摘要:
桩海潜山经历了多期构造运动,地层非均质性强,导致地震反射速度变化大、地震信号弱。内幕断裂体系复杂,发育正、逆及走滑等类型断层,内幕断裂的识别与描述既是潜山勘探突破方向亦是难点所在。在开展精细地层对比落实断点,井震结合落实井钻遇断层性质的基础上,利用最大似然法计算每口井钻遇断层性质的判别函数,同时对其它未钻探区域的地震道提取同样的地震属性参数,通过已钻遇井的判别函数来识别断裂有利相似区,从而实现利用已知井对未知地震道进行预测的目的。结果表明,该技术可以较精确的落实潜山内幕断裂,扩大桩海潜山的勘探空间,为后续井位的部署提供可靠依据。
Abstract:
The buried hills of the Zhuanghai area has experienced multi-period tectonic movements.So the stratigraphic heterogeneity is strong, resulting in a great variation of seismic reflection velocity and weak seismic signal. The internal fault systems are complex,including normal and reverse as well as strike-slipped type faults in the Zhuanghai area.So the recognition and description of internal faults are both a breakthrough direction and a difficulty in buried hills exploration.Based on the fine stratigraphic correlation and well-earthquake with seismic attributes to distinguish the breakpoints,the maximum likelihood method was used to calculate the discriminant function of each well-drilled fault properties.Meanwhile,to recognize the favorable similar area of the fracture,the same seismic attribute parameters of the other undrilled area were extracted by the use of the discriminant function of the drilled well. Thus, it is realized to predict the unknown seismic trace by using the known well.The results show that the method can predict faults accurately,expand the exploration spaces of buried hills in the Zhuanghai area,and provide a reliable basis for the subsequent well deployment.
