南堡凹陷是一个中生代开始发育的含油气凹陷 ,经历了断陷期和坳陷期两个演化阶段 ,具幕式沉积特点。区内构造带呈环状展布 ,可分为周边凸起潜山构造带、近边或裙边构造带及凹陷中央构造带。以高柳断层为界 ,呈南北分区的格局。圈闭的形成与展布明显受构造演化控制 ,断陷期以背斜、潜山圈闭为主 ,坳陷期以各种类型的断块、断背斜圈闭居多
Nanpu depression is a petroliferous depression that began to develop in the Mesozoic. It experienced two stages of evolution and fault deposition, including episodic deposition and episodic deposition. The tectonic belts in the area are distributed in a ring shape and can be divided into buried hill structural belt, near side or skirt structure belt and central structural zone of depression. Taking the high-willow fault as the boundary, the pattern is divided into north and south. The formation and distribution of traps are obviously controlled by the tectonic evolution. The anticline and anticline faults are mainly characterized by anticlines and buried hill traps. During the depression, various types of fault blocks and anomalous discontinuous beacons occured
