| 摘 要： | 目的探索利用多波分量技术提高地震储层测精度。方法在精细岩石物理分析和岩性、流体敏感因子优选的基础上,通过PS波标定,纵横波精细对齐进行纵横波联合解释、联合反演;利用实测全波列测井数据对PS波AVO响应特征和储层及流体的关系进行定量研究。结果在研究区进行含气性预测,预测符合率较单一纵波提高10%以上。结论多波勘探技术因增加了横波信息,有效提高了岩性和流体预测精度。

| Abstract: | Aim To study the multicomponent seismic technique to enhance seismic prediction.Methods Based on detailed physical property analysis,the sensitive elastic properties for reservoir characterization is selected.The marking of PS data and matching of PP and PS data,the interpretation and joint inversion of PP and PS data is discussed.The PS AVO is thoroughly analyzed based on different types of wells.Results By combining the techniques of multicomponent seismic data,the success ratio has been increased more than 10% compared with P-wave seismic alone.Conclusion The accuracy of lithology and fluids prediction with multi-component seismic is effectively improved because PS data is available. |
