Description

Technical Field

[0001] This invention relates to the field of petroleum exploration technology, specifically to a convenient mobile and positioning coiled tubing drilling downhole system. Background Technology

[0002] The characteristics of coiled tubing drilling include no joints or diameter changes, small size, large curvature, continuous tripping capability, high strength, strong pressure resistance, and the ability to achieve dynamic sealing. It provides a scientific, advanced, and safe technology for drilling and is widely used in oilfield drilling. In the redevelopment and utilization of oil wells, it increases the production of oil and gas and improves the economic benefits of oilfield enterprises, thus having high economic value.

[0003] Referring to a Chinese patent, a coiled tubing electric drilling device (Publication No.: CN111441720A, Publication Date: 2020-07-24), this patent solves the problem that while existing coiled tubing drilling technology with a positive displacement screw motor can precisely access reservoirs, it is easily limited by the displacement of the positive displacement screw motor. Furthermore, the positive displacement screw motor experiences pressure drop, resulting in excessive circulating pressure and preventing large-volume circulation of drilling fluid. This leads to problems such as low annular return velocity of the drilling fluid when operating in large wellbores, hindering the carrying of drill cuttings and significantly limiting the application range of coiled tubing. However, existing coiled tubing drilling systems still have the following shortcomings:

[0004] (1) There are two types of existing coiled tubing drilling systems: cable and wireless. Cable systems are expensive, difficult to maintain, and have high requirements for the operating environment. Wireless systems cannot currently meet the increasingly demanding operational requirements, such as high build-up rate, high operational efficiency, and long lifespan of downhole equipment.

[0005] (2) After drilling, the soil and gravel drilled out by the drilling equipment will accumulate around the well. These soil and gravel are relatively loose. If they are not treated, they will accumulate higher and higher and eventually flow into the well, burying the well and affecting drilling efficiency. There is a lack of automated soil treatment equipment to efficiently treat the soil and gravel.

[0006] (3) Existing drilling equipment is inconvenient to position and stabilize during drilling. The equipment shakes greatly and is not stable during drilling, which can easily lead to deviations in the drilling position.

[0007] To address these issues, we propose a convenient and mobile coiled tubing drilling downhole system. Summary of the Invention

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides two technical solutions, specifically including the following embodiments:

[0036] Example 1

[0037] Please see Figure 1-4A convenient mobile and positioning coiled tubing drilling downhole system includes a base plate 1. Four through slots 2 are formed in the bottom of the base plate 1. Four casters 3 are mounted on the bottom of the base plate 1. A handle 4 is fixed to one side of the top of the base plate 1. A support frame 5 is mounted above the base plate 1. Four square tubes 6 are fixed to the support frame 5. Positioning and stabilizing components 7 are installed inside each of the four square tubes 6. A traction roller 8 is rotatably connected inside the support frame 5. A first motor 9, a three-phase asynchronous motor, is fixed to one side of the support frame 5. The first motor 9 is capable of forward and reverse rotation, controlled by an external switch, and electrically connected to an external power source. The output end of the first motor 9 is fixed to one side of the traction roller 8. Two [unclear text - possibly related to the base plate 1] are fixed to one side of the top of the base plate 1. A vertical rod 10 is slidably connected to a movable frame 11 between the opposite sides of the two vertical rods 10. A rotating roller 12 is rotatably connected between the top ends of the two vertical rods 10. The traction roller 8 and the rotating roller 12 are connected by a traction rope 13. A pull ring 14 is fixed to the top of the movable frame 11. One end of the traction rope 13 is bound to the pull ring 14. When the first motor 9 rotates forward, it can drive the traction roller 8 to retract the rope, and the traction rope 13 drives the movable frame 11 to move upward. When it rotates in reverse, it drives the movable frame 11 to move downward. After moving downward, it is convenient for the drill bit 25 to drill. From top to bottom, the bottom of the movable frame 11 is installed with a connector 17, a motor head assembly 18, a weight rod 19, a three-dimensional stabilizer 20, a coiled tubing directional indexing tool 21, and a titanium alloy drill pipe. 22. Directional joint; 23. Downhole power drilling tools; 24. Drill bit; 25. The drill bit is a tool used to break rocks and form a wellbore during drilling. Driven by a downhole power motor, the drill bit rotates, causing the entire bit to move in a centripetal motion, cutting and grinding the rock to create cracks and break it, thus driving the drilling downwards. A drilling mud lifting system is installed on the surface to lift soil and drill cuttings from the bottom of the well to the surface. Rock cuttings in the well are circulated to the surface via mud. The drilling depth is 3000 meters, and can reach more than 5000 meters. This system typically includes a mud lifting pump and a mud-gas separator. The mud lifting pump uses pressure to pump soil and drill cuttings to the surface, while the mud-gas separator... The device is used to separate gas and solid particles to ensure safe handling. Currently, there are many types of drill bits used in the oil industry, which can be divided into PDC drill bits, roller cone drill bits, and scraper drill bits. Downhole power drill tools 24 are directional drilling tools used for drilling, which are divided into three categories: motor / screw, turbine, and electric drill tools. Motor / screw drill tools are more commonly used, especially for short-radius and ultra-short-radius drilling, and high-bend or double-bend motor / screw drill tools are recommended according to the curvature radius requirements. The directional joint 23 can be connected to flexible MWD tools, US friction reduction and drag reduction tools, and drilling shock devices at both the upper and lower ends. Direction is achieved by rotating the tool face through the indexing tool, and then adjusting to the required tool face orientation with the help of drilling pressure.Flexible MWD tools are logging-while-drilling (MWD) tools, available in wired or wireless configurations. Wired MWD requires cables, which are costly, difficult to maintain, and have stringent environmental requirements. Wireless MWD demands higher instrument performance due to the long coiled tubing, typically exceeding 5000 meters, requiring strong and stable signals. For short-radius and ultra-short-radius drilling, the MWD and external non-magnetic drill string must possess a certain degree of flexibility to smoothly navigate high-build-up sections. High build-up rates are achieved using dual-bend motors or flexible motors. US friction-reducing tools are used in wells with high friction, such as short-radius or ultra-short-radius wells, and to increase the drilling extension length of horizontal wells. The MWD shock absorber is used to dislodge stuck parts downhole. Titanium alloy drill pipe 22 is a lightweight drill pipe that effectively reduces friction and torque in horizontal wells, significantly extending the horizontal offset and horizontal section length. Its stress corrosion fatigue strength is 10 times higher than that of currently used carbon steel. The titanium alloy drill pipe 22 can significantly increase the drill string's damage tolerance and service life. Due to its high mechanical strength, good flexibility, excellent corrosion resistance, and low specific gravity, it can be used not only in conventional wells but also in ultra-short radius wells, ultra-large reach wells, and other challenging drilling conditions. Furthermore, using a lightweight drill string composed of titanium alloy drill pipe can reduce hook load, torque, and friction, further improving the mechanical drilling rate. Titanium alloy also has non-magnetic properties. The coiled tubing indexing tool 21, because the coiled tubing cannot rotate, requires a special tool for adjusting the tool face to orient the tubing according to the designed trajectory. During drilling, the coiled tubing indexing tool 21 rotates its lower end via the displacement and pressure control of a surface pump, driving the MWD and motor below the tool to rotate a certain angle. This rotation angle can be infinitely adjusted via pressure. The coiled tubing indexing tool 21 is powered by the pressure generated by the fluid. Once the pressure inside the tool reaches its threshold pressure, it rotates by a corresponding angle. Each rotation can be a maximum of a clockwise angle. When the pressure drops below the threshold pressure, the tool resets. Reaching the threshold pressure again allows for continued clockwise rotation. This directional indexing tool requires high torque to overcome [various challenges / challenges]. The torque generated by the downhole power drill string used in conjunction with BHA is controlled by rotating the tool face via an indexing tool. Each pump switch rotates the tool face by a certain angle (e.g., 35°), and the drill pressure is then finely adjusted to the required tool face. The three-dimensional stabilizer 20 maintains stable drill pressure and torque through the interaction of internal springs and helices, extending drill bit life, protecting surface equipment, improving drilling efficiency, and eliminating the effects of stick-slip on drilling. Constant torque and drill pressure allow for the use of more aggressive drill bits, increasing drilling speed; it also reduces the impact of downhole vibration on expensive tools, instruments, and drill bits in the drill string assembly; ultimately improving drilling efficiency and profitability.To reduce operational risks, the motor head assembly 18 consists of a double-disc flow valve, a hydraulic release tool, and a circulation valve. As an emergency handling tool, it can establish circulation through the rupture disc's through-hole or drop a ball to shear the release pin, disconnect the tool string, and retrieve the coiled tubing for subsequent retrieval. If the drill bit is buried and a flow path cannot be established, the operating steps are as follows: Both the circulation bypass and emergency release functions of the motor head assembly require dropping a steel ball. The circulation bypass valve is located at the bottom of the tool. A suitable rupture disc is installed, which has two uses when the drill bit is stuck: if the drill bit is buried and circulation is impossible, pressure is applied through the coiled tubing, opening the rupture disc to connect the inside and outside of the coiled tubing. The system establishes a circulation channel and unblocks the blockage. When an emergency release is required, the circulation channel is tested for patency using a blasting disc. Then, the corresponding steel balls are inserted, and pressure is applied to the set pressure value (the pressure can be adjusted according to site requirements by installing the appropriate number of shear pins). After release, the GS-type retrieval tool motor head assembly can be lowered to retrieve the tool. Due to the high flexibility of the coiled tubing, a weight rod is added to the assembly to increase the rigidity of the drill string assembly and to apply drilling pressure. Two automatic soil compaction mechanisms 15 are installed on one side of the top of the base plate 1, and automatic soil separating components 16 are installed on the two automatic soil compaction mechanisms 15.

[0038] Example 2

[0039] Based on Example 1, see Figure 5-7 As shown

[0040] The automatic soil compaction mechanism 15 includes a vertical plate 151 fixed to the top of the base plate. An L-shaped groove 152 is provided through one side of the vertical plate 151. Trapezoidal strips 153 are fixed above and below one side of the vertical plate 151. A movable plate 154 is slidably connected to one side of the vertical plate 151. The top and bottom of the movable plate 154 are provided with inclined surfaces. The top and bottom of the movable plate 154 are slidably connected to the inclined surfaces of the two trapezoidal strips 153. A sloping groove 155 is provided through one side of the movable plate 154.

[0041] A movable rod 156 is slidably connected to one side of the movable plate 154. A movable column 157 is fixed to one end of the movable rod 156. One end of the movable column 157 passes through the inclined groove 155 and the L-shaped groove 152 and extends to the outside of the L-shaped groove 152. The outer surface of the movable column 157 is slidably connected to the inner surface of the inclined groove 155 and the L-shaped groove 152. A fixed rod 158 is fixed to the bottom of the movable rod 156.

[0042] The top end of the fixed rod 158 passes through the movable rod 156 and extends to the top of the movable rod 156. The bottom end of the fixed rod 158 is fixed with a tamping plate 159. The top of the base plate 1 is fixed with a motor base 1510. A second motor 1511 is fixed to one side of the motor base 1510. The second motor 1511 is controlled by the same external switch and is electrically connected to an external power source. The output end of the second motor 1511 passes through the motor base 1510 and extends to the other side of the motor base 1510. A first rotating rod 1512 is fixed to the output end of the second motor 1511. One end of the first rotating rod 1512 is rotatably connected to a second rotating rod 1513 via a rotating shaft. One end of the second rotating rod 1513 is rotatably connected to one side of the movable plate 154 via a rotating shaft.

[0043] The automatic soil separating component 16 includes an L-shaped plate 161 slidably connected to the other side of the vertical plate. An electric telescopic rod 162 is fixed to the bottom of the L-shaped plate 161. The electric telescopic rod 162 is existing technology. Both electric telescopic rods 162 are controlled and activated by the same external microcontroller. The microcontroller can control the time interval between the opening and closing of the electric telescopic rods 162 (when the moving plate 154 is reset, it controls the two electric telescopic rods 162 to close; when the two moving plates 154 move in opposite directions, it controls the two electric telescopic rods 162 to start). It is electrically connected to an external power source. The connection is as follows: a soil dividing plate 163 is fixed to one side of the movable plate 154, and an installation plate 164 is fixed to one side of the soil dividing plate 163. The output end of the electric telescopic rod 162 is fixed to the top of the installation plate 164. The compaction plate 159 is slidably connected to one side of the soil dividing plate 163. Through the setting of the automatic soil compaction mechanism 15, the soil and gravel divided to both sides of the wellhead are automatically compacted. It works in conjunction with the automatic soil dividing component 16 to prevent loose soil and gravel around the wellhead from sliding into the well, thereby improving the drilling efficiency.

[0044] The positioning and stabilizing component 7 includes a fixing block 71 fixed inside the square tube 6. The inner surface of the fixing block 71 is threaded with a threaded rod 72, the top end of which passes through the fixing block 71 and extends to the top of the square tube 6.

[0045] The top end of the threaded rod 72 is fixed with a rotating handle 73, and the bottom end of the threaded rod 72 passes through the fixing block 71 and extends to the outside of the fixing block 71.

[0046] The bottom end of the threaded rod 72 is fixed with a soil drill rod 74. The bottom end of the threaded rod 72 is fixed with the top end of the soil drill rod 74. The bottom end of the soil drill rod 74 passes through the square tube 6 and the through groove 2 and extends to the bottom of the base plate 1. The positioning and stabilizing component 7 enables rapid positioning and stabilization of the drilling equipment, making the equipment work more stably during drilling. The four casters 3 enable rapid transportation and movement of the drilling equipment, which is highly flexible and improves transportation efficiency. The positioning and stabilizing component 7 can adjust the depth of the soil drill rod 74 into the soil according to the drilling depth. The deeper the soil drill rod 74 drills, the more stable the entire system becomes.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0048] During operation, rotating the four handles 73 causes the threaded rod 72 to rotate, simultaneously moving it downwards along the inner surface of the fixed block 71. This also causes the drill rod 74 to rotate downwards, eventually drilling into the soil and securing it. Drilling begins by starting the drill bit 25, and simultaneously activating two electric telescopic rods 162, which in turn move the two soil-separating plates 163 downwards. Further activation of the two second motors 1511 causes the two first rotating rods 1512 to rotate, which in turn rotate the two second rotating rods 1513. These second rotating rods 1513 then move the two moving plates 154 back and forth. As the two moving plates 154 move in opposite directions, they simultaneously move the two moving columns 157 along the inner surface of the L-shaped groove 152. Laterally sliding, when the two moving columns 157 move to the corner of the L-shaped groove 152, the moving columns 157 slide downward along the inner surface of the inclined groove 155. At the same time, the moving columns 157 slide downward along the inner surface of the L-shaped groove 152. Simultaneously, the moving columns 157 drive the moving rod 156, the fixed rod 158, and the compaction plate 159 to move downward. Finally, the compaction plate 159 compacts the soil and gravel on one side of the soil separating plate 163. When the moving plate 154 returns to its original position, the electric telescopic rod 162 is closed, causing the electric telescopic rod 162 to drive the soil separating plate 163 to move upward and return to its original position. The above process is repeated to compact the soil and gravel accumulated around the well. Through the setting of the automatic soil separating component 16, the soil and gravel drilled out during the drilling process are moved to both sides of the wellhead, making the land around the wellhead flat and facilitating workers to operate equipment around the wellhead.

All equivalent changes and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
