Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
[0020] Embodiment 1 Please refer to Figure 1 , the present invention provides a technical solution: a high-speed transmission wireless while-drilling inclinometer, including a drilling-in monitoring module, a drilling monitoring module, an inclination warning module and a server. The drilling-in monitoring module, the drilling monitoring module and the inclination warning module are respectively connected to the server, and the server controls the drilling-in monitoring module, the drilling monitoring module and the inclination warning module respectively; The drilling-in monitoring module obtains the initial time period when the drill bit enters the ground, analyzes the inclination angle of the drill bit of the earth drill in the initial time period when the drill bit enters the ground, and obtains the inclination deviation degree of the drilling-in angle corresponding to the initial time period when the drill bit enters the ground according to the analysis result; Specifically as follows: During the process of monitoring the inclination of the earth drill, the time point when the drill bit of the earth drill contacts the ground is marked as the start time point of the cycle, the time point when the drill bit of the earth drill completely penetrates into the ground is marked as the end time point of the cycle, and the time period between the start time point of the cycle and the end time point of the cycle is marked as the initial drill-into-the-ground time cycle of the drill bit; It should be noted here that: In this application, the earth drill involved here is specifically a geological drill; In this application, the working condition of the earth drill involved here is specifically the drilling of the earth drill in the vertical direction to the ground, and does not involve the drilling in the horizontal direction.
[0021] Analyze the inclination angle of the earth drill in the initial drill-into-the-ground time cycle of the drill bit, and obtain the inclination deviation degree of the drill-in angle according to the analysis result; Specifically as follows: During the initial drill-into-the-ground time cycle of the drill bit, select several drill-in monitoring time points, and name the selected several drill-in monitoring time points in sequence according to the time sequence as the R1 drill-in monitoring time point to the Ra drill-in monitoring time point; It should be noted here that: In this application, R involved here is the symbol corresponding to the drill-in monitoring time point, and a involved here is the numerical value corresponding to the drill-in monitoring time point, and a is an integer greater than 0.
[0022] Monitor the inclination angle of the geological drill at the R1 drill-in monitoring time point, and obtain the earth drill inclination angle value corresponding to the R1 drill-in monitoring time point; Specifically as follows: When monitoring the inclination angle of the geological drill at the R1 drill-in monitoring time point, mark the ground as the first reference position plane; Select a ground reference point at any position on the ground, and draw a perpendicular line to the first reference position plane through the ground reference point to obtain the inclination angle reference line; Obtain the non-contact area of the drill bit in the non-contact area corresponding to the geological drill bit, mark several regional feature points in the non-contact area of the drill bit, and arbitrarily select a sample regional feature point from the obtained multiple regional feature points; It should be noted here that: In this application, the non-contact area of the drill bit involved here is specifically the surface area where the drill bit does not have direct contact or effective cutting action with the formation during the drilling process, but this area and the contact area of the drill bit are in a physical structure, and the connection method does not have physical buffering; Obtain the central axis of the geological drill bit to get the first drill bit feature line, obtain the tip point of the geological drill bit to get the first drill bit feature point, and draw a plane perpendicular to the first drill bit feature line through the first drill bit feature point to get the monitoring point position projection plane; Obtain the projection points of the feature points in the sample area on the projection plane at the monitoring point positions to obtain the sample area projection points. Connect the sample area projection points with the sample area feature points to obtain the inclination angle lines corresponding to the sample area feature points; Draw a line parallel to the inclination angle reference line through the sample area feature points to obtain the inclination angle reference line corresponding to the sample area feature points. Obtain the included angle value formed by the inclination angle reference line and the inclination angle line at the sample area feature points to obtain the inclination angle value corresponding to the sample area feature points; Repeat the process of obtaining the inclination angle values corresponding to the sample area feature points, respectively obtain the inclination angle values corresponding to each area feature point, and calculate the average of the obtained multiple inclination angle values to obtain the ground drill inclination angle value corresponding to the R1 drilling-in monitoring time point; Repeat the process of obtaining the ground drill inclination angle value corresponding to the R1 drilling-in monitoring time point, respectively obtain the ground drill inclination angle values corresponding to the R2 drilling-in monitoring time point to the Ra drilling-in monitoring time point, to obtain the R1 drilling-in inclination angle value to the Ra drilling-in inclination angle value; Respectively obtain the drilling-in inclination angle reference values corresponding to the R1 drilling-in monitoring time point to the Ra drilling-in monitoring time point, to obtain the R1 inclination angle reference value to the Ra inclination angle reference value; It should be noted here that: In this application, the R1 inclination angle reference value to the Ra inclination angle reference value involved here are respectively the average values of the inclination angle reference intervals corresponding to each R1 drilling-in monitoring time point to the Ra drilling-in monitoring time point; The R1 inclination angle reference interval to the Ra inclination angle reference interval are all provided by the historical working data of the geological drill.
[0023] Calculate the inclination deviation degree of the drilling-in angle corresponding to the initial ground entry time period of the drill bit by using the R1 drilling-in inclination angle value to the Ra drilling-in inclination angle value and the R1 inclination angle reference value to the Ra inclination angle reference value; Calculate the inclination deviation degree of the drilling-in angle corresponding to the initial ground entry time period of the drill bit. The specific formula is as follows: ; Wherein, Rzj is the inclination deviation degree of the drilling-in angle corresponding to the initial ground entry time period of the drill bit, Rjri is the Ri drilling-in inclination angle value, Rjji is the Ri inclination angle reference value, and a is the numerical value corresponding to the drilling-in monitoring time point; It should be noted here that: In this application, the reference value of the inclination angle of Ri involved here can be any reference value of the inclination angle from the reference value of the inclination angle of R1 to the reference value of the inclination angle of Ra, and the numerical value of the inclination angle of Ri during initial drilling involved here can be any numerical value of the inclination angle during initial drilling from the numerical value of the inclination angle of R1 during initial drilling to the numerical value of the inclination angle of Ra during initial drilling; Obtaining the inclination deviation degree of the drilling angle corresponding to the initial ground entry time period of the drill bit has the following advantages: By selecting multiple monitoring time points during the initial ground entry time period of the drill bit, obtaining the corresponding ground drilling inclination angle numerical value and the reference value of the inclination angle during initial drilling for each time point respectively, and calculating the inclination deviation degree of the drilling angle, it is finally possible to achieve an accurate assessment of the inclination state of the drill bit during the initial ground entry stage. This process can clearly present the difference between the actual change of the inclination angle of the drill bit during the initial ground entry process and the expected standard, providing key data support and decision-making basis for subsequent drilling operations; The initial ground entry of the drill bit is a dynamic process, and its inclination angle may change continuously over time. Selecting only one time point for monitoring cannot comprehensively reflect the inclination of the drill bit during the entire initial ground entry stage. By selecting multiple time points, a series of continuous inclination angle data can be obtained, so as to more accurately capture the change trend of the inclination angle of the drill bit; The reference value of the inclination angle during initial drilling involved here is pre-determined according to factors such as drilling design requirements, formation conditions, and rig performance, representing the ideal inclination state that the drill bit should reach during the initial ground entry stage. Comparing the actually monitored inclination angle numerical value with the reference value can intuitively reflect the inclination of the drill bit; The comparison between the simple inclination angle numerical value and the reference value can only give a qualitative judgment. Here, by calculating the inclination deviation degree, this difference can be quantified, more accurately reflecting the deviation degree between the inclination of the drill bit and the expected standard.
