采用大庆油田采油四厂杏二中原油和污水,在室内配制原油乳状液,研究了不同结构破乳剂(SP169、BP169-21、AE9901、AR36、AP221、TA1031)及其浓度对不同矿化度原油乳状液的适用性.结果表明:AR36脱水速度最快、水色清、油水界面清晰,最大脱水率为88%,适用于大庆杏二中原油乳状液的脱水;AE9901的脱水率为72%,SP169为70%,TA1031为64%,BP169-21为58%,AP221为54%.AR36存在最佳使用浓度(200mg/L);SP169、AP221脱水率随浓度的增加而增大.破乳剂浓度增加,可降低油水界面黏度,减弱界面膜强度,从而提高脱水效率.AR36脱水率随矿化度增加而增大,适用于高矿化度乳状液脱水;BP169-21脱水率随矿化度增加而减小,不适合高矿化度乳状液脱水.其它4种破乳剂的脱水效率与矿化度无对应关系.

Using Xing'erzhong crude oil of Daqing Oilfield to prepare crude oil emulsion, applicability of demulsifiers with different structures (SP169, BP169 - 21, AE9901, AR36, AP221, & TA1031) and its concentration to different Salinity emulsion were discussed. Results show that effect of AR36 is the best, whose dehydrating velocity is fastest, dehydrated water is clean, oil - water interface is clear and dehydrating rate is 88% , the highest. Dehydrating rate of AE9901 is 72%, SP169 is 70%,TA1031 is 64%, BP169-21 is 58%, and AP221 is 54%. The optimal concentration of AR36 is 200mg/L; The dehydrating rate of SP169 and AP221 increase with concentration elevating. The increase of demulsifiers concentrations reduce interfacial vis cosity of oil-water interface, thus dehydrating rate is elevated. And dehydrating rate of AR36 increase as Salinity is enhanced which adapts to high Salinity emulsion, and dehydrating rate of BP169 -21 decrease as Salinity enhances which does not adapt to high Salinity emulsion. Dehydrating rate of the other four demulsifiers is not correspondent to salinity.
