多分量地震资料处理解释技术研究

The process-interpretation technique of multi-component seismic data

随着油田勘探开发的不断深入,多波多分量地震资料的应用也越来越广泛.本文结合实际资料,对多波多分量地震资料的处理和解释方法进行了探讨和研究,主要针对多波资料的静校正、叠加成像、转换波资料的共转换点的求取方法等技术进行了分析研究,开发了综合利用多波资料进行地震属性和各向异性研究的方法,形成了一套较完善的多分量地震资料的处理、解释技术系列.经过在胜利油田罗家地区的初步应用,表明了预测结果与钻井资料相吻合.

With the deepening of oilfield E＆P, the multi-wave and multi-component seismic data have been found wider and wider applications. According to the real data, the process-interpretation method of multi-wave and multicomponent seismic data is discussed and studied in this paper, mainly aiming at the static correction and stack imaging of multi-wave data, as well as the computing method of common conversion point of converted wave etc. The method of comprehensive applying seismic attributes and anisotropy in multi-wave data is developed, and a series of process and interpretation techniques of multi-component seismic data is formed perfectly. By applying it in Luojia area primarily, it is shown that the predicted result matches the drilling data.
