SYSTEMS AND METHODS FOR DETECTING SUBSURFACE FEATURES USING 3D ANGLE GATHERS

摘要

The present disclosure is directed to detecting subsurface features via a seismic survey. A system can obtain seismic data from nodes separated from each other by at least a threshold distance on a ground surface. The seismic data can include image trace data based on field trace data detected from each of the plurality of seismic data acquisition units. The system retrieves a sample interval and a parameter. The system configures a bandlimited binning function with the sampling interval and the predetermined parameter. The system applies the bandlimited binning function to a plurality of image traces of the image trace data to generate a bandlimited angle gather value for a bin in an angle gathers grid. The system generates an image based on the angle gathers grid and provides the image for display.

1. A method of detecting subsurface features via a seismic survey, comprising:
obtaining, by one or more processors of a data processing system, seismic data detected by a plurality of seismic data acquisition units separated from each other by at least a threshold distance on a ground surface, the seismic data comprising image trace data for each of the plurality of seismic data acquisition units; retrieving, by the data processing system from a binning function data structure in memory, a sampling interval and a parameter; configuring, by the data processing system, a bandlimited binning function with the sampling interval and the parameter; applying, by the data processing system, the bandlimited binning function to a plurality of image traces of the image trace data to generate a bandlimited angle gather value for a bin in an angle gathers grid; generating, by the data processing system, an image based on the angle gathers grid; and providing, by the data processing system, the image for display via a display device, the image indicating at least one of a subsurface lithological formation and a hydrocarbon deposit.
