Abstract:

Under the guidance of lithofacies paleogeography and sedimentology,we analyzed the data of wells in the Bohai Sea waters and concluded that the development of lacustrine carbonates is influenced by factors such as paleogeomorphology,paleoclimate,provenance,tectonic evolution and basement characteristics.The lacustrine carbonates were found to distribute separately and be limited in certain areas.The results of forward modeling show that the lacustrine carbonates are characterized by strong reflection or mounded reflection.Our research proves that it is feasible to predict the distribution of lacustrine carbonate reservoirs with the integrated seismic-geological method under the guidance of geological model.This method has been successfully applied to the B22 area and the B13 area in the Bohai Sea waters.

Key words: seismic response, lacustrine carbonate rock, reservoir prediction, Bohai Sea waters
