Research And Application Of Seismic Data Processing Method For High And Steep Structure In Ying - Zhong Area

Seismic data processing is an integral part of seismic exploration, and processing are applied to deal with science and technology, directly or indirectly represents this entire area seismic exploration technology. With the deepening degree of exploration, complex regional and complex reservoirs constructed exploration targets, have become the focus of geophysical exploration, in this process, seismic data processing are facing more and more challenges.YingZhong region is located in the Qaidam Basin in the South Edge of Yingxiongling, the western region Mangai depression Depression Asian region on a two tectonic belt. Yingxiongling area is the most complex area of terrain conditions, Because of its unique surface structure varied, complex features underground structure, making the regional seismic data quality is poor.In this paper, the area characteristics and adopt the concept of integration, processing and interpretation, learn from other regional data processing experience, targeted to take technical measures to address the existence of technical problems. The statics problem is the first problem area. In this paper, taking constraints chromatography statics, Using micro-logging data to be bound by the better solution in the region statics problem. Anisotropic prestack time migration technology is mainly used is based on the integral solution of the wave equation of Kirchhoff integral migration method, Through the anisotropy analysis, CRP gathers all the way NMO leveled, so underground dipping reflectors homing to the real underground location of the interface, improved spatial resolution.Thesis focused on YingZhong regions data processing features, practices and applications through the system in the work area of the three-dimensional seismic data processing process achieved good application effect.
