油气水砂多相分离的新方法

, 2008
介质分离器的发展,无论在陆上还是海上油田都受到密切关注.近期研究除快速、高效分离技术外,又向综合多用方向发展.本研究提出一种集油气水砂分离于一体的新的复合分离器,用离心、膨胀原理的复合旋流器先进行气液或气液固分离,然后用梯型管和螺旋管进行油水精细分离,并把上述功能集中在一个分离器中实现.这一方法使油田上采用了多个分离器的工艺流程,减少为单个分离器装置,这样大大减轻重量,缩小体积.尤其对海上油田,发展深海油气采收具有更重要的意义.本分离方法目前已完成实验室原理实验、华北油田现场实验,正在进行新型样机设计 ...

非真空隔热油管研究进展

, 2013
世界上原油储藏中稠油、特稠油和沥青油砂占到储量70%，稠油粘度极高，常温下往往凝结成固态，其开采和炼制技术难度和成本都很高，因而目前国际上普遍没有开采稠油油藏，特别是开采成本和难度最大的海上油田稠油油藏。我国由于原油资源不丰富，出于能源安全的考虑而大量开采稠油。因此，国际上可供借鉴的海上稠油开采经验几乎是空白 ...

Performance test of pipe separation technology in Boxi oil gas treatment plant

, 2012
油气水的分离是石油工业中一个重要的工艺流程,传统的分离罐体积大,质量大,造价昂贵。随着海上油田的逐步开发,降低成本成为石油生产关注的焦点。介绍了一种管道式油气分离新工艺及其试验结果。新型管道分离技术将油气水在管道中一边流动一边分离,达到油气水多相分离的目的。同传统的油气分离设备相比,具有占地面积小,分离效率高的特点。在渤西油气处理厂进行的工业现场试验表明,在试验参数范围内 ...
