The maturing oil areas in eastern China have entered the exploration stage for subtle traps

in which the recognition and description of reservoir(mainly the prediction of sandbodies)is considered the key factor for successful exploration.Aiming at the various types of continental subtle traps in fault lakes

set of technologies that based on 3-D seismic exploration technology and seismo geological analysis are developed for determination of the facies

lithologies

physical properties of reservoirs

and prediction of fluids at different exploration stages.The application of the technologies in the recognition and description of the typical channel turbidite sandbodies and sandstones in Jiyang depression shows positive results.
