渤海稠油脱水工艺试验研究

本文简要介绍了渤海稠油脱水工艺的基础试验研究,指出对于埕北原油,在电潜泵生产条件下稳定的W/O乳状液含水最高(40％左右);海水配制的W/O乳状液稳定性较差,脱水较容易;磁处理后脱水效果提高20％以上;污水回掺工艺可改善热化学沉降脱水效果;类似埕北稠油的热化学沉降脱水工艺,一段比两段脱水流程优越;埕北油田应选用比现用的AE8031和SP169更好的破乳剂。

Dehydration Process Experiment Research of Bohai Heavy Viscous Crude

The article simply introduces some basic experiments in dehydration process for Bohai heavy viscous crude, and points out that the moisture content of static W/O emulsion for Chengbei crude is the highest (about 40%) in the condition of using the submersible electric pump; the stability of the W/O emulsion from sea water is not strong and the dehydration is easier;the dehydration rate increases by 20% after magnetiza-tion; sewage returned process can improve the effect of thermochemical settling dehydration ;the thermo-chemical settling dehydration process similar to Chengbei viscous crude is better than two stages;the better demulsifier shoud be selected in Chengbei Oilfiled.
