辽中凹陷古近系东营组高精度层序地层及沉积体系分析
High-Resolution Sequence Stratigraphy and Depositional System Analysis of Dongying Formation, Paleogene in Liaozhong Depression
摘要
Abstract
Based on seismic, logging, drilling, palynology, micropalaeontology and other geologic information, the strata of Dongying Formation in Liaozhong Depression is divided into 3 3rd-order strata sequences which system tract is divided accurately. Dongying Formation is divided into 7 4th-order strata sequences by means of regression turbidite fan basal interface which is traced readily. Based on identifying the core,log curve and seismic feature, all kinds of depositional system, such as sublacustrine fan, subsea apron,fan delta, braided channel delta, meandering river delta, beach-bar etc, are identified. It is concluded that depositional system is dominated by strata sequence, sedimentary derivation, denivellation, break of slope and tectonic movement.关键词
