摘要
近年来,我国对湖湘地区重力流的研究逐渐深入,但对于四川盆地侏罗系的相关研究相对较为有限。在川东南涪陵地区的TY1井中,发现了侏罗统凉高山组中半深湖-深湖的重力流沉积。以TY1井的岩心数据为基础,结合深水重力流沉积的相关理论,对这一套重力流形成的沉积岩进行了深入研究,包括沉积构造和垂向组合等方面。这项研究在一定程度上丰富了对四川盆地侏罗系湖盆深水重力流沉积的认识,对于预测非常规储层具有重要的意义。
In recent years,research on gravity flows in the Hu-Xiang region of China has been progressively advancing.However,studies related to the Jurassic system in the Sichuan Basin have been relatively limited.In the TY1 well located in the Fuling area of southeastern Sichuan,gravity flow deposits of the Middle Jurassic Lianggaoshan Formation,characterized as semi-deep to deep lake environments,have been identified.This paper,based on the core data from well TY1 and incorporating relevant theories on deep-water gravity flow deposits,conducts an in-depth study of the sedimentary rocks formed by this set of gravity flows,including sedimentary structures and vertical associations.This research,to a certain extent,enriches our understanding of deep-water gravity flow deposits in the Jurassic basin of the Sichuan Basin and holds significant implications for predicting unconventional reservoirs.
