摘要:
由于郯庐断裂带的多期走滑活动,滩海地区东部的构造演化、圈闭形成过程相对复杂。通过对辽河滩海地区东部构造演化过程分析,认为研究区主要发育了3种类型的圈闭:1)前古近纪时期,潜山内幕发育了一系列近东西向的反向翘倾断块圈闭,在渐新世时期可以依靠燕南断层走滑活动接受来自东部凹陷内的油气运聚保存后成藏,形成中、古生界圈闭;2)渐新世时期,走滑作用对燕南断层进行改造,同时潜山抬升,东营组地层沿着燕南断层形成一系列断鼻圈闭;3)上新—更新世时期,研究区内发生剪切走滑作用对馆陶组地层圈闭改造,形成了馆陶组构造地层圈闭。按照有利圈闭以及经济勘探的原则,给出了建议钻探目标区域。
Abstract:
Due to the multi-stage strike-slip activity of the Tan?-Lu fault zone, the tectonic evolution and trap formation process in the eastern Liaohe offshore area are relatively complicated and the exploration has not been able to achieve a breakthrough. Based on the tectonic evolution in the eastern Liaohe offshore area, three types of traps have developed in the research area: (1)Meso-Paleozoic traps. In the Oligocene, it is possible to rely on the Yannan Fault strike-slip movement to receive hydrocarbon accumulation from the eastern sag. (2) Ed Formation traps. During the Oligocene, the Yannan Fault was reconstructed and the buried-hill was uplifted. The Ed Formation formed a series of fault-break traps along the Yannan Fault. (3) Guantao group traps. Shear strike-slip occurred in the Cenozoic research area. The stratigraphic traps of the Ng Formation were reconstructed to form structural stratigraphic traps. Finally, according to the principle of favorable traps and economic exploration, the proposed drilling target area was given, which may provide some help for the breakthrough of the exploration work in the eastern part of the offshore area.
