Application of Seismic Prediction Technique on Complex Lithological Reservoir in SL Oilfeild

Abstract

In recent years, the proven reserves of lithological reservoirs account for a little more than two-thirds of the total proven reserves in SL Oilfield. The seismic predication technique as the key exploration method of lithological reservoirs focuses on identifying and describing reservoirs, especially on sand bodies. For the lacustrine faulted basin with various complex lithological reservoirs, based on the different geological characteristics of the reservoirs, a series of techniques suitable for channel sand, sandy conglomerate, turbidite and beach bar reservoirs have been developed and applied in the lithological reservoir identification and description and have made great progress in the actual exploration.PrefaceSince 1990s, the exploration in SL Oilfield has already developed to that of subtle reservoirs. The proven reserves of lithological reservoirs account for nearly 70% of the total reserves. The seismic predication technique as the key exploration method of lithological reservoirs focuses on identifying and describing reservoirs, especially on sand bodies. For lithological reservoir exploration in complex geologic conditions, lots of studies have been completed in order to obtain great success in many areas [1-7]. With the increasing degree of exploration, lithological reservoirs will become the key role in the future. It is very important to apply geophysical data for identification and description of lithological reservoirs. It has significant effect to improve exploration benefit and the production.
