摘　　要：从发展海上油气混输特殊工艺要求出发,介绍中科院力学所"十五"期间,在油气水分离技术方面开展的研究工作。此工艺用于春晓油田,油中除水,再进行油气混输,防止长距离管输时在高压低温条件下油中产生水化物而阻塞管线。在文献总结、专利调研和国内现场考察的基础上,提出研制集重力、离心、膨胀于一体的复合式分离器,以达到高效快速分离的目的。并对国内外尚未使用过的螺旋管分离装置,开展了油水分离的一些理论及实验研究。Based on the special technique requirements for the oil-gas multi-phase flow transportation in submarine pipeline, some research work on oil-gas-water separation technique is introduced in this paper. It is applied at the Chun-Xiao oilfield, by dewatering from the oil and oil-gas multi-phase transportation, the blockage instances of the pipeline caused by the hydrate generated under the conditions of high pressure and low temperature in the long distance pipe transportation can be prevented. By summarizing the relational references, proceeding the patent retrieval and the domestic on-the-spot investigation, a combined separator based on the principal of gravity, centrifugation and expansion is proposed for the high efficiency and quick separation. Some theoretical and experimental research for the oil-water separation in the helical pipe which is not used yet is developed.
