Description

Technical Field

[0001] The invention belongs to the technical field of underground coal mine measurement while drilling instruments, and relates to a near-drill-bit measurement while drilling short section structure for coal mines and an assembly method thereof. Background Art

[0002] The measurement while drilling technology in underground coal mines is a key component of coal mine directional drilling equipment. It is mainly used to monitor the drilling trajectory, geological parameters and drilling engineering parameters in real time. With these data, operators can adjust the drilling trajectory of the drill rig in time according to the changes in the drilling process, so as to ensure that the borehole reaches the specified position accurately. This is particularly important in coal mining, especially when it is necessary to cross complex geological layers. Accurately controlling the drilling path helps improve mining efficiency and safety. However, the existing measurement while drilling technology has some obvious limitations.

[0003] Traditional underground coal mine measurement while drilling systems are mostly installed in non-magnetic drill rods behind the screw motor, usually 5 to 8 meters away from the drill bit. A major problem with this design is measurement lag, that is, while the drill is drilling at the front end, there is a large distance between the measurement point and the actual position of the drill bit, resulting in the collected trajectory data being unable to reflect the actual working conditions of the drill bit in real time. This lag will cause untimely trajectory adjustments, which may cause the borehole to deviate from the designed route, increase operational risks and engineering complexity, especially in areas where coal and rock formations change frequently, where existing systems are difficult to provide accurate real-time data.

[0004] At present, the surface oil field has developed near-drill bit measurement while drilling devices, but they are mostly used for large-diameter drilling in oil drilling. These devices have the characteristics of large diameter and long length, and cannot be directly applied to small-diameter directional drilling in coal mines. The main reasons are: first, the near-drill bit measurement while drilling devices developed in the oil field do not meet the special explosion-proof requirements of coal mines; second, they are generally large in diameter and too long in length, which does not meet the requirements of small-diameter directional drilling in coal mines, and seriously affects the slope rate of the screw motor. Summary of the invention

[0005] In view of this, the purpose of the present invention is to solve the problem that the existing downhole measurement system of coal mines has delayed measurement points and cannot measure the drilling trajectory and geological parameters in time, and to provide a downhole measurement short section structure near the drill bit for coal mines and its assembly method.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] Furthermore, a fixing ring is provided at one end of the protective cover away from the outer tube. The fixing ring is composed of two halves. The fixing ring is clamped on the wireless transmitting connector. The protective cover is sleeved on the fixing ring and supported by the fixing ring.

[0012] Furthermore, the communication hole includes a transverse hole arranged along the axial direction and an inclined hole arranged obliquely, and an aviation plug assembly is provided in the inclined hole, and the aviation plug assembly is used for electrical connection and sealing the inclined hole.

[0013] Furthermore, a gap is provided between the transmitting antenna assembly and the protective cover, and the gap is filled with sealing material.

[0014] Furthermore, the battery assembly, gamma measurement module, inclination measurement module, and measurement circuit board are provided with vibration-damping sealing pads in the radial direction and at both ends to prevent the vibration of the hole bottom from damaging the electronic components.

[0015] Preferably, the structural parts of the outer tube, wireless transmitting short section, battery assembly, gamma measurement module, inclination measurement module and measurement circuit board are all made of non-magnetic steel materials to reduce magnetic interference and ensure the accuracy of measurement data.

[0016] An assembly method of the above-mentioned coal mine near-drill bit measurement while drilling short section structure comprises the following steps:

[0017] Step 1, Preparation before assembly: Check the integrity of components: Make sure all components, including the outer tube, wireless transmitter short section, battery assembly, gamma measurement module, inclination measurement module, measurement circuit board, electronic compartment frame, transmitting antenna assembly, protective cover, fixing ring and vibration damping seal are complete and intact; prepare the necessary tools, torque wrench, thread sealant, insulating tape, and sealing materials;

[0018] Step 2: Install the electronic components: insert the electronic bin frame into the outer tube, so that one end of the frame fits with the connecting thread end face of the outer tube and the other end is connected to the wireless transmitting short section;

[0019] Installation of battery assembly: embed the waist-shaped battery assembly into the waist-shaped groove on the electronic warehouse frame, install the gamma measurement module, inclination measurement module and measurement circuit board into the three evenly distributed arc grooves on the electronic warehouse frame, and arrange them in a ring; use wires to connect the battery assembly, gamma measurement module, inclination measurement module and measurement circuit board in sequence; install vibration-damping sealing pads in the radial direction and at both ends of the battery assembly, gamma measurement module, inclination measurement module and measurement circuit board to ensure that they are firmly fixed;

[0020] Step 3, installation of the wireless transmitter short section: connect the wireless transmitter short section to one end of the outer tube through a straight thread, and tighten it to the specified torque with a torque wrench; pass the communication wire through the communication hole in the wireless transmitter short section and connect it to the aviation plug assembly; insert the aviation plug assembly into the oblique hole of the wireless transmitter short section, and tighten it to seal the oblique hole to ensure the protection performance;

[0023] The beneficial effects of the present invention are:

[0024] 1. The present invention sets the measuring sub at a position less than 0.5 meters away from the end of the drill bit, which greatly shortens the distance between the measurement point while drilling and the drill bit. Compared with the traditional measurement while drilling system that needs to be installed in a non-magnetic drill rod 5 to 8 meters away from the drill bit, the present invention can monitor the trajectory and geological parameters during the drilling process in real time, significantly reducing the problem of measurement data lag. This can help the operator adjust the drilling trajectory more accurately, improve the automation and intelligent control accuracy of directional drilling, and thus improve the safety and efficiency of underground drilling operations in coal mines.

[0025] 2. The present invention significantly reduces the diameter and length of the MWD short section by optimizing the structure of the outer tube and the electronic chamber frame, so that it can adapt to the narrow drilling space in the coal mine. At the same time, the small diameter design of the present invention also reduces the impact on the deflection ability of the screw motor, ensuring that the directional drilling equipment can work smoothly.

[0026] 3. The present invention arranges the gamma measurement module, the inclination measurement module, the measurement circuit board and the battery assembly in a ring shape outside the electronic compartment frame, making full use of the internal space and achieving a compact structure. This design not only effectively reduces the overall size of the device, but also improves the system integration. At the same time, the ring-shaped battery assembly increases the battery capacity, prolongs the battery life of the device, and ensures that the measurement while drilling system can continue to work stably during long-term drilling operations.

[0027] 4. The present invention adopts an intrinsically safe circuit design to ensure the safety of the MWD device in the complex environment of coal mines. The intrinsically safe circuit can effectively prevent electrical equipment from causing sparks or overheating when a fault occurs, thereby avoiding the occurrence of explosion accidents in coal mines and improving the safety of the equipment in explosive environments.

[0028] 5. The present invention adopts a wireless transmitting short section structure, which solves the problem of measuring data transmission across the screw motor, and can transmit the data collected by the gamma measurement module and the inclination measurement module to the receiving short section behind the screw motor in real time through wireless signals. The transmitting antenna assembly is embedded in the annular groove of the short section and protected by a protective cover and sealing materials to ensure the stability and reliability of wireless signal transmission. This optimized design is not only used for waterproofing, but also reduces the risk of damage caused by vibration and friction between coal and rock formations.

[0029] 6. The present invention provides vibration-damping sealing pads at both ends of the battery assembly, gamma measurement module, inclination measurement module and measurement circuit board, which effectively absorbs vibration impact during the drilling process, protects internal precision electronic components, and prolongs the service life of the equipment.
