层序地层学在齐家北地区的应用

摘要
以层序地层学的原理为指导,从地震层序、测井曲线、沉积层序分析入手,对泉头组三段至青山口组二、三段层序地层格架进行了研究,划分出3个三级层序,并划分出了体系域,确立了地层格架。其中,层序Ⅰ相当于泉头组三段至青山口组二、三段下部地层,发育低水位体系域、水进体系域和高水位体系域,是一个完整的旋回;层序Ⅱ代表的是青山口组二、三段中部沉积,低水位体系域不发育,只发育水进体系域和高水位体系域;层序Ⅲ代表青山口组二、三段中上部地层,与层序Ⅱ有相似特征。
Based on theory of sequence stritigraphy, this paper analyzes seismic sequence, logging curves and sedimentary sequence, studies formation framework from Member 3 in Quantou Formation to Member 2 and 3 in Qingshankou Formation. It divides them into three 3-level sequences, divides reef limestone, and determines formation framework. Sequence I corresponds to formation from Member 3 in Quantou Formation to lower part of Member 2 and 3 in Qingshankou Formation, developing low water level reef limestone, water transgression system domain and high water level system domain, being a complete cycle. Sequence II corresponds to middle part of Member 2 and 3 in Qingshangkou Formation, only developing water transgression system domain and high water level system domain and without low water level system domain. Sequence III corresponds to upper part of Member 2 and 3 in Qingshankou Formation, with similar characteristics with Sequence II.
