Optimal drilling trajectory prediction method of lateral well

The invention relates to the technical field of exploration and development of oil and gas fields, in particular to an optimal drilling trajectory prediction method of a lateral well. The method includes the steps of acquiring a rock three-dimensional dynamics parameter field through conversion of dynamic static rock dynamics; determining natural fracture systems and occurrence distribution through core palaeomagnetic orientation, imaging logging and array acoustic logging; conducting present stress field simulation utilizing the rock three-dimensional dynamics parameter field; determining development probability of fractures of different periods utilizing acoustic emission experiments to simulate ancient stress field of different periods; simulating and determining present crustal stressvertical distribution through stress field simulation of well areas; and predicting fracturing fracture spreading directions utilizing crustal stress, fractures and vertical distribution of rock dynamics to establish an equivalent extending vertical zonation model of fracturing fractures. The optimal drilling trajectory prediction method of the lateral well verifies the reliability of fracturing fracture spreading directions by combining the drilling direction of the lateral well and dynamic materials of the lateral well, and realizes direction prediction of fracturing fractures of different blocks and optimal drilling trajectory design of the lateral well.
