Description

Technical Field

[0001] This invention relates to the technical field of drilling equipment and its application methods, and is a drilling equipment and its application method based on drilling data and the total well mechanical energy density. Background Technology

[0002] To ensure high profitability and efficiency in oil and gas well development, remote monitoring of the drilling process and optimization of drilling parameters are essential. Mechanical specific energy, calculated using parameters such as drilling pressure, drilling speed, rotational speed, torque, and drill bit diameter, is a comprehensive indicator used to evaluate rock-breaking efficiency. It represents the work (mechanical energy required) the drill bit performs to break a unit volume of rock under drilling pressure and torque, and can serve as a key basis for quantitatively evaluating drilling efficiency.

[0003] In actual drilling operations, the structural features of drill bits can easily cause rock fragments to get stuck. The gaps between the breaking teeth of the drill bit are very easy for rock fragments to get stuck. After large pieces of rock fragments get stuck, the overall outer surface of the drill bit will become smooth, making it difficult for the drill bit to break the rock mass during drilling, thus reducing the breaking efficiency. Summary of the Invention

[0004] This invention provides a full-well mechanical energy specificity drilling device and its usage method based on drilling data, which overcomes the shortcomings of the prior art and can effectively solve the problem that gravel is easily stuck in the gap between the drill bit's breaking teeth, reducing the breaking efficiency.

[0005] One of the technical solutions of this invention is achieved through the following measures: a full-well mechanical energy specificity drilling device based on drilling data, comprising a cylinder, a drill bit, and a fixed seat. A base is provided on the upper part of the drill bit, and the fixed seat is arranged parallel to the outer side of the base. The upper part of the fixed seat is fixedly connected to the cylinder through a connecting rod. An inner seat is provided on the outer side of the base. Multiple push rods are arranged at intervals along the circumference of the fixed seat. Vertical grooves corresponding to the push rods are arranged at intervals along the circumference of the inner seat. The push rods pass through the vertical grooves from top to bottom. The output end of the bottom of each push rod is connected to a top head. A pressure plate is slidably connected to each top head in the direction of movement. A limit seat is provided on the lower outer side of the drill bit. Guide holes that pass through the upper and lower parts are arranged at intervals along the circumference of the limit seat. Each pressure plate is connected to a long rod parallel to the drill bit through a linkage mechanism. The long rod passes through the guide hole. A protrusion is provided on the outer side of each long rod below the limit seat. The protrusion is located between two adjacent breaking teeth of the drill bit.

[0006] The following are further optimizations and / or improvements to one of the above-mentioned inventive technical solutions: The inner ends of the pressure plate opposite to the outer wall of the drill bit can be provided with sliding grooves on the left and right sides respectively. Each sliding groove is fitted with a sliding rod. The inner end of the sliding rod is fixed to the outer wall of the drill bit. A first return spring is fitted on the outer side of the sliding rod. One end of the first return spring is detached and connected to the drill bit, and the other end of the first return spring is detached and connected to the pressure plate. The pressure plate and the two sliding rods are U-shaped as a whole. The corresponding top head can be inserted into the space formed by the pressure plate and the sliding rods.

[0007] The aforementioned top can be a trapezoidal shape that is wider on the inside and narrower on the outside.

[0008] The aforementioned linkage mechanism may include a rocker arm, an extension seat, a bracket, a lower seat, and a bent rod. The lower seat is L-shaped, and a connecting plate is fixedly connected between the top outer end of the lower seat and the pressure plate. An extension seat is fixed to the outside of the drill bit below the pressure plate. The extension seat is U-shaped with its opening facing away from the outer wall of the drill bit. The rocker arm rotates on the extension seat via a pin. The upper end of the rocker arm overlaps the lower seat. The lower end of the rocker arm rotates together with the upper end of the bracket via a pin. The lower end of the bracket rotates together with the upper end of the bent rod via a pin. The lower end of the bent rod is fixedly connected to the upper end of the long rod.

[0009] A second return spring may be provided on the aforementioned bent rod, and the upper end of the second return spring is detachably connected to the drill bit.

[0010] The inner seat side near the vertical slide groove can be provided with a side groove that runs from top to bottom. A rotating wheel is rotatably connected to one side of the push rod corresponding to the side groove, and one end of the rotating wheel is slidably connected to the side groove.

[0011] The second technical solution of the present invention is achieved through the following measures: a method for using a full-well mechanical energy specificity drilling device based on drilling data, comprising: During drilling, the cylinder is activated, which drives the connecting rod to extend and retract vertically. This movement of the connecting rod causes the fixed seat to move up and down as well. When the fixed seat moves downward, it drives the push rod to move down along the vertical groove. As the push rod moves downward, the mandrel moves towards the pressure plate, pushing the pressure plate outward. This outward push of the pressure plate, along with the lower seat, moves the pry bar. The pry bar rotates at the extension seat position, pushing the support. This downward movement causes the support to move downward. As one end of the support moves downward, it pushes down the bent rod, which in turn pushes down the long rod. As the long rod moves downward, it moves along the outer wall of the drill bit, causing the convex head to reach the gap between the breaking teeth. The convex head then pushes out the broken rock, ensuring the drill bit can drill normally.

[0012] This invention, by setting a fixed seat on the drill bit, and designing a push rod, a top head, a linkage mechanism, and a long rod, allows the long rod to be positioned within the gap between the breaking teeth, thereby pushing the stuck gravel away, preventing the gravel from gradually accumulating, ensuring that the drilling efficiency of the drill bit does not decrease, and ensuring that the drill bit can drill normally.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0024] The present invention will be further described below with reference to embodiments: Example 1: As shown in the attached document Figures 1 to 8 As shown, the whole-well mechanical energy specificity drilling device based on drilling data includes a cylinder 1, a drill bit 4, and a fixed seat 7. A base 3 is mounted on the upper part of the drill bit 4, and the fixed seat 7 is parallel to the outer side of the base 3. The upper part of the fixed seat 7 is fixedly connected to the cylinder 1 via a connecting rod 2. An inner seat 9 is mounted on the outer side of the base 3. Multiple push rods 5 are spaced along the circumference of the fixed seat 7. Vertical grooves 12 corresponding to the push rods 5 are spaced along the circumference of the inner seat 9. The push rods 5 pass through the vertical grooves 12 from top to bottom. Each push rod... The output end of the rod 5 is connected to the top head 6. Each top head 6 is slidably connected to the pressure plate 18 in the direction of movement. The lower outer side of the drill bit 4 is provided with a limit seat 8. The limit seat 8 is provided with guide holes 21 that pass through the upper and lower parts along the circumference. Each pressure plate 18 is connected to a long rod 23 parallel to the drill bit 4 through a linkage mechanism. The long rod 23 passes through the guide hole 21. Each long rod 23 below the limit seat 8 is provided with a protrusion 22 on the outer side. The protrusion 22 is located between two adjacent breaking teeth of the drill bit 4.

[0025] The fixed seat 7 can move up and down along the drill bit 4. When the connecting rod 2 moves, it will drive the fixed seat 7 to move, and the fixed seat 7 can drive the push rod 5, which can then slide up and down along the vertical groove 12 of the inner seat 9.

[0026] Optionally, the diameter of the fixed seat 7 is larger than the diameter of the drill bit 4. A corresponding connecting rod 2 is connected to the fixed seat 7. The connecting rod 2 is vertically arranged on the fixed seat 7 and is parallel to the drill bit 4. The connecting rod 2 is located on both sides of the drill bit 4. The diameter of the inner seat 9 is larger than the diameter of the drill bit 4, and the diameter of the inner seat 9 is smaller than the diameter of the fixed seat 7.

[0027] Example 2: Figure 6 , 8 As shown, as an optimization of the above embodiment, the inner end of the pressure plate 18, which is opposite to the outer wall of the drill bit 4, is provided with sliding grooves on the left and right sides respectively. Each sliding groove is fitted with a sliding rod 16. The inner end of the sliding rod 16 is fixed to the outer wall of the drill bit 4, and the outer side of the sliding rod 16 is fitted with a first return spring 17. One end of the first return spring 17 is detached and connected to the drill bit 4, and the other end of the first return spring 17 is detached and connected to the pressure plate 18. The pressure plate 18 and the two sliding rods 16 are U-shaped as a whole, and the corresponding top head 6 can be inserted into the space formed by the pressure plate 18 and the sliding rods 16.

[0028] Example 3: As Figure 6 As shown, as an optimization of the above embodiment 2, the top head 6 is a trapezoidal shape that is wider on the inside and narrower on the outside.

[0029] When the top head 6 moves toward the pressure plate 18, it will push the pressure plate 18 outward. The pressure plate 18 will then drive the first return spring 17 to move outward. When the top head 6 moves away from the pressure plate 18, the first return spring 17 will reset. During the reset process of the first return spring 17, the pressure plate 18 will reset, and the pressure plate 18 will not continue to push the rocker arm 15. The second return spring 24 will reset, and the long rod 23 can then be reset.

[0030] Example 4: Figure 2 , 3 As shown in Figures 6 and 8, as an optimization of the above embodiment, the linkage mechanism includes a rocker arm 15, an extension seat 14, a bracket 20, a lower seat 19, and a bent rod 13. The lower seat 19 is L-shaped, and a connecting plate is fixedly connected between the top outer end of the lower seat 19 and the pressure plate 18. The extension seat 14 is fixedly attached to the outside of the drill bit 4 below the pressure plate 18. The extension seat 14 is U-shaped with its opening facing away from the outer wall of the drill bit 4. The rocker arm 15 rotates on the extension seat 14 via a pin. The upper end of the rocker arm 15 overlaps the lower seat 19. The lower end of the rocker arm 15 rotates together with the upper end of the bracket 20 via a pin. The lower end of the bracket 20 rotates together with the upper end of the bent rod 13 via a pin. The lower end of the bent rod 13 is fixedly connected to the upper end of the long rod 23.

[0031] When the top head 6 moves towards the pressure plate 18, it can push the pressure plate 18, which can be pushed outward. When the pressure plate 18 is pushed outward, it can push the rocker arm 15 through the lower seat 19. When the rocker arm 15 is pushed, it can rotate on the extension seat 14 with a pin. When the rocker arm 15 rotates, the lower end of the rocker arm 15 moves towards the outer wall of the drill bit 4, which can push the support 20. When the support 20 is pushed, it can move downward. When one end of the support 20 moves downward, it can push down the bent rod 13. The bent rod 13 can drive the long rod 23 to push down. When the long rod 23 moves down, it will move along the outer wall of the drill bit 4, so that the long rod 23 can drive the convex head 22 to move down. The convex head 22 is located in the gap between two adjacent breaking teeth of the drill bit 4. The convex head 22 can push the stuck stone outward, thereby pushing the stuck stone away, preventing the stone from gradually accumulating, and ensuring that the drilling efficiency of the drill bit 4 will not decrease.

[0032] The rocker arm 15 can be rotated to drive the bracket 20, and the rocker arm 15 can be restricted by the extension seat 14.

[0033] Example 5: Figure 2 As shown, as an optimization of the above embodiment 4, a second return spring 24 is provided on the bent rod 13, and the upper end of the second return spring 24 is detachably connected to the drill bit 4.

[0034] A second return spring 24 may be provided on the bent rod 13 in the vertical direction.

[0035] Example 6: As Figure 5 ,8 As shown, as an optimization of the above embodiment, a side groove 11 that runs from top to bottom is provided on the side of the inner seat 9 near the vertical slide groove 12. A rotating wheel 10 is rotatably connected to one side of the push rod 5 corresponding to the side groove 11, and one end of the rotating wheel 10 is slidably connected in the side groove 11.

[0036] The rotating wheel 10 is slidably connected in the side groove 11 of the inner seat 9, which can restrict the push rod 5. The push rod 5 will not shift its position when it moves, and will move up and down along the vertical slide groove 12.

[0037] Example 7: The method of using the full-well mechanical energy specificity drilling device based on drilling data described in the above examples includes: During drilling, cylinder 1 is activated, which drives connecting rod 2 to extend and retract vertically. As connecting rod 2 moves up and down, it also moves fixed seat 7 up and down. When fixed seat 7 moves downward, it drives push rod 5 to move downward along vertical slide groove 12. During the downward movement of push rod 5, the top head 6 moves towards pressure plate 18, pushing pressure plate 18 outward. As pressure plate 18 is pushed outward, it pushes rocker arm 15 through lower seat 19. When pushed, the rocker arm 15 rotates at the extension seat 14. When the rocker arm 15 rotates, it pushes the support 20. When the support 20 is pushed, it moves downward. When one end of the support 20 moves downward, it pushes down the bent rod 13. The bent rod 13 drives the long rod 23 to move downward. When the long rod 23 moves downward, it moves along the outer wall of the drill bit 4. The long rod 23 drives the protrusion 22 to the gap between the breaking teeth. The protrusion 22 pushes out the broken stone, ensuring that the drill bit 4 can drill normally.

[0038] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
