摘要
多分量地震资料解释主要包括纵波和转换横波资料的层位对比标定、纵波和横波地震属性参数计算、储层解释及油气预测等。其中的多分量地震层位对比是岩性解释和油气预测的关键技术环节。根据垦71地区多分量地震资料和纵横波测井资料,分析了转换波剖面的极性,研究了深度域法、剖面压缩法层位对比标定的方法步骤,并在此基础上进行了纵横波属性分析。实际资料的层位对比效果明显,属性分析取得初步成果。
Multiple-component seismic interpretation mainly includes horizon calibration, attribute computation of compressional wave and transerve wave, reservoir interpretation and hydrocarbonpredictionetc In which, horizon calibration is the key step of lithology interpretation and hydrocarbon prediction. The polarity of converted wave profile is analyzed and attribute analysis is based on depth domain and horizon calibration by seismic data of Ken 71. Good effects in horizon correlation with real data are achieved and the preliminary results of attributes analysis were obtained.
