冀中坳陷河间南潜山油藏勘探技术

Exploration technology of Hejiannan buried hill oil reservoir in Jizhong depression

在对冀中坳陷河间南地区三维地震资料进行精细目标解释过程中 ,利用多种勘探技术和手段准确查明圈闭形态 ,对油源、储集层、封盖条件进行综合评价 ,从而发现和落实了一个新的潜山圈闭———河间南潜山。经综合论证后设计钻探的M85 1井在雾迷山组获得了高产油气流。河间南潜山油藏的发现过程表明 ,潜山油田进入中后期高含水开发阶段 ,在发现新油藏的难度越来越大、资源接替矛盾日益突出的形势下 ,必须重视三维地震勘探资料采集、处理和解释技术 ,深化区域综合地质研究 ,在潜山发育带寻找富含油气的中小规模潜山油藏 ,为油田实现可持续发展提供资源保障。图 4参

During precise target interpretation to the 3-D seismic data of the Hejiannan area in Jizhong depression, a new buried hill trap- Hejiannan burial hill has been discovered after establishing trap status accurately and comprehensive evaluation on the sources, reservoir and seal by several survey technology and means. After comprehensive discussion and conformation, Well M851 was drilled and explored in the Wumishan Formation, which got high industrial oil stream. This article describes the importance of the full 3-D seismic survey technology and comprehensive geological study in the deep areas.
