垦东凸起受到东部郯庐断裂带长期活动影响,呈现出复杂的构造特征。在郯庐断裂带内部,由于断层的活动火山发生多期喷发,行程了一条北北东走向的火成岩墙,通过分析发现火成岩墙形成的时间较晚,没有对该研究区古近系早期的地层发育起到主要影响作用,但对断层的活动及油气运聚、油气成藏起到重要作用,为莱州湾凹陷的古近系油气聚集成藏提供有效圈闭,同时对莱州湾凹陷所生的油气向西部的垦东凸起方向运移起到了一定的阻碍作用。
Kendong bulges are affected by the long-term activities of the Tan-Lu fault zone in the east and show complicated structural features. Within the Tan-Lu fault zone, due to the multi-phase eruption of the active volcanoes of the fault, a north-north-east igneous igneous wall was traveled. It was found by analysis that the igneous wall was formed later than the early Paleogene strata in the study area But it plays an important role in fault activity and hydrocarbon migration and accumulation, hydrocarbon accumulation, providing effective traps for the accumulation and accumulation of Paleogene hydrocarbon in the Laizhouwan Sag, Oil and gas to the west of Kendong convex direction of transport has played a certain role in hindering.
