Referring to fig. 2, the method is applied to a terminal, which may be a mobile phone, a tablet computer, a personal computer, etc. The method comprises the following steps:

step 201, determining a plurality of first position points and a plurality of second position points.

In the embodiment of the application, the reference drilling track is designed according to the position of the oil well in the stratum, and the target drilling track is constructed according to the reference drilling track, so that the target drilling track and the reference drilling track can be arranged in the same coordinate system, the first position point is determined from the target drilling track, and the second position point is determined from the reference drilling track.

For example, as shown in fig. 3, after the reference coordinate system is constructed, the reference drilling trajectory and the target drilling trajectory are located in the reference coordinate system in the unit of meters as shown in fig. 3.

Wherein the reference coordinate system is a coordinate system established in accordance with the reference drilling trajectory and the target reference trajectory. For example, a coordinate system is established with the wellhead location as the origin of coordinates. Alternatively, the coordinate system is established in other ways.

In addition, the reference coordinate system is a three-dimensional coordinate system. For example, when a coordinate system is established, a three-dimensional coordinate system is established with the wellhead position as the origin of coordinates, the horizontal east direction as the positive x-axis direction, the horizontal south direction as the positive y-axis direction, and the vertical direction to the x-axis and the y-axis as the positive z-axis direction. Or, a three-dimensional coordinate system is formed by taking the position of the wellhead as the origin of coordinates, the horizontal northward direction as the positive direction of an x axis, the horizontal eastward direction as the positive direction of a y axis and the vertical direction and the downward direction of the x axis and the y axis as the positive direction of a z axis.

And after the coordinate system is established, acquiring a target drilling track of the target drilling track in the reference coordinate system, wherein the target drilling track is composed of a plurality of position points, sampling the target drilling track to obtain a plurality of first position points, and the acquired first position points are distributed discretely. And a reference drilling track of the reference drilling track in the reference coordinate system can be obtained, the reference drilling track is composed of a plurality of position points, the reference drilling track is sampled to obtain a plurality of second position points, and the obtained second position points are distributed discretely.

Wherein each of the acquired plurality of first location points has an x-axis coordinate, a y-axis coordinate, and a z-axis coordinate. Each of the acquired plurality of second location points has an x-axis coordinate, a y-axis coordinate, and a z-axis coordinate.

In the embodiment of the present application, the number of the acquired plurality of first position points is the same as the number of the plurality of second position points. Or the number of the acquired plurality of first position points is different from the number of the acquired plurality of second position points.

For example, the number of the acquired first position points is 150, 153, 160 or other values. The number of the acquired second position points is 150, 153, 160 or other values.

For another example, after a three-dimensional coordinate system is formed with a wellhead as the origin of coordinates, a horizontal northward direction as the positive direction of the x-axis, a horizontal eastward direction as the positive direction of the y-axis, and a vertical direction perpendicular to the x-axis and the y-axis as the positive direction of the z-axis, 153 first position points are determined from the target drilling trajectory and 153 second position points are determined from the reference drilling trajectory at intervals of 25m well depths after the target drilling trajectory in the three-dimensional coordinate system and the reference drilling trajectory in the three-dimensional coordinate system of the reference drilling trajectory are determined. The first and second position points obtained are shown in table 1:

TABLE 1

Step 202, adopting different distance algorithms to respectively obtain a first distance and a second distance between any first position point and any second position point.

In the embodiment of the application, if the matching degree between the target drilling track and the reference drilling track is to be determined, different distance algorithms are adopted to determine the distance between the acquired first position point and the acquired second position point, and the matching degree between the target drilling track and the reference drilling track is determined according to the acquired distance.

Wherein the distance algorithm is capable of determining a distance between any first location point and any second location point.

In one possible implementation, a first distance between any one of the first location points and any one of the second location points is obtained using a euclidean distance algorithm.

Wherein, adopting Euclidean distance algorithm, obtaining the first distance between any first position point and any second position point, including:

wherein d is_E(P_m，Q_n) Is a first distance, x_pmIs the x-axis coordinate, y, of the first location point_pmIs the y-axis coordinate, z, of the first location point_pmIs the z-axis coordinate, x, of the first location point_qnIs the x-axis coordinate, y, of the second location point_qnIs the y-axis coordinate, z, of the second location point_qnIs the z-axis coordinate of the second location point.

In one possible implementation, the freschel distance is defined as: delta_F(f, g) ═ inf max dist (f (α (s)), g (β (s))), α, β are continuous non-decreasing real functions; s is a curve arc length parameter, α (0) ═ β (0) ═ 0, α (1) ═ β (1) ═ 1, δ_F(f, g) is the Frechst distance between curve f and curve g.

Wherein, adopt the Freund's distance algorithm, acquire the second distance between any first position point and any second position point, include:

wherein d is_E(P_m，Q_n) Is Euclidean distance, P_mIs the m-th first position point, Q_nIs the nth second position point, D_F(P_m，Q_n) Is the fray break distance.

Step 203, determining a plurality of target distances from the plurality of second distances according to the magnitude relation between the plurality of acquired first distances and the plurality of acquired second distances.

By the above steps, a plurality of first distances and a plurality of second distances can be acquired, and the magnitude relationship between the plurality of first distances and the plurality of second distances is different, so that a plurality of target distances can be determined from the acquired plurality of second distances by comparing the magnitude relationship between the plurality of first distances and the plurality of second distances.

In a possible implementation manner, a distance array is formed by a first distance and a second distance between each first position point and a corresponding second position point, a distance array matrix is formed by a plurality of acquired distance arrays according to an arrangement sequence of the first position points from front to back and an arrangement sequence of the second position points from front to back, a minimum distance array in a current distance array and a distance array adjacent to the current distance array is determined as a target array from the last distance array according to positions of the distance arrays in the distance array matrix, a second distance included in the target array is determined as a target distance, and a next target distance is determined from the target array continuously until the first distance array in the distance arrays is reached to obtain a plurality of target distances.

In the embodiment of the application, when the plurality of first position points and the plurality of second position points are obtained through the steps, the reference drilling trajectory and the target drilling trajectory are obtained from front to back, the obtained first position points have a sequence, and the obtained second position points also have a sequence, so that after each first position point and the corresponding second position point form a distance array, the obtained distance arrays can form a distance array matrix according to the arrangement sequence of the first position points from front to back and the arrangement sequence of the second position points from front to back.

In a possible implementation manner, the first distance is a euclidean distance, and the second distance is a freschel distance, and when the freschel distance is calculated by using the above formula for calculating the freschel distance, the first distance and the second distance between each first position point and the corresponding second position point obtained in the calculation process can be determined.

For example, when the distance array is constructed in such a manner that the first distance is before and the second distance is after, the obtained distance array matrix can be represented by table 2:

TABLE 2

After the distance array matrix is obtained in the above manner, the first distance in the current distance array and the first distance in the distance array adjacent to the current distance array are compared from the last distance array of the distance array matrix according to the obtained distance array matrix, the second distance in the current distance array and the second distance in the distance array adjacent to the current distance array are compared, if the first distance in any distance array is not greater than the first distance in the adjacent distance array and the second distance in any distance array is not greater than the second distance in the adjacent distance array, then any distance array is determined to be the smallest distance array, the second distance in the smallest distance array is determined to be the target distance, and then the next target distance is determined in the above manner from the smallest distance array, and obtaining a plurality of target distances until reaching the first distance array in the plurality of distance arrays.

For example, with C_i，j＝(A_i，j，B_i，j) Represents a distance array, A_i，jIs the Euclidean distance between the ith first position point and the jth second position point, B_i，jFor the freunds distance between the ith first position point and the jth second position point, the target distance is determined in each step by: contrast distance array C_i，j、C_i-1，j、C_i，j-1，C_i-1，j-1And determining the second distance in the minimum distance array as the target distance.

In an embodiment of the present application, a plurality of target distances are obtained through the above steps, and each target distance is a shortest distance between a position point on the target drill track and a position point on the reference drill track.

Step 204, obtaining an average distance of the plurality of target distances.

After the plurality of target distances are obtained, the average distance of the plurality of target distances can be obtained, and then the matching degree of the reference drilling track and the target drilling track is determined according to the average distance.

When the average distance is obtained, the total distance of the average distances is obtained, the total number of the average distances is obtained, the ratio of the total distance to the total number is obtained, and the average distance is determined as the average distance of the target distances.

And step 205, determining the matching degree of the target drilling track and the reference drilling track according to the average distance.

Through the steps, a plurality of target distances can be obtained, and then the matching degree of the target drilling track and the reference drilling track can be determined according to the obtained target distances.

The process of obtaining the matching degree through the above mode comprises the following steps: after obtaining an average distance of the plurality of target distances, a degree of matching between the target drilling trajectory and the reference drilling trajectory can be determined based on the obtained average distance, which can represent a distance difference between the target drilling trajectory and the reference drilling trajectory.

In one possible implementation, a preset target radius of the reference drilling trajectory is obtained, and a matching degree between the target drilling trajectory and the reference drilling trajectory is determined according to the preset target radius and the average distance.

Wherein the obtained preset target radius is the target radius set when the reference drilling trajectory is designed.

In the embodiment of the application, the deviation degree between the target drilling track and the reference drilling track can be determined according to the preset target radius and the obtained average distance, and then the matching degree between the target drilling track and the reference drilling track is determined according to the determined deviation degree.

Wherein, adopt following formula, according to predetermineeing target radius and average distance, confirm the matching degree, include:
