摘要：

泌阳凹陷新庄地区油层埋藏浅、厚度大、富集程度高,油藏类型以断鼻断块油藏为主。针对新庄地区油层埋深浅、断块复杂的特点,采用了保护好浅层反射信息的三维地震勘探方法。采集上运用基于模型的设计技术而确定了小偏移距、小面元的束状观测系统;处理上注重速度分析和叠前偏移处理;解释上综合应用人机联作系统的多种功能识别断层、落实断块。解释成果用于部署探井,发现了一批含油圈闭,收到明显的效果。

Abstract:

Reservoirs in Xinzhuang area, Biyang depression, are characterized by shallow burial depth, large thickness and high enrichment, and are mainly of fault-nose and fault-block types. In view of the shallow burial depth of reservoirs and complexity of fault blocks, 3D seismic survey method that can well preserve reflected signals has been applied in Xinzhuang area. In seismic acquisition, a fasciculate observation system with short offset distance and small bin has been used. In seismic processing, stress has been put on velocity analysis and pre-stack migration. In seismic interpretation, various functions of interactive system have been integrated to identify faults and to ascertain fault blocks. A lot of oil-bearing traps have been discovered by exploration wells positioned on the basis of the interpretation results.

Key words: Biyang depression, shallow oil reservoir, enriching condition, shallow 3D seismic survey, exploration efficiency
