摘要： 盐构造是由于岩盐和其他蒸发岩的流动形变所形成的地质体。世界上大约有60%的含油气圈闭与盐构造有关。在地震和探井资料基础上, 以渤海湾盆地济阳坳陷东营凹陷中央隆起带一盐构造为切入点, 探讨了该构造的物质基础和动力之源, 并将其发育分成3个阶段: 发育初期、发展期和稳定期。同时, 分析了该盐构造发育对沉积地层的影响, 指出盐构造形成后的外形与当时地质历史时期的气候有一定关系, 该地区的气候在盐构造稳定后向干旱期转化,与盐构造发育有关的断层破坏了油气藏的形成, 使该地区地层复杂化。盐构造的研究在国内尚不成熟, 它应是今后勘探的热点之一。

Abstract: Salt structure is a geologic body formed by flow and deformation of halite and other evaporitic rocks. About 60% petroliferous traps are associated with the salt structure in the world. This paper discusses the basic materials and dynamic source of a salt structure of central uplift in Dongying sag of Jiyang depression, Bohai Bay basin, North China, based on seismic and drilling data, and presents three stages of the salt structural development: initial development stage, development stage and steady stage. Also, the effect of the salt structure development on sedimentary strata is analyzed. It is recognized that the configuration of the salt structure is related to the corresponding geologic climate of arid at that time; the faults related to the salt structure destroys the formation of petroleum reservoir and makes the strata in this area complicated. Salt structure is not well studied in China and it should be one of focuses for petroleum exploration in the future.

Key words: salt structure, Dongying sag, stage, climate, fault
