井震结合方法在断层精细解释中的应用——以喇嘛甸油田北北一区块为例
|
摘要
断层精细解释在油田开采后期尤为重要。目前识别断层的方法很多,本次利用本征值相干体技术识别较大断层,确定断层走向,之后主要讨论井震结合方法在喇嘛甸油田北北一区块断层精细解释中的应用。断层的存在在井上表现为断裂带两侧地层存在落差。在地震时间剖面上往往表现为反射波同相轴错断,标准反射同相轴发生分叉、合并、扭曲、强相位转换等现象。通过井震结合对比分析,对研究区原1#4、#断层进行重新组合,对6#断层的延伸长度重新厘定,最终完善了局部构造。为剩余油的挖潜、油田注采提供构造指导。
Fine explanation of fault is particular important for post-oil minning.At present,a lot of ways can be used to identify faults,this using technology of eigenvalue coherence to identify large faults,determine fault strike,mainly discuss the application of the combination of method well seismic in the fine explanation of fault in North-North One Lamadian Oil Field.In the well,the presence of faults will show stratigraphic sepration at the both sides of the fault zone.In seismic time section,the faults are often shown as phase axis cutting of the reflected wave,the standard reflection phase axis show bifurcate,merge,distortion,strong phase shift,etc.Through the comparative analysis of the combination of method well seismic,the original fault of 1#,4# are recombined,the length of the fault of 6# is reclassified.Eventually improve the local structure,it will provide tectonic guide for tapping the remaining oil and injection-production.
