松辽盆地中部含油组层序地层格架及介形类特征的响应
|
摘要
综合利用地震、测井、录井、岩心及分析资料,采用层序地层学、古生物学分析方法建立了松辽盆地中部含油组合层序地层格架,查明了介形类演化对层序地层格架的响应。松辽盆地中部含油组合相当于青山口组二三段、姚家组和嫩江组一段地层,由6个三级层序构成,青山口组二三段相当于3个三级层序,姚家组一段、二三段和嫩江组一段分别相当于1个三级层序。不同层序及不同体系域介形类的特征具有明显的响应特征。
Combined with the data on seismic, log, core and material analysis, and using the methods of sequence-stratigraphy and paleontology, the sequence-stratigraphic framework of the middle oil-bearing beds of the Songliao Basin is reconstructed, and the response of the Cypridea evolution to the sequence-stratigraphic framework is clarified. The middle oil-bearing beds corresponds to the strata of the 2nd and 3rd members of the Qingshankou Formation, the Yaojia Formation, and 1st member of the Nenjiang Formation, and consisting of 6 3-order sequences. The 2nd and 3rd members of the Qingshankou Formation correspond to 3 3-order sequences, and the 1st, 2nd—3rd members of the Yaojia Formation, and 1st Member of the Nenjiang Formation respectively correspond to one 3-order sequence. Owing to the changes in the organic evolution and the ecologic environment, the species of Cypridea were evidently changed in different sequences. In the same sequence, the expending and shrinking of the lakes resulted in the change of environment and the number of Cypridea decreasing, increasing, and again decreasing.
