自1980年以来,经5000余次反复试验,研制出效果好、成本低的 DW8012水基清蜡剂和 PW8105系列防蜡剂。1982年在大庆采油七厂10口抽油机井上,进行清蜡防蜡相结合的现场试验,结果使油井清蜡周期由原来的20～30天,延长至110～280天(油井产量有不同程度的增加),清蜡温度由原来的80～85℃降至60～70℃,从而节省了电能、热能,获得了较好的经济效益。1984年在大庆油田528口抽油机井上推广应用这种清防蜡剂后,效果也很显著。
Since 1980, after more than 5,000 times trial and error, developed a good effect, low cost DW8012 water-based wax and PW8105 series paraffin inhibitor. In 1982 Daqing oil production plant seven pumping wells 10 wells, the paraffin wax combination of field trials, the result of the oil well waxing cycle from the original 20 to 30 days, extended to 110 to 280 days (oil well production is different Degree of increase), waxing temperature from the original 80 ~ 85 ℃ to 60 ~ 70 ℃, thus saving electricity, heat, get better economic benefits. In 1984 in Daqing Oilfield 528 pumping wells to promote the use of this paraffin wax, the effect is also very significant.
