Description

Technical Field

[0001] This invention belongs to the field of directional drilling technology, and particularly relates to a directional drilling system. Background Technology

[0002] Drilling is a crucial part of mineral exploration engineering. Power drilling tools, as drilling equipment, are widely used in the construction of complex well structures such as directional and horizontal wells. They not only control the wellbore trajectory to achieve drilling objectives but also effectively improve drilling efficiency, which is beneficial for the exploration and development of unconventional oil and gas reservoirs and increases oil and gas production. To more accurately measure the angular difference between instruments and power drilling tools, a mark needs to be made at the bypass valve of the power drilling tool, matching the position of the high side. During drilling, excessive borehole curvature increases the rotational resistance of the drilling tool, making it difficult for the tool to rotate within the hole; this leads to drill bit deviation and further causes excessive borehole curvature. Currently, the most primitive method of marking is still used for positioning. This method requires rotating and fixing the power drilling tool to visually determine the mark position, which introduces significant errors in accurate measurement and cannot ensure the verticality of the borehole.

[0003] Patent CN108952577A discloses a drill bit positioning and orientation device, including a power drill bit, a guide shaft, and a reaming drill bit. The guide shaft has a first threaded connector at its ground end. The power drill bit is externally fitted onto the first threaded connector of the guide shaft, and the reaming drill bit is fitted internally at the end of the guide shaft. A three-way water guide groove is formed on the outer surface of the guide shaft. This drill bit positioning and orientation device has a reasonable structure, is simple to operate, and improves the accuracy of positioning and orientation. Simultaneously, the water guide groove on the guide shaft allows flushing fluid injected from inside the drill pipe during drilling. Under the action of water pressure inside the drill pipe, the water guide groove guides the water in the borehole to flow out of the borehole, acting as a suspension and quickly cleaning away the flushing fluid.

[0004] When adjusting the verticality of drilling, the existing technical solution mentioned above uses threaded transmission for positioning. When the drilling platform surface is not horizontal, the above equipment cannot complete the verticality positioning according to the actual situation. In addition, the fixed end does not form a fixed whole with the ground, which cannot guarantee the positioning deviation caused by mechanical vibration during drilling, resulting in a large error in verticality. Summary of the Invention

[0005] The purpose of this invention is to provide a directional drilling system to solve the problems mentioned in the background section. To achieve the above objective, the following technical solution is provided: a directional drilling system, wherein the equipment includes:

[0006] The support includes legs with bolt holes for fixing; a fixed plate is fixed to the upper end of the legs, and a through hole is fixed to the middle of the fixed plate; a side elevation adjustment mechanism for vertical front-to-back rotation adjustment; a front elevation adjustment mechanism for vertical left-to-right rotation adjustment; a transmission mechanism for driving the front elevation adjustment mechanism to complete the vertical left-to-right rotation adjustment; and a sleeve for placing the drill bit rotating rod in the middle of the front elevation adjustment mechanism.

[0007] In this technical solution, when adjusting the verticality of the drilling orientation, firstly, the bolts are fixed to the drilling position through the bolt holes, and then the position of the through hole is aligned with the top of the drilling. The side elevation adjustment mechanism is manually rotated, and the front elevation adjustment mechanism is driven to swing horizontally through a combination of threaded transmission and lever until the vertical axis of the sleeve is coplanar with the vertical plane. Then, the transmission mechanism is activated, and the lower end face of the front elevation adjustment mechanism is driven to swing horizontally through meshing transmission and worm gear transmission until the sleeve is in a vertical position, thereby correcting the verticality of the drilling. Finally, the rotating rod and the drill bit are fixed through the sleeve to complete the vertical orientation of the drilling.

[0008] In any of the above technical solutions, the further included front facade adjustment mechanism is:

[0009] A large spherical ring block has a spherical groove fixed in its middle. Arc-shaped sliding grooves are fixed at the left and right end walls of the spherical groove, and the upper and lower ends of the spherical groove are open to the outside. Its cross-section is circular. An arc-shaped slider slides in the arc-shaped sliding groove. A connecting plate is fixed in the middle of the arc-shaped slider. A rack is fixed along the extension direction of the arc on the outer arc end face of the connecting plate. A small spherical block is fixed in the middle of the connecting plate. A cylindrical ring hole is opened in the middle of the small spherical block.

[0010] In this technical solution, the small ball block and the ball groove are concentric spheres, and the small ball block, the connecting plate and the arc-shaped slider form a whole. The large ball ring block and the arc-shaped slide groove form a whole. The two wholes can slide relative to each other, thereby realizing the swing of the sleeve in the left and right directions in the vertical plane and realizing the initial adjustment of its verticality.

[0011] In any of the above technical solutions, the front facade adjustment mechanism further includes:

[0012] The second rotating shaft is rotatably connected to the left end of the ball groove. The driven gear is fixedly connected to the middle of the second rotating shaft. The driven gear can mesh with the rack in the connecting plate to drive the small ball block to swing. The center of the small ball block and the arc surface of the ball groove coincide. A turbine is fixedly provided at the rear end of the second rotating shaft. The turbine and the driven gear are two gears fixedly connected to the second rotating shaft. The turbine and the driven gear rotate coaxially. The pitch circle diameter of the turbine is larger than that of the driven gear.

[0013] In this technical solution, the coaxially rotating driven gear and turbine, which are designed to ensure the swing of the front elevation adjustment mechanism angle, drive the turbine with a large pitch circle diameter to rotate, thereby driving the driven gear with a small pitch circle diameter to rotate. This extends the power arm, thereby reducing the power load during the operation of the mechanism and increasing the transmission rigidity and stability of the entire device.

[0014] In any of the above technical solutions, the side facade adjustment mechanism further includes:

[0015] A vertical wall is fixedly mounted on a fixed plate. A rotating groove is fixed in the middle of the vertical wall, and a horizontal rotating shaft is rotatably mounted on it. A swing block is fixed to the right end of the horizontal rotating shaft, and a swing rod is fixed to the upper end of the swing block. A sliding groove is fixed in the middle of the swing rod, and a composite slider slides in the sliding groove. The two ends of the composite slider are cylindrical, and a threaded hole is fixed in the middle. A horizontal lead screw is rotatably mounted in the threaded hole. A support frame is fixed at the upper end of the vertical wall. The two ends of the horizontal lead screw are rotatably connected to the support frame, and the right end of the horizontal lead screw is rotatably embedded in the support frame through a chuck. A handle is fixedly connected to the right end of the horizontal lead screw.

[0016] In this technical solution, the hand rotates the handle, which drives the horizontal lead screw to rotate. The rotation of the horizontal lead screw drives the composite slider to move. During the movement of the composite slider, the two cylindrical ends of the composite slider drive the swing arm to swing. The swing arm and the swing block rotate as a whole around the vertical wall, which drives the entire front facade adjustment mechanism to swing. The adjustment is made until the vertical axis of the sleeve is coplanar with the vertical plane. The self-locking property of the composite slider and the horizontal lead screw when they are engaged is used to fix the adjustment position of the front facade adjustment mechanism.

[0017] In any of the above technical solutions, the transmission mechanism further includes:

[0018] The transmission housing is fixedly mounted on the rear end face of the large ball ring block. A transmission cavity is fixedly provided inside the transmission housing. A stepper motor is fixedly provided on the right end wall of the transmission cavity. The left end of the stepper motor is rotatably connected to the left end wall of the transmission cavity, and a small pulley is fixedly provided in the middle of the stepper motor.

[0019] Advantageously, the transmission mechanism also includes:

[0020] The worm gear is rotatably mounted on the left end wall of the transmission cavity. The left end of the worm gear is rotatably mounted on the large ball ring block, and the worm gear is horizontally positioned with a large pulley fixed on the left end. The large pulley and the small pulley are driven by a belt. Furthermore, the rear end of the second rotating shaft is also rotatably mounted at the rear end of the large ball ring block, and the second rotating shaft is spatially perpendicular to the two rotating shafts of the worm gear. The lower end of the worm gear has a meshing transmission relationship with the worm gear.

[0021] In this technical solution, the stepper motor is started, which drives the small pulley to rotate. When the small pulley rotates, it drives the worm gear to rotate through the large pulley. When the worm gear rotates, the worm gear meshes with the worm wheel, which drives the driven gear connected to the front end of the second rotating shaft to rotate. In this way, the front elevation adjustment mechanism is driven to rotate through the transmission mechanism, thereby realizing the adjustment of its vertical angle.

[0022] In any of the above technical solutions, a sleeve is further provided in the middle of the small ball block, the axis of the sleeve coincides with the axis of the small ball block, and an arc-shaped infeed groove is provided at the upper end of the sleeve for fixing and straightening the drilling shaft.

[0023] In this technical solution, by changing different types of sleeves and altering the orifice diameter, the diameter of the rotating shaft can be adjusted according to different soil types and drilling conditions, thereby increasing the application scenarios of the entire device and improving its usability.

[0024] A method for using a directional drilling system:

[0025] Step 1: Secure the bolts to the drilling position through the bolt holes, and then align the position of the through holes with the top of the drilling well;

[0026] Step 2: Turn the handle by hand to drive the horizontal lead screw to rotate. The rotation of the horizontal lead screw drives the composite slider to move. During the movement of the composite slider, the two cylindrical ends of the composite slider drive the swing arm to swing. The swing arm and the swing block rotate around the vertical wall, causing the entire front elevation adjustment mechanism to swing, adjusting until the vertical axis of the sleeve is coplanar with the vertical plane.

[0027] Step 3: Start the stepper motor. The start of the stepper motor drives the small pulley to rotate. When the small pulley rotates, it drives the worm gear to rotate through the large pulley. When the worm gear rotates, the worm gear meshes with the worm wheel to drive the driven gear connected to the front end of the second rotating shaft to rotate.

[0028] Step 4: After the driven gear rotates, it meshes with the rack on the connecting plate ring surface, driving the lower end face of the front elevation adjustment mechanism to swing horizontally. At this time, the sleeve is in a vertical position, thus ensuring the verticality of the drilling.

[0029] The beneficial effects of this invention are as follows: By setting up a frontal adjustment mechanism, and by setting up a coaxially rotating driven gear and a turbine, the turbine with a large pitch circle diameter and the driven gear with a small pitch circle diameter are driven to rotate, thereby extending the power arm and reducing the power load during the operation of the mechanism, increasing the transmission rigidity and stability of the entire device; by setting up two hemispherical rotating components, the relative sliding between the two components can realize the swing adjustment of the sleeve in the left-right and front-back directions in the vertical plane, thereby realizing the adjustment of the verticality of the directional drill.

Finally, the rotating rod and the drill bit are fixed through the sleeve 50 to complete the vertical orientation of the drilling.

A method of using the directional drilling system of claim 4, characterized in that: Step 1: Fix the bolt to the drilling position through the bolt hole (11), and then keep the position of the through hole (13) aligned with the top of the drilling; Step 2: Turn the handle (29) by hand to drive the horizontal lead screw (27) to rotate. The rotation of the horizontal lead screw (27) drives the composite slider (26) to move. During the movement of the composite slider (26), the cylindrical ends of the composite slider (26) drive the swing rod (24) to swing. The swing rod (24) and the swing block (23) as a whole rotate around the vertical wall (21), driving the entire front elevation adjustment mechanism (30) to swing, adjusting until the vertical axis of the sleeve (50) is coplanar with the vertical plane. Step 3: Start the stepper motor (43). The start of the stepper motor (43) drives the small pulley (44) to rotate. When the small pulley (44) rotates, it drives the worm (48) to rotate through the large pulley (46). When the worm (48) rotates, the worm (48) meshes with the worm gear (39) to drive the driven gear (38) connected to the front end of the second rotating shaft (37) to rotate. Step 4: After the driven gear (38) rotates, it meshes with the rack on the ring surface of the connecting plate (35) to drive the lower end face of the front elevation adjustment mechanism (30) to swing horizontally. At this time, the sleeve (50) is in a vertical position, thus ensuring the verticality of the drilling.
