【摘要】：针对生屑滩相储层非均质性强、常规物探技术及方法难以准确预测其储层和物性这一难题,研究形成了一套集"平剖融合"地震微相分析、相控储层反演、相控孔隙度预测等于一体的生屑滩相储层及物性预测方法流程和关键技术。结果表明:以波形聚类为基础的平面沉积相解释、剖面地震相监控的相分析技术,可以实现"平剖融合"的地震微相分析;相控岩性平均速度充填建模和有色反演的有机结合,可以实现低勘探区(少井或无井地区)生屑滩相储层预测;沉积结构和沉积微相控制下的速度-孔隙度转换,可以有效解决低勘探区生屑滩相储层物性预测难题。实例表明,该方法流程和关键技术对于生屑滩相储层物性预测行之有效。
[Abstract]:In order to solve the problem that the heterogeneity of bioclastic beach reservoir is strong, and it is difficult for conventional geophysical techniques and methods to accurately predict its reservoir and physical properties, a set of seismic microphase analysis and phase-controlled reservoir inversion are studied and formed. The method flow and key technology of lithoclastic beach reservoir and physical properties prediction are integrated with phase-controlled porosity prediction. The results show that the seismic microphase analysis of "flat profile fusion" can be realized by the interpretation of plane sedimentary facies based on waveform clustering and the phase analysis technology of profile seismic phase monitoring. The organic combination of phased lithologic average velocity filling modeling and colored inversion can realize the prediction of cuttings beach reservoir in low exploration area (less well or no well area). The conversion of velocity to porosity under the control of sedimentary structure and sedimentary microfacies can effectively solve the problem of predicting the physical properties of bioclastic beach reservoir in low exploration area. The example shows that the method flow and key technology are effective for predicting the physical properties of bioclastic beach reservoir.
