渤海海域地震振幅影响因素分析
|
摘要
在渤海海域海上钻井少的情况下,油气藏勘探开发对地震资料的依赖程度较高,利用地震振幅进行岩性识别和流体检测取得了丰富的成果,但由于地震振幅的影响因素较多,如果不充分研究和认识这些影响因素,会在利用地震振幅信息进行油气勘探开发时掉入陷阱,造成部分井的落空。为了尽量避免地震振幅引起的陷阱,文章从地震资料采集、处理和地质等方面探讨了影响地震振幅的各种因素,这对提高岩性识别、流体检测及探井成功率具有很好的现实意义。
In Bohai sea area, offshore drilling is less, oil and gas exploration and development is in high level of dependence on seismic data. By using seismic amplitude, abundant achievement has been made on lithology identification and fluid detection. Because of many influence factors of seismic amplitude, if not fully studying and understanding these factors, oil & gas exploration and development may fall into the trap by using seismic amplitude information, causing some well lost. In order to avoid the traps caused by seismic amplitude, various factors effecting seismic amplitude are discussed from many aspects as seismic data acquisition, processing and geology, which has practical significance on lithology identification, fluid detection and well exploration success rate.
