[0030] Step S101, obtain cable channel path information, wherein the cable channel path information contains at least one cable channel main path and at least one cable channel sub-path, and one cable channel main path contains at least one must-pass point.

[0031] Step S102, according to the position information of the at least one must-pass point, adopt a preset first division strategy to perform first path division on the at least one cable channel main path, to obtain at least one main path set.

[0032] In this step, the first position of a first must-pass point and the second position of a second must-pass point are obtained, a circle is constructed with the distance between the first position and the second position as the diameter, and each cable channel main path covered by the circle is divided into the same main path set, wherein the first must-pass point and the second must-pass point are any two must-pass points in the at least one must-pass point.

[0033] Step S103, select a target main path set from the at least one main path set according to a preset selection strategy, and determine the first positioning interval of the well according to the target main path set.

[0034] In this step, the number of cable channel main paths in each main path set is obtained, the main path set with the largest number of cable channel main paths is selected from the at least one main path set, and is defined as the target main path set; the first plane layout map of each target cable channel main path in the target main path set is obtained; the first plane layout map is set on a preset two-dimensional coordinate system, the coordinate information of the must-pass points on each target cable channel main path in the first plane layout map is determined according to the two-dimensional coordinate system; the coordinate information of each must-pass point is clustered to obtain a first center point, the must-pass point closest to the first center point is defined as a first target must-pass point, and the first positioning interval of the well is determined with the first target must-pass point as the positioning interval center and a preset distance as the radius.

[0035] Step S104, perform second path division on the at least one cable channel sub-path according to a preset second division strategy, to obtain at least one sub-path set.

[0036] ​In this step, a cable channel main path connected with at least one cable channel sub-path is acquired, and the at least one cable channel sub-path is divided into a corresponding sub-path set according to a main path set to which the cable channel main path belongs, to obtain at least one sub-path set, wherein the cable channel main paths connected with each cable channel sub-path in a sub-path set are in the same main path set.

[0037] In step S105, a target sub-path set is selected from the at least one sub-path set according to the selection strategy, and a second positioning interval of the work well is determined according to the target sub-path set.
