摘要
东部老油田的勘探开发程度较高,主要含油气构造都已基本落实。要实现油田持续发展,依据油田周边找油田、油田深层找油田的勘探思路,必须加快探索针对复杂地表的富油区(大型城市、油田矿区等勘探禁区)勘探技术。根据近几年在冀中地区针对大型城市、矿区开展的三维地震勘探技术攻关工作,通过充分归纳总结,初步形成了一套针对大型城市、矿区的高精度三维勘探技术:基于复杂地表和深层目标的特观设计技术、基于高精度卫星照片的观测系统优化实施技术、近地表障碍物调查技术、城市地震勘探激发技术等,为类似地表区进行地震勘探提供技术参考。
The old oilfields in the east are in high degree of exploration and development,so the major oil and gas bearing structures have been basically implemented there.To realize sustainable development of oilfields,it is critical to accelerate the development of exploration techniques adaptable to the rich-zone in complex surface area,depending on the exploration thought of discovering oilfields in the surrounding area and deep zones of oilfields. According to the 3D seismic exploration techniques conducted in the urban area and oilfields in Jizhong area,through thorough induction and summarization, a set of high-precision 3D exploration techniques have been preliminarily developed.The special designing techniques based on complex surface and deep targets,the optimizing techniques of observation systems based on high-precision satellite photographs,the near-surface obstacles investigating techniques,and the excitation techniques for urban seismic exploration can be good technical reference to the seismic exploration in similar surface area.
