秦皇岛QHD32-6海上稠油油田A,B平台于2001年10月18日投产,原油集输处理中使用某外国公司的破乳剂/清水剂组合药剂EC-2029A/EC-6032。2001年12月10~18日以渤海BH-01替换供应中断的EC-2029A,脱水效果大大改善。渤海服务公司专门研制了BH系列破乳剂和BHQ系列清水剂。2002年2~3月试用BH-03/BHQ-04,效果良好,加药量减少而净化油含水合格。2002年4月试用该外国公司的PX-0090/EC-6032,效果良好但流程中某些工艺参数差,且清水剂用量大。2002年5月25日C,D平台投产后换用BH-03/BHQ-04,6月28日换用BH-04/BHQ-04,效果进一步改善,8月10月E,F平台投产后效果仍良好。2002年11月6日短时间试用国内某公司的破乳剂LY-1133失败。2002年12月成功应用新的BH-09/BHQ-06。2003年2月试用该外国公司的PX-0095/EC-6032,引起净化油含水上升。2003年4月试用另一外国公司的破乳剂PT-9179,效果不佳。此后恢复使用BH-09(和HQ-06)。针对QHD32-6油田开发的BH/BHQ系列破乳剂/清水剂性能良好,可使外输原油含水≤0.5%,外排污水含油≤30mg/L。在采出原油含水上升、新平台投产时,应及时评价、更新药剂。表12参2。
Qinhuangdao QHD32-6 offshore heavy oilfields A and B platforms were put into operation on October 18, 2001, and a foreign company’s demulsifier / water-clearing agent combination EC-2029A / EC-6032 was used in crude oil gathering and transportation. December 2001 Dehydration effect was greatly improved by replacing the discontinued EC-2029A with Bohai BH-01 from October 18 to 18. Bohai service company has developed a series of BH series demulsifier and BHQ series of water agent. In February 2002 to March BH-03 / BHQ-04 trial, the effect is good, reducing the amount of drug purification and water purification qualified. April 2002 trial of the foreign company PX-0090 / EC-6032, the effect is good, but the process of some of the process parameters are poor, and a large amount of water agent. May 25, 2002 C, D platform put into use after the switch to BH-03 / BHQ-04, June 28 for BH-04 / BHQ-04, the effect is further improved, August 10 E, F platform put into operation The effect is still good. November 6, 2002 a short trial of a domestic company demulsifier LY-1133 failed. The new BH-09 / BHQ-06 was successfully applied in December 2002. PX-0095 / EC-6032 from this foreign company was piloted in February 2003, causing a rise in the water content of the purified oil. April 2003 trial of another foreign company’s demulsifier PT-9179, ineffective. After that, the BH-09 (and HQ-06) will be restored. The BH / BHQ series demulsifier / water purifying agent developed for QHD32-6 oil field has good performance, which can make the output of crude oil outside the water ≤0.5% and the external discharge of oil ≤30mg / L. In the mining crude oil water rise, the new platform put into operation, it should promptly evaluate and update agents. Table 12 reference 2.
