Method of intelligently drawing sedimentary face map facing oilfield exploration and development, and system of intelligently drawing sedimentary face map facing oilfield exploration and development

The embodiment of the present invention discloses a method of intelligently drawing a sedimentary face map facing the oilfield exploration and development, and a system of intelligently drawing the sedimentary face map facing the oilfield exploration and development. The method comprises the steps of obtaining the coordinate of a well point and a face value corresponding to the coordinate, and rotating and compressing the coordinate of the well point according to the flow direction of a riverway and the communication degree to generate a single well face plane distribution map; in the single well face plane distribution map, carrying out a Delauney triangulation with constraint on the well point to generate a main communication line and an auxiliary communication line; tracking a boundary along the auxiliary communication line of each face to generate a boundary polygon corresponding to each face; curving the boundary polygon corresponding to each face to generate a corresponding phase spread boundary; transforming the coordinate of the single well face plane distribution map with the phase spread boundary into an initial coordinate, and generating the corresponding sedimentary face map.
