摘要:The structural belt in the west margin of Ordos Basin is one of the three major risk exploration fields in Changqing Oil field, which has complex geological genesis, developed faults, wide exploration fields and various reservoir types. The underground geological target is complex, the shallow high steep structure is developed, and the deep reflection characteristics are not clear; the surface sand layer is dry, with large porosity, and velocity and thickness of the underlying lithology vary greatly in vertical and horizontal directions; the imaging accuracy of high-density two-dimensional and conventional three-dimensional data is low, which is difficult to meet the requirements of multi-layer integrated three-dimensional exploration. Aiming at the problem of "double complex underground and surface" seismic imaging and acquisition cost straight-line climbing in the research area, the scheme of "wide azimuth and high-density 3D observation system+EV56 high-precision vibrator high-efficiency excitation technology+node instrument receiving" was adopted for the first time, which greatly improved the quality and acquisition efficiency of seismic data. This scheme provides seismic technology for structural lithologic target exploration in "double complex" area and guides the direction of benefit exploration.
