摘要:

以岩相古地理学及沉积学为指导,根据渤海海域大量钻井资料,指出湖相碳酸盐岩发育受古地貌、古气候、物源供给、构造演化和基底特征等因素影响,具有孤立、局限分布的特点.模型正演结果表明,湖相碳酸盐岩地震反射具强反射或丘状反射特征.实践证明,在地质模式指导下,地震-地质综合预测湖相碳酸盐岩储层分布是可行的.该方法在渤海海域B22地区和B13地区进行应用,取得了良好效果.

关键词: 地震响应, 湖相碳酸盐岩, 储层预测, 渤海海域

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
