地震反演技术在辽河兴隆台地区沙三段储层预测中的应用
|
摘要
地震反演是储层预测三大技术系列的核心,其充分利用地震资料在横向分辨率、测井资料在纵向分辨率上的优势,对储层的空间分布特征进行合理的预测。在对辽河兴隆台地区沙三段地层特征、储层难点分析的基础上,通过地震资料品质的研究与正演分析、测井曲线标准化处理、子波提取与精细合成记录标定等前期处理工作,优选反演参数,并应用约束稀疏脉冲反演技术对沙三段进行了储层预测,精细地刻画了储层的空间展布特征,并落实和优选了2个有利圈闭,部署探井2口,为该区的井位部署及储量上报提供了地质依据。
Seismic inversion is one of the three core techniques in reservoir prediction.Fully using the advantages of the horizontal resolution of seismic data and the vertical resolution of logging data,it can make reasonable prediction of the spatial distribution pattern of reservoirs.Based on the analysis of stratigraphic characteristics of Es3at the Xinglongtai of Liaohe and the challenges been faced with in reservoirs description,we made reservoir prediction through the quality research and forward analysis of seismic data,the standardization of logging curves,wavelet extraction,fine synthetic seismogram calibration and other pre-processing work,optimization of inversion parameters and the application of constrained sparse spike inversion.The reservoir spatial distribution patterns are finely described. The prediction resulted in the selection of the two prospective traps and two exploration wells.The fine description of reservoirs lays a solid geological foundation for well placement and reserve reporting.
