缓坡坡折带——箕状断陷的精华

Slow slope fold belt——the soul of half graben rift

箕状断陷是一种常见的含油气陆相沉积单元。地域广阔的斜坡是简单箕状断陷油气运移的主要指向 ,发育着构造、岩性、地层等多种多样的油气藏。在总结箕状断陷规律的基础上 ,认为坡折带是箕状断陷缓坡重要的成藏带 ,是箕状断陷的精华 ,其重要性不亚于中央隆起带 ,并阐述了缓坡坡折带的含义、地震反射特征。

The half graben rift is one of the common continental sedimental unit of oil & gas. Widespread slope is the main oil & gas migration direction of simple half graben rift, where developed various hydrocarbon reservoirs including tectonic, lithological and stratum one. But it's a long term attention that if there is a structural belt with centralization of reservoir, such as centre uplift. By summarizing the laws of the half graben rift, this paper indicates that slope fold belt is the important reservoir belt of slow slope and the soul of the half graben rift, it's importance is not less than the centre uplift.
