摘要
AVO处理分析是一种利用地震反射振幅信息进行油气检的测技术。首先依据钻井资料进行AVO正演模拟和分析;在此基础上,采用优化的处理流程和保幅处理技术对野外地震数据进行AVO处理;依据AVO处理成果资料与各种地震地质资料综合分析后,提出油气勘探的有利区带。该技术多次为焉耆盆地油藏描述提供了可靠的基础资料,并经钻井证实,其成果资料为降低盆地探井风险提供了有价值的决策依据。
AVO processing is to detect hydrocarbon by using amplitude information of seismic reflection. First, AVO forward modeling and analysis were carried out by using drilling data, then AVO processing of field seismic data were performed with optimal processing flow chart and preserved amplitude processing technology, and finally favorable zones for exploration were delineated based on AVO processing results and comprehensive analysis of various seismic and geologic data. This technology has provided reliable basic data for reservoir characterization in Yanqi basin. Actual drilling operation verified that AVO processing results formed a valuable decision basis for lowering drilling risk in this basin.
