Method for dissecting braided river reservoir structure by utilizing discontinuous boundary of seismic reservoir

The invention discloses a method for dissecting a braided river reservoir structure by using a discontinuous boundary of an earthquake reservoir, and relates to the technical field of rock reservoir development, and the method comprises the following steps: establishing a geological information knowledge base of a target reservoir; establishing a combined mode of a braided river deposition center beach and a river channel, and grading the braided river channel according to the scale of the river channel and the cutting degree of the center beach; extracting a discontinuous boundary A and a discontinuous boundary B according to seismic 90-degree phase shift data in seismic data; performing forward modeling to obtain a discrimination standard of the discontinuous boundary A and the discontinuous boundary B; and according to the discontinuous boundary A, the discontinuous boundary B, the actual drilling thickness of the target reservoir, the geological mode and the seismic data, dissecting the target reservoir s
