S404, generating and displaying a representation adjacency relation graph according to the adjacency relation among the target communicating bodies.

The adjacency graph can refer to the distribution of the object communicating bodies and the faults, the distribution can refer to the adjacency of one object communicating body with another object communicating body through the faults, and the distribution comprises the adjacency of all the object communicating bodies and all the faults. In the embodiment of the application, a minimum weighted undirected connected graph is used as an adjacency graph, wherein the weight is the Euclidean distance between a target communicating body and a fault plane.

In some embodiments, the construction of the adjacency graph is divided into two cases of an intersecting fault and a non-intersecting fault according to the intersecting fault, when the intersecting fault exists, the shortest path between all communicating bodies is searched through Dijkstra algorithm, only paths passing through one fault vertex are reserved, the minimum weighted undirected communication graph is constructed, then all sub fault vertexes are replaced by parent fault vertexes, and when the intersecting fault does not exist, the minimum weighted undirected communication graph is constructed based on the relation graph directly through the minimum spanning tree algorithm.

According to the method for confirming the connectivity of the reservoir, after the second target communication body and the first communication body are confirmed to be the same communication body, the target communication bodies adjacent to the fault plane are identified by determining projections of the same communication body on the fault planes, and the adjacent relation between the second target communication body and the first communication body is determined according to the positions of the target communication bodies in a reservoir model. Finally, a minimum weighted undirected graph is generated and displayed according to the adjacency relations, and is used as an adjacency relation graph to show the distribution situation of the target communicating body and the fault, wherein the weight is based on the Euclidean distance between the target communicating body and the fault plane, and the minimum weighted undirected graph is constructed by dividing the two different situations of the existence of the intersection fault and the nonexistence of the intersection fault, so that the connectivity between the communicating bodies is systematically evaluated and optimized.
