[0067] Figure 2 is a flow chart of a detection point coordinate detection method provided in an embodiment of the present application, which is executed by an electronic device, see Figure 2 , the method comprising:

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

[0069] The acoustic measurement data is obtained based on the measurement of the acoustic device. The electronic device can obtain the acoustic measurement data input by the user, and can also obtain the acoustic measurement data from other devices, and there is no specific limitation on this.

[0070] Step 202: The electronic device obtains the coordinates of the detection point, the coordinates of multiple 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 through a formula based on the acoustic measurement data, or the electronic device can also obtain the coordinates of the input detection point, and the coordinates of the detection point are calculated by the user or other equipment based on the acoustic measurement data. Among them, the process of calculating the coordinates of the detection point based on the acoustic measurement data can be calculated by a method in the relevant technology, which is not specifically limited.

[0072] In a seismic exploration project, there are generally multiple detection points. The coordinates of each detection point can be detected by the method provided in the present application. In the embodiments of the present application, the coordinates of any detection point are taken as an example for explanation.

[0073] For the coordinates of multiple measurement points and the measurement time corresponding to each measurement point, the electronic device can directly read the coordinates of multiple measurement points and the measurement time corresponding to each measurement point from the acoustic measurement data. The measurement time is used to indicate the time for the acoustic signal to travel from the measurement point to the detection point and then return to the measurement point.

[0074] The following is an example of acoustic measurement data collected in an OBN (Ocean Bottom Node) seismic exploration project. Figure 3 , Figure 3 Schematic diagram of acoustic measurement operation. Figure 3 The detection points in include R 1 , R 2 and R 3 , R 1 In (21725 / 23521), 21725 indicates the number of the detection line, 23521 indicates the number of the detection point, and R 2 (21725 / 23524) and R 3 (21725 / 23527) The same is true. For example, the detection point R is obtained by calculation 2 The coordinates R 2 (x 0 ,y 0 )=(821862.4, 2823325.3), x 0 Indicates detection point R 2 The east coordinate, y 0 Indicates detection point R 2 The number of measurement points is 50, and the coordinates of these 50 measurement points can be directly read from the acoustic measurement data.

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

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

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

[0078]

[0079] Where 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, Indicates the first vector offset corresponding to the i-th measurement point.

[0080] For example, the coordinates of the first measurement point are S(x 1 ,y 1 )=(821815.1,2823270.7), then the first vector offset corresponding to the first measurement point can be calculated by formula (1): The calculation process of the first vector offset corresponding to other measurement points is similar and will not be repeated here. Figure 4 , Figure 4 For Figure 3 Schematic diagram of the first vector offset calculated for each measuring point in .

[0081] Step 204: The electronic device determines a second vector offset corresponding to the measurement point based on the measurement time and the sound wave velocity corresponding to the measurement point.

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

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

[0084]

[0085] Among them, t i represents the measurement time corresponding to the i-th measurement point, υ represents the speed of sound waves, Indicates the second vector offset corresponding to the i-th measurement point.

[0086] For example, the measurement time corresponding to the first measurement point is 0.41 seconds, and the sound wave speed is 340 meters per second. Then, the second vector offset distance corresponding to the first measurement point can be calculated by formula (2): The calculation process of the second vector offset corresponding to other measurement points is similar and will not be repeated here. Figure 5 , Figure 5 For Figure 3 Schematic diagram of the second vector offset calculated for each measuring point in .

[0087] Step 205: The electronic device determines the offset results corresponding to the multiple measurement points based on the first vector offset and the second vector offset corresponding to each measurement point.

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

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

[0090] The electronic device determines the difference between the first vector offset and the second vector offset corresponding to each measuring point, and obtains the vector offset difference corresponding to each measuring point, that is, the value obtained by subtracting the second vector offset from the first vector offset corresponding to each measuring point.

[0091] This process can be expressed by the following formula (3):

[0092]

[0093] in, Represents the vector offset difference corresponding to the i-th measurement point.

[0094] (2) The electronic device determines the offset results corresponding to the multiple measurement points based on the vector offset difference corresponding to each measurement point.

[0095] The electronic device superimposes the vector offset difference corresponding to each measuring point to obtain the sum of the vector offsets corresponding to the multiple measuring points.

[0096] This process can be expressed by the following formula (4):

[0097]

[0098] in, Indicates the sum of vector offsets corresponding to multiple measurement points.

[0099] The electronic device determines the absolute value of the sum of the vector offsets corresponding to the multiple measurement points, and obtains the offset results corresponding to the multiple measurement points, that is, Wherein, D represents the offset results corresponding to multiple measurement points.

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

[0101] The electronic device determines the magnitude relationship between the offset results corresponding to the multiple measurement points and the preset threshold, and determines whether the coordinates of the detection point are accurate based on the comparison result. The process is: if the offset results corresponding to the multiple measurement points are less than the preset threshold, it is determined that the detection result of the coordinates of the detection point meets the requirements; if the offset results corresponding to the multiple measurement points are not less than the preset threshold, it is determined that the detection result of the coordinates of the detection point does not meet the requirements. Among them, the preset threshold can be set and changed as needed, and there is no specific limitation on this.

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

[0103] One point that needs to be explained is that the acoustic positioning method can theoretically meet the requirements of seabed seismic for the accuracy of the detection point coordinates, 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 points finally calculated to be inaccurate. The first arrival wave secondary positioning (especially seabed node seismic acquisition) has a certain lag in processing time, and the coordinates of the detection points calculated by the acoustic positioning method cannot be detected in real time. The method provided in the embodiment of the present application does not need to rely on the first arrival wave secondary positioning with hysteresis characteristics, and can directly use the acoustic measurement data and the calculated detection point results to detect the detection point results, thereby ensuring the accuracy of the detection point coordinates, thereby improving 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 may be: the electronic device determines the difference between the offset results corresponding to the multiple measurement points and a preset threshold value, obtains a third difference value, and determines a ratio of the third difference value to the preset threshold value, wherein the larger the third ratio value, the higher the accuracy of the coordinates of the detection point.

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

[0106] In the embodiment of the present application, when the detection result of the coordinates of the detection points meets the requirements, the electronic device can perform seismic imaging or reservoir description based on the coordinates of the detection points. The process of the electronic device performing seismic imaging or reservoir description based on the coordinates of the detection points can be implemented by methods in the relevant technology, which will not be repeated here.

[0107] The embodiment of the present application provides a method for detecting the coordinates of a detection point. The method first obtains the coordinates of a detection point, the coordinates of a measurement point, and the measurement time corresponding to the measurement point based on acoustic measurement data, and then determines the first vector offset corresponding to the measurement point based on the coordinates of the detection point and the coordinates of the measurement point, determines the second vector offset corresponding to the measurement point based on the measurement time and the acoustic wave velocity corresponding to the measurement point, determines the offset results corresponding to multiple measurement points based on the first vector offset and the second vector offset corresponding to the measurement point, and detects the accuracy of the coordinates of the detection point through the offset results. Since the offset results corresponding to multiple measurement points can reflect the offset sizes corresponding to the multiple measurement points, the accuracy of the coordinates of the detection point can be detected through the offset results corresponding to the multiple measurement points, and seismic imaging is performed when the coordinates of the detection points are accurate, thereby improving the quality of seismic imaging.
