摘要
为解决XX51断块中间基原油清蜡降粘的问题。通过大量的单剂及复配实验后,进行以溶蜡速度、降粘率、降凝率、防蜡率为因子的四因素、四水平正交试验、复配筛选。找到了适合XX51断块原油的新型化学药剂。自2012年起在XX51断块的200余口稠油井上应用,油井热洗周期平均延长150天。全年减少热洗1500井次。每次热洗按3000元计,则全年节省费用450万元。
In order to solve the problem of the oil removal of the intermediate base crude oil in the XX51 block. The four factors, four factors, the orthogonal test and the combination of the factors, the factors, the rate of viscosity reduction, the viscosity reduction rate, the rate of paraffin removal, and the wax removal rate, were carried out. A new type of chemical agent suitable for XX51 fault block oil was found. Since 2012, the application of the XX51 block in the 200 wells, the average heat washing cycle of the oil well is extended by 150 days, resulting in reduction of hot wash 1500 times a year. In the end, the annual savings of 4.5 million RMB was achieved accordmg to 0.3 million of each heat wach.
