摘要：

高5区块油气藏位于南堡凹陷高尚堡地区高北断层上升盘高5断鼻中部,在钻探开发以前,被认为是受断块控制的构造油气藏。钻探开发以后,发现其构造形态为完整的断鼻构造;物源主要来自北东方向;油层最厚的位置不在构造高部位而在断鼻的腰部;累积产油量曲线与油层等厚图形态基本一致。因此,该油气藏应是一个典型的构造背景下的岩性油气藏。油气藏主要受控于沉积作用、构造运动、成岩及后生作用。扇三角洲前缘亚相带为最有利的储集体发育带。

Abstract:

Hydrocarbon pool of Gao-5 Block is situated at the central part of fault noze structure of the upthrow of Gaobei Fault- in Nanpu Sag, Gaoshangpu area.It was considered to be structural pool controlled by fault block in the past,but it has been proved by drilling and exploration practices that the structure is a complete fault noze structure, the provenance is in the northeast,the thickest oil layer is at the waist of the noze,the curve of oil cumulative production coinsides with the isopachous figure of the oil layer. So it is considered that the pool should be a typical lithologic one controlled by sedimentation,tectonic movement, diagenesis and epigenesis.The most favourable reservoiring zone of the study area is the subfacies zone of fan-deltaic front.

Key words: hydrocarbon pool, Characteristics, controlling factor, Nanpu Sag
