Description

Technical Field

[0001] The utility model relates to the technical field of drilling, and more particularly to an automatic clip-on rope coring drilling structure and a complex stratum real-time monitoring coring drilling system. Background Art

[0002] my country is gradually increasing its efforts in marine and terrestrial geological surveys and advancing the planning of deep-sea and terrestrial scientific drilling missions. The key to these efforts lies in obtaining physical samples from deep within the Earth through drilling. However, obtaining high-quality physical samples requires monitoring the actual working conditions of the drill tool at the bottom of the well and the drilling trajectory while drilling and coring, allowing for timely adjustment of process parameters. This approach, unlike conventional core claw extraction methods, reduces disturbance and core entry resistance to samples in complex formations, thereby improving sample quality and recovery rates.

[0003] In the prior art, a patent document with application publication number CN118346205A discloses a method for advanced drilling and coring in complex heterogeneous formations: step 1, before drilling, the adjustment mechanism drives the drill cutter to move in a direction away from the center end of the coring port; step 2, the drive device is started to drive the drill rod body to rotate, and the drill cutter is simultaneously driven to rotate to cut the soil; step 3, the adjustment mechanism drives each group of drill cutters to move in a direction close to the center end of the coring port, so that each group of drill cutters seals the coring port and supports the soil located in the drill bit end; step 4, the drill rod body is removed from the soil, and the coring is completed.

[0004] The drill bit is mounted at the bottom end of the drill pipe body, and is provided with a coring port connected to the interior of the drill pipe body. A positioning ring is integrally positioned near the coring port, and the circumferential surface of the positioning ring is provided with a plurality of positioning slots. Each positioning slot is slidably embedded within a drill cutter. Each drill cutter is connected to an adjustment mechanism that drives it along the positioning slot. The adjustment mechanism includes a positioning seat fixedly connected to the drill cutter and a push rod disposed thereon. A turntable is rotatably disposed within the drill bit, and the turntable has a plurality of chute slots disposed thereon in a circular array. The chute slots are arc-shaped and extend from the near-center end of the turntable toward the far-center end. The turntable is connected to the rotation mechanism. A plurality of positioning plates are arranged in a circular array on the drill bit, each with a through slot. A stopper is fixedly disposed on the push rod, and the stopper is fixedly connected to a movable seat slidably disposed within the through slot via a stop rod. The positioning plate also features a support, one side of which is fitted with a sleeve. The other end of the sleeve slidably engages a telescopic rod fixedly connected to the movable seat; a return spring is mounted on the telescopic rod. The rotating mechanism includes a rotating shaft fixedly connected to the turntable, with a first gear mounted on the end of the shaft. The first gear meshes with a rotatable second gear, which is fixedly connected to the drive motor.

[0005] While the above structure can achieve the desired cutting and support effects for the sample, it is complex and requires a power drive. Furthermore, for some complex formations, the bottom of the sample after coring is relatively loose. Based on this characteristic, the above structure can still be simplified.

[0006] Therefore, how to provide a simple and reliable automatic clamping type rope coring drilling structure and coring drilling system that does not require external force is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0007] In view of this, the utility model provides an automatic clamping type rope coring drilling structure and a real-time monitoring coring drilling system, aiming to solve the above technical problems.

[0009] An automatic clamping type wireline coring drilling structure includes a coring device mechanism, wherein the coring device mechanism includes a jet joint, an outer tube, a sealing seat and an inner drill bit that are threadedly connected in sequence; and further includes:

[0010] A liner, the liner being sleeved on the inner sides of the outer tube and the sealing seat and being pressed tightly between the jet joint and the end face of the inner drill bit, wherein a plurality of windows are circumferentially opened on a side wall of the liner close to the inner drill bit;

[0011] An elastic claw, the elastic claw is rotatably connected to the mounting opening opened on the side wall of the sealing seat, the number of the mounting openings is the same as the number of the windows, and corresponds one-to-one to the multiple windows, one end of the elastic claw is connected to the mounting opening through a rotating shaft, and a torsion spring is installed on the rotating shaft, when the elastic claw rotates around the rotating shaft to compress the torsion spring to store force, the elastic claw fits against the inner wall of the sealing seat, and the elastic claw is located in the window, at this time, the hinge point of the elastic claw is located at the lower part of the elastic claw.

[0013] Preferably, in the above-mentioned automatic clamping rope coring drilling structure, the axial height of the window is higher than the axial height of the mounting opening. The opening design of the window and the mounting opening can meet the folding, storage and unfolding of the elastic clamping claws, so that they do not interfere with each other during operation.

[0014] Preferably, in the aforementioned automatic-clamping wireline coring drilling structure, a sealing assembly is sheathed on the outer wall of the bottom end of the sealing seat, the sealing assembly being pressed tightly between the stepped surface of the outer wall of the sealing seat and the end face of the inner drill bit. The sealing assembly is used to achieve a seal with the outer tube assembly.

[0017] Preferably, in the above-mentioned automatic clamping type rope coring drilling structure, when the elastic clamping claw overcomes the torsion spring to rotate, the length of the elastic clamping claw located inside the sealing seat is greater than the length of the elastic clamping claw located outside the sealing seat.

[0018] The utility model also provides a real-time monitoring coring drilling system, comprising a coring outer tube assembly and a coring inner tube assembly which is placed in or out of the coring outer tube assembly via a rope salvage device with a steel wire rope;

[0019] The coring inner tube assembly includes a rope salvage mechanism, a suspension mechanism, a monitoring while drilling mechanism, a mud pulse transmission mechanism, and the coring device mechanism, which are sequentially connected from top to bottom.
