高密度三维地震采集技术在高尚堡油田的应用
|
摘要
随着对老油田勘探开发程度的不断深入,常规地震勘探已经难以满足对微构造、薄互层、精细油藏描述等问题研究的需要,对地震资料的信噪比、分辨率和保真度方面提出了更高的要求。为了满足精细勘探开发的需要,2007年冀东油田在高南地区进行了40 km2高密度空间采样三维地震采集,重点对面元尺寸、覆盖次数和组合基距的选择进行了研究,通过采集处理攻关,获取的地震资料较原三维地震资料品质有大幅度提高,尤其在分辨率方面效果更显著,资料的频带展宽了25 Hz左右。为该区的深化勘探、开发工作奠定了坚实的基础。
With exploration advancing in old oil fields,conventional seismic exploration cannot fulfill the requirements for exploration of micro-structure,thin interbed,fine reservoir description,and futher requirement for signal noise ratio,resolving capability and fidelity have been proposed.In order to fulfill the requirements for fine exploration,40 km2 high density three-dimensional seismic acquisition was deployed in Gaoshangpu and Nanpu Oilfield.In the seismic acquisition,selection of bin parameters,covering degree and array length were studied.From advanced analysis and researching,the seismic data achieved was improved greatly,especially in resolving capability.The frequency range has been expanded by 25 Hz.The work will be a solid foundation for exploration and development for this area.
