台北凹陷温吉桑-温南地区滚动勘探开发潜力及技术对策
|
摘要
温吉桑-温南地区历经燕山、喜山运动,形成了一系列成排成带展布的断背斜、断鼻等复杂构造圈闭。受断层控制,呈东西走向的局部构造与南北展布的低位体系域辫状河三角洲砂体叠置,在温吉桑地区局部构造东西两翼发育侧缘上倾尖灭岩性油藏,在温南地区发育复杂断块油藏。在高分辨层序地层学指导下开展储层横向预测,以人机工作站为平台的全三维地震目标处理、解释及断层封堵性研究是进一步挖掘本区潜在目标的关键技术。
Wenjisang - Wennan area had experienced Yanshan and Himalayan movement, and resulted in a series of complicated structural traps such as faulted anticline and faulted nose, etc. As controlled by faults, the local structure of EW trend superimposed with SN distributed braid river delta sand of lowstand system tract. In Wenjisang area, side updip pinchout lithologic deposit had developed on the two flanks of local structure, and complicated fault block reservoir had developed in Wennan area. Reservoirs are predicted laterally under the guidance of high - resolution sequence stratigraphy. Full 3D seismic processing and interpretation and the study of fault sealing ability through interactive workstation are key technologies for further tapping the potential targets in this area.
