摘　　要：随着油气勘探开发的不断深入及相关学科的发展,复杂地质构造成像与地震岩性成像已成为急需解决的课题.针对中原复杂断块区地震资料的特点,对速度场的建立、叠前偏移中关键参数的选取以及偏移方法展开了深入细致的研究.通过叠前偏移技术在中原油田的应用,结果表明了该技术的有效性.With further exploration and development of oil ＆ gas and the development of relevant subject, Imaging in complex geological structure and seismic lithology has become urgent problem to be solved. Aiming at the characteristics of seismic data from complex fault blocks in Zhongyuan oilfield, the selection of key parameters in pre-stack migration and migration approaches were meticulously studied. With the application of pre-stack migration technique in Zhongyuan oilfield, final results prove the effectiveness of this technique.
