Therefore, it is particularly important to develop detection and optimization systems that can monitor and optimize drilling parameters in real time. These systems can help operators adjust the direction and speed of the drill bit in time to prevent the drill bit from deviating from the predetermined trajectory, reduce drilling risks, and improve resource recovery.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0040] The drill bit slope monitoring system includes a gravity sensor and a protection system. The gravity sensor is installed at the rear of the drill bit and is used to monitor and measure the drill bit slope and well inclination in real time. The protection system protects and optimizes the normal operation of the gravity sensor and provides accurate data by reducing vibration and impact.

[0041] The data acquisition and transmission system includes a data acquisition unit and a wireless transmission system. The data acquisition unit integrates sensors to collect data on drill bit position, vibration, and torque. The wireless transmission system transmits the data to the ground control center through electromagnetic waves, sound waves, or mud pulses.

[0042] The ground monitoring and analysis system includes a data receiver and decoder and a real-time monitoring platform. The data receiver and decoder receive and decode sensor data from the drilling site. The real-time monitoring platform displays the drill bit position, drilling parameters and wellbore status, providing an intuitive operation interface for operators.

[0043] The data analysis and decision support system includes data analysis software and optimization algorithm modules. The data analysis software performs real-time analysis on the collected data, identifies abnormal situations, and predicts future drilling status. The optimization algorithm module uses optimization algorithms to adjust drilling parameters based on data analysis results to improve drilling efficiency.

[0044] The drilling parameter adjustment system includes an automatic adjustment module that receives instructions from the decision support system and automatically adjusts parameters such as drilling pressure and rotation speed. The human-computer interaction interface allows the operator to manually adjust the drilling parameters or interact with the automatic adjustment system;

[0045] The drilling optimization strategy system includes an intelligent optimization engine, which generates optimization strategies based on current drilling conditions and goals, such as selecting the optimal drill bit and drilling path.

[0046] The entire system forms a closed-loop control by real-time monitoring of drill bit slope, drilling parameters and wellbore status, combined with data transmission and analysis, to improve drilling efficiency and accuracy. The gravity sensor is a key component, and its data is the basis for realizing real-time detection of drill bit slope, which is crucial to the entire detection and optimization system.

[0047] The protection system of the drill bit slope monitoring system specifically includes a drill body 1, and also includes:

[0048] The shock-absorbing box 2 is fixedly installed on the inner wall of the drill body 1, and a slide plate 3 is slidably installed in the shock-absorbing box 2. A buffer spring 4 is arranged between the slide plate 3 and the inner wall of the shock-absorbing box 2, and the buffer spring 4 can play a good buffering role during the sliding process of the slide plate 3. A rubber rod 5 is fixedly installed on the slide plate 3. A through hole with a diameter larger than that of the rubber rod 5 is provided at the bottom of the shock-absorbing box 2 to facilitate the movement of the rubber rod 5. The bottom of the rubber rod 5 is fixedly installed on the outside of the protection frame 6. A damping hole 7 is provided on the slide plate 3 to facilitate the flow of air inside the shock-absorbing box 2 to produce a damping effect. A connecting cable 8 is fixedly installed at the output end of the protection frame 6. The protection frame 6 is composed of three protective shells at the front, middle and rear and a plurality of connecting rods 9. The plurality of connecting rods 9 fix the three protective shells at the front, middle and rear together to form an integral type. There are four groups of shock-absorbing boxes 2, slide plates 3, buffer springs 4 and rubber rods 5. The four groups of shock-absorbing boxes 2, slide plates 3, buffer springs 4 and rubber rods 5 are evenly distributed at ninety degrees between the two groups.

[0049] A groove 16 is provided at the entrance of the protective frame 6, and a right-angled trapezoidal block 17 is slidably installed on the groove 16. An elastic element is provided between the bottom of the right-angled trapezoidal block 17 and the inside of the groove 16. The elastic element here uses a metal spring, so that the sliding of the right-angled trapezoidal block 17 has an elastic restoring force. In the absence of external force, it can be restored to the initial position due to the elastic force. The inclined surface of the right-angled trapezoidal block 17 faces the outside of the protective frame 6, and the right-angled surface faces the inside of the protective frame 6.

[0050] In the above technical solution, the gravity sensor is inserted into the protective frame 6. The gravity sensor will first squeeze the inclined surface of the right-angled trapezoidal block 17 to squeeze the right-angled trapezoidal block 17 into the groove 16. Then the gravity sensor continues to be inserted. The gravity sensor is inserted into the front end of the protective frame 6 and is in contact with the connecting cable 8. At this time, the gravity sensor leaves the right-angled trapezoidal block 17, and the right-angled trapezoidal block 17 will return to the initial position due to the elastic force of the elastic element. The gravity sensor will be stuck by the right-angled surface of the right-angled trapezoidal block 17, and the installation is completed. During use, when the drill body 1 vibrates due to work or changes in slope, multi-directional vibrations will be generated, so that the protective frame 6 will generate multiple displacement vibrations in different directions due to the multi-directional vibrations. When the protective frame 6 vibrates and displaces in the direction of the connecting cable 8 (that is, it moves forward), the protective frame 6 will pull the rubber The rod 5 follows the movement, and the rubber rod 5 will bend at the outlet of the shock absorbing box 2 at the same time. The rubber rod 5 pulls the slide plate 3 to slide downward, and the slide plate 3 will pull the buffer spring 4 to stretch, so that the buffer spring 4 will have a buffering effect to achieve the shock absorbing effect. At the same time, during the sliding of the slide plate 3, the air will produce a certain damping effect through the damping hole 7, thereby achieving the effect of auxiliary buffering and shock absorption. By designing four groups of shock absorbing boxes 2, slide plates 3, buffer springs 4 and rubber rods 5, each of which is evenly distributed at 90 degrees, whenever the vibration direction changes, there will always be a shock absorbing box 2 to provide a buffering and shock absorption effect for that direction, achieving multi-directional buffering and shock absorption, thereby effectively protecting the safety and stability of the gravity sensor during the working process of the drill body, thereby effectively increasing the accuracy of the gravity sensor in monitoring the slope of the drill bit, and improving the overall work efficiency.

[0051] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, in the present invention, an auxiliary mechanism is also provided on the protection frame 6, and the auxiliary mechanism includes a slip ring 10, which is slidably installed on the connecting rod 9. There are two slip rings 10, and the two slip rings 10 are symmetrically distributed about the center of the protection frame 6. A soft brush 11 is fixedly installed on the inner wall of the slip ring 10, and a conjoined rod 12 is fixedly installed on the outside of the slip ring 10. The conjoined rod 12 connects the two slip rings 10 into one body. A pull rod 13 is rotatably installed on the outside of the slip ring 10, and the top of the pull rod 13 is rotatably installed on the outside of the rubber rod 5. There are two pull rods 13, and the two pull rods 13 are symmetrically distributed about the center of the rubber rod 5. An auxiliary cylinder 15 is slidably installed at the outlet of the shock absorber box 2, and an elastic element is provided between the outside of the auxiliary cylinder 15 and the inner wall of the shock absorber box 2. Here The elastic element uses a metal spring, which makes the sliding of the auxiliary tube 15 have elastic restoring force. The auxiliary tube 15 can return to its initial position without the action of external force. One end of the auxiliary tube 15 is provided with an outward edge to prevent it from detaching from the shock absorber box 2, and the top of the other end is set as an annular arc end to reduce the friction damage between the rubber rod 5 and the auxiliary tube 15. The annular arc end of the auxiliary tube 15 is arranged on the outside of the shock absorber box 2 and the edge is arranged inside the shock absorber box 2. A pressure rod 14 is rotatably installed on the annular arc end at the bottom of the auxiliary tube 15, and the bottom of the pressure rod 14 is rotatably installed on the outside of the connected rod 12. The outer diameter of the auxiliary tube 15 is the same as the diameter of the outlet of the shock absorber box 2, and the inner diameter of the auxiliary tube 15 is the same as the diameter of the rubber rod 5, so that the auxiliary tube 15 can slide against the outer wall of the rubber rod 5.

[0052] In the above technical solution, when the protection frame 6 vibrates and displaces in the direction of the connecting cable 8 (i.e., it moves forward), the protection frame 6 will pull the rubber rod 5 to bend, causing the rubber rod 5 to tilt, and the rubber rod 5 will push the slip ring 10 on the same side through the pull rod 13 on one side, and the pull rod 13 on the other side pulls the slip ring 10 on the same side, so that the slip ring 10 slides forward under the cooperation of the rubber rod 5 and the pull rod 13, and the slip ring 10 will drive the soft brush 11 to clean dust and other impurities on the outside of the gravity sensor, thereby improving the service life of the gravity sensor and preventing dust aroused by the vibration generated by the work from adhering to the gravity sensor and affecting normal use. At the same time, due to the movement of the slip ring 10, the slip ring 10 will drive the connected rod 12 to move forward, and the connected rod 12 will move forward and pull the bottom of the pressure rod 14 to move, and the top of the pressure rod 14 will pull the auxiliary tube 15 to slide downward. In the process of the auxiliary tube 15 sliding downward, the rubber rod 5 and the bending point at the annular arc end of the auxiliary tube 15 will also move forward. The auxiliary tube 15 will move synchronously with the displacement of the protective frame 6 according to the amplitude of the vibration, and the rubber rod 5 will be pulled out at different distances, and the auxiliary tube 15 will be extended synchronously with the displacement of the protective frame 6, which can effectively ensure the stability of the bending point angle between the rubber rod 5 and the annular arc end of the auxiliary tube 15. By providing an auxiliary tube 15 that can be extended outward, it can automatically adjust according to the amplitude change of the vibrating object, thereby ensuring the stability of the bending point angle, avoiding uneven stress of the rubber rod 5 caused by the change of the bending point angle, optimizing the mechanical properties of the rubber rod 5 under dynamic conditions, reducing stress concentration, and extending the life of the rubber rod 5. The sliding of the auxiliary tube 15 is used instead of complex mechanical or electronic control, which has a simple design, low cost and easy maintenance.

[0057] S4, stable. Due to the movement of the slip ring 10, the slip ring 10 will drive the connected rod 12 to move forward. The connected rod 12 will pull the bottom of the pressure rod 14 to move forward. The top of the pressure rod 14 will pull the auxiliary tube 15 to slide downward. In the process of the auxiliary tube 15 sliding downward, the bending point of the rubber rod 5 and the annular arc end of the auxiliary tube 15 will also move. When the rubber rod 5 is pulled outward, the auxiliary tube 15 will also move outward. This will ensure that the angle of the bending point of the rubber rod 5 and the annular arc end of the auxiliary tube 15 is stable.

A detection optimization method based on a rotary steerable drilling process, characterized in that: The detection optimization system based on the rotary steerable drilling process described in claim 4 comprises the following steps: S1, Installation, the gravity sensor is installed at the rear of the drill bit to monitor and measure the slope and well inclination of the drill bit in real time. The protection system protects and optimizes the normal operation of the gravity sensor and the provision of accurate data by reducing vibration and impact; S2, use, insert the gravity sensor into the protection frame (6), insert the gravity sensor into the front end of the protection frame (6) and contact and connect with the connecting cable (8), the gravity sensor transmits data to the data acquisition and transmission system through the connecting cable (8), when the drill body (1) vibrates due to work or slope changes, multi-directional vibrations are generated, by designing four groups of shock absorbing boxes (2), slide plates (3), buffer springs (4) and rubber rods (5) with two groups evenly distributed at 90 degrees, whenever the vibration direction changes, there will always be a shock absorbing box (2) to provide a buffering and shock absorbing effect for that direction, thereby achieving multi-directional buffering and shock absorbing, protecting the safety and stability of the gravity sensor, and increasing accuracy; S3, auxiliary, when the protection frame (6) vibrates and displaces, the protection frame (6) pulls the rubber rod (5) to bend, and the rubber rod (5) tilts, and the rubber rod (5) pushes the slip ring (10) on the same side through the pull rod (13) on one side, and the pull rod (13) on the other side pulls the slip ring (10) on the same side, and the slip ring (10) slides forward under the cooperation of the rubber rod (5) and the pull rod (13), and the slip ring (10) drives the soft brush (11) to clean the dust on the outside of the gravity sensor; S4, stable. Due to the movement of the slip ring (10), the slip ring (10) will drive the connected rod (12) to move forward. The connected rod (12) will pull the bottom of the pressure rod (14) to move forward. The top of the pressure rod (14) will pull the auxiliary tube (15) to slide downward. In the process of the auxiliary tube (15) sliding downward, the bending point at the annular arc end of the rubber rod (5) and the auxiliary tube (15) will also move. When the rubber rod (5) is pulled outward, the auxiliary tube (15) will also move outward. This will ensure that the angle of the bending point at the annular arc end of the rubber rod (5) and the auxiliary tube (15) is stable. S5, data is transmitted through the data acquisition and transmission system, and then enters the ground monitoring and analysis system, data analysis and decision support system, drilling parameter adjustment system and drilling optimization strategy system in sequence.
