冲绳海槽中部无井区速度场建立及应用
Establish and application of the velocity field in the middle Okinawa Trough of Non-well area
摘要
Abstract
Establishing the velocity field is necessary for in-depth study of the central Okinawa Trough. In this pa-per, two-dimensional seismic data of the no-well deep-water area in the middle Okinawa Trough were selected for the study. The stacking velocity data during processing of seismic data were obtained as the raw velocity data. By establishing the layer model and exception speed identification removal, using the Dix formula approach speed conver-sion and interpolation along the velocity, the velocity field was established in the study area. The establishment of the velocity field from the macro-regional concept, provides speed information for the central Okinawa trough. By complet-ing the variable velocity mapping, it uses geological information to reflect the subsea construction.关键词
