辽东湾海域锦州A-1钻孔重力航磁异常地层的归属及其油气勘探意义
|
摘要
简述渤海湾盆地锦州A-1井新近系明化镇组、馆陶组和古近系东营组地层特征的基础上,对基底地层归属进行了讨论。根据希指蕨孢属高含量的孢粉组合面貌,过井剖面地震反射特征,岩电性特征及周边JZB-1井,JZC-1井的地层对比,认为其应属中生界白垩系。本次基底重力异常、航磁异常地层的发现揭示了辽东湾地区与传统认识不同的潜山,证实辽东湾地区潜山也存在较好的盖层,丰富了辽东湾地区中生界储盖组合及成藏模式。
The JZA-1 well is located in the northern part of the Liaodong Uplift, Bohai Basin. A uniquely high gravity and low magnetism series was recorded in this well. Based on lithostratigraphic correlation, paleontological data, seismic sections, and wiring logs, it is suggested that this series is of Cretaceous age. The gravity and magnetism anomaly data reveal a non-traditional buried hill in Liaodong Bay, which can also be regarded as effective capping beds. This study expands our knowledge about models of oil and gas formation in the Mesozoic rocks in Liaodong Bay.
