Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The terms "first," "second," "third," and "fourth," etc. in the description and claims of this application and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Fig. 1 is a flowchart of a deformation image determination method for a casing according to an embodiment of the present application. Referring to fig. 1, the method comprises the steps of:
step 101: the terminal obtains first running-in depth and inner diameter information of a plurality of measuring points of the casing, the first running-in depth of any measuring point is the distance between the top of the casing and the measuring point, and the first running-in depth and inner diameter information of each measuring point are obtained by measuring through a multi-arm caliper.
During a casing measurement using a multi-arm caliper, the multi-arm caliper is entered from the top of the casing, so that for each measurement point, the first run-in depth is the distance between the casing and the measurement point, for example, the distance is 182.312 meters.
The multi-arm caliper comprises a motor, a measuring arm, a centering arm, a spring, a measuring rod and a displacement sensor. When the multi-arm caliper is used for measuring the casing, the motor drives the measuring arm and the centering arm to open and close. The measuring arm is supported by the spring and moves along the inner wall of the sleeve, and when the inner wall of the sleeve is deformed, the measuring arm stretches and contracts along with the deformation of the inner wall of the sleeve, so that the measuring rod is driven to axially move. Each measuring arm corresponds to one non-contact displacement sensor, and the displacement change of each measuring arm is directly reflected to the corresponding displacement sensor.
In the measuring process, a displacement sensor of the multi-arm caliper transmits displacement information of a measuring arm to a terminal; the terminal receives the displacement information and determines the inner diameter information of the casing pipe based on the displacement information. The multi-arm caliper includes a plurality of measurement arms and, correspondingly, the inner diameter information includes the radius measured by each measurement arm.
Multi-arm caliper instruments reflect casing longitudinal and lateral deformation by measuring changes in the internal diameter of the casing. The longitudinal deformation mainly includes sleeve bending and shaft deviation; the transverse deformation is complex, and comprises ellipse deformation, diameter reduction, diameter expansion, extrusion, concave-convex deformation, irregular deformation and the like.
In this step, the data from the multi-arm caliper measurement further includes a first run-in depth for the plurality of measurement points of the casing.
Step 102: the terminal selects a first target measurement point and a second target measurement point from the plurality of measurement points.
In one possible implementation manner, the implementation manner of this step may be: the terminal directly selects a first target measuring point and a second target measuring point from a plurality of measuring points corresponding to the casing.
The terminal can select a first target measuring point and a second target measuring point based on a first penetration depth corresponding to the plurality of measuring points; correspondingly, the terminal selects a first target measuring point with the first drop depth matched with the preset drop depth from the plurality of measuring points, and selects a second target measuring point with the distance between the first drop depth and the first drop depth of the first target measuring point matched with the first distance threshold on the basis of the first distance threshold.
In this step, the preset setting depth and the first distance threshold may be set and changed as needed, which is not specifically limited in this embodiment of the present application; for example, the preset penetration depth is 150 meters, and the first distance threshold is 3 meters and 5 meters.
In another possible implementation manner, since the casing includes a plurality of casing segments, and two adjacent casing segments are connected together, this step may be implemented as follows: the terminal selects a target casing segment from the plurality of casing segments, and selects a first target measuring point and a second target measuring point from a plurality of measuring points corresponding to the target casing segment.
Correspondingly, in this step, the terminal stores the identifier of each casing segment in advance, and in response to the input of the identifier of the casing segment by the technician, the terminal determines that the casing segment corresponding to the identifier of the casing segment is the target casing segment.
For a target casing segment, if the length of the target casing segment is short, the terminal can select two measurement points located at two ends of the casing segment in the target casing segment, and the two measurement points are respectively used as a first target measurement point and a second target measurement point; if the target casing segment is long, the terminal may select the first target measurement point and the second target measurement point from the target casing segment based on the first run-in depth corresponding to the plurality of measurement points. This step is similar to the implementation manner in which the terminal directly selects the first target measurement point and the second target measurement point from the plurality of measurement points corresponding to the casing, and is not described herein again.
Step 103: and the terminal acquires a second penetration depth of the first target measuring point and a second penetration depth of the second target measuring point, wherein the second penetration depth of any target measuring point is a theoretical penetration depth of the target measuring point.
The theoretical penetration depth is the penetration depth corresponding to the target measuring point during initial installation of the casing, namely the penetration depth when the casing is not deformed.
Step 104: and the terminal determines the rotation angle of the multi-arm caliper in the process of measuring the plurality of measuring points according to the first and second running-in depths of the first target measuring point and the first and second running-in depths of the second target measuring point.
The implementation manner of the step may be: the terminal determines the rotation angle of the multi-arm caliper in the process of measuring the plurality of measuring points by adopting a first formula according to the first and second penetration depths of the first target measuring point and the first and second penetration depths of the second target measuring point;
wherein, the first formula is:
wherein θ is the rotation angle h m A first run-in depth of the first target measurement point; h is n A first run-in depth of the second target measurement point; h m A second run-in depth for the first target measurement point; h n A second run-in depth for the second target measurement point; arccos is an inverse cosine function.
For example, for a target casing segment, the difference (H) between the second run-in depth of the first target measurement point and the second run-in depth of the second target measurement point m -H n ) 374.56m, and the difference (h) between the first run-in depth of the first target measurement point and the first run-in depth of the second target measurement point measured by a multi-arm caliper m -h n ) 377.46m, θ is 7.1 °.
It should be noted that, if the rotation angle is smaller than the preset angle, which indicates that the error caused by the rotation operation of the multi-arm caliper during the measurement process to the measured inner diameter information is small, the terminal performs the operation of steps 105 and 107. For example, if the predetermined angle is 36 °, i.e., the error caused by the rotation operation of the multi-arm caliper is less than 10%, and θ is 7.1 °, θ is less than the predetermined angle, the terminal performs the subsequent operation according to the fact that the multi-arm caliper is not rotated, i.e., the terminal continues to perform the operation of step 105 and step 107.
In the embodiment of the application, since the multi-arm caliper may make the measuring arm fit to the inner wall of the casing through a rotating operation during the measuring process, the maximum rotation angle possible for the multi-arm caliper can be calculated based on the original run-in depth of the casing section and the run-in depth measured by the multi-arm caliper, so that a basis is provided for subsequently determining whether a three-dimensional deformation image of the casing can be drawn according to the method.
Step 105: and the terminal responds to the fact that the rotating angle is smaller than the preset angle, selects a target measuring arm from the plurality of measuring arms, and determines the included angle between each other measuring arm except the target measuring arm and the target measuring arm by adopting a formula II.
Wherein, the formula two is:
wherein alpha is j The included angle between the jth measuring arm and the target measuring arm is shown, and n is the number of the measuring arms of the multi-arm caliper.
For example, if n is 40 and j is 15, then α j Is 126 deg..
The terminal stores the identification of each measuring arm of the multi-arm caliper in advance; correspondingly, the implementation manner of selecting the target measurement arm from the plurality of measurement arms by the terminal may be as follows: for each measuring point, the terminal selects a measuring arm corresponding to the target identification from the plurality of measuring arms as a target measuring arm.
Wherein, the target mark can be preset by the terminal; the target measuring arm of each measuring point may be the same or different, and this is not specifically limited in this application. For example, the target identification may be 1, 10, 20.
Step 106: and the terminal determines the three-dimensional coordinate data of the plurality of measuring points based on the included angle between each other measuring arm and the target measuring arm and the first penetration depth and inner diameter information of the plurality of measuring points.
Referring to fig. 2, the terminal selects the radii measured by the multiple measuring arms of the multi-arm caliper for analysis, and the radius is taken as the vertical axis, the first penetration depth is taken as the horizontal axis, and an image of the radius changing along with the first penetration depth is drawn. Wherein, the radius has a sudden change at every distance, and the position of the sudden change is the position of the gap at the joint of two adjacent casing sections.
Wherein, the realization mode of the step comprises the following steps (1) to (4):
(1) the terminal takes the center of the top of the sleeve as an origin to establish a coordinate system, the vertical axis of the coordinate system is parallel to the sleeve, the horizontal axis of the coordinate system is perpendicular to the vertical axis, and the longitudinal axis of the coordinate system is perpendicular to the horizontal axis and the vertical axis respectively.
Wherein, because the multi-arm caliper enters from the top of the casing during the measurement of the casing using the multi-arm caliper, the terminal establishes a coordinate system with the center of the top of the casing as the origin, the coordinate system being a three-dimensional coordinate system. For example, the vertical axis is the z-axis, the horizontal axis is the x-axis, and the vertical axis is the y-axis.
(2) And the terminal takes the first penetration depth of each measuring point as the vertical axis coordinate data of the measuring point.
For example, the first penetration depth is 182312.50mm, the vertical axis coordinate data of the measurement point is Z, and Z is 182312.50 mm.
(3) And the terminal respectively determines the coordinate data of the horizontal axis and the coordinate data of the vertical axis of each measuring arm corresponding to the measuring point by adopting a formula III and a formula IV based on the included angle between each other measuring arm and the target measuring arm and the radius measured by each measuring arm.
Wherein, the formula three is:
X j ＝r ij ×cosα j
the fourth formula is:
Y j ＝r ij ×sinα j
wherein, X j For the transverse axis coordinate data, Y, corresponding to the jth measuring arm j Is the coordinate data of the longitudinal axis corresponding to the jth measuring arm, i is the coordinate data of the vertical axis of the measuring point, r ij The radius measured for the jth measuring arm; cos is a cosine function and sin is a sine function.
(4) And the terminal combines the horizontal axis coordinate data, the vertical axis coordinate data and the vertical axis coordinate data of the measuring point corresponding to each measuring arm into the three-dimensional coordinate data of the measuring point.
For example, a multi-arm caliper has 40 measurement arms, and for this first run-in depth of 182312.50mm, i.e. for a measurement point with vertical axis coordinate data Z of 182312.50mm, the horizontal axis coordinate data X and the vertical axis coordinate data Y for the 1 st, 10 th, 20 th, 30 th and 40 th measurement arms of the multi-arm caliper can be seen in table 1.

Step 107: and the terminal draws a three-dimensional deformation image of the sleeve based on the three-dimensional coordinate data of the plurality of measuring points.
