- 摘要:
- 针对辽河油田稠油具有黏度大，胶质、沥青质含量高，密度高，油气比低及黏—温敏感性强等特点，辽河油田在多年的开发建设过程中逐渐形成了独具特色的地面集输、处理及配套技术。文章介绍了单管加热集输、双管掺水集输等辽河油田稠油集输典型工艺流程；热化学沉降+电化学的密闭脱水工艺、两段热化学沉降脱水工艺等稠油脱水关键技术；稠油污水深度处理工艺和SAGD注气系统关键技术。为了适应稠油开发方式的转变，探讨了今后稠油集输、处理工艺的发展方向和有待解决的问题。
Heavy oil produced from Liaohe Oilfield has the characteristics of high viscosity and density,low oil/gas ratio, abundant colloid and asphaltene as well as high sensitivity of viscosity emperature. Faced with the problems, Liaohe Oilfield has step by step built up a particular technology of surface gathering and supporting system through many year' s exploitation and construction. In this article, the following techniques developed by Liaohe Oilfield are introduced: the typical heavy oil gathering progress flows such as single pipeline heating gathering and double-pipeline water-mixing gathering, the key heavy oil processes such as hermetic dehydration with thermochemistry sedimentation+electrochemistry, and the dehydration with twostage thermochemistry sedimentation, the deep processing of heavy oil produced water, and the key technique of SAGD gas injection system. In order to adapt for the change in heavy oil exploitation ways, the development trends of heavy oil gathering and treatment and the relevant problems to be solved in the future are discussed.2013,4(4): 68-72 收稿日期：2012-10-9DOI：10.3969/j.issn.1001-2206.2013.04.021作者简介：周立峰(1979-),男,辽宁抚顺人，工程师，2005年毕业于辽宁石油化工大学,硕士.现从事油气田地面工程设计科研工作。参考文献：
