摘要
FLW水基防蜡剂主要由1~#、2~#活性剂(用量分别为12.5％)、1％降粘剂和10％助溶剂组成。室内实验表明,防蜡剂加量为100×10^(-6)时,静态防蜡率大于60％,降粘率大于30％,动态防蜡率大于70％。现场试验表明,采用连续加药方式,可减少洗井次数,提高油井产油量。
A water soluble wax inhibition agent FLW was composed of surfactant 1 # ( 12.5 % ) , surfactant. 2 (12.5%), thinner(1%) and auxiliary solvents(10%) . Following results were obtained in laboratory: wax inhibiting rate in static state, viscosity decrement and wax inhibiting rate in flow state were more than 60 % , 30 % and 70 % respectively. It was shown in the oilfield experiment that it could decrease the times of washing well and improve the productivity of oil wells.
