[0072] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0073] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0074] See also Figure 1 , which shows a flowchart of the automatic drawing method of the curved trajectory directional drilling profile provided by an embodiment of the present invention, and is described in detail as follows:

[0075] In step S101 , key points are selected on the curve trajectory, wherein the key points include a starting point, an end point, and a plurality of points between the starting point and the end point of the curve trajectory.

[0076] It should be noted that before executing the above steps, it is necessary to copy the plane graphics of the curve trajectory of the drilling profile to be drawn into a new file, enter APPLOAD in the command line of the CAD software to load the above new file, and then enter the D-SECTION command to start the process steps of automatically drawing the curve trajectory directional drilling profile. It can be understood that in order to correctly obtain the information contained in the curve trajectory graphics and to smoothly draw the curve trajectory directional drilling profile, when starting the process steps of automatically drawing the curve trajectory directional drilling profile, the drawing environment can be initialized first, which may include setting the current coordinate system to the world coordinate system, obtaining the object snap mode setting, closing the command line prompt and displaying the program operation precautions, etc. The specific code to implement the above-mentioned initialization function of the drawing environment is:

[0077] (defun init_environment()

[0078] (setvar "cmdecho" 0)

[0079] (if(=(getvar"WORLDUCS")0)(command"ucs"""))

[0080] (setq snap_var(getvar"OSMODE"))

[0081] (prompt"\nGet the length of a point on a curve (spline and polyline) from the starting point of the curve, extract it to the specified CSV file and automatically draw the basic profile graphics. Before use, please copy the curve and related graphics to a dedicated file and then operate. When using, please pay attention to follow the prompts and do not use the Esc key to interrupt the program, otherwise it may cause errors."))

[0082] It should also be noted that in the present invention, the key points, key point location information, point type and attribute value on the curve trajectory can be directly determined from the curve trajectory CAD graphics in the new file opened by CAD, and then the profile parameters can be set to automatically draw the basic profile graphics; the CSV file that stores relevant data saved in advance can also be imported into the CAD software, and the basic profile graphics can be automatically drawn according to the data saved in the CSV file. In the embodiment of the present invention, it can be determined whether to obtain data from the curve trajectory CAD graphics or import data from the CSV file by designing the DCL dialog box. Figure 2 An example diagram of a DCL dialog box for obtaining data from a curve trajectory CAD drawing or importing data from a CSV file provided in an embodiment of the present invention is shown. The DCL dialog box provides two buttons, "OK" and "Cancel". Click OK to directly obtain data from the current curve trajectory CAD drawing, and click Cancel to import data from an existing CSV file with the same format.

[0083] In an embodiment of the present invention, when selecting key points on a curve trajectory, you can check "Intersection" and "Nearest Point" under "Object Snap" in the CAD software, and select points on the curve trajectory through this mode; you can also manually select any point on the curve trajectory, and you can select it in order or not. The specific method of selecting key points on the curve trajectory is not limited here.

[0084] In an embodiment of the present invention, the key points must include the starting point and the end point of the curve trajectory. In order to make the final profile of the curve trajectory directional drilling more vivid, multiple points can be selected between the starting point and the end point of the curve trajectory. The specific number of selected key points is not limited here.

[0085] Optionally, in one embodiment, the above step S101 may include:

[0086] Determine the starting point of the curved trajectory.

[0087] Determines the end point of the curved trajectory.

[0088] Randomly pick multiple points between the start and end points.

[0089] Use the start point, end point, and multiple points as key points to pick on the curve trajectory.

[0090] As mentioned above, the key points include the starting point, the end point, and multiple points between the starting point and the end point of the curve trajectory. When selecting multiple points between the starting point and the end point of the curve trajectory, they can be randomly selected; or the distance range between two adjacent points can be preset, and multiple points can be selected between the starting point and the end point of the curve trajectory according to the preset range. The key points selected in this way are more evenly distributed on the curve trajectory, which can improve the control over the curve trajectory and the effect of the final drawn drilling profile.

[0091] In an embodiment of the present invention, points can also be selected on the curve trajectory according to different geological information. That is to say, according to the geological map of the area where the curve trajectory is located, at least one key point can be included in each geological type when selecting points. The key points selected in this way can make the final borehole profile include all geological types in the geological layer, thereby improving the integrity of the drawing of the borehole profile.

[0092] In a specific embodiment, Figure 3 An example diagram of selecting key points on a curve trajectory provided by an embodiment of the present invention is shown.

[0093] In step S102, the position information of each key point on the curve trajectory is determined.

[0094] In an embodiment of the present invention, the position information of each key point on the curve trajectory can be directly determined from the curve trajectory CAD graphic in the new file opened by CAD, and the position information of each key point on the curve trajectory can be stored in a CSV file; the CSV file saved in advance and storing the position information of each key point on the curve trajectory can also be imported into the CAD software, and the specific method of determining the position information of each key point on the curve is not limited here.

[0095] In an embodiment of the present invention, if the position information of each key point on the curve trajectory is determined directly from the curve trajectory CAD graphic, several key AutoLISP extension functions in the CAD software can be used to determine the position information, and these extension functions include: vlax-ename->vla-object function, which is used to convert the AutoLISP type graphic name into a VLA object, so that other vlax-functions can be used normally; vlax-curve-getStartPoint function, which can return the starting point coordinates of the above-mentioned curve trajectory CAD graphic; vlax-curve-getEndPoint function, which can return the end point coordinates of the above-mentioned curve trajectory CAD graphic; vlax-curve-getDistAtPoint function, which can return the length of the curve segment from the starting point to the specified point of the above-mentioned curve trajectory CAD graphic.

[0096] Optionally, in one embodiment, the position information of each key point on the curve track in the above step S102 includes: the curve length of each key point from the starting point.

[0097] In an embodiment of the present invention, the position information of each key point on the curve trajectory can be the curve length of each key point from the starting point of the curve trajectory, or it can be set as the curve length of each key point from the end point of the curve trajectory according to actual conditions. In an embodiment of the present invention, it is set as the curve length of each key point from the starting point of the curve trajectory. As mentioned above, the vlax-curve-getDistAtPoint function can be used to return the length of the curve segment from the starting point to the specified point of the curve trajectory CAD figure. It can be understood that the vlax-curve-getDistAtPoint function can be used to determine the position information of each key point on the curve trajectory.

[0098] In an embodiment of the present invention, it is necessary to determine the length of the curve from each key point to the starting point of the curve trajectory, and the measurement of a single curve length can be performed through the lengthen and list commands in CAD. The specific measurement method is: interrupt the curve at the position of the key point, and then measure the length of the curve; compared with the method of using the vlax-curve-getDistAtPoint function to determine the position information of each key point on the curve trajectory, the operation is cumbersome and more prone to errors.

[0099] In step S103, the point type of each key point is determined, and the attribute value of each key point is obtained according to the point type.

[0100] As mentioned above, key points are selected on the curve trajectory. The key points include the starting point, the end point and multiple points between the starting point and the end point of the curve trajectory. Since each point on the curve trajectory has specific geological attributes, these geological attributes include but are not limited to contour lines, longitude and latitude grids, faults, tunnels, electrical anomaly areas, collapse columns, geophysical anomaly areas, mining field boundaries, village scopes, protective coal pillars, rivers, etc., and the key point is the intersection of the curve trajectory and these geological attributes. The geological attribute of the intersection is also the point type of each key point.

[0101] In the embodiment of the present invention, each time a key point is selected on the curve trajectory, it is necessary to determine the point type of the key point. The point type of each key point can be determined in the form of a design DCL dialog box.

[0102] Optionally, in one embodiment, the point types in the above step S103 include: curve starting point, curve end point, contour point, longitude and latitude grid point, fault point, tunnel point or electrical abnormal area point.

[0103] In a specific embodiment, Figure 4 An example diagram of the point type selection DCL dialog box provided in an embodiment of the present invention is shown, wherein the point type can be set manually and is not limited here. In this embodiment, it can be set to contour points, longitude and latitude points, fault points, lane points and other points, which are implemented using 5 radio buttons.

[0104] It can be understood that the DCL dialog box can provide a friendly interactive interface, which can visually check the point type of each key point. If there is an error, it can be modified again, which greatly reduces the probability of misoperation.

[0105] In the embodiment of the present invention, the curve starting point and the curve end point in the point type correspond to the starting point and the end point of the curve track in the key point.

[0106] In an embodiment of the present invention, the point type of the key point is the geological information at the intersection, so the point type of the key point includes but is not limited to contour points, longitude and latitude points, fault points, tunnel points, electrical anomaly area points, collapse column points, geophysical anomaly area points, well field boundary points, village range points, protective coal pillar points, river points, etc.

[0107] In the embodiment of the present invention, after the point type of each key point is determined, the point type information of each key point may be stored in a CSV file.

[0108] Optionally, in one embodiment, the above step S103 may include:

[0109] If the point type of a key point is the starting point of a curve, the elevation value of the starting point of the curve is determined as the attribute value of the key point.

[0110] If the point type of a key point is a curve end point, the elevation value of the curve end point is determined as the attribute value of the key point.

[0111] If the point type of a key point is a contour point, the elevation value of the contour point is determined as the attribute value of the key point.

[0112] If the point type of a key point is a longitude and latitude grid point, the horizontal coordinate or vertical coordinate of the longitude and latitude grid point in the geodetic coordinate system is determined as the attribute value of the key point.

[0113] If the point type of a key point is a fault point, the text value corresponding to the fault point is determined to be the attribute value of the key point.

[0114] If the point type of a key point is a lane point, the text value corresponding to the lane point is determined to be the attribute value of the key point.

[0115] If the point type of a key point is an electrical anomaly point, the text value corresponding to the electrical anomaly point is determined to be the attribute value of the key point.

[0116] In an embodiment of the present invention, after the point type of each key point is determined, the attribute value of each key point can be obtained according to the point type, wherein when the point type is a curve starting point, a contour point, a longitude and latitude grid point, or a curve end point, its attribute value must be a numerical value, and the attribute value corresponding to other point types can be a text value or a numerical value corresponding to its name or type.

[0117] In an embodiment of the present invention, if the point type of a key point is a curve starting point, the elevation value of the curve starting point is determined as the attribute value of the key point; if the point type of a key point is a curve end point, the elevation value of the curve end point is determined as the attribute value of the key point; if the point type of a key point is a contour point, the elevation value of the contour point is determined as the attribute value of the key point; if the point type of a key point is a longitude and latitude grid point, the horizontal coordinate or vertical coordinate of the longitude and latitude grid point in the geodetic coordinate system is determined as the attribute value of the key point; if the point type of a key point is a fault point, the text value corresponding to the name of the fault where the fault point is located is determined as the attribute value of the key point; if the point type of a key point is a lane point, the text value corresponding to the name of the lane where the lane point is located is determined as the attribute value of the key point; if the point type of a key point is an electrical anomaly area point, the text value corresponding to the name of the electrical anomaly area where the electrical anomaly area point is located is determined as the attribute value of the key point. The attribute value of the key point; if the point type of a key point is a sinkhole point, then the text value corresponding to the name of the sinkhole where the sinkhole point is located is determined as the attribute value of the key point; if the point type of a key point is a geophysical anomaly area point, then the text value corresponding to the name of the geophysical anomaly area where the geophysical anomaly area point is located is determined as the attribute value of the key point; if the point type of a key point is a well field boundary point, then the text value corresponding to the name of the well field boundary where the well field boundary point is located is determined as the attribute value of the key point; if the point type of a key point is a village range point, then the text value corresponding to the name of the village range where the village range point is located is determined as the attribute value of the key point; if the point type of a key point is a protective coal pillar point, then the text value corresponding to the name of the protective coal pillar where the protective coal pillar point is located is determined as the attribute value of the key point; if the point type of a key point is a river point, then the text value corresponding to the name of the river where the river point is located is determined as the attribute value of the key point.

[0118] In the embodiment of the present invention, after the attribute value of each key point is obtained, the attribute value of each key point is stored in a CSV file.

[0119] It should be noted that, as mentioned above, the position information of each key point on the curve trajectory is stored in a CSV file, the point type information of each key point is stored in a CSV file, and the attribute value of each key point is stored in a CSV file. The CSV files they store are the same CSV file. In an embodiment of the present invention, all the above data can be saved in a specified CSV file.

[0120] In a specific embodiment, Figure 5An example diagram of the CSV file format provided by an embodiment of the present invention is shown. A CSV file is a text file with a CSV extension in which columns are separated by commas. A CSV file that meets the requirements includes 4 columns. The first column is "serial number", which is the number of key points selected in the present invention; the second column is "distance from the starting point", which must be a numerical value, which is the location information of each key point in the present invention; the third column is "attribute value"; the fourth column is "point type"; the first line is the title row, which will be ignored when imported into CAD.

[0121] In step S104, the profile parameters are determined, and the drilling profile is automatically drawn according to the profile parameters, location information, point type and attribute values ​​to obtain a drilling profile.

[0122] In a specific embodiment, the profile parameters can be determined by designing a DCL dialog box. Figure 6 The schematic diagram of the DCL dialog box for setting profile parameters provided by the embodiment of the present invention is shown. It can be understood that the DCL dialog box can provide a friendly interactive interface, and the determined profile parameters can be checked intuitively. If there are errors, they can be revised again, which greatly reduces the probability of misoperation.

[0123] Optionally, in one embodiment, the profile parameters in the above step S104 include: increased distance on the left side of the profile, increased distance on the right side of the profile, starting elevation of the profile, ending elevation of the profile, profile line spacing and annotation font height.

[0124] Optionally, in one embodiment, the above step S104 may include:

[0125] Specify the drawing base point.

[0126] Based on the drawing base point, the section parameters, location information, point type and attribute value are automatically drawn to obtain the basic section graphics.

[0127] The basic profile figure is processed by connecting contour points, drawing stratum structure or drawing fault structure to obtain a borehole profile.

[0128] In the embodiment of the present invention, the drawing base point is the starting point of the drawn cross-section basic figure, which can be manually specified.

[0129] In the embodiment of the present invention, automatic drawing is performed based on the drawing base point according to the section parameters, position information, point type and attribute value to obtain the basic section figure, which can be specifically: automatic calculation is performed based on the section parameters, position information, point type and attribute value, and the section grid is drawn based on the drawing base point, the elevation is marked, and the obtained position information, point type and attribute value are drawn on the section map in different colors according to different attributes, the starting point, end point and contour point of the curve trajectory are automatically drawn with auxiliary lines according to the corresponding elevations and the data are marked, which can be deleted after later verification, the longitude and latitude points are automatically marked, and auxiliary lines are automatically drawn for key points such as fault points and lane points, Figure 7 An example diagram of a basic profile of directional drilling automatically generated according to an embodiment of the present invention is shown.

[0130] In the embodiment of the present invention, the basic profile graphic is processed by connecting contour points, drawing stratum structure or drawing fault structure, and the specific process of obtaining the borehole profile can be: connecting the automatically marked contour points into line segments, offsetting the line segments according to the stratum thickness to obtain the stratum structure, drawing the fault structure, and then filling the stratum according to the lithology, and finally trimming and beautifying the graphic, deleting redundant marks, adding a frame and a label, and obtaining a perfect profile graphic. It can be understood that Figure 8 An example diagram of a perfectly processed directional drilling profile provided by an embodiment of the present invention is shown.

[0131] In one embodiment, it should be noted that errors may occur during the execution of all the above steps. When an error occurs, operations such as displaying an error message, closing file reading and writing (writing buffer data to a file and releasing file occupation), setting the current color to follow the layer, opening a command line prompt, restoring object snap settings, terminating all DCL dialog boxes, and deleting temporary DCL files can be performed. The specific implementation code is as follows:

[0132]

[0133]

[0134] From the above, it can be seen that the present invention can first obtain relevant data from the CAD graphics of the curve trajectory, and then convert the data into a CAD profile graphic. The implementation method adopts the AutoLISP language, and the relevant data can also be stored in a CSV file for comparison and inspection to see whether the basic profile graphic is correctly generated. If the generated profile graphic is incorrect, the data in the CSV file can be directly modified, and then the data in the CSV file can be imported to automatically generate the basic profile graphic. The DCL dialog box can also be designed to provide a friendly user interaction interface to improve the user experience, and finally realize the automatic drawing method of the curve trajectory directional drilling profile.
