地震高分辨率反演和地质模拟联合预测薄储层
|
摘要
提出了一种综合运用高分辨率地震反演技术和地质模拟方法预测薄储集层的方法。首先从分析储层相对稳定性及对应的地球物理场响应问题入手,针对胜利油田民丰凹陷沙三下和沙四上亚段薄储层,研究了利用地震小波多尺度分解属性高分辨率反演虚井声波时差的技术方法。然后用该技术建立了初始地质模型,并利用储层参数约束条件、井资料和地震资料进行了储层联合反演模拟。结果表明,对3000m以上的地层,运用该技术在纵向上能够揭示单层厚度为3~8m的薄储层。
The method for prognoses of thin reservoirs by combining seismic high-resolution inversion technology and geological simulation was presented. The relative stability of reservoir and the response of geophysical field of the thin reservoir in Shahejie Formation of Minfeng Sag in Shengli Oilfield were analyzed. The inversion technologies of seismic wavelet including multi-scale decomposition and high-resolution were used to analyze the interval transit time. The primary geological model was developed. The reservoir parameters, log data and seismic data were applied to simulate the geological model and to predict the thin reservoirs of Minfeng Sag. The simulation shows that for the stratum more than 3000 meters in depth, the thin reservoirs from five meters to eight meters in thickness can be prognosticated.
