Description

Technical Field

[0001] This utility model relates to the field of geological drilling technology, and in particular to a flexible drilling guidance device adapted to complex geological formations. Background Technology

[0002] Drilling guidance systems are devices used in drilling operations to precisely control the drilling direction of the drill bit. Through sensors, control systems, and mechanical structures, they monitor and adjust the drilling trajectory in real time, ensuring it moves along a preset path and avoiding deviations. Widely used in oil and gas extraction and geological exploration, they improve drilling efficiency, reduce blind drilling, and are key equipment for achieving directional drilling and precise operations in complex formations. Current drilling guidance systems rely on fixed stabilizers or mechanical pushers, which cannot sense changes in the formation in real time and dynamically adjust the direction. Difficulty in controlling the build-up rate leads to low guidance accuracy, thus requiring improvement. Utility Model Content

[0043] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a flexible drilling guidance device adapted to complex strata.

[0044] A flexible drilling guidance device adapted to complex strata includes an installation body 1 and a flexible guidance mechanism disposed on the installation body 1 for guiding operations. The flexible guidance mechanism includes a flexible guide section 2 disposed on the installation body 1 for guiding operations; a flexible hinge 3 disposed on the flexible guide section 2 for flexibly adjusting the direction; a mounting member 4 disposed on the flexible guide section 2 and fixedly connected to the flexible guide section 2; multiple fixing members 5 disposed on the mounting member 4 and fixedly connected to the mounting member 4; and multiple hydraulic cylinders 6 disposed within the fixing members 5 and fixedly connected to the fixing members 5.

[0045] refer to Figure 1 and Figure 2 In a preferred embodiment, the flexible guide mechanism further includes: a protective device disposed on the upper part for component protection; and a detection component disposed within the protective device for detection work.

[0046] refer to Figure 2 and Figure 3 In a preferred embodiment, the protective device includes: a mounting part disposed on the flexible guide joint 2 for component mounting; and a buffer part disposed on the mounting part for buffering operation.

[0047] refer to Figure 4In a preferred embodiment, the mounting part includes: a mounting cylinder 7, which is disposed on the flexible guide joint 2 and fixedly connected to the flexible guide joint 2; and multiple mounting grooves 8, which are disposed on the mounting cylinder 7 for component mounting.

[0048] refer to Figure 4 and Figure 5 In a preferred embodiment, the buffer part includes: a plurality of buffer springs 9, wherein the plurality of buffer springs 9 are disposed in the mounting groove 8 and fixedly connected to the mounting groove 8; and a protective shell 10, disposed on the buffer springs 9 and fixedly connected to the buffer springs 9.

[0049] refer to Figure 5 In a preferred embodiment, the detection component includes: a plurality of pressure sensors 11, which are disposed on the mounting cylinder 7 and fixedly connected to the mounting cylinder 7; and a plurality of tilt sensors 12, which are disposed on the mounting cylinder 7 and fixedly connected to the mounting cylinder 7.

[0050] In this configuration, the flexible hinge 3 is made of carbon fiber reinforced composite material, which has high elasticity and fatigue resistance, allowing the guide joint to bend within a range of ±15°; multiple flexible guide joints 2 and flexible hinges 3 are provided in this device, and adjacent flexible guide joints 2 are connected by flexible hinges 3.

[0051] This device, through the flexible guiding mechanism, can automatically adjust its bending angle according to changes in the geological formation, adapting to complex conditions such as uneven hardness and inclined bedding. The flexible guiding mechanism, combined with carbon fiber composite materials and vibration-damping design, extends the device's lifespan, while its explosion-proof and corrosion-resistant structure ensures stable operation in harsh environments.

[0052] Working Principle: When this device is conducting underground exploration, it can adjust the exploration position according to the complexity of the underground conditions and the softness of the geology. Pressure sensor 11 and tilt sensor 12 monitor each flexible guide section 2. When the flexible guide section 2 deviates from its designated position due to geological reasons, the hydraulic cylinders 6 around the flexible hinge 3 work together to adjust the rotation angle of the flexible hinge 3, thereby adjusting the position of the flexible guide section 2. This flexible adjustment prevents the flexible guide section 2 from shifting during drilling operations, which could lead to drilling errors. During operation, the buffer spring 9 dampens the pressure sensor 11, tilt sensor 12, and flexible guide section 2, ensuring operational stability.

[0053] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
