渤海湾盆地辽东湾地区东二层序高位三角洲沉积特征
|
摘要
从岩性、电性、沉积序列及沉积构造、粒度、地震反射及储层特征等方面对辽东湾地区东二层序高位体系域三角洲储集体进行了系统的研究。三角洲前缘亚相主要发育水下分支河道、水下分流间湾、河口坝、远砂坝和席状砂5种微相。三角洲沉积的展布特征纵向上受控于构造演化,平面上受控于构造格局和古地貌形态等因素。在平面上预测出辽东湾北部、辽西凸起中南段和辽西凹陷西斜坡带为有利勘探区带,纵向上东二层序高位体系域三角洲前缘水下分支河道和河口坝砂体为优质储层。
Based on analysis of the data of borehole, well-logging, cores, palaeophyte, depositional sequence, sedimentary structure, grain size, seismic reflection and reservoir characters, systematic research was made on sedimentary characteristic of the highstand delta of Dong'er sequence,Liaodong Bay,Bohai Basin. Underwater branch channel, submarine distributary interchannal, mouth bar,distal bar and sheet sand were developed in the delta front. Laterally, the distribution characteristics of the delta were controlled by structural framework and palaeogeomorphology, and vertically, were controlled by structural evolution. The northern part of Liaodong Bay, middle and southern part of Liaoxi Uplift, and the western slope of west Liaohe Depression, are the favorable exploration plays. The high quality reservoirs include the sandbodies of underwater branch channels and mouth bar in high-stand system tract.
