Background
The sedimentary facies belt diagram is an important representation method in geological research work, and is usually used for reasonably drawing sedimentary rock facies belt lines according to a certain rule. The automatic tracking method of the deposited phase belt map is generally based on triangulation, a constraint triangular net is formed according to some constraint conditions, and phase belt line tracking is carried out on the triangular net. The automatic tracking method of the deposition phase diagram rapidly draws the deposition phase diagram through a computer technology, can liberate technicians from complicated drawing, applies more time to research, and improves the working quality and efficiency. The imaging of the sedimentary facies belt chart is mainly carried out manually in the early stage, the problems of low efficiency and the like of manually drawing the chart are more and more prominent, the production requirements of oil fields are not met, and many domestic oil fields are researched. Most of the methods adopt a triangular grid method and a grid method based on various interpolation methods, basically adopt a mathematical method as a main method to realize a phase-band line drawing method similar to an equivalent drawing method, and realize automatic drawing of a deposited phase-band diagram through computer-aided manual interpretation.

The historical research results are inherited well, and the mapping time is saved. At present, the automatic tracking method of the sedimentary facies belt map lacks a local updating mechanism, when a new well is inserted or a local area sedimentary facies is modified, the existing sedimentary facies map needs to be updated, one method is to regenerate the whole sedimentary facies map, and the other method is to interactively edit the sedimentary facies map on the original sedimentary facies map.
Both of these operations have drawbacks:
1) The whole deposition phase diagram is regenerated, the original deposition phase diagram is manually drawn or automatically generated, after new well data is added or parameters are changed, the automatically generated diagram has larger difference from the original result diagram, and the original deposition phase diagram cannot be effectively utilized.

According to the determined rectangular area, an intersection point 3 of the rectangle and the existing deposition phase belt diagram 0 is calculated, and the calculation steps are as follows:
