地震地质综合解释技术在锦州20-A油藏早期评价中的应用
|
摘要
地震地质综合解释技术是地震解释技术发展的必然趋势,其核心就是地震技术与地质思路的紧密结合,以地质模式约束地震的多解性,以地震的精确性约束地质的粗放性。以渤海海域锦州20-A构造为例,从圈闭精细描述和储层预测2个方面详细介绍了地震地质综合解释技术在油藏早期评价中的应用。着重强调了地震技术与地质思路的紧密结合是实现地质体精细刻画的关键。该套技术组合在锦州20-A构造的实际应用中取得了良好的勘探效果。
The integrated seismic and geological interpretation technology is now widely used in seismic interpretation.The key of the technology is to make integrated seismic interpretation under the guidance of a geologic thinking.Geological models are adopted to constrain the multiple solutions in seismic interpretation,and the accuracy of seismic technology is fully used to constrain the wide possibility of geological interpretations.Taking the structure JZ20-A in the Bohai Sea as an example,we made detailed early evaluation of reservoir using the integrated seismic and geological interpretation technology,based on fine trap description and reservoir prediction.Close integration of seismic technology and geologic model is used in definition of a geologic body.
