【摘要】 伸展盆地中的褶皱现象是普遍的,它们可形成重要的油气圈闭。本文根据地震资料研究了濮城构造的成因类型和演化。濮城构造为与深部断裂活动和沙三段盐层有关的褶皱构造,是典型的正断层断展褶皱。褶皱幅度和沉积厚度分析证明,该褶皱的主要发育期为沙二段和沙一段沉积期。濮城构造优越的构造位置、良好的封闭条件和匹配的构造形成时间与生排烃时间,决定了其优越的成油气藏条件,未来勘探应注意裂缝性油气藏的发现。更多还原

【Abstract】 Folds are common in an extensional basin and they are important traps for oil and gas.This paper analyzes the genetic types and evolutions of the Pucheng structure based on seismic data.The Pucheng structure was a normal fault propagation fold related to deep fault activities and salt layers in the third member of Shahejie formation.The fold relief and sedimentary thicknesses indicate a fold forming time in the depositional time of the second and first members of Shahejie formation.The outstanding tectonic location,effective sealing conditions and the matching between structural formation and hydrocarbon generation and discharge indicate favorable reservoirs in the Pucheng structure.The future exploration should pay attention to fracture reservoirs.更多还原
