原油流动改进剂应用于防蜡的实验

 某油田产高含蜡原油,在采出及集输过程中造成严重蜡沉积,影响油田的正常生产.利用该油田原油样品,进行新型原油流动改进剂AT-2 的防蜡黏壁及协同破乳剂分水实验.结果表明,AT-2 在采出液样品含水10%~50%时,具有较好的防蜡黏壁效果,在含水40%时黏壁量减少率达到最大值75.36%;当采出液中AT-2 浓度≤100 mg/L 时,原油后续脱水不受影响.实验表明AT-2 可用来解决该油田的蜡沉积问题.

Anti-wax application of crude oil flow improver

The AT-2, a new crude oil flow improver, has been developed targeting the wax deposition problem in an oilfield. Antiwax and water separation experiments were carried out. The result showed that AT-2 had a satisfactory anti-wax effect on the produced liquid sample with watercut of 10%~50%. When the watercut was 40%, the maximum wax reduction rate was achieved, reaching 75.36%; meanwhile, the water separation was not affected when the concentration of AT-2 was lower than 100 mg/L. Considering the watercut of the wells having the wax problem is lower than 50%, the application of AT-2 would solve the wax deposition problem.
