摘要： 以新疆准噶尔盆地西部25 口井600 块岩样资料为依据, 模拟地下状态, 对岩石在饱含油、饱含水条件下进行了纵、横波速度测定。找出了影响速度的因素及其在不同因素下纵、横波速变化的规律性, 并将速度资料及由此导出的信息用于测井曲线校验、油气的预测及油气水检测。

Abstract: Based on 600 samples data from 25 wells in western Junggar basin, this paper simulated their subsurface state, measured P- and S-wave velocity of rock saturated with water and oil, found the factors affected velocities and the regularity of P- and S-wave change.The log curve calibration, oil/gas prediction and oil-gas-water detection were made by using these velocity data and induced information, a new method was offered for oil exploration.
