Fine Modeling And Application Study Of Well Seismic Joint Structure In South Four-eight Development Zone

The South four- eight development zone seismic data body acquisition time, objective layer, technical parameters for existing differences and partition block explanation, of partition block seismic and structural interpretation results according to integration and correction techniques so as to make the two seismic data, achieve energy balance, the same horizon seismic phase axis unified, integration of each block faulting and tectonic surface. Study in depth domain three-dimensional structure modeling method based on time domain structure model, the velocity field, correction section, reservoir structure. The formation of 3D fine structure modeling technology to build the 3D structure model of sandstone group level, improve the understanding of the structure of the overall target area, improve fault resolution. Through the three dimensional structure of the fine model of large displacement of directional well trajectory design technology, to determine the "section, full penetration, note" of adjustment and tapping potential of ideas. The optimization principle of the well area is determined. The preferred fault understanding clear, breaking away from the regional design of large displacement directional well large, fully tap the potential of remaining oil, recoverable reserves. Through the analysis of the effect of the initial development of directional wells, directional wells to determine compliance with the specification design of large displacement zone eight- four south.
