Description

Technical Field

[0001] The present invention belongs to the technical field of vertical drilling devices, and in particular relates to a vertical drilling device and method. Background Art

[0002] A vertical drilling rig is a device used for vertical drilling into the ground. It is a critical tool for accessing subsurface resources, particularly in oil and gas exploration and production. The system's operating principle is to measure and process wellbore inclination data using its instruments. When a wellbore inclination trend is detected, hydraulic components are activated, and a telescopic mechanism applies force to the wellbore wall to counteract the inclination. This forces the tool and drill bit toward the bottom of the wellbore, thereby reducing the wellbore's inclination. When the wellbore is completely vertical, the telescopic mechanism fully extends, applying an equal force to the wellbore wall to center the drill bit and maintain vertical drilling. This is a fully automated, repetitive process that requires no human intervention.

[0003] The authorization publication number "CN110965940A" records "an automatic vertical drilling device, which includes a casing mounted on the outside of the drilling drive shaft, and the casing and the drive shaft are connected by a bearing; a pressure conversion cylinder is provided on the outer surface of the casing, and the upper and lower ends of the pressure conversion cylinder are fixedly connected to the casing through the upper sealing end and the deflection correction end respectively, and a pressure chamber is provided between the pressure conversion cylinder and the casing; an annular first piston that moves up and down is provided in the pressure chamber, and a number of push plates are provided around the outer periphery of the deflection correction end, and a drainage hole is provided on the drive shaft, and the drainage hole is connected to the upper end of the pressure chamber through a corresponding drainage channel provided on the casing. While achieving the balanced pressure difference between the inside and outside of the drill tool, the present invention utilizes the pressure of the drilling fluid itself to realize the deflection correction function of the drill bit, does not require the help of other energy, has the advantages of good deflection correction effect and energy saving, and is technically easier to achieve."

[0004] The aforementioned patent is applied to vertical drilling. A drilling deflection correction mechanism is installed near the drill bit end. The mechanism utilizes the pressure of high-pressure water discharged from the borehole during drilling to convert it into hydraulic pressure for correcting the drill bit's deflection. During operation, the device is installed near the drill bit end. A drive shaft drives the drill bit to rotate at high speed. High-pressure drilling fluid discharged from the borehole enters a pressure chamber through a drainage hole provided in the drive shaft. The high-pressure drilling fluid pushes a first piston downward, transmitting pressure to the hydraulic oil below the first piston. The hydraulic oil exerts work on the hydraulic mechanism, pushing a push plate against the wellbore wall. The reaction force from the wellbore wall also pushes the push plate. The simultaneous action of the push plates in all directions prevents drill bit tilt and achieves the purpose of drilling deflection correction. However, the invention overlooks the interference of drill pipes with drill bit tilt during actual vertical drilling operations. Drill pipes are manually docked, which can easily cause the drill bit to deflect during vertical drilling due to manual docking errors. This can lead to real-time correction of the drill bit later, thus reducing the efficiency of vertical drilling operations. Therefore, a vertical drilling device and method are proposed.

[0019] A vertical drilling method comprises the following steps:

[0020] S1. Lift the rod:

[0021] The output ends of the two first electric push rods contract to pull the hollow box down to the bottom of the pipe box. Multiple drill rods are stacked in the pipe box. The two electromagnetic suction cups electromagnetically absorb the single drill rod. The two first electric push rods are powered on and started. The output ends of the two first electric push rods extend to lift the hollow box and the flap, pushing the motor to move upward. The two electromagnetic suction cups lift the single drill rod. The laser locator detects the position of the positioning block in real time by emitting infrared laser. When the single drill rod is lifted to the highest position, the two first electric push rods are powered off and stopped, thereby realizing the lifting of the single drill rod.

[0022] S2, Backswing:

[0023] After the single drill rod is lifted, the pushing motor is powered on and started. The output end of the pushing motor drives the first screw to rotate. The first screw pushes the first slider close to the accommodation box through sliding cooperation with the first slider. The first slider pushes the push-pull rod in one direction, so that the push-pull rod pushes the flip plate in the hollow box to deflect. The flip plate drives the two electromagnetic suction cups to flip. The two electromagnetic suction cups flip and lift the single drill rod, flipping the single drill rod to between the inner walls of the accommodation box, so that the single drill rod is located between the arc guide rod and the two electromagnetic suction cups, thereby realizing the lifting of the single drill rod.

[0024] S3, Docking:

[0025] After a single drill rod is put on, the two electromagnetic suction cups are powered off and demagnetized, and the driving motor is powered on to start the driving motor. The output end of the driving motor drives the second screw to rotate, and the second screw presses the lifting block downward through the sliding cooperation with the lifting block, so that the lifting block drives the rotating motor and the rubber pressing pad to press down, and the rubber pressing pad presses down the upper drill rod, and the bottom of the upper drill rod is inserted into the rotating assembly, and the upper drill rod corresponds to the lower drill rod up and down. At the same time, the rotating assembly clamps the lower drill rod, and the rotating motor is powered on again to start the rotating motor. The output end of the rotating motor drives the rubber pressing pad to rotate, and the rubber pressing pad drives the upper drill rod to rotate, so that the two corresponding drill rods up and down are threadedly connected, thereby realizing the connection of the two drill rods;

[0026] S4, disconnection:

[0027] When it is necessary to cancel the threaded connection between the two drill rods, the rotating assembly pulls up the two connected drill rods, so that the upper drill rod moves into the storage box, and the lower drill rod is clamped between the arc guide rod and the two electromagnetic suction cups. At the same time, the second screw cooperates with the lifting block through sliding, and the rubber pressing pad is squeezed against the upper drill rod. The rotating motor drives the rubber pressing pad to rotate in the opposite direction, so that the upper and lower drill rods are released from the threaded connection, thereby realizing the disconnection between the upper and lower drill rods.

[0028] S5, Downswing:

[0029] After the upper and lower drill rods are disconnected, the two electromagnetic suction cups electromagnetically absorb the single drill rod on the upper side, and the motor is energized to drive the first screw to rotate. The first screw pushes the first slider to reset by sliding with the first slider. The first slider pulls the push-pull rod back to the inner walls of the hollow box. The two electromagnetic suction cups then move the single drill rod to between the inner walls of the pipe box. The two electromagnetic suction cups are powered off and demagnetized, and then the second electric push rod is powered on to start the second electric push rod. The output end of the second electric push rod extends to push the single drill rod on the upper side of the two electromagnetic suction cups into the pipe box, thereby realizing the lowering of the single drill rod.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] In this solution, when a single drill rod is raised or lowered, the first slider pushes and pulls the push-pull rod, which in turn pushes the flap to deflect. The flap drives the single drill rod to move through two electromagnetic suction cups, thereby moving the single drill rod to the accommodating box or taking the single drill rod out of the accommodating box, thereby raising or lowering the single drill rod. By clamping the single drill rod between the arc guide rod and the two electromagnetic suction cups, the upper and lower drill rods in the accommodating box and the rotating assembly are vertically aligned. Mechanical docking of the drill rods is used instead of manual docking to avoid errors caused by drill rod docking, eliminate the deflection of the drill bit during vertical drilling, effectively reduce real-time correction of the drill bit, and improve the efficiency of vertical drilling operations.

[0032] In this solution, when lifting a single drill rod, the output ends of the two first electric push rods contract to pull the hollow box down to the bottom of the pipe box. Multiple drill rods are stacked in the pipe box. The two electromagnetic suction cups electromagnetically absorb the single drill rod, and the two first electric push rods are powered on to start the two first electric push rods. The output ends of the two first electric push rods extend to lift the hollow box and the flap, pushing the motor to move upward. The two electromagnetic suction cups lift the single drill rod, and then the single drill rod is lifted, effectively lifting a single drill rod from multiple drill rods, and realizing the selection of a single drill rod. There is no need for manual selection of a single drill rod, and the vertical drilling device's ability to select drill rods is increased through a mechanical structure, which reduces the workload of the operator of the vertical drilling device and improves the working efficiency of the vertical drilling device.

[0033] In this solution, the two limit rods guide the flipping movement of the flap in an arc by sliding with the two arc grooves, thereby limiting the maximum and minimum deflection angles of the flap, ensuring the stable deflection of the flap, the two electromagnetic suction cups and the single drill rod, avoiding demagnetization and falling off of the single drill rod, and ensuring the stability of the vertical drilling device clamping the single drill rod.

[0034] In this solution, during the lifting and lowering movement of the rubber pressure pad, the output end of the driving motor drives the second screw to rotate, and the second screw lifts the lifting block by sliding with the lifting block, thereby realizing the lifting and lowering of the rotating motor and the rubber pressure pad. When the rubber pressure pad contacts a single drill rod, the rubber pressure pad can drive the single drill rod to rotate, and the rotating assembly clamps or lifts the drill rod, so that the upper and lower drill rods can be threadedly connected or released from the threaded connection, thereby realizing rapid docking or rapid disconnection of the upper and lower drill rods.

[0035] In this solution, the second electric push rod is used to lift the drill rod between the two electromagnetic suction cups, so as to push the drill rod down to the inner wall of the pipe box to achieve rapid rod removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] A vertical drilling method comprises the following steps:

[0072] S1. Lift the rod:

[0073] The output ends of the two first electric push rods 5 contract to pull the hollow box 3 down to the bottom of the pipe box 2. Multiple drill rods are stacked in the pipe box 2. The two electromagnetic suction cups 7 electromagnetically absorb a single drill rod. The two first electric push rods 5 are powered on and started. The output ends of the two first electric push rods 5 extend to lift the hollow box 3 and the flap 6, pushing the motor 16 to move upward. The two electromagnetic suction cups 7 lift the single drill rod. The laser locator 39 detects the position of the positioning block 38 in real time by emitting infrared laser. When the single drill rod is lifted to the highest position, the two first electric push rods 5 are powered off and stopped, thereby realizing the lifting of the single drill rod.

[0074] S2, Backswing:

[0075] After the single drill rod is lifted, the pushing motor 16 is powered on and started. The output end of the pushing motor 16 drives the first screw rod 17 to rotate. The first screw rod 17 pushes the first slider 19 close to the accommodating box 25 through sliding cooperation with the first slider 19. The first slider 19 pushes the push-pull rod 18 in one direction, so that the push-pull rod 18 pushes the flap 6 to deflect in the hollow box 3. The flap 6 drives the two electromagnetic suction cups 7 to flip. The two electromagnetic suction cups 7 flip and lift the single drill rod, flipping the single drill rod to between the inner walls of the accommodating box 25, so that the single drill rod is located between the curved guide rod 29 and the two electromagnetic suction cups 7, thereby achieving the lifting of the single drill rod.

[0076] S3, Docking:

[0077] After a single drill rod is put on, the two electromagnetic suction cups 7 are powered off and demagnetized, and the drive motor 36 is powered on to start the drive motor 36. The output end of the drive motor 36 drives the second screw rod 35 to rotate. The second screw rod 35 presses the lifting block 28 downward by sliding with the lifting block 28, so that the lifting block 28 drives the rotating motor 33 and the rubber pressing pad 34 to press down. The rubber pressing pad 34 presses down the upper drill rod, inserting the bottom of the upper drill rod into the rotating assembly 23, and the upper drill rod corresponds to the lower drill rod up and down. At the same time, the rotating assembly 23 clamps the lower drill rod, and the rotation motor 33 is powered on again to start the rotation motor 33. The output end of the rotating motor 33 drives the rubber pressing pad 34 to rotate, and the rubber pressing pad 34 drives the upper drill rod to rotate, so that the two corresponding drill rods up and down are threadedly connected, thereby realizing the connection of the two drill rods.

[0078] S4, disconnection:

[0079] When the two drill rods need to be unthreaded, the rotating assembly 23 pulls up the two drill rods so that the upper drill rod moves into the accommodating box 25, and the lower drill rod is clamped between the arc guide rod 29 and the two electromagnetic suction cups 7. At the same time, the second screw rod 35 slides with the lifting block 28, and the rubber pressing pad 34 is pressed against the upper drill rod. The rotating motor 33 drives the rubber pressing pad 34 to rotate in the opposite direction, so that the upper and lower drill rods are unthreaded and the upper and lower drill rods are disconnected.

[0080] S5, Downswing:

[0081] After the upper and lower drill rods are disconnected, the two electromagnetic suction cups 7 electromagnetically absorb the single drill rod on the upper side, and the push motor 16 is energized to drive the first screw rod 17 to rotate. The first screw rod 17 pushes the first slider 19 to reset by sliding with the first slider 19. The first slider 19 pulls the push-pull rod 18 back to the inner walls of the hollow box 3. The two electromagnetic suction cups 7 then move the single drill rod to between the inner walls of the pipe box 2. The two electromagnetic suction cups 7 are powered off and demagnetized, and then the second electric push rod 12 is powered on to start the second electric push rod 12. The output end of the second electric push rod 12 extends to push the single drill rod on the upper side of the two electromagnetic suction cups 7 into the pipe box 2, thereby realizing the lowering of the single drill rod.
