辽河盆地牛居地区沙河街组三段沉积特征及模式
Sedimentary characteristics and patterns of Es3 Member in Shahejie Formation of Niuju area in Liaohe Basin
摘要
Abstract
Although tight sandstone gas reservoirs have been discovered in upper sub-member of Es3 Member in Shahejie Formation of Niuju area in Liaohe Basin,exploration and development progress is restricted by deep burial of middle and lower Es3 Member and insufficient drilling data.Sequence stratigraphic framework is established via seismic sedimentology technique,dividing Shahejie Formation into 3 third-order sequence boundaries and 2 third-order sequences.Sedimentary patterns and evolution law are accurately delineated by integrating cores,logging and seismic data and applying phase conversion,frequency division interpretation and strata slicing techniques.The re-sults indicate 2 types of sedimentary patterns in Es3 Member of Shahejie Formation in Niuju area including fan del-taic-lacustrine pattern and braided river deltaic-lacustrine pattern.Simultaneously,evolution processes of these two sedimentary patterns are analyzed,and deltaic sedimentary system of upper,middle and lower sub-members of Es3 Member is improved.The research provides guidance for future oil and gas development.关键词
