双井微测井技术在表层结构调查中的应用
|
摘要
双井微测井技术是比常规微测井技术和小折射方法更先进的一项新技术。该方法能更准确地为野外地震资料采集选择最佳激发岩性和井深,确保野外地震资料采集质量。利用双井微测井资料可以得到地震工区内表层速度和厚度在横向上和纵向上的变化规律,为地震资料的室内处理提供静校正量。将这项技术应用于大庆油田的地震勘探中,利用数据处理解释和波动力学分析等方法对微测井资料进行了分析研究,确定了最佳激发深度和岩性,并提供了工区的静校正量。
Twin-well microlog is more sophisticated than conventional microlog and shallow refraction. It offers more suitable shooting hole depth and favorable lithology. Twin-well microlog data can be used to infer the variability of velocity and thickness of near surface in vertical and horizontal direction, as well as statics. The method has been used in seismic exploration in Daqing Oilfield in which the twin-well microlog data were analyzed by data processing techniques and wave mechanics analysis to determine optimal shooting hole depth and lithology and provide statics in the survey area.
