Zusammenfassung:The invention provides a multi-component data joint speed analysis method based on longitudinal and horizontal wave matching and belongs to the field of geophysical exploration data processing. The method comprises the following steps: multi-parameter speed analysis is performed in a longitudinal wave field and a converted wave field synchronously by using a unified reflected wave time-distance equation of a longitudinal wave field and a horizontal wave field, and realizing synchronous contrast of speed trends of longitudinal waves and horizontal waves by using the synchronous comparison of a longitudinal wave channel set and a converted wave channel set; synchronously estimating relatively accurate vertical speed ratio of the longitudinal and horizontal waves through an indicator horizon, and obtaining accurate speed fields of the longitudinal and horizontal waves through section compression, the consistency principle of the depth and cycling speed iteration. Through the method, the converted wave seismic data can be processed accurately, and a seismic profile provided with high resolution, high fidelity and high signal-to-noise ratio, and can clearly reflect construction and lithological change characteristics can be obtained.
