[0067] Figure 2 is a flowchart of a detection point coordinate detection method provided by an embodiment of the present application, executed by an electronic device, referring to Figure 2 The method includes the following steps.

[0068] Step 201: The electronic device acquires acoustic measurement data.

[0069] The acoustic measurement data is measured based on an acoustic device. The electronic device can acquire acoustic measurement data input by a user, or can acquire acoustic measurement data from other devices, which is not specifically limited.

[0070] Step 202: The electronic device acquires the coordinates of the detection point, the coordinates of a plurality of measurement points corresponding to the detection point, and the measurement time corresponding to each measurement point based on the acoustic measurement data.

[0071] For the coordinates of the detection point, the electronic device can calculate the coordinates of the detection point based on the acoustic measurement data through a formula, or the electronic device can acquire input coordinates of the detection point, which are calculated by a user or other devices based on the acoustic measurement data. The process of calculating the coordinates of the detection point based on the acoustic measurement data can be calculated through a method in related technologies, which is not specifically limited.

[0072] In a seismic exploration project, the number of geophones is generally multiple, and the coordinates of each geophone can be detected by the method provided in the application. In the embodiments of the application, the coordinates of any geophone are taken as an example for description.

[0073] For the coordinates of the multiple measurement points and the measurement time corresponding to each measurement point, the electronic device can directly read the coordinates of the multiple measurement points and the measurement time corresponding to each measurement point from the acoustic measurement data, and the measurement time is used to represent the time of the acoustic signal from the measurement point to the geophone and then back to the measurement point.

[0074] An acoustic measurement data collected in an OBN (Ocean Bottom Node) seismic exploration project is taken as an example for description. Referring to FIG. 1, Figure 3 , Figure 3 is a schematic diagram of an acoustic measurement operation, Figure 3 The geophones in FIG. 1 include R1, R2 and R3, 21725 in R1 (21725 / 23521) represents the line number of the geophone line, and 23521 represents the point number of the geophone. R2 (21725 / 23524) and R3 (21725 / 23527) are the same. For example, the coordinates of the geophone R2 are calculated as R2 (x0, y0) = (821862.4, 2823325.3), x0 represents the east coordinate of the geophone R2, and y0 represents the north coordinate of the geophone R2. The number of measurement points is 50, and the coordinates of the 50 measurement points can be directly read from the acoustic measurement data.

[0075] Step 203: For each measurement point, the electronic device determines the first vector offset distance corresponding to the measurement point based on the coordinates of the geophone and the coordinates of the measurement point.

[0076] For each measurement point, the electronic device determines the difference between the east coordinate of the geophone and the east coordinate of the measurement point to obtain a first difference value, determines the difference between the north coordinate of the geophone and the north coordinate of the measurement point to obtain a second difference value, determines the sum of the square of the first difference value and the square of the second difference value to obtain a first sum value, and determines the square root of the first sum value to obtain the first vector offset distance corresponding to the measurement point. The direction of the first vector offset distance is from the geophone to the measurement point.

[0077] The process can be represented by the following formula (1):

[0078]

[0079] wherein i = 1, 2, 3,..., n, n is the total number of measurement points, x i represents the east coordinate of the i th measurement point, y i represents the north coordinate of the i th measurement point, denotes the first vector offset distance corresponding to the i-th measuring point.

[0080] For example, the coordinates of the 1st measuring point are S(x1, y1) = (821815.1, 2823270.7), and the first vector offset distance corresponding to the 1st measuring point can be calculated by formula (1) as follows: meters. The calculation process of the first vector offset distance corresponding to other measuring points is the same, and will not be repeated here. See Figure 4 , Figure 4 the first vector offset distance calculated for each measuring point in Figure 3 .

[0081] Step 204: The electronic device determines the second vector offset distance corresponding to the measuring point based on the measuring time corresponding to the measuring point and the speed of sound.

[0082] The electronic device determines the product of the measuring time corresponding to the measuring point and the speed of sound to obtain a first product value, and determines half of the first product value to obtain the second vector offset distance corresponding to the measuring point. The direction of the second vector offset distance is also from the detection point to the measuring point.

[0083] This process can be represented by the following formula (2):

[0084]

[0085] where t i denotes the measuring time corresponding to the i-th measuring point, and υ denotes the speed of sound, denotes the second vector offset distance corresponding to the i-th measuring point.

[0086] For example, the measuring time corresponding to the 1st measuring point is 0.41 seconds, and the speed of sound is 340 meters / second, and the second vector offset distance corresponding to the 1st measuring point can be calculated by formula (2) as follows: meters. The calculation process of the second vector offset distance corresponding to other measuring points is the same, and will not be repeated here. See Figure 5 , Figure 5 the second vector offset distance calculated for each measuring point in Figure 3 .

[0087] Step 205: The electronic device determines the offset result corresponding to the plurality of measuring points based on the first vector offset distance and the second vector offset distance corresponding to each measuring point.

[0088] This step can be implemented by the following steps (1) to (2), including:

[0089] (1) The electronic device determines the vector offset distance difference corresponding to each measurement point based on the first vector offset distance and the second vector offset distance corresponding to each measurement point.

[0090] The electronic device determines the difference between the first vector offset distance and the second vector offset distance corresponding to each measurement point, to obtain the vector offset distance difference corresponding to each measurement point. That is, the value obtained by subtracting the second vector offset distance from the first vector offset distance corresponding to each measurement point.

[0091] The process can be represented by the following formula (3):

[0092]

[0093] wherein, represents the vector offset distance difference corresponding to the i th measurement point.

[0094] (2) The electronic device determines the offset result corresponding to the plurality of measurement points based on the vector offset distance difference corresponding to each measurement point.

[0095] The electronic device superimposes the vector offset distance difference corresponding to each measurement point to obtain the vector offset distance sum corresponding to the plurality of measurement points.

[0096] The process can be represented by the following formula (4):

[0097]

[0098] wherein, represents the vector offset distance sum corresponding to the plurality of measurement points.

[0099] The electronic device determines the absolute value of the vector offset distance sum corresponding to the plurality of measurement points to obtain the offset result corresponding to the plurality of measurement points, that is, wherein, D represents the offset result corresponding to the plurality of measurement points.

[0100] Step 206: The electronic device detects the coordinates of the detection point based on the offset result corresponding to the plurality of measurement points.

[0101] The electronic device determines the size relationship between the offset result corresponding to the plurality of measurement points and the preset threshold value, and determines whether the coordinates of the detection point are accurate according to the comparison result. The process is as follows: if the offset result corresponding to the plurality of measurement points is less than the preset threshold value, it is determined that the detection result of the coordinates of the detection point meets the requirements; if the offset result corresponding to the plurality of measurement points is not less than the preset threshold value, it is determined that the detection result of the coordinates of the detection point does not meet the requirements. The preset threshold value can be set and changed as needed, and no specific limitation is made thereto.

[0102] For example, the preset threshold value is 5 meters, and for Figure 3The vector offset difference corresponding to each measurement point is superimposed, and the absolute value is determined, and the result D is 1.72 meters. It can be seen that the final result is less than the preset threshold, which can indicate that the coordinates of the detection point are accurate. The schematic diagram can be seen in Figure 6 . Otherwise, it indicates that the coordinates of the detection point are not accurate and do not meet the requirements.

[0103] It should be noted that the acoustic positioning method can meet the requirements of the seabed earthquake on the accuracy of the coordinates of the detection point in theory, but in the actual operation process, the speed of the positioning ship, the performance of the acoustic equipment or other factors will cause the coordinates of the detection point calculated finally to be inaccurate. The first arrival wave secondary positioning (especially seabed node seismic acquisition) has a certain lag in processing time and cannot detect the coordinates of the detection point calculated by the acoustic positioning method in real time. The method provided in the embodiments of the present application does not rely on the first arrival wave secondary positioning with the lag characteristic, and can directly use the acoustic measurement data and the calculated detection point result to detect the detection point result, ensure the accuracy of the coordinates of the detection point, and improve the quality of subsequent seismic imaging and the accuracy of reservoir description.

[0104] In a possible implementation, the electronic device determines the accuracy of the coordinates of the detection point. The process can be: the electronic device determines the difference between the offset result corresponding to a plurality of measurement points and the preset threshold to obtain a third difference value, and determines the ratio of the third difference value to the preset threshold. The larger the third ratio is, the higher the accuracy of the coordinates of the detection point is.

[0105] In the embodiments of the present application, if the detection result of the coordinates of the detection point does not meet the requirements, the electronic device can determine the coordinates of the detection point based on the acoustic measurement data, and then detect the coordinates of the detection point determined again until the detection result meets the requirements. Alternatively, the electronic device can also measure the acoustic measurement data by the acoustic equipment again, determine the coordinates of the detection point based on the acoustic measurement data measured again, and detect the coordinates of the detection point determined again until the detection result meets the requirements.

[0106] In the embodiments of the present application, in the case where the detection result of the coordinates of the detection point meets the requirements, the electronic device can perform seismic imaging or reservoir description based on the coordinates of the detection point. The process of the electronic device performing seismic imaging or reservoir description based on the coordinates of the detection point can be implemented by the method in the related art, which will not be described here.

[0107] The embodiment of the present application provides a detection method for a detection point coordinate, which comprises the following steps: obtaining the coordinate of the detection point, the coordinate of a measurement point and the measurement time corresponding to the measurement point based on acoustic measurement data; determining the first vector offset distance corresponding to the measurement point based on the coordinate of the detection point and the coordinate of the measurement point; determining the second vector offset distance corresponding to the measurement point based on the measurement time corresponding to the measurement point and the acoustic wave speed; determining the offset result corresponding to the plurality of measurement points based on the first vector offset distance and the second vector offset distance corresponding to the measurement point; and detecting the accuracy of the coordinate of the detection point through the offset result. Since the offset result corresponding to the plurality of measurement points can reflect the offset distance size corresponding to the plurality of measurement points, the accuracy of the coordinate of the detection point can be detected through the offset result corresponding to the plurality of measurement points, and the seismic imaging is performed in the case that the coordinate of the detection point is accurate, so that the quality of the seismic imaging is improved.
