The present application can also be combined with directional screw drilling tools to realize the geological guidance drilling function of deep and long holes and directional holes.

[0044] Figure 2 The following is a flow chart of the rock formation identification method provided in the embodiment of the present application. Figure 2 As shown, the rock formation identification method is applicable to the rock formation identification system in the above embodiment, and the rock formation identification method includes the following steps:

[0045] S201, control the drilling rig to drill at the hole opening position, and collect detection values ​​of at least two types of sensing components in the drilling rig.

[0046] In some embodiments, a drilling area can be determined according to drilling requirements, and a drilling position can be determined within the drilling area. After the drilling position is determined, the drilling machine can be controlled to drill at the drilling position. Optionally, before starting drilling, the working parameters of the drilling machine can be configured, such as the maximum depth of drilling, the maximum duration of drilling, the working power of drilling, the drill bit diameter, the hole opening elevation angle, etc.

[0047] Furthermore, during the drilling process of the drilling rig, detection values ​​of at least two types of sensing components in the drilling rig can be collected according to a set sampling frequency.

[0048] In some embodiments, the sampling frequency can be determined according to the operation requirements. For example, the sampling frequency can be 0.5s. This is only a quantity and cannot be used as a condition to limit this application.

[0049] In some embodiments, at least two types of sensing components in the drilling rig may include but are not limited to: a vibration acceleration sensing component and an azimuth gamma sensing component.

[0050] In some embodiments, the vibration acceleration sensing component is installed in a geological drill bit of a drilling rig to monitor the vibration acceleration value of the drill bit during the drilling process.

[0051] In some embodiments, the azimuthal gamma sensing component is installed in the geological drill pipe of the drilling rig to monitor the azimuthal acceleration value of the drill bit during the drilling process.

[0052] S202: Determine whether the current drilling position of the drilling rig reaches the rock formation interface based on the collected detection values ​​of at least two types of sensing components.

[0053] In some embodiments, after multiple calibration tests, the set critical values ​​for different rock formations can be predetermined, and the set critical values ​​for different rock formations can be stored in the memory of the electronic device in the above embodiments.

[0054] In some embodiments, from the start of drilling, the collected detection values ​​of at least two types of sensing components are compared layer by layer with set critical values ​​of different rock layers to determine whether the current drilling position has reached a certain rock layer interface. In response to the detection values ​​of at least two types of sensing components reaching the set critical values ​​of the i-th rock layer, it can be determined that the current arrival position is the i-th rock layer interface.

[0055] As an example, from the start of drilling, the detection values ​​of at least two types of sensing components are compared with the set critical values ​​corresponding to the first rock layer. In response to the detection values ​​of at least two types of sensing components reaching the set critical values ​​of the first rock layer, it can be determined that the current drilling position has reached the interface of the first rock layer. The drill continues to rotate the hole inward, continues to collect detection values ​​of at least two types of sensing components, and compares them with the set critical values ​​corresponding to the second rock layer. In response to the detection values ​​of at least two types of sensing components reaching the set critical values ​​of the second rock layer, it can be determined that the current drilling position has reached the interface of the second rock layer, and so on, until the drilling end condition is met and the drilling can be ended.

[0056] In some embodiments, the drilling end condition may include that the cumulative drilling depth of the current drilling reaches a preset drilling depth, and / or the cumulative drilling time of the current drilling reaches a preset drilling time.

[0057] In some embodiments, a curve drawing cycle can be set, and each time a curve drawing cycle is reached, the curve graph drawn in the previous drawing cycle can be updated based on the detection value of the sensing component collected within the drawing cycle. In the embodiment of the present application, by drawing the curve corresponding to the sensing component, the changing trend of the detection value can be intuitively reflected, so as to monitor the safety of the detection process or adjust the detection parameters.

[0058] In some embodiments, during the drilling operation of the drilling rig, the detection value and drilling data of each type of sensing component are transmitted to the electronic device in the above embodiments by wireless electromagnetic waves.

[0059] S203, in response to the current drilling position reaching the rock layer interface position, determine the thickness of the rock layer according to the drilling data of the drilling rig.

[0060] In some embodiments, the drilling data between two adjacent rock layer interface positions may be marked to determine the drilling data of each rock layer. That is, starting from the moment when the drilling rig reaches the i-th rock layer interface, the drilling data between the i-th rock layer interface position and the i+1-th rock layer interface position may be extracted as the drilling data corresponding to the i+1-th rock layer.

[0061] In some embodiments, the drilling data corresponding to the rock formation may include but are not limited to: the number of drill rods drilled, the drilling time of the rock formation, the starting position of the drilling corresponding to the rock formation, the inclination of the drilling, etc. Further, the thickness of the rock formation is obtained by back-calculating according to the drilling data corresponding to each rock formation. Optionally, the length of a single drill rod can be predetermined, and further, based on the number of drill rods in the drilling data, the drilling process from the i-th layer to the i+1-th layer is determined, that is, the number of drill rods and the length of a single drill rod are multiplied to obtain the drilling process from the i-th layer to the i+1-th layer. Further, the drilling process is corrected in combination with the detection value of the sensing component to obtain the actual drilling process. After obtaining the actual drilling process, the thickness corresponding to the rock formation is obtained in combination with the starting position of the drilling corresponding to the rock formation. Further, the thickness corresponding to the rock formation can be corrected in combination with the inclination of the drilling to obtain the vertical thickness corresponding to the rock formation.

[0062] In some embodiments, the drilling data from the i-th layer to the i+1-th layer generate drilling description information for each rock layer, so that the drilling description data of different rock layers can be obtained under certain query conditions in the future. Furthermore, statistical analysis can be performed on multiple drilling description data of the same rock layer to determine the drilling characteristic information of the same rock layer, so as to guide the subsequent regional action.

[0063] The rock formation identification method provided in the embodiment of the present application can determine whether the drilling rig has reached the rock formation interface through the detection value sensed by the sensing component, and then determine the thickness of the rock formation based on the operation data between the two adjacent interfaces and the data of the sensing component. Compared with the traditional rock formation coring and slag drilling records and geophysical prospecting technical methods, the present application uses a single borehole azimuth gamma and hole bottom vibration acceleration digital acquisition method to record and analyze the rock formations and interfaces encountered in real time, thereby improving the efficiency and accuracy of rock formation interface detection and reducing technical costs. The present application can also be combined with directional screw drilling tools to realize the geological guidance drilling function of deep and long holes and directional holes.

[0064] Figure 3 The following is a flow chart of the rock formation identification method provided in the embodiment of the present application. Figure 3 As shown, the rock formation identification method is applicable to the rock formation identification system in the above embodiment, and the rock formation identification method includes the following steps:

[0065] S301, determining the drilling position of the tunnel according to the rock formation detection requirements.

[0066] S302, adjusting the drilling rig's position and determining the drilling position according to the ground information of the drilling position.

[0067] In some embodiments, images of the ground at the drilling location are captured, and ground information of the drilling location is identified based on the captured images. Optionally, the ground information includes surface types, flatness, hardness information, etc. of different candidate drilling areas.

[0068] Furthermore, based on the ground information, the best drilling area is determined from multiple candidate drilling areas, and based on the ground flatness of the best drilling area, the drill rod angle and drill bit offset of the drilling rig are determined, and based on the drill rod angle and drill bit offset, the hole opening position of the best drilling area is determined.

[0069] For example, the drill bit diameter is 120mm, the designed depth of the test borehole is 500m, the opening elevation angle is 15°, the vibration acceleration probe range is 0-40g, the natural gamma probe range is 0-200API, the length of a single drill pipe is 3m, the single drilling time is 3-10min, the wireless transmission acquisition frequency is 0.5s, and during the drilling process, the vibration acceleration and azimuthal natural gamma curves are drawn every one minute using an explosion-proof computer outside the hole; when the relative change of the drill bit vibration acceleration and natural gamma pulse data reaches more than 20% of the set critical value, the position of the rock interface encountered is determined, and the vertical thickness of each rock layer drilled through is calculated.

[0070] The rock formation identification method provided in the embodiment of the present application can determine whether the drilling rig has reached the rock formation interface through the detection value sensed by the sensing component, and then determine the thickness of the rock formation based on the operation data between the two adjacent interfaces and the data of the sensing component. Compared with the traditional rock formation coring and slag drilling records and geophysical prospecting technical methods, the present application uses a single borehole azimuth gamma and hole bottom vibration acceleration digital acquisition method to record and analyze the rock formations and interfaces encountered in real time, thereby improving the efficiency and accuracy of rock formation interface detection and reducing technical costs.
