The structural stress direction prediction method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, a structural stress direction prediction method provided in the embodiment of the present application is exemplarily described below by taking an execution subject as a terminal device as an example. The method may include steps 101 to 104 described below.
101. And the terminal equipment carries out ultrasonic imaging test on the drilled hole and acquires rock mass ultrasonic imaging data of the drilled hole.
Optionally, the properties of the borehole are not defined; wherein the attributes include at least one of: the bore diameter of the bore hole, the depth of the bore hole, and the integrity of the rock in the bore hole.
It can be understood that the hole diameter of the drill hole, the depth of the drill hole and the rock integrity in the drill hole are not limited, and the drill hole can be an existing old drill hole or a newly drilled drill hole according to the test requirement; the new drilling hole does not require the aperture and depth of the drilling hole and the integrity of rock in the drilling hole, so that the drilling is easier and the operation is simpler; the old drill holes are available, operation is not needed, the drill holes can be directly used for measurement, and time and labor are saved; therefore, the operation of the ultrasonic imaging test is simpler, more time-saving and labor-saving.
It can be understood that the general structural stress test (such as the hydraulic fracturing method) has strict requirements on the aperture and the depth of a drill hole, if the drill hole is broken, the hydraulic fracturing method cannot obtain effective test data, so that the test success rate is low, but the ultrasonic imaging does not limit the property of the drill hole, namely the old drill hole can meet the measurement requirement, the newly drilled drill hole can also meet the requirement, the ultrasonic imaging cannot damage the drill hole, and the drill hole can be recycled, so that the test efficiency can be improved.
102. And the terminal equipment acquires rock mass joint information of the drilled hole from the rock mass ultrasonic imaging data.
The ultrasonic imaging of the same drill hole is continuously measured according to different depths, so that one drill hole can obtain multiple groups of data, and the more the data is, the more accurate the comprehensive analysis result is.
The joint is also called a crack, is a common tectonic geological phenomenon, and refers to a small fracture structure with two sides of rock mass not having obvious displacement after the rock mass is fractured under stress, and the rock mass joint has a close relation with tectonic stress. 103. And the terminal equipment draws a joint trend rose diagram according to the rock joint information.
It will be appreciated that the joint trend rose diagram reflects how many joints are in each direction. The greater the number of joints in one direction, the longer the line segment in the one direction in the joint progression rose diagram.
104. And the terminal equipment determines the structural stress direction of the position of the drilled hole according to the joint trend rose diagram based on the Anderson stress theory.
Optionally, two first dominant joints can be found from the joint trend rose diagram, namely the first dominant joint trend with the largest number of joints and the first dominant joint trend with the largest number of joints.
The Anderson stress theory means that the direction of the maximum main structure stress is consistent with the direction of an acute angle bisector of the dominant joint trend, and the direction of the minimum main structure stress is consistent with the direction of an obtuse angle bisector of the dominant joint trend. Therefore, based on the anderson stress theory, it can be found that the direction of the maximum principal structural stress in the embodiment of the present application is consistent with the directions of the two first dominant joint strike acute angle bisectors, and the direction of the minimum principal structural stress is consistent with the directions of the two first dominant joint strike obtuse angle bisectors.
For example, as shown in fig. 2, a joint-oriented rose diagram is shown, and it can be understood that the longer the length of the line segment drawn through the center of the semicircle in the joint-oriented rose diagram, the more the number of joints in the direction is. In the joint oriented rose diagram, the lengths of the line segment indicated by the mark "201" and the line segment indicated by the mark "202" are longer than those of other line segments, so that the line segment indicated by the mark "201" and the line segment indicated by the mark "202" are two first dominant joint orientations in the joint oriented rose diagram, further, based on anderson stress theory, an acute angle bisector can be obtained, in which the maximum principal structural stress direction is the two first dominant joint orientations, the minimum principal structural stress direction is an obtuse angle bisector of the two first dominant joint orientations, that is, the mark "203" indicates the maximum principal structural stress direction, and the mark "204" indicates the minimum principal structural stress direction, wherein the direction of the maximum principal structural stress is perpendicular to the direction of the minimum principal structural stress.
In the embodiment of the application, through carrying out the ultrasonic imaging test to the drilling, acquire the rock mass ultrasonic imaging data of drilling, acquire the rock mass joint information of drilling from the rock mass ultrasonic imaging data, draw joint trend rose diagram according to rock mass joint information again, at last based on the anderson stress theory, according to joint trend rose diagram, confirm the tectonic stress direction of drilling position. In the scheme, in the prediction process of the tectonic stress direction, the rock mass joint information of the drill hole is obtained through ultrasonic imaging test, the joint trend rose diagram is drawn according to the rock mass joint information, and finally, the tectonic stress direction of the position where the drill hole is located is determined according to the joint trend rose diagram based on the Anderson stress theory.
Optionally, with reference to fig. 1, as shown in fig. 3, the step 104 may be specifically implemented by the following steps 104a to 104 b.
104a, the terminal equipment determines at least two dominant joint petals from the joint-oriented rose diagram, wherein each dominant joint petal is a petal meeting the target condition in the joint-oriented rose diagram.
Wherein the target conditions are: the number of joints in the direction with the most joints in the petals is larger than the number of joints in any direction in other non-advantageous joints.
Illustratively, as shown in fig. 2, the petal indicated by the mark "205", the petal indicated by the mark "206" and the petal indicated by the mark "207" are included in the joint trend rose diagram, the wider the petal is, the larger the change range of the joint trend is, and the longer the line segment in a certain direction in the petal is, the larger the number of the joint strips in the direction is.
For example, as shown in fig. 2, the rosegram of the joint strike shows that the number of joints in the first joint strike corresponding to the 30 ° direction is maximum, and if there are 10 joints, the petal in the first joint strike is marked as a dominant joint petal a; the joints of the second joint moving direction corresponding to the 330-degree direction are shown on the rose diagram, the joints are arranged for a plurality of times, and if 8 joints exist, the petals in the second joint moving direction are marked as dominant joints B; petals A and B are two advantageous jointing petals.
104b, the terminal equipment determines a structural stress direction according to at least two dominant joint petals based on the Anderson stress theory.
And calculating the second advantageous joint trend of each advantageous joint petal according to the direction and the number of each joint in the advantageous joint petals.
Illustratively, the direction and number of joints in a dominant joint petal are: 3 for 10 °, 2 for 15 ° and 5 for 20 °, then the second dominant joint trend in the dominant joint petals should be: (10 × 3+15 × 2+20 × 5) ÷ (3+2+5) ÷ 16 °; another advantage is that the joint direction and number in the joint petals are respectively: 3 for 320 °, 3 for 330 °, 4 for 335 °, then the second dominant joint trend in the dominant joint petals should be: (320 × 3+330 × 3+335 × 4) ÷ (3+3+4) ═ 329 °; based on the anderson stress theory, it can be concluded that the maximum structural stress direction is an acute angle bisector of two second dominant joint trends (16 ° and 329 °), and the minimum main structural stress direction is an obtuse angle bisector of two second dominant joint trends (16 ° and 329 °), which are perpendicular to each other.
In the embodiment of the present application, a second advantageous joint trend in the advantageous joint petals may also be calculated by other calculation methods, which is not limited in the embodiment of the present application.
Optionally, with reference to fig. 1, as shown in fig. 4, before the step 103, the method for predicting the structural stress direction provided in the embodiment of the present application may further include the following steps 105 to 106, and the step 103 may be specifically implemented by the following step 103 a.

Wherein the configuration data includes at least one of: structural stress test data of the target area and structural geological data of the target area; the structural data may also include other geological data, and the embodiments of the present application are not limited. The structural data refers to structural data of the target area recorded previously, and reference may be made to the related description, which is not described herein again.
106. The terminal equipment determines a first area structural stress direction range of the target area according to the structural data.
The structural stress direction range may be a direction range, or may be a direction (structural stress trend).
It can be understood that the structural stress direction range of the first region refers to an existing structural stress direction range of a target region obtained by analyzing structural data of the target region, the structural stress direction range of the first region can be obtained by respectively expanding an upper limit and a lower limit of the existing structural stress direction range by a certain number of degrees, a specific expansion range is determined according to an actual situation of the region, and the embodiment of the present application is not limited; the first region structural stress direction range is determined in order to exclude a part of the joint directions which are not in the first region structural stress direction range when the joint trend rose diagram is drawn, so that the efficiency and the accuracy of the structural stress direction prediction can be improved.
103a, the terminal equipment combines rock mass joint information and the first region structure stress direction range to draw a joint trend rose diagram.
Illustratively, the range of the direction of the tectonic stress of the first region is 10 degrees to 20 degrees, if the direction of a certain joint in the rock body joint information acquired according to ultrasonic imaging is 50 degrees, the degree is not in the range of the direction of the tectonic stress of the first region, so that the data can be judged as invalid data and is not used when the rosette of the joint trend is drawn; invalid data similar to the above are eliminated, and then the joint trend rose diagram is drawn, so that the accuracy of the direction prediction of the structural stress can be improved.
Optionally, with reference to fig. 1, as shown in fig. 5, after the step 104, the method for predicting the structural stress direction provided in the embodiment of the present application may further include the following step 107.
107. And the terminal equipment determines the structural stress direction range of a second region of the target region according to the structural stress directions of the positions of the plurality of different drill holes in the target region.
Wherein, the steps 101 to 104 are executed for different drill holes for a plurality of times, and the structural stress direction of each drill hole in the target area is obtained.
Illustratively, there are three boreholes in the target region, the formation stress direction of borehole one is 20 °, the formation stress direction of borehole two is 23 °, the formation stress direction of borehole three is 25 °, and the formation stress direction of the second region ranges from 20 ° to 25 °.
In the embodiment of the application, the structural stress direction of the target area obtained by comprehensively analyzing a plurality of drill holes in the target area is more accurate.
Optionally, with reference to fig. 4, as shown in fig. 6, before the step 107, the method for predicting the structural stress direction provided in the embodiment of the present application may further include the following steps 108 to 109, and the step 107 may be specifically implemented by the following step 107 a.
108. The terminal equipment acquires the structural data of the target area where the drill hole is located.
Wherein the configuration data includes at least one of: structural stress test data of the target area and structural geological data of the target area.
109. The terminal equipment determines a first area structural stress direction range of the target area according to the structural data.
Wherein, the description of the stress direction range of the first region structure can refer to the step 103b mentioned above
The related description of the stress direction range of the first region structure is not repeated herein.
107a, the terminal equipment combines the structural stress direction ranges of the positions of a plurality of different drill holes in the target area and the structural stress direction range of the first area to determine a structural stress direction range of the second area.
Illustratively, the structural stress direction of the first region ranges from 10 ° to 20 °, and the structural stress direction of the drilled hole in the target region is 30 °, so that the drilled hole is invalid data for predicting the structural stress direction of the target region, and needs to be excluded, and excluding a part of the invalid data can improve the accuracy of the structural stress of the target region.
It will be appreciated that, under normal circumstances, the deviation between the structural stress direction range of the first zone and the resulting structural stress direction range of the location of the plurality of different boreholes in the target zone will not be too great, and if so, consideration should be given to whether the target zone has significant geological activity, such as earthquakes, collapse, landslide, etc.
