摘要：

运用地层基准面原理,通过岩芯、测井、地震资料的综合分析,在研究层段识别出短期、中期、长期三种规模的地层旋回,分别响应于不同级次的基准面旋回。在短期旋回内,识别出可容纳空间增大时的重力流水道沉积和浊流溢岸沉积、可容纳空间减少时的重力流水道沉积和水道间溢岸沉积4种相序类型;在中期旋回中,识别出进积-退积对称型、进积非对称型和退积非对称型,指出在不同的基准面旋回位置,发育不同类型的中、短期旋回。通过对比,建立了该区二维高分辨率层序地层格架,并对前梨园洼陷南部有利储层发育层段及成油条件提出了新的认识。

Abstract:

Based on the principle of base level,three scales of stratigraphic cycles(short term, intermediate term and long term)could be identified through the analysis of cores,logs and seismic data.The stratigraphic cycles correspond respectively to different order base level cycles. Different types of facies successions occurred in different positions of the base level cycles. In light of the identification of multi order base level cycles,2 D high resolution sequence stratigraphic framework is established.Finally,a new proposal about favorable reservoir formations and hydrocarbon generation conditions in Qianliyuan Depression have been proposed.
