Description

Background Technology

[0002] Fault dip angle is one of the important parameters of fault geometry. By calculating the fault dip angle, we can gain a deeper understanding of the activity nature of the fault, such as normal faults, reverse faults, or strike-slip faults, and their role in crustal movement. Currently, fault dip angles are calculated using geological maps or through field measurements. However, regardless of whether calculations are performed using field measurements or geological maps, measurement errors can lead to deviations in the calculated results.

[0003] Currently, the theoretical calculation method for measuring fault dip angle using optical images of vertical borehole walls is relatively mature. Industry experts generally believe that fault dip angle parameters cannot be obtained using optical images of horizontal geological exploration borehole walls; therefore, there is no method for calculating fault dip angle using optical images of horizontal geological exploration borehole walls. Summary of the Invention

The location of feature points on the fault interface is determined based on the spatial geometric model, and the fault dip angle is calculated based on the location information of the feature points. As a further improvement of the present invention, a fault geometric model is established based on the transverse borehole wall image, specifically including: A planar geometric model is constructed based on the transverse borehole wall image, and a fault spatial geometric model is established based on the planar geometric model. Determine the spatial relative coordinate system in the fault spatial geometric model, and determine the fault interface based on the spatial relative coordinate system.

[0006] As a further improvement of the present invention, determining the location of feature points on the fault interface based on a spatial geometric model specifically includes: Based on the fault boundary line of the planar geometric model, the peak position corresponding to the shallowest hole depth in the fault boundary line is taken as the first feature point, the peak position corresponding to the deepest hole depth in the fault boundary line is taken as the second feature point, and the intersection point of the straight line connecting the first feature point and the second feature point with the fault boundary line is taken as the third feature point. Based on the spatial relative coordinate system, the fault boundary line of the planar geometric model is determined, and the positions of the three feature points in the planar geometric model are transformed to the fault boundary of the spatial geometric model.

[0007] As a further improvement of the present invention, the step of determining the fault interface by dividing the planar geometric model into fault boundaries according to the spatial relative coordinate system, and transforming the positions of three feature points in the planar geometric model to the fault interface in the spatial geometric model, specifically includes: The planar coordinates of three feature points are obtained based on the planar geometric model, and the planar coordinates include the borehole depth and roll angle. The planar coordinates of the three feature points obtained from the planar geometric model are transformed into a spatial coordinate system. The spatial relative coordinate system takes the horizontal borehole opening as the origin and the drilling direction, vertical direction, and horizontal direction as the coordinate axes.

[0008] As a further improvement of the present invention, the calculation expression for the fault interface is as follows:

[0009] In the formula, a, b, and c are intercept coefficients, which are determined based on the positions of the three feature points.

[0010] As a further improvement of the present invention, the step of calculating the fault dip angle based on the location information of the feature points specifically includes: the formula for calculating the dip angle of the fault interface is as follows:

[0011] In the formula, Let θ be the fault dip angle, and a, b, and c be the intercept coefficients, respectively.

[0012] As a further improvement of the present invention, the calculation expression for the intercept coefficient is as follows:

[0013]

[0014]

[0015] In the formula, (x1, y1, z1) are the spatial relative coordinates of the first feature point, (x2, y2, z2) are the spatial relative coordinates of the second feature point, and (x3, y3, z3) are the spatial relative coordinates of the third feature point.

[0016] Secondly, the present invention also provides a fault dip angle calculation system for implementing the above-mentioned fault dip angle calculation method, comprising: The model building module is used to build a planar geometric model based on the borehole wall image of a transverse borehole with faults. The planar geometric model includes the fault, rock strata, and fault boundaries. The spatial geometric model is also built based on the planar geometric model. The spatial geometric model includes the fault, rock strata, and fault interfaces.

[0018] Thirdly, the present invention also provides a computing device, comprising: One or more processors, a memory, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including steps in a method for performing a fault dip angle calculation.

[0019] Fourthly, the present invention also provides a computer-readable storage medium storing one or more programs, the one or more programs including instructions that, when executed by a computing device, cause the computing device to perform the above-described method for calculating the fault dip angle.

[0020] The beneficial effects of this invention are as follows: A transverse borehole is obtained underground using drilling equipment, and high-resolution camera equipment is used to record the RGB image data of the borehole wall. Specialized borehole camera equipment or a pipeline robot is used to move at a constant speed inside the borehole to ensure clear and complete images of the borehole wall. These images should cover the entire borehole wall for subsequent analysis and modeling. Using the acquired images, a three-dimensional fault geometric model, including faults, strata, and fault interfaces, is established using image processing and geological analysis software. Key feature points are identified on the fault interfaces; these feature points should have obvious geometric features or easily identifiable markers for subsequent calculations and analysis. Based on the location information of the feature points, the dip angle of the fault is calculated using geometric relationships and trigonometric functions; the dip angle is the angle between the fault plane and the horizontal plane. Establishing a fault geometric model using borehole wall images can greatly improve the accuracy of fault location and dip angle. With an accurate fault model, geologists can better understand the underground geological structure, providing important information for resource exploration and engineering planning. Accurate fault dip angle data helps assess potential geological risks in engineering projects, such as landslides and earthquakes. In oil and gas or mineral resource development, understanding the precise location and dip angle of faults helps in more effective disaster prevention and mitigation. Attached Figure Description

Detailed Implementation

[0023] To make the objectives and technical solutions of this invention clearer and easier to understand, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0024] The present invention provides a method, system, device, and medium for calculating fault dip angle, wherein the calculation method mainly includes: Acquire images of the borehole wall in the transverse borehole, and establish a spatial geometric model based on the images. The spatial geometric model includes faults, rock strata, and fault interfaces. Based on the fault interface of the spatial geometric model, the location of the feature points on the interface is determined, and the fault dip angle is calculated based on the location information of the feature points.

[0025] The spatial geometric model construction process mainly includes: A planar geometric model is constructed based on the image of the borehole wall in the transverse borehole, and a spatial geometric model is established based on the planar geometric model. Determine the spatial relative coordinate system in the spatial geometric model, and determine the fault interface based on the spatial relative coordinate system.

[0026] Based on the fault interface of the aforementioned spatial geometric model, the locations of feature points on the fault interface are determined, specifically including: Based on the fault boundary line of the planar geometric model, the peak position corresponding to the shallowest hole depth in the fault boundary line is taken as the first feature point, the peak position corresponding to the deepest hole depth in the fault boundary line is taken as the second feature point, and the intersection point of the straight line connecting the first feature point and the second feature point with the fault boundary line is taken as the third feature point. The fault interface is determined by the boundary line in the planar geometric model using a spatial relative coordinate system. The positions of three feature points in the planar geometric model are then transformed to the fault interface in the spatial geometric model. Specifically, the planar coordinates of the three feature points, including the borehole depth and roll angle, are obtained based on the planar geometric model. These planar coordinates are then transformed to a spatial coordinate system, where the spatial relative coordinate system uses the transverse borehole opening as the origin and the borehole direction, vertical direction, and horizontal direction as coordinate axes.

[0027] Furthermore, the calculation expression for the fault interface is as follows:

[0028] In the formula, a, b, and c are intercept coefficients, which are determined based on the position of the feature point.

[0029] The expression for calculating the intercept coefficient is:

[0030]

[0031]

[0032] In the formula, (x1, y1, z1) are the spatial relative coordinates of the first feature point, (x2, y2, z2) are the spatial relative coordinates of the second feature point, and (x3, y3, z3) are the spatial relative coordinates of the third feature point.

[0033] The formula for calculating the fault dip angle is:

[0034] In the formula, Let θ be the fault dip angle, and a, b, and c be the intercept coefficients, respectively.

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] Example 1 like Figures 1-7 As shown, this embodiment provides a method for calculating fault dip angle, which specifically includes the following implementation methods.

[0037] Acquire images of the borehole wall from the transverse borehole, and establish a spatial geometric model based on the images. The spatial geometric model includes faults, rock strata, and fault interfaces.

[0038] This embodiment establishes a planar geometric model of a transverse borehole wall planar image containing faults and rock strata. For example... Figure 1 The horizontal axis represents the hole depth h, which gradually increases from left to right. The vertical axis represents the roll angle, expressed in radians, with values ​​ranging from 0 to 2π, gradually increasing from bottom to top.

[0039] In this embodiment, image data acquired during lateral drilling is used to generate, as shown below. Figure 5 The image shows the borehole wall. The horizontal axis of the borehole wall image represents the borehole depth, gradually increasing from left to right. The vertical axis represents the roll angle, ranging from 0 to 2π, where π is 3.14. The roll angles 0, 0.5π, π, 1.5π, and 2π represent the top, right, bottom, left, and top of the borehole image, respectively. In this embodiment, the top and right coordinates of the image display window are defined as positive, and the bottom left corner of the image display area is the origin. The bottom left corner of the image coincides with the coordinate point (0,0), the display width is the same as the borehole depth, and the display height is 2π, or 6.28.

[0040] The hole wall image in this embodiment is as follows: Figure 5 , Figure 6 As shown in the diagram, the geological formation is divided into two strata: the left strata are a fault, and the right strata are rock strata. The two strata are separated by a fault boundary line; that is, in the planar geometric model, the left side is the fault, the right side is the geological strata, and there is a fault boundary line between the fault and the rock strata. Point A is the leftmost peak position of the fault boundary line, point B is the rightmost peak position of the fault boundary line, and point C is the intersection of line AB and the boundary line.

[0041] Points A, B, and C are then used as feature points, with A corresponding to the first feature point, B to the second, and C to the third. The coordinates of these three feature points are obtained using the planar geometric model of the borehole wall image. The coordinates of point A are (h1, θ1), point B is (h2, θ2), and point C is (h3, θ3). The coordinates of point C are calculated using the coordinates of points A and B. The planar coordinates of the planar geometric model include the borehole depth and roll angle.

[0042] according to Figure 1 The planar geometric model shown yields a spatial geometric model, where the spatial geometric model is... Figure 2 , Figure 3The mathematical model of the borehole wall in three dimensions is shown. During the conversion from a planar geometric model to a spatial geometric model, the roll angle is 0 radians above the borehole, 0.5π radians to the right, π radians below, 1.5π radians to the left, and 2π radians above. The 0 radian and 2π radian images are both directly above the borehole. The first feature point corresponds to the peak position at the shallowest borehole depth at the fault boundary, and the second feature point corresponds to the peak position at the deepest borehole depth. The intersection of the line connecting the first and second feature points with the fault boundary line is designated as the third feature point.

[0043] In this embodiment, the spatial relative coordinate system in the spatial geometric model is determined. The center of the borehole is taken as the origin, the drilling direction as the Z-axis, the vertical direction as the Y-axis, and the horizontal direction as the X-axis. The bottom, top, and right directions of the hole are respectively taken as positive, forming a system as follows: Figure 3 The coordinate system is used. Based on the spatial relative coordinate system, the boundary line in the planar geometric model is used to determine the fault interface, and the positions of the three feature points in the planar geometric model are transformed to the fault interface in the spatial geometric model.

[0044] like Figure 3 As shown, assume any point P at the fault interface i Point P is any point on the fault boundary line. i Draw a perpendicular line from point C to the Z-axis, intersecting the Z-axis at point C. Let CD be the vertical upward direction, and define ∠DCP. i For ∠Φ i , where ∠Φ i For P i Point roll angle. Then, P i The coordinate expression of a point is: x i =r*sin (θ) i ) y i =r*cos(θ) i ) z i =h i The positional expressions of the three feature points A (x1, y1, z1), B (x2, y2, z2), and C (x3, y3, z3) in the spatial relative coordinate system are as follows:

[0045]

[0046]

[0047] Furthermore, the expression for the fault boundary equation is:

[0048] In the formula, a, b, and c are the intercept coefficients, which are determined based on the three feature points.

[0049] Therefore, the expression for calculating the intercept coefficient is:

[0050]

[0051]

[0052] The formula for calculating the fault dip angle is:

[0053] In the formula, Let θ be the fault dip angle, and a, b, and c be the intercept coefficients, respectively.

[0054] in The range of values ​​is 0≤ ≤π, in fact, the dip angle of the fault in geological exploration. The range is 0≤ ≤π / 2, therefore the fault dip angle is:

[0055] In this embodiment, the dip angle is the angle between the fault interface and the horizontal plane. Establishing a spatial geometric model by directly observing and analyzing borehole wall images can significantly improve the accuracy of fault location and dip angle. Accurate fault dip angle data helps assess potential geological risks encountered in engineering projects, such as landslides and earthquakes. In oil and gas or mineral resource development, understanding the precise location and dip angle of faults helps in more effectively planning drilling and extraction routes.
