复杂断块油田地震成像关键技术研究
|
摘要
复杂断块油藏是一种常见的陆相沉积油藏,在我国陆上和近海多有分布.涠A油田作为近海复杂断块油气藏,其显著特点是断层复杂、储层非均质性强、储层分布及连通性复杂,致使地震成像不清,给后续的油藏和开发带来极大的困难.针对上述问题,从地震资料成像处理技术和解释性成像处理技术方面展开研究和攻关,在成像方面,提出了叠前成像处理及目标成像处理的理念和思路,并在此基础上,发展了叠前各向异性深度偏移、优势道叠加、面元中心化偏移、叠后分频成像、扩散滤波和方向金字塔滤波等一系列技术和方法,取得了很好的效果.在断层解释中,建立了以下的断层解释方法及解释流程:在扩散滤波数据体上进行相干、倾角、方位角检测,沿着相干方向进行方向金字塔处理,从断层的平面解释出发指导断层的剖面识别,从而提高小断层的识别能力.形成了一套复杂断块油田地震成像关键技术,对油田下一步的开发部署调整具有重要的指导意义,对其它类似油田的生产开发也具有重要的参考作用.
Complex fault block oil reservoir is a common continental sedimentary reservoir,onshore and offshore in China more than a distribution.WZA offshore oil field as a complex block reservoir,its distinguishing feature is the fault complex,reservoir heterogeneity,reservoir distribution and connectivity of complex,resulting in seismic imaging is unclear,to bring up the reservoir and the development of to great difficulties.In response to these problems,from the seismic data imaging technology and processing technology to start an interpretative study and research in imaging,the proposed target pre-stack imaging and image processing concepts and ideas,and on this basis,the development of the stack before the anisotropic depth migration,dominant Road overlay,panel center of migration,stack frequency imaging,diffusion filter,and the direction of a series of pyramid filtering techniques and methods,and achieved very good results.In addition,fault interpretation,create the following and explain the fault interpretation process: the proliferation of the coherent body of data filtering,dip,azimuth detection,coherent direction along the direction of pyramid processing,starting from the fault plane interpretation of guidance the profile to identify,to improve the recognition of small faults.The formation of a complex fault block oil field key seismic imaging technology,the next step in the development and deployment of field adjustment of important guiding significance to the development of other similar oil production also has important reference.
