In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides an embodiment of a method for determining a deviation angle difference recorded by a submarine node, and referring to fig. 1, the method for determining the deviation angle difference recorded by the submarine node specifically comprises the following contents:
s101: acquiring seismic data of the sea bottom and selecting shot point data from the seismic data; performing linear correction on the shot data, and rotating three-component data in the corrected shot data to a target attitude;
in the step, the seismic data of the sea bottom are obtained, and all the shot points in the target range and the shot point data corresponding to each shot point are selected by taking the node record as the center.
The target range in this embodiment is a range with a radius of 10km to 18km with the node record as the center. It should be noted that each seismic data in the seismic data acquired from the sea bottom in this step includes a direct wave.
And correcting the three-component data in the shot point data by adopting the sound velocity in water so as to correct the direct wave of the shot point from the water layer to the node to the position of the starting moment. Further, the gather data record length may be truncated between 0ms and 200 ms.
In this step, the sound velocity in water is 1550m/s as an average sound velocity.
Further, the three-component data in the shot point data are rotated to the target posture by utilizing the angles recorded by the nodes and combining the declination of the node working area. Specifically, the Z component in the three-component data is rotated to the vertical downward direction, the X component and the Y component are rotated to the horizontal plane, and the X component points to the true north position, that is, the target posture is: the Z component is vertically downward, the X and Y components are in the horizontal plane and the X component points to true north.
S102: calculating the azimuth angle of the shot point pointing to the demodulator probe according to the shot point coordinate and the node coordinate;
s103: rotating the X component and the Y component in the shot point data of the target attitude and calculating the rotating direction angle;
in the step, an X component and a Y component in the shot point data of the target posture are extracted, and the X component and the Y component in the shot point data of the target posture are rotated clockwise; calculating root mean square values (RMS) corresponding to the X component and the Y component respectively while rotating; determining a clockwise rotation direction angle according to the root mean square value of the X component and the root mean square value of the Y component, specifically, calculating a corresponding clockwise rotation angle when the root mean square value of the X component is maximum and the root mean square value of the Y component is minimum; and determining the rotation angle as a clockwise rotation direction angle.
S104: and determining the absolute value of the direction angle and the azimuth angle as the difference value of the deviation angles recorded by the submarine nodes.
It should be noted that since two values of the clockwise angle of rotation will make the result satisfy the condition, 180 ° needs to be subtracted when the difference is greater than 180 °, and the above calculation process is repeated one by one for all shots in the selected range.
And finally, for each seabed node, storing and outputting the shot point coordinates and the deviation angle difference obtained by corresponding calculation, and displaying the shot point coordinates and the deviation angle difference in a two-dimensional plane graph mode, wherein the horizontal axis and the vertical axis are respectively XY direction plane coordinates of the shot point, the difference is expressed in a color grading mode, and the color scale range is set to be 0-30 degrees.

To further explain the scheme, the invention provides an application example of a method for determining a deviation angle difference of a record of a subsea node, which specifically comprises the following contents:

FIG. 2 is a scanned graph of deviation angle differences generated by calculation of selected nodes, and the area shown in FIG. 2 is shot points within a radius of 14km and centered on the node, and deviation angle differences recorded by the node are analyzed and divided into four segments, wherein the precision of the first segment meets the requirement, and the differences of about 7 degrees and 13 degrees exist in the subsequent three segments.
The time period is divided according to the difference value, and the recorded angle value of the subsea node in the underwater time is shown in fig. 3 by combining the angle broken line of the subsea node recorded underwater. The broken line in fig. 3 is the angle value recorded by the node under water, and from top to bottom, the angle value is Yaw, Pitch, Roll, and it can be seen from fig. 3 that the posture of the node mainly undergoes four changes under water.
Analyzing and correcting angles in each time period, extracting the shot points of the circular area with the radius of 14km again, and calculating deviation angle difference values, so that the difference values in each time period meet requirements, the angle correction result is correct, the time period division applied to correction is correct, and as shown in fig. 4, after the selected nodes in fig. 4 are subjected to segmentation analysis and correction, a deviation angle difference value scanning graph is generated through calculation. In fig. 4, the difference between the deviation angle value calculated by the shot point in each time period and the corrected deviation angle value meets the requirement, the angle correction result is correct, and the time period division applied to correction is correct.
From the above description, it can be known that the time range covered by the embodiment of the present invention is comprehensive, accurate and effective, and the condition of the angle record can be obtained integrally by observing and analyzing the obtained deviation angle value difference diagram. The standardized inspection process of the rotation analysis and correction of the submarine nodes can be formed, and the industrial production requirements can be met.
