胡状联合站于2008年8月-2009年5月进行了原油密闭处理工艺系统改造,主要完成了胡状-庆祖集油田(后简称胡庆油田)原油经分离器脱水计量后进入缓冲塔的改造,脱水方式由改造前自然沉降脱水转变为改造后电脱水器脱水处理,对站内电脱水器进行了修复更换使用,停用站内5000m3低含水罐,原油处理工艺采用密闭流程。针对该站原油处理工艺改造前后的不同,老化原油回收处理成为站内的瓶颈问题,结合站内生产实际,通过老化原油性质的研究,对处理工艺不断进行探索,形成了目前较为成熟的老化原油回掺处理工艺。
Hu Lian Joint Station in August 2008 - May 2009 carried out a closed system of crude oil processing technology reform, mainly completed Hu - Qingzuji Oilfield (hereinafter referred to as Huqing Oilfield) by the dewatering of crude oil after entering the buffer tower , The dehydration mode is changed from natural sedimentation and dehydration before the transformation to dehydration treatment after the transformation, and the electromydish dehydrator in the station is repaired and replaced, and the 5000m3 low water tank in the station is deactivated. The crude oil treatment process adopts a closed process. Aiming at the difference of crude oil treatment process before and after modification, the recovery and treatment of aged crude oil becomes the bottleneck in the station. Combined with the actual production in the station, through the study of the nature of aged crude oil, the treatment process is continuously explored to form the mature aging crude oil back mixing Process.
