2种原油预脱水工艺方案分析与比较

为了使含水原油达到管道外输的要求,要对其进行脱水处理。而在含水原油进入油水分离装置之前,通常要经过预脱水过程。采用破乳剂工艺方案与回掺底水预脱水工艺方案,对辽河油田高一联原油进行预脱水实验。实验结果表明：原油中加入破乳剂的预脱水率不到20％,而回掺底水预脱水实验的预脱水率高达65％以上,最后确定回掺底水预脱水工艺方案为最佳方案。

Uncertainty in predictions of oil spill trajectories in a coastal zone

A method is introduced to determine the uncertainties in the predictions of oil spill trajectories using a classic oil spill model. The method considers the output of the oil spill model as a function of random variables, which are the input parameters, and calculates the standard deviation of the output results which provides a measure of the uncertainty of the model as a result of the uncertainties of the input parameters.In addition to a single trajectory that is calculated by the oil spill model using the mean values of the parameters, a band of trajectories can be defined when various simulations are done taking into account the uncertainties of the input parameters. This band of trajectories defines envelopes of the trajectories that are likely to be followed by the spill given the uncertainties of the input.The method was applied to an oil spill that occurred in 1989 near Sines in the southwestern coast of Portugal. This model represented well the distinction between a wind driven part that remained offshore, and a tide driven part that went ashore. For both parts, the method defined two trajectory envelopes, one calculated exclusively with the wind fields, and the other using wind and tidal currents. In both cases reasonable approximation to the observed results was obtained.The envelope of likely trajectories that is obtained with the uncertainty modelling proved to give a better interpretation of the trajectories that were simulated by the oil spill model.
