松辽盆地南部西部斜坡区坳陷期湖盆底形演化特征
|
摘要
根据地震、钻井、岩心及测井资料,将松辽盆地南部西部斜坡区青山口组三段—嫩江组一段划分为青三层序、姚家层序和嫩一层序。在层序地层等时格架的基础上,应用回剥法经去压实和古水深校正,对西部斜坡区湖盆底形特征进行了恢复。研究结果表明,西部斜坡区坳陷期湖盆坡折带的发育程度受控于盆地的差异沉降以及沉积物供给速率,随着大地热流值的逐渐降低,湖盆坡折越来越不明显;而坡折带的发育程度对盆地的充填序列和沉积格局有着重要影响。其中,青三层序坡折带发育明显,湖盆表现为深水坳陷沉积;姚家层序坡折发育不明显,表现为宽浅氧化湖盆;嫩一层序湖盆底形平缓,受湖侵影响,表现为广阔深水湖盆。
Based on seismic, drilling, core and logging data, the sequence stratigraphy framework of Member 3 of Qingshankou FormationMember 1 of Nenjiang Formation of the west slope zone in southern Songliao Basin is divided into SQqn3, SQy, and SQn1. Using the isochronous stratigraphy framework, backstripping inversion, paleoburial depth reconstruction and paleobathymetric correction techniques, the paleogeomorphology of the western slope zone is rebuilt. It can be concluded that the maturity of the basin slope during the depression period of the western slope zone is controlled by the differential subsidence and the rate of sediment supply. With the gradual decline of geothermal heat flow, the slope break could not be seen clearly, but the maturity of the slope zone exerts great effect on the filling sequence and sedimentary pattern of the basin. The slope break is very obvious and the lake basin is a deep water depression in SQqn3. The lake basin is shallow and oxidized and the slope break could not been seen clearly in SQy. The bottom of lake basin is smooth and deep-water deposits developed widely in SQn1 due to lake transgression.
