【摘要】 讨论了流体异常压力封存箱的形成和演化特征及其对岩石中扎隙的保护作用。研究结果表明，流体异常压力封存箱对孔隙的保护作用主要概括为3个方面：①压力封存箱的存在不仅可保护次生扎隙也可以保护原生扎隙；②压力封存箱对次生扎隙的保护是有条件的；③在压力封存箱的保护下，深部地层中的孔隙，特别是次生孔隙不会很快地消失。通过对济阳拗陷下第三系中的压力封存箱与次生扎隙发育带的分析，提出了箱内的、箱缘的、箱侧的和不整合面以下与风化壳有关的4种次生扎隙发育带基本的地质模式。更多还原

【Abstract】 The formation and evolution feature of abnormally pressured fluid comartment discussed aswell as its preserving to secondary pores in rocks are discussed. The study demonstrates that thepreservations resulted from the compartment sum up three aspects as follows: ①The compartmentkeel) not only primary pore, but also secondary pore; ②It is in specific conditions that thecomparment can preserve secondary pore; ③Under protecting of the compartment, the pores in burieddeely rocks are kept from disappearing rapldly, especialy secondary pore. It is suggested that the basicgeologycal models be classified into four types: inter-compartmental, margin-compartmental, sidecompartmental seeondary pore zones and zone of secondary pore relating with weathering crust.更多还原
