【摘要】：三元复合驱集输系统随着见剂浓度的升高,生产运行过程中主要存在三方面问题:一是集输工艺淤积结垢问题突出;二是部分环节不能清垢问题;三是部分工艺清垢工作程序复杂。为缓解三元系统淤积结垢程度,提高三元集输系统清垢工作覆盖率及工作效率,达到安全、环保、高效运行,因此有必要开展“三元复合驱集输系统清垢配套技术研究”。本项目以第四采油厂杏六区东部三元复合驱集输系统为研究对象,通过科研、跟踪2008年—2014年现场运行情况及效果,完成了以下研究内容。(1)开展了三元转油站大罐沉降工艺适应性研究,改善了掺水水质,缓解了系统淤积结垢问题,确定了在以后产能建设中三元集输系统以转油放水站工艺代替原转油站的工艺模式。(2)研制出了泵前快开式过滤器、站内除垢工艺接头、站间管道清淤除垢快速连接装置、滑动伸缩式测温管、计量间除垢工艺阀组、油井组合式井口等6项新技术,研究成果覆盖三元整个集输系统,保证了系统平稳、高效运行。实现了三元复合驱集输系统计量间及单井管线清垢无死角,从而延长阀组及管线使用寿命;实现三元淤积物处理达到污泥排放含油≤2%的排放标准。
[Abstract]:There are three main problems in the process of production and operation of ASP flooding system with the increase of the concentration of binder: first, the problem of deposition and scaling in gathering and transportation process is prominent; Third, some of the process cleaning procedures are complex. In order to alleviate the degree of deposition and scaling in the ternary system, to improve the coverage and efficiency of the scale removal work of the ternary gathering and transportation system, to achieve safety, environmental protection, and efficient operation, Therefore, it is necessary to carry out "study on scaling and supporting technology of ASP gathering and transportation system". This project takes the eastern ASP flooding system of No. 4th oil production plant as the research object, through scientific research, tracking the field operation and effect from 2008 to 2014. The following research contents are completed. (1) A study on the adaptability of the large tank settlement process of the three Yuan transfer Station has been carried out, which has improved the water quality of the mixed water and alleviated the problem of silting and scaling in the system. In the future production capacity construction, the ternary gathering and transportation system replaced the original oil transfer station with the oil transfer station technology. The technology model. 2) developed the fast open filter in front of the pump, the scale removal process joint in the station, and the quick connection device for removing silt and removing scale in the pipeline between the stations. Six new technologies, such as sliding telescopic temperature measuring pipe, scale removal process valve group between metering room and combined wellhead of oil well, are used to cover the whole three-way gathering and transportation system, which ensures the system to be stable. In order to prolong the service life of valve group and pipeline, the ternary silt treatment can meet the discharge standard of sludge discharge with oil content 鈮，
