摘要

根据渤海南部海域新近系油田群目的层埋藏浅、地层为"泥包砂"的特点,在地震资料处理及储层描述方面提出了几项有针对性的特色技术:通过少道叠加方法提高地震资料的分辨率;通过强波峰及强波谷的关系判定地震资料极性;通过90°相移剖面快速得到拟岩性剖面;通过地层切片快速全面地评价研究区储层分布情况。这些方法简单实用,在渤南油田群储层预测中取得了很好的效果,为ODP设计和实施提供了地质依据。
According to the characteristics of shallow target formations and "sand surrounded by clay" in Neogene oilfields,the southern Bohai water,some distinctive techniques with an aim were presented in seismic data processing and reservoir description,such as improving the resolution of seismic data by stacking a few traces,discriminating the polarity of seismic data through analyzing the relationship between strong wave peak and trough,generating rapidly the pseudo-lithology profile through the 90° phase-shift sections,and evaluating quickly and completely the reservoir distribution in the study area by using the formation slices.These simple and practical techniques have made quite good effects of reservoir prediction in these oilfields,providing a geological base for their design and implementation of ODP(overall development program).
