[0010] By utilizing the above technical solution, this disclosure provides a method, apparatus, electronic device, and storage medium for drawing directional drilling trajectory profiles. Compared with existing related technologies, this disclosure uses borehole monitoring data of the actual drilling trajectory in the Ordovician limestone aquifer obtained by a borehole drilling directional instrument. Based on the borehole monitoring data, directional well design analysis software is used to obtain the borehole control parameters corresponding to any measuring point in the actual drilling trajectory. The borehole monitoring data includes well inclination angle, azimuth angle, and well depth. The borehole control parameters include at least vertical depth, apparent displacement, north value, east value, and closure distance. According to the borehole design starting point and borehole design ending point corresponding to the actual drilling trajectory, the profile line corresponding to the actual drilling trajectory is determined.

It is suitable for drawing profile diagrams corresponding to a large amount of measurement data, effectively improving drawing efficiency. This enables the analysis of the actual drilling trajectory profile projection of directional drilling in the Ordovician limestone aquifer, facilitating a direct understanding of the directional drilling position in the Ordovician limestone aquifer by staff, ensuring that the actual borehole position is at the designed target layer.

Detailed Implementation

[0015] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0016] To address the technical problem that the drawing of directional drilling trajectory profiles is typically done manually, which is labor-intensive and computationally complex, and that the accumulation of large amounts of measurement data as the exploration of the work area increases significantly, further increasing the workload and reducing efficiency, this embodiment provides a method for drawing directional drilling trajectory profiles. Figure 1 As shown, the method includes: Step 101: Obtain borehole monitoring data of the actual drilling trajectory in the Ordovician limestone aquifer based on the borehole drilling directional instrument, and obtain the borehole control parameters corresponding to any measuring point in the actual drilling trajectory based on the borehole monitoring data and directional well design analysis software.

[0017] The borehole monitoring data includes well inclination angle, azimuth angle, and well depth, while the borehole control parameters include at least vertical depth, apparent displacement, north value, east value, and closure distance.

[0018] In some embodiments, directional drilling technology is used to open directional boreholes on the ground. A drilling trajectory (borehole trajectory) with a certain forward direction is designed according to a certain azimuth, well inclination, and three-dimensional coordinates. Construction is carried out to reach the borehole design endpoint corresponding to the target location. The borehole directional drilling instrument may include a Measurement While Drilling (MWD) system, a drilling inclination meter, etc., for real-time measurement of wellbore trajectory parameters, such as well inclination angle, azimuth angle, and well depth. The drilling trajectory may be the actual wellbore spatial path formed during the actual drilling process. The borehole monitoring data may be the inclination data sequence collected by the directional instrument, which is used to invert the position of the borehole in three-dimensional space.

[0019] Correspondingly, directional well design and analysis software (such as COMPASS, WellPlan, DrillOffice, etc.) can be used to accurately calculate the borehole control parameters corresponding to any measuring point on the actual drilling trajectory based on the borehole monitoring data obtained on site, providing a precise basis for formation positioning and trajectory control.

[0020] Step 102: Determine the profile line corresponding to the actual drilling trajectory based on the borehole design start point and borehole design end point.

[0021] The profile line serves as a reference baseline for drawing a vertical profile of the actual drilling trajectory, typically a straight line in a horizontal plane. The profile diagram uses this line as the horizontal axis and the vertical depth as the vertical axis, displaying the projection of the three-dimensional path of the actual drilling trajectory in a specific direction. The direction of the profile line can reflect the main extension direction of the borehole or the direction of engineering interest (such as the coal seam advancement direction). The direction of the profile line can be determined by angles such as the coal seam advancement direction, the direction from the wellhead to the designed borehole endpoint, the direction from the wellhead to the center of the designed target area, or a fixed azimuth angle.

[0022] In some embodiments, the profile line can be a vertical plane uniquely determined by the borehole design start point and borehole design end point, and its azimuth angle can be the horizontal azimuth angle between the two points. By projecting the actual drilling trajectory onto this plane, a vertical profile diagram for engineering analysis is generated, which intuitively reflects the deviation of the borehole in the vertical and main azimuth directions, so as to analyze the trajectory deviation.

[0023] Step 103: Use the vector projection method to determine the projection length of any measuring point in the actual drilling trajectory on the profile line.

[0024] In some embodiments, based on the profile line corresponding to the actual drilling trajectory, the direction of the profile line is determined using the borehole design start point (wellhead) and borehole design end point, and a coordinate system (such as a plane rectangular projection coordinate system) is established. The three-dimensional directional drilling trajectory is orthogonally projected onto a profile line in a specified direction. The projection vector of any measuring point relative to the profile line can be obtained using the vector projection method, and the projection length of any measuring point in the actual drilling trajectory on the profile line can be solved using the vector projection formula. Specifically, based on the different vectors corresponding to the borehole design start point and borehole design end point of the actual drilling trajectory relative to the profile line, the projection vector of any measuring point on the profile line can be obtained. Finally, based on the projection vector, the projection length of each arbitrary measuring point on the profile line, such as the horizontal projection length, is obtained to provide the horizontal coordinate parameter in the profile diagram, which facilitates the drawing of the profile diagram corresponding to the actual drilling trajectory and the analysis of the relationship between the borehole and the formation.

[0025] Step 104: Based on the projected length of any measuring point on the profile line and the vertical depth of any measuring point, draw the profile corresponding to the actual drilling trajectory based on the borehole design starting point.

[0026] A cross-sectional view can refer to a two-dimensional graphic formed by projecting the borehole trajectory and stratum information in three-dimensional space onto a vertical plane in a specific direction. This graphic can be constructed based on a two-dimensional rectangular coordinate system (such as the cross-sectional view coordinate system). In this coordinate system, the horizontal axis can represent the projected length of any measuring point (the distance along the cross-sectional line), and the vertical axis can represent the vertical depth of any measuring point (the vertical depth from the ground surface to that point), thus intuitively showing the spatial relationship between the borehole and the stratum.

[0027] For example, a profile coordinate system can be established first, with the wellhead corresponding to the actual drilling trajectory as the origin. In this coordinate system, the horizontal axis (X-axis) represents the projected length, i.e., the projected distance of any measuring point along the profile line from the wellhead. The vertical axis (Y-axis) represents the vertical depth, i.e., the vertical depth of any measuring point, which can be automatically calculated by COMPASS. The ground surface can be set to 0 when plotting. Based on the projected length and vertical depth of any measuring point, the corresponding points are marked in the coordinate system, and then these points are connected sequentially using straight line segments to form a polyline graph representing the drilling trajectory. Specifically, various tools can be used to draw the profile, such as EXCEL, MATLAB, Python (matplotlib library), CAD, etc. After the graph is completed using these tools, data can be checked to see if it accurately reflects the changing trend of the drilling trajectory. In this way, no manual drawing is required, reducing the workload of profile drawing. It is suitable for drawing profiles corresponding to a large amount of measurement data, effectively improving drawing efficiency.

[0028] By applying the technical solution of this disclosure embodiment, this embodiment can determine the profile line based on the borehole design starting point and borehole design ending point corresponding to the actual drilling trajectory. Using the vector projection method, any measuring point in the actual drilling trajectory is projected onto the same profile line to determine the projection length of any measuring point in the actual drilling trajectory on the profile line. Then, based on the projection length and vertical depth of any measuring point, a profile diagram is drawn. This eliminates the need for manual drawing based on a large amount of measurement data, reducing the workload of profile diagram drawing. It is suitable for drawing profile diagrams corresponding to a large amount of measurement data, effectively improving drawing efficiency. It realizes the profile projection analysis of the actual drilling trajectory of directional drilling in the Ordovician limestone aquifer, making it easier for staff to intuitively understand the position of the directional drilling in the Ordovician limestone aquifer, so as to ensure that the actual position of the borehole is in the design target layer.

[0029] Furthermore, as a refinement and extension of the specific implementation of the above embodiments, in order to fully illustrate the implementation of this embodiment, step 101 may optionally include: when directional drilling is carried out in the Ordovician limestone aquifer, the well inclination angle and azimuth angle of any measuring point in the actual drilling trajectory are obtained by using a directional drilling instrument, and the well depth of any measuring point is obtained by measuring the length of the drill pipe; the borehole control parameters of any measuring point are obtained by using the directional trajectory design software COMPASS based on the well inclination angle, azimuth angle and well depth.

[0030] In some embodiments, to ensure the treatment effect, it is necessary to draw a profile diagram based on directional parameters to accurately control the directional drilling trajectory. To achieve the drawing of the profile diagram, this embodiment proposes a method for drawing directional drilling trajectory profile diagrams based on vector projection, and utilizes the powerful calculation functions of EXCEL to automate the drawing of the profile diagram. For example, Figure 2 The diagram shows the actual drilling trajectory and planar projection of directional drilling. The cube in the diagram represents an underground space, and the blue curve represents the actual drilling trajectory (the actual borehole path), which curves downward from the wellhead. The red curve represents the projected trajectory in the profile view, which is a two-dimensional projection of the actual drilling trajectory in a specific direction. The orange dashed line (design azimuth line) represents the direction of the profile line, i.e., the reference direction used for projection. Specifically, during directional drilling, the inclination angle α and azimuth angle Φ of any measuring point can be obtained through the MWD directional instrument. The well depth L parameter can be obtained by measuring the drill pipe length. The borehole control parameters can be calculated based on the above directional parameters, usually automatically calculated using COMPASS, such as vertical depth H, apparent displacement D, north value N, east value E, and closure distance C.

[0031] Optionally, step 103 may specifically include: constructing a Cartesian projection coordinate system corresponding to the profile line based on the geodetic origin, with due east as the positive x-axis and due north as the positive y-axis; obtaining the wellhead projection coordinates of the borehole design starting point in the Cartesian projection coordinate system, and the end point projection coordinates of the borehole design ending point in the Cartesian projection coordinate system; determining the projection coordinates of any measuring point in the Cartesian projection coordinate system based on the wellhead projection coordinates and borehole monitoring data of any measuring point; and determining the projection length of the projection coordinates on the translated profile line using a vector projection method, based on the projection coordinates of any measuring point, the wellhead projection coordinates, and the end point projection coordinates.

[0032] In some embodiments, a plane rectangular projection coordinate system can be established with the geodetic origin as the origin O, the east direction as the positive x-axis direction, and the north direction as the positive y-axis direction. This system is used to solve for the projected length of any measuring point on the profile line in the actual drilling trajectory. Then, based on the wellhead and borehole design endpoint in the actual drilling trajectory, the wellhead projection coordinates and endpoint projection coordinates in the plane rectangular projection coordinate system are determined.

[0033] For example, the wellhead can refer to the starting position of the borehole on the ground surface, which is the starting point of the entire borehole trajectory. All trajectory calculations are based on this. The wellhead projection coordinates A on the plane can include the coordinate values ​​of the wellhead in the plane rectangular projection coordinate system, which can be expressed as: The projection coordinates B of the borehole design endpoint on the plane can be expressed as: .

[0034] Among them, an arbitrary measuring point can refer to a measuring point distributed along the actual drilling trajectory (drilling trajectory). Its measurement data can usually be collected by the measurement while drilling (MWD) system at certain intervals. The measurement data of each measuring point can record information such as well inclination angle, azimuth angle and well depth. The projected coordinates of an arbitrary measuring point can be the two-dimensional rectangular coordinates obtained by projecting the position of the Earth's curved surface corresponding to the actual drilling trajectory onto a plane through mathematical methods, so as to facilitate the work of coal mine directional drilling, geological modeling and engineering design.

[0035] In some embodiments, when the wellhead projection coordinates A are known... By combining the East value E and North value N of any measuring point (any point D') on the actual drilling trajectory calculated using COMPASS software, the coordinates of the projection point D of D' on the actual drilling trajectory in the plane coordinate system can be calculated. That is, the projected coordinates of any measuring point D' in the plane rectangular projection coordinate system.

[0036] Optionally, using a vector projection method, the projection length of the projection coordinates on the translated profile line is determined based on the projection coordinates of any measuring point, the wellhead projection coordinates, and the endpoint projection coordinates. Specifically, this may include: translating the profile line in a plane rectangular projection coordinate system so that the translated profile line passes through the endpoint projection coordinates; drawing a first perpendicular line to the translated profile line through the wellhead projection coordinates, and obtaining the first perpendicular point between the first perpendicular line and the translated profile line; drawing a second perpendicular line to the translated profile line through the projection coordinates of any measuring point, and obtaining the second perpendicular point between the second perpendicular line and the translated profile line; and determining the projection length of the projection coordinates of any measuring point on the translated profile line based on the perpendicular vectors with the first and second perpendicular points as the starting and ending points, respectively.

[0037] For example, such as Figure 3 The diagram shows a schematic of a Cartesian projection coordinate system, with the geodetic origin at point O and the east direction as the coordinate system's origin. x The positive direction of the axis is north. y Establish a plane rectangular projection coordinate system along the positive axis. Given the wellhead's projected coordinates A on the plane... The endpoint of the borehole design is projected onto the plane at coordinate B. Section lines and x The included angle of the axis is α When the translated section line passes through point B, the first perpendicular line to the translated section line is drawn through point A. The first perpendicular line intersects the translated section line at the first perpendicular point (point C), which serves as the projection reference point. Then, a perpendicular line to CB is drawn through any measured point D, which is the second perpendicular line. The second perpendicular point (point E) between the second perpendicular line and the translated section line is obtained. The perpendicular vector from the first perpendicular point to the second perpendicular point is then... The length of the vector is the vector from the first hammer point to any measuring point. The projected length on the section line.

[0038] Optionally, before determining the projection length of the projected coordinates on the translated profile line based on the perpendicular vectors of the first perpendicular point and the second perpendicular point, the method of this embodiment may further include: obtaining a first vector with the first perpendicular point and the wellhead projection coordinates as the starting point and the ending point, respectively, and a second vector with the first perpendicular point and the ending point projection coordinates as the starting point and the ending point, respectively; determining the coordinates of the first perpendicular point based on the perpendicular relationship between the first vector and the second vector, and the angle between the profile line and the horizontal axis in the plane rectangular projection coordinate system.

[0039] In some embodiments, a first vector pointing from the first vertical point C to the wellhead projection coordinate point A can be obtained. And the second vector pointing from the first perpendicular point C to the final projected coordinate point B. Furthermore, since the first vector and the second vector are perpendicular, this perpendicular relationship, along with the section line and... x The tangent function of the angle between the axes is used to establish the solution function for the coordinates of the first perpendicular point, thus obtaining the coordinates of the first perpendicular point.

[0040] For example, suppose the coordinates of point C are... ,but , satisfy: (1); Depend on ⊥ ,Right now ,Right now: (2); At the same time, according to the cross-section lines and x The included angle of the axis is α get: (3); Combining equations (2) and (3), the formula for determining the coordinates of point C can be expressed as: (4); In the formula, x 0 may have two solutions, which can be calculated separately and then applied to the planar diagram. x 0 and x 1. x The size relationship of 2 is determined x The unique solution for 0 is used as the coordinates of the first perpendicular point.

[0041] Optionally, based on the perpendicular vectors with the first and second perpendicular points as the starting and ending points respectively, the projected length of the projected coordinates of any measuring point on the translated profile line is determined. Specifically, this may include: obtaining a third vector with the coordinates of the first perpendicular point and the projected coordinates of any measuring point as the starting and ending points respectively, and a fourth vector with the projected coordinates of any measuring point and the second perpendicular point as the starting and ending points respectively; obtaining the ratio of the perpendicular vector to the second vector based on the vector relationship between the perpendicular vector and the third and fourth vectors, and the perpendicular relationship between the fourth vector and the perpendicular vector; and determining the projected length of the projected coordinates of any measuring point on the translated profile line based on the ratio and the second vector.

[0042] For example, such as Figure 3 As shown, the third vector can be obtained from the projection point D of the first perpendicular point C to any measuring point. And the fourth vector pointing from projection point D to the second perpendicular point E. In the right triangle formed by points C, D, and E, we can obtain... , ⊥ Furthermore, CE and CB are collinear, and the relationship between the vectors can be established by combining the expressions of the vectors to obtain the perpendicular vector. With the second vector ratio t The calculation formula is then used. Finally, based on the product of this ratio and the second vector, the projected length of point D, the projection point of any measuring point, on the translated profile line is obtained. d .

[0043] The formula for calculating the projected coordinates of any measuring point D' in the Cartesian projection coordinate system is as follows: (5); In some embodiments, the projected length of point D, the projection point of any measuring point, on the translated profile line is... d The solution process is as follows: The coordinates of point C are calculated using equation (4). When the coordinates of B and D are known, then , satisfy: (6); Since CE and CB are collinear, satisfy: (7); In the formula, t for exist The projected length on and The ratio of .

[0044] In ΔCDE, Combining equations (6) and (7), we get: (8); because ⊥ ,but =0, that is: (9); Calculated from equation (9) t satisfy: (10); Right now Projected length on the translated section line d satisfy: (11); Given the coordinates of point A Coordinates of point B Coordinates of point D and section lines and x When the included angle α of the axes is given, the projected length of any point D' on the actual drilling trajectory on the profile line can be obtained by combining equations (4) and (11). Considering the complexity of the above formulas, the powerful calculation function of EXCEL can be used for auxiliary calculation.

[0045] Optionally, step 104 may specifically include: constructing a profile coordinate system corresponding to the profile line by taking the wellhead projection coordinates as the origin; determining the profile coordinates of any measuring point in the profile coordinate system based on the projection length of any measuring point on the profile line and the vertical depth of any measuring point; generating coordinate points corresponding to the profile coordinates using a preset data processing tool; importing the coordinate points in batches into a preset profile design tool, and generating a profile corresponding to the actual drilling trajectory using the preset profile design tool based on the polyline drawing command.

[0046] The profile coordinates may include the coordinates of any measuring point in the profile coordinate system (projected length). d Vertical depth - H Preset data processing tools may include spreadsheet software EXCEL, which is used to calculate the projected coordinates of any measuring point on the profile view. Preset profile design tools may include CAD, etc.

[0047] In some embodiments, such as Figure 4 The diagram shows a schematic of the cross-sectional view coordinate system. The wellhead projection coordinates can be used as the origin O (0, 0) of the cross-sectional view coordinate system, with the horizontal axis... x The vertical axis (Y-axis) represents the projected length of any measuring point on the profile line, and the vertical depth (H) of any measuring point can be negative. yThe value is used to obtain the plotted cross-section, which is used to visualize the trajectory segment.

[0048] Specifically, with the wellhead projection coordinates as the origin (0, 0), the horizontal projection length is... d for x Value, -H is y The value is generated in Excel using the "d&" and "&-H"=" functions. d To draw a section view, use coordinate points (H-series coordinate points), copy the coordinate points, select a polyline in CAD, and paste the coordinate points into the CAD dialog box. Figure 5 As shown, a directional trajectory profile diagram is displayed. The actual drilling trajectory on a two-dimensional plane shows the spatial path of directional drilling (such as horizontal wells and cluster wells) in the formation. The drilling stages can be divided into the vertical section, the build-up section, and the horizontal section. The end point of the main borehole can be the end position of the main wellbore, that is, the position where the build-up section ends and the horizontal section begins. The end point of the branch borehole indicates the possible multi-branch well structure, that is, a lateral branch well branching off from the main wellbore.

[0049] As one possible implementation, a new worksheet can be created in Excel, and the following data can be entered: Column A: any measurement point number, Column B: the projected length of any measurement point, and Column C: the vertical depth of any measurement point. Then, select the data in columns B and C, click "Scatter Plot" -> "Scatter Plot with Straight Lines" in the "Insert" menu, and adjust the chart format as needed, including adding a title and axis labels, to generate a profile diagram corresponding to the actual drilling trajectory. The profile diagram can intuitively display the relative position of the actual drilling trajectory and the Ordovician limestone aquifer, enabling profile projection analysis of the directional drilling trajectory, effectively improving drawing efficiency, and ensuring that the actual borehole position is at the designed target layer.

[0050] Optionally, the method in this embodiment may further include: when using a borehole drilling directional instrument to perform directional drilling in the Ordovician limestone aquifer, determining whether the actual drilling endpoint of the actual drilling trajectory conforms to the borehole design endpoint based on the cross-sectional diagram corresponding to the actual drilling trajectory.

[0051] The borehole design endpoint is determined based on the drilling requirements. The positional relationship between the actual drilling trajectory endpoint and the borehole design endpoint can be observed through the cross-sectional diagram. It can be checked whether the vertical depth of the actual drilling trajectory endpoint is close to the vertical depth of the borehole design endpoint, and whether the azimuth of the actual drilling trajectory endpoint is consistent with the borehole design endpoint. If there is a significant deviation, it indicates that a directional deviation has occurred during drilling. By combining the data comparison results of vertical depth, horizontal displacement, and azimuth, a comprehensive evaluation can be made to determine whether the actual drilling trajectory endpoint has reached the borehole design endpoint corresponding to the expected design target. If the deviation is found to exceed the acceptable range, the cause of the deviation (such as changes in formation conditions, equipment failure, etc.) can be analyzed, and remedial measures can be taken (such as adjusting the subsequent drilling plan, re-drilling, etc.) to ensure that the actual position of the borehole is in the design target layer.

[0052] As one possible implementation method, directional drilling can be used to treat the Ordovician limestone aquifer at the bottom of the coal seam. During the directional drilling process of each branch hole, the well depth L and well inclination angle can be obtained based on the directional data. α Azimuth Φ The parameters such as well depth, inclination angle, azimuth angle, vertical depth, apparent displacement, north value, east value, closure distance, closure azimuth, and dogleg degree are obtained by using COMPASS.

[0053] For example, taking the Z2-1 branch borehole for surface area treatment of Ordos limestone water hazard in a certain mine as an example, based on the measured wellhead coordinates A as... The north value N and east value E corresponding to any measuring point D' on the actual drilling trajectory are calculated by the directional trajectory design software COMPASS. The coordinate values ​​of any measuring point D' projected onto the horizontal plane on the actual drilling trajectory can be calculated using equation (5). The calculation results are shown in Table 1.

[0054] Table 1. Planar projection coordinates of the actual drilling trajectory

[0055] To ensure the grouting layer of the branch well is within the target layer, a cross-sectional view of the branch well needs to be drawn during drilling, with the cross-sectional line aligned with the coal seam advancement direction. The translated cross-sectional line is moved past the endpoint B of the actual drilling trajectory plane projection, and a perpendicular line is drawn from A to the translated cross-sectional line, with the foot of the perpendicular at C.

[0056] With the geodetic datum as the origin of the coordinate system, and due east as the coordinate system origin, the coordinate system originates from the geodetic datum. x The positive direction of the axis is north. y Establish a Cartesian projection coordinate system along the positive axis. Given the coordinates of point A as... The coordinates of point B are Section lines and x The included angle between the axes is 57.4°. According to equation (4), the coordinates of point C are calculated as follows: Given the coordinates of B and C and the planar projection coordinates D of the actual drilling trajectory, the projection length of any point D' on the actual drilling trajectory on the profile line is calculated using equation (11). The calculation results are shown in Table 2.

[0057] Table 2 Calculation results of the projected length of the actual drilling trajectory on the profile line

[0058] Compared with related technologies, the embodiments of this disclosure can construct a plane rectangular projection coordinate system corresponding to the profile line based on the geodetic origin, with the east direction as the positive x-axis and the north direction as the positive y-axis. Based on the projection coordinates of any measuring point, the wellhead projection coordinates, and the endpoint projection coordinates, the projection length of the projection coordinates on the translated profile line is determined. Then, with the wellhead projection coordinates as the origin, a profile diagram coordinate system corresponding to the profile line is constructed. Based on the projection length and vertical depth of any measuring point, the profile coordinates of any measuring point in the profile diagram coordinate system are determined. These profile coordinates are then imported in batches into a preset profile design tool. Based on the polyline drawing command, the preset profile design tool generates a profile diagram corresponding to the actual drilling trajectory, intuitively displaying the position of the directional drilling in the Ordovician limestone aquifer.
