【摘要】 为了更好解决开发区块断层展布问题,在精细地震解释中引入了相干体技术。通过相干体初步分析断裂交切关系,然后在面与体上进行手工解释闭合,建立断裂空间格架。介绍了本征值相干体技术在喇南中东一区的应用,利用沿层相干体分析相邻近地震道的相干性,进而辅助断裂解释。新认识的断层主要在走向、延伸长度、组合、分解和核销5个方面发生变化。通过实际应用可以得出,相干体技术是一种更有效识别断层解释的方法,可以提高构造解释精度,这对日后油田注采开发具有一定的指导意义。更多还原

【Abstract】 The coherence cube technique is applied to fine seismic interpretation in order to resolve the problems of distribution pattern of faults in development blocks.With the coherency cube,preliminary analyzing on the relationships of fault intersected with each other,then fault closure is achieved by interpreting by hand on the surface and body and fault framework is build.It mainly elaborates that the application of the eigen value coherence cube technique carried out in No.1 block of middle east of Lanan Daqing area,with the coherence cube along horizon,to analysis coherent properties of adjacent seismic trace aiming at the fault interpretation and five changes have been summarized among newly recognized faults,such as strike,trace lengths,combinations,segmentations and cancellations after verification of faults.By application of the coherence cube technique to field data,it can be seen that the coherence cube technique is a kind of method of more effectively identification fault,and the tectonic interpretation precision is greatly improved,so as to have the direction significance for injection-production development of oil field.更多还原
