喇嘛甸油田多波地震属性分析与油气预测
|
摘要
应用多波地震资料能有效解决单一纵波地震资料预测时产生多解性的问题。以大庆长垣喇嘛甸油田北北二区萨尔图油层为例,通过多波地震属性进行气层边界识别,并结合纵横波联合反演获得纵横波速度比、L_R M_R等弹性参数。储层砂岩厚度、岩性和流体预测结果与实际情况吻合很好,表明利用多波地震资料能够提高油气藏预测的可靠性和精度。
Multi-wave seismic data can effectively solve the multiple-solution problem resulted from the prediction by means of the simple P-wave data.Taking Saertu oil reservoirs in Block Beibei-2 of Daqing Lamadian Oilfield as an example,with the help of multi-wave seismic attributes,the gas-reservoir boundaries can be recognized,and moreover combined with the joint inversion of P-wave and P-SV wave,the elastic parameters such as v_P/v_S,L_R,M_R and so on are obtained.The predicted results by the reservoir sandstone thicknesses,lithologies and fluids are well accordant with the fact,that's to say the multi-wave seismic data can enhance and improve the reliability and precision of the petroleum reservoir prediction.
