Methods for Seismic Exploration in Super-shallow Reservoirs

In the outside of northern Biyang slope, the target zone of exploration is very shallow, where faults are grown. To ascertain the small tectonics, recognize small faults and conduct a research on lithologic interpretation, look for super-shallow reservoirs, the integration of seismic exploration and acquisition, process and interpretation and as well as the conception for designing seismic acquisition with the orientation of underground object are used to develop a new software for data processing based on a 3 dimensional acquisition and survey system for scientifically demonstrating the geologic and geophysical models. Advanced geologic interpretation method is used to implement a high precision imaging, by which the resolution is greatly raised, the quality of seismic data reflection is improved, on the basis of ensuring the signal-to-noise ratio of data acquisition, a batch of geologic shallow wells are deployed on the newly found traps. Unconformable reservoirs are first discovered with perfect show of oil and gas, the newly identified reserves and control of 2138×10 4 t reserves are achieved. The exploration field is greatly expanded in the north slope of Biyang Depression.
