【摘要】 研究区长期以来受资料和技术的限制,对断裂构造的认识存在一定的局限性,特别是低序级断层的识别受到限制,影响油气勘探开发工作。提出利用多体联合精细构造解释技术对营1区块进行构造精细解释,主要利用谱兰化提高分辨率处理技术、断层边缘强化处理技术、相干体处理技术等手段,通过叠后地震数据处理,提高地震资料分辨率和断层识别能力,然后结合相干数据体时间切片精确描述断裂系统,再进行储层精细构造解释。通过采用先确定骨架断层,再描述低序级断层的构造解释程序,研究区共发育断层32条,全部为正断层,总结出铲式、平面式两种断层剖面分布模式;以及平行式、墙角式两种断层平面展布模式。更多还原

【Abstract】 The recognition of the faults and structures in the research area was limited by the data and techniques,especially the recognition of the low-order faults was limited,and oil exploration and development were influenced.It was proposed that synthesizing many techniques were used to accurately interpret the structures in Fault Block Ying 1,the main techniques are the techniques to improve the resolution,strengthen the processing of fault margin,coherent body processing and so on.First,by the processing poststack seismic data,the resolution of the seismic data and recognition capability of fault was raised;the coherent data time slice was used to interpret the fault system accurately,interpret the structures.The process of structural interpretation is to interpret main faults first and describe the low-order fault next,there develop 32 faults in the work area,and all of them are normal fault.Two patterns of faults are established,including scraper pattern and plane pattern;two patterns of fault planes are determibned such as paralleling pattern and corner pattern.更多还原
