of deviation. In terms of equipment, problems such as unstable installation of the drilling rig and severe wear of the spindle will damage the initial accuracy of the borehole from the source.

A moving seat 23 is installed at the telescopic end of the hydraulic rod 22. A first deviation-correction component 3 is installed above the inner side of the moving seat 23. A second deviation-correction component is installed below the inner side of the moving seat 23. A deviation pressure conversion component 5 is installed at one end inside the moving seat 23. One end of the deviation pressure conversion component 5 is connected to the first deviation-correction component 3, and the other end of the deviation pressure conversion component 5 is connected to the second deviation-correction component in a contact connection manner; The first deviation-correction component 3 includes a second fixed seat 31 installed at the bottom end inside the moving seat 23. A deviation pressure transmission rod 32 is installed horizontally and slidably inside the second fixed seat 31. One end of the deviation pressure transmission rod 32 is installed with a first fitting plate 34; The second deviation-correction component includes a sliding seat 4 slidably installed at the bottom end of the moving seat 23. A second fitting plate 41 is installed at one end inside the sliding seat 4. A connecting plate 42 is installed at the other end inside the sliding seat 4; A first fixed seat 12 is installed at the lifting end of the lifting frame 11. A drilling rig 13 is installed on one side of the first fixed seat 12. The output end of the drilling rig 13 is connected to a drill pipe and a drill bit.

[0017] Example 2. A drilling docking port 21 is opened at the front end of the drilling stabilizing seat 2. The position of the drilling docking port 21 corresponds to the positions of the drill pipe and the drill bit. The sliding seat 4 is U-shaped, and the size of the sliding seat 4 is adapted to the size of the moving seat 23. The sliding seat 4 can slide smoothly inside the moving seat 23. The position of the second fitting plate 41 is designed to be adjustable. By adjusting the gap between the second fitting plate 41 and the first fitting plate 34, the usage requirements of drill pipes and drill bits of different sizes can be met. A spherical surface 33 is opened at one end of the deviation pressure transmission rod 32. The first fitting plate 34 is arc-shaped. Both the second fitting plate 41 and the first fitting plate 34 are made of wear-resistant materials.

[0018] Embodiment 3. The offset drilling pressure conversion component 5 includes a mounting seat 51 installed at one end inside the moving seat 23. A first rotating arm 52 is rotatably installed inside the mounting seat 51. The first rotating arm 52 is connected to the mounting seat 51 through a first rotating rod 53. Second rotating arms 54 are symmetrically and rotatably installed at the lower end of the first rotating arm 52. The second rotating arms 54 are connected to the first rotating arm 52 through second rotating rods 55. A traction sliding rod 56 is fixed above one side of the second rotating arm 54. A third rotating rod 57 is horizontally fixed inside the moving seat 23 at positions corresponding to the two second rotating arms 54. The height of the third rotating rod 57 is below the connecting plate 42 and will not block the movement of the second offset drilling correction component. A force arm conversion sliding groove 571 is provided at the position of the second rotating arm 54 corresponding to the third rotating rod 57. Both the third rotating rod 57 and the force arm conversion sliding groove 571 are located in the upper half of the second rotating arm 54. The first rotating rod 53 is located at the lower part of the first rotating arm 52. A traction sliding groove 561 is provided at the position of the connecting plate 42 corresponding to the traction sliding rod 56. The traction sliding rod 56 is slidably connected to the connecting plate 42. The third rotating rod 57 is slidably connected to the second rotating arm 54. By means of the force arm conversion of the offset drilling pressure conversion component 5, when the drill pipe and the drill bit are in different inclined states, the conversion of the magnitude of the inclined pressure can be realized, the utilization of the pressure during self-offset drilling can be realized, and it can be converted into an offset drilling correction force to complete the self-correction of offset drilling. Moreover, when the inclination directions of the drill pipe and the drill bit are different, the converted offset drilling correction pressure will also be different, so as to meet the offset drilling correction in different inclined states; An inner groove 6 is provided above one end inside the moving seat 23. A spring 61 is installed inside the inner groove 6. One end of the spring 61 is fixedly connected to the upper end of the first rotating arm 52 for resetting the first rotating arm 52. When the first rotating arm 52 is in a vertical state, the spring 61 is in an initial state.

[0019] During specific use, as an energy-saving anti-offset drilling device, when this design needs to perform drilling, first, move this design to the location where drilling is required, and connect the drill pipe and drill bit of the corresponding model to the output end of the drilling rig 13. At the same time, adjust the gap between the first fitting plate 34 and the second fitting plate 41 to be adapted to the drill pipe and the drill bit; Start the drill rig 13 to drive the drill pipe and the drill bit to drill downward. During the drilling process, there are differences in physical properties such as the hardness and density of different strata. For example, during the drilling process, when entering from a softer soil layer into a harder rock layer, the drill bit will be subjected to uneven resistance at the soft-hard junction, resulting in the drill bit deflecting towards the soft soil layer side. At this time, it will cause the deviation of the overall drilling state, resulting in the inclination and deviation of the drill pipe. When the drill pipe inclines towards the first fitting plate 34, at this time, the inclined pressure acts on a position far from the drill bit and generates a thrust on the first fitting plate 34, pushing the deviation drilling pressure transmission rod 32 to displace horizontally along the second fixing seat 31, and pushing the upper end of the first rotating arm 52 to rotate inwards around the first rotating rod 53. Since the force arm above the first rotating arm 52 is longer, the amplification of the inclined pressure is achieved, and the second rotating rod 55 and the second rotating arm 54 are pulled to rotate around the third rotating rod 57. Since the force arm below the second rotating arm 54 is longer, the secondary amplification of the deviation drilling pressure is thus achieved. At this time, the traction slide rod 56 will pull the connecting plate 42, the sliding seat 4 and the second fitting plate 41 to generate a deviation drilling reset pulling force downward. Due to the action of the secondary force arm, the amplification of the deviation drilling pressure can be realized, the deviation drilling reset efficiency can be improved, and the self-correction of the deviation drilling can be completed. And due to the amplification effect of the secondary force arm, the second fitting plate 41 can obtain a larger displacement space than the first fitting plate 34. Therefore, a set can be arranged in each of the upper and lower layers, so as to realize the self-correction of multi-directional deviation drilling.

Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
