摘要: 流花11-1油藏生物礁灰岩的储层储集空间以孔隙型和溶洞-微裂缝-孔隙型为主,孔隙结构呈双峰分布.采用岩心渗透率对测井和地震渗透率逐级刻度的方法,确定了5m×5m三维地震分布范围的孔隙渗透率.然后利用反映地下储层的动态测试渗透率刻度地震孔隙渗透率,得到非单重介质渗透率,从而得到了既具有地震资料广泛分布特点又具有准确体现地下储层流体渗流特征的非单重介质渗透率地质模型.生产动态分析和油藏数值模拟证实非单重介质渗透率比孔隙渗透率能够更好地反映地下储层流体的渗流特征,在油田开发和剩余油分布研究中应用效果更好.该方法在类似油藏中值得借鉴和推广.

Abstract: In Liuhua 11-1 oil reservoir,most pore spaces of ecologic reef reservoir are in the pore morphology and cavern-micro fracture-pore style,and the pore configuration was characterized with bimodal distribution.The step scale method was used to calibrate logging and seismic permeability using core permeability and determine the pore permeability from 3-D seismic data of an area of 5 meter multiplied by 5 meter. Multi-porosity system permeability in 3-D seismic scale was got using dynamic checkout permeability to calibrate seismic pore-permeability. A geologic model for multi-porosity system permeability characterized by 3-D seismic scale and fluid percolation was established.The oilfield production and remaining oil research proved that the permeability of multi-porosity system could describe the flow property of fluid in reservoir better than the pore permeability.Good application results of productive dynamic analysis and reservoir numerical simulation can be obtained.This method can be used in similar oil reservoir.
