摘要
在实验室中测定了流速0～34m·s－1，风速0～13m·s－1、正弦波高0～0．13m范围内，流、风、波单独存在及共存时，胜利油田原油在水面上的漂移速度，建立了包括流速和风速矢量及波高三个参数的胜利油田原油漂移速度的经验公式。
The drifting speeds of crude oil from Shengli oil field were measured precisely under different conditions of current, wind and wave in laboratory. The coefficients of wind-induced surface current increased linearly with the increase of the velocity of wind. The wave increased the drifting velocity with the existence of wind. When the directions of wind and current were the same, the oil drifting velocities were lower than the sum of the two individual drifting velocities caused by wind and current. When the directions of wind and current were opposite, the oil drifting speeds were greater than the vector sum of the two individual drifting speeds caused by wind and current. When the velocity of wind was about 50 times as great as the velocity of current, the direction of oil drifting changed. Taking account of the vectors of current and wind as well as wave, empiric formulae for the drifting speeds were developed respectively (standard deviations 0. 011 m·s-1).
