【摘要】 对于复杂断块老油田,应用三维地震资料,采取井震结合的方法,落实老油田对渗流场和剩余油具有控制作用的低级序小断层发育状况,深化曲流河废弃河与点砂坝配置模式以及辫状河心滩坝发育模式研究,精细表征曲流河点坝内部侧积层或辫状河心滩坝落淤层发育规模,为剩余油分布研究和深度开发方案编制奠定了坚实的地质基础,现场应用取得突出效果。更多还原

【Abstract】 For complicated fault block old fields,make sure development status of lower order small faults where old fields have a control action on seepage field and residual oil by applying 3-D seismic data and integrating well data with seismic data,the configuration mode of abandoned channel in meander river with point bar and developmental patterns of batture bar in braided channel were further studied,fine characterization was made for lateral accretion bedding in point bar and the development scale of the off silt layers of batture bar in braided channel,which laid a solid foundation for study of the remaining oil distribution and preparation of deep development program,field practice has achieved good results.更多还原
