STUDY AND PRACTICE OF THE OIL DRIFT AND DIFFUSION ON THE SEA SURFACE IN THE OFFSHORE
Abstract：According to the test results of the drift and diffusion of theoil conducted on the ocean,this paper analyses the drift and diffusion process of the oils into the ocean and consider:(1)the drift speed and direction of surface oils are decided by the speed and directionof the wind and surface current:the oil drift speed and direction accord basically with U0=UC=ζWand D=Ccurrent+r;(2)the diffusion form of surface oils has relationto the drift speed of oil,theat is the faster the drivft the speed of oils is,the oils diffusion speed and tiime can by expressed with Udiffusion=at-b,that is the faster the drift speed of oils is,the longer and narrower the form of oils,ad conversely,the wider adn shorter;(3)the results of two practical examples test during shipwreck oil spill are close to the study result:(4)satisfactory forecast of oil spill drift was obtaned by application of the above to oil pipeline broken in Hui zhou 26-1 offshore oil field in 1996
