技术领域Technical Field
本申请涉及地球物理勘探技术领域，尤其涉及一种重磁电勘探数据处理方法及装置。The present application relates to the field of geophysical exploration technology, and in particular to a method and device for processing gravity, magnetic and electrical exploration data.
背景技术Background Art
地球物理勘探中，平面散点数据，如重磁电勘探数据一般要求每个位置只有一个数据，但由于检查点、复测点、验证点、闭合点等情况的存在，会产生一定比例的位置重复数据，这些位置重复数据指的是在一个坐标位置上有两个或两个以上的数据，并且这些重复位置在全部位置中的比例不超过30％。在数据处理中要对位置重复数据进行处理，每个坐标位置只保留一个数据，去掉该坐标位置中的其它重复数据，目前常用的方式是选用重复数据的平均值、选用第一个或最后一个数据作为该位置的唯一数据，用这种方法得到的数据，在平面异常图或平面等值线异常图中容易产生奇异点、突变点，形成的等值线不光滑，不能反映真实数据的实际情况，对后续资料处理带来不利影响。In geophysical exploration, plane scattered data, such as gravity, magneto-electric exploration data, generally require only one data at each location. However, due to the existence of checkpoints, retest points, verification points, closed points, etc., a certain proportion of position duplicate data will be generated. These position duplicate data refer to two or more data at one coordinate position, and the proportion of these duplicate positions in all positions does not exceed 30%. In data processing, position duplicate data must be processed, and only one data is retained at each coordinate position, and other duplicate data at the coordinate position are removed. The commonly used method is to select the average value of the duplicate data, select the first or last data as the only data at the position. The data obtained by this method is prone to singular points and mutation points in the plane anomaly map or plane contour anomaly map, and the contour lines formed are not smooth, which cannot reflect the actual situation of the real data, and has an adverse effect on subsequent data processing.

具体地，可以随机从所述重磁电勘探数据集中选取重磁电勘探数据，作为第一次执行所述划分步骤的目标数据；所述重磁电勘探数据与其他重磁电勘探数据之间的距离可以是两者所在坐标位置之间的距离；若存在多个与所述目标数据之间的距离不超过最小距离阈值的其他重磁电勘探数据，则将所述目标数据和多个其他重磁电勘探数据组成所述第二数据组；所述将所述目标数据划分至所述第一数据组可以包括：判断是否存在第一数据组，若是，则从重磁电勘探数据集中提取所述目标数据并加入所述第一数据组中，否则根据所述目标数据构建所述第一数据组。Specifically, gravity, magnetic and electrical exploration data can be randomly selected from the gravity, magnetic and electrical exploration data set as target data for the first execution of the division step; the distance between the gravity, magnetic and electrical exploration data and other gravity, magnetic and electrical exploration data can be the distance between the coordinate positions of the two; if there are multiple other gravity, magnetic and electrical exploration data whose distances from the target data do not exceed a minimum distance threshold, the target data and the multiple other gravity, magnetic and electrical exploration data are combined into the second data group; dividing the target data into the first data group may include: determining whether the first data group exists, and if so, extracting the target data from the gravity, magnetic and electrical exploration data set and adding it to the first data group, otherwise constructing the first data group based on the target data.

If the target data set does not have any remaining data, the dividing step is terminated.
举例来说，所述重磁电勘探数据集中的重磁电勘探数据包括：A1、A2、A3、A4、A5、A6、A7；若与A1距离不超过最小距离阈值的是A5、A6，则将A1、A5、A6组成一组第二数据组；当前剩余数据为A2、A3、A4、A7，若A3、A4、A7中与A2距离不超过最小距离阈值的是A4，则将A2和A4组成一组第二数据组；若当前剩余数据中不存在与A3距离不超过最小距离阈值的重磁电勘探数据，则根据A3构建第一数据组，若当前剩余数据中不存在与A7距离不超过最小距离阈值的重磁电勘探数据，则将A7加入第一数据组；因此，重磁电勘探数据集划分为：第二数据组A1、A5、A6，第二数据组A2、A4，以及第一数据组A3、A7。For example, the gravity, magnetic and electrical exploration data in the gravity, magnetic and electrical exploration data set include:A1 ,A2 ,A3 ,A4 ,A5 ,A6 ,A7 ; ifA5 andA6 are at a distance fromA1 that does not exceed a minimum distance threshold, thenA1 ,A5 , andA6 are grouped into a second data group; the current remaining data areA2 ,A3 ,A4 , andA7 , if A4 is at a distance fromA2 amongA3 ,A4 , andA7 that does not exceed the minimum distance threshold, thenA2 andA4 are grouped into a second data group; if there is no gravity, magnetic and electrical exploration data at a distancefromA3 that does not exceed the minimum distance threshold in the current remaining data, then a first data group is constructed based onA3 ; if there is no gravity, magnetic and electrical exploration data at a distance fromA7 that does not exceed the minimum distance threshold in the current remaining data, then A4 is grouped into a second data group.7 is added to the first data set; therefore, the gravity, magnetic and electrical survey data set is divided into: second data sets A1 , A5 , A6 , second data sets A2 , A4 , and first data sets A3 , A7 .

S11：计算全部数据中的第一个数据分别与其它所有数据之间的空间距离，认为所有距离小于0.1米的数据位置与第一个数据的位置是同一个坐标位置，作为位置重复数据。按照该方法找到其他所有位置重复的数据，将所有位置重复的数据建立数据集A，位置不重复的数据建立数据集B。其中，若存在唯一的第二数据组，则数据集A可以相当于上述第二数据组，若存在多个第二数据组，则各个所述第二数据组可以组成数据集A；上述第一数据组可以相当于数据集B。S11: Calculate the spatial distance between the first data in all the data and all other data, and consider that the data positions with a distance less than 0.1 meters are the same coordinate position as the first data position, as position duplicate data. According to this method, find all other position duplicate data, establish data set A for all position duplicate data, and establish data set B for non-position duplicate data. If there is a unique second data group, data set A can be equivalent to the above second data group, if there are multiple second data groups, each of the second data groups can constitute data set A; the above first data group can be equivalent to data set B.
S12：将数据集A中的一个重复位置(该位置记为P)为中心，将整个平面划分为8个扇形区域，在每个扇形区域中，在数据集B中搜索出距离P最近的3～5个数据，根据反距离加权法，计算出该位置数据的预测值Vf。S12: Taking a repeated position in data set A (the position is denoted as P) as the center, the entire plane is divided into 8 sector-shaped areas. In each sector-shaped area, 3 to 5 data closest to P are searched in data set B, and the predicted value Vf of the data at that position is calculated according to the inverse distance weighted method.
S13：将位置P处的所有重复数据取平均，得到该位置重复数据的平均值Va。S13: average all repeated data at the position P to obtain an average value Va of the repeated data at the position.
S14：根据数据类型的不同以及数据间的平均距离，预设一个相对误差阈值λ，如果P处的数据预测值Vf与P处的数据平均值Va之间的相对误差小于等于λ，则选择Va作为P处的唯一数据结果，舍弃该位置其它重复数据，然后进行后续步骤S19。S14: According to the different data types and the average distance between the data, a relative error threshold λ is preset. If the relative error between the data prediction valueVf at P and the data average valueVa at P is less than or equal to λ,Va is selected as the only data result at P, and other duplicate data at this position are discarded, and then the subsequent step S19 is performed.
S15：如果P处的数据预测值Vf与P处的数据平均值Va之间的相对误差大于λ，P处的所有重复数据与预测值Vf分别计算相对误差，如果最小的相对误差小于等于λ，则选择最小相对误差的重复数据为P处的唯一数据结果，舍弃该位置其它重复数据，然后进行后续步骤S19。S15: If the relative error between the predicted value Vf of the data at P and the average value Va of the data at P is greater than λ, the relative errors of all repeated data at P and the predicted value Vf are calculated respectively. If the smallest relative error is less than or equal to λ, the repeated data with the smallest relative error is selected as the only data result at P, and other repeated data at this position are discarded, and then the subsequent step S19 is performed.
S16：如果P处的数据预测值Vf与P处的数据平均值Va之间的相对误差大于λ，P处的所有重复数据与预测值Vf分别计算相对误差，如果所有相对误差均大于λ，再次预设一个相对误差阈值△(△>λ,一般为1.5～2.0倍)。S16: If the relative error between the predicted valueVf of the data at P and the average valueVa of the data at P is greater than λ, the relative errors of all repeated data at P and the predicted valueVf are calculated respectively. If all relative errors are greater than λ, a relative error threshold △ (△>λ, generally 1.5 to 2.0 times) is preset again.
S17：如果P处的所有重复数据之间的平均相对误差小于等于△，则选择Va为P处的唯一数据结果，舍弃该位置其它重复数据，然后进行后续步骤S19。S17: If the average relative error between all repeated data at P is less than or equal to △, selectVa as the unique data result at P, discard other repeated data at this position, and then proceed to the subsequent step S19.
S18：如果P处的所有重复数据之间的平均相对误差大于△，则选择Vf为P处的唯一数据结果，舍弃该位置其它重复数据。S18: If the average relative error between all repeated data at P is greater than △, Vf is selected as the unique data result at P, and other repeated data at this position are discarded.
S19：按照步骤S12至步骤S18完成数据集A中其它位置重复数据的处理。S19: Complete the processing of duplicate data at other locations in data set A according to steps S12 to S18.
