通过对新地震资料的精细构造解释，结合区域地质分析表明，埕岛潜山受印支、燕山等多期构造运动的影响，发育了负反转、走滑拉张、构造调节三种断裂；紧邻古近系凹陷的负反转断裂以及与不整合面沟通的走滑拉张断裂在油气的纵向输导中起到了重要作用，构造调节断裂对油气聚集起到了侧向遮挡作用。总体上断裂体系控制了油气展布，形成了多个油气富集条带。
通過對新地震資料的精細構造解釋，結閤區域地質分析錶明，埕島潛山受印支、燕山等多期構造運動的影響，髮育瞭負反轉、走滑拉張、構造調節三種斷裂；緊鄰古近繫凹陷的負反轉斷裂以及與不整閤麵溝通的走滑拉張斷裂在油氣的縱嚮輸導中起到瞭重要作用，構造調節斷裂對油氣聚集起到瞭側嚮遮擋作用。總體上斷裂體繫控製瞭油氣展佈，形成瞭多箇油氣富集條帶。

The analysis of fine structure explanation of seismic data and regional geology shows that it is controlled by Indosinian, Yanshanian and Himalayan movements and three types of faults, including negative structur al inversio n, strike-slip extension and structural adjustion, develop in Chengdao Buried Hill. Both the negative inversion faults near the Paleogene sag and the strike-slip extensional faults communicated with unconformities play an important role in vertical hydrocarbon migration, while the structural adjustion faults act as lateral barrier for hydrocarbon accumulation. It is suggested that the fault system controls the hydrocarbon accumulation in many oil-rich zones.
