Cluster well group borehole anti-collision design method, system and equipment

The invention provides a cluster well group borehole anti-collision design method, system and equipment, and belongs to the technical field of oil and gas development well drilling. The borehole anti-collision design method comprises the steps that cells are divided, and a list of storage space nodes is established; the depth of a deflecting point is determined, and a wellhead and a deflecting point node are stored in a confirmed list; searching and judging whether all adjacent nodes around the current node are stored in a to-be-searched list or not, calculating cost values F of the adjacent nodes, and circularly comparing the F values until nodes of a preliminary design track are obtained; and optimizing the output node trajectory, optimizing the node trajectory into a smooth curve, and outputting the smooth curve. According to the method, a new track design thought can be provided for the large platform cluster well group, the obstacle avoiding design process is simplified, and the risk of cluster well grou
