摘要

通过对西北某油田井筒内原油组成、含蜡量和脱石蜡点的分析,研制出化学脱石蜡剂QLJ-1。采用正交试验确定配方为:混合有机溶剂(70%芳烃、烷烃体积比为 2:2:1)+混合表面活性剂(7%吐温-80、AEO-9、脂肪酸盐质量比为 1:2:1)+23%纯水。动力学和乳液稳定性研究结果表明,QLJ-1 的饱和溶蜡量为 1.62 g,溶蜡速率为 0.0263 g/min,溶蜡平衡时间约为 1 h,乳液稳定时间为 6 d。本文的研究成果可为西北某油田改进化学除蜡工艺提供技术支持。

Development and Performance Evaluation of Paraffin and Aromatic Hydrocarbon Synergistic Lotion Wax Remover

The chemical paraffin removal agent QLJ-1 was developed by analyzing the composition of crude oil, the wax content and the point of paraffin removal in the wellbore of an oilfield in northwest China. The orthogonal test was used to determine the formula as follows: mixed organic solvent (70% aromatics, alkane volume ratio of 2:2:1) + mixed surfactant (7% Tween-80, AEO-9, fatty acid salt mass ratio of 1:2:1) +23% pure water. The results of kinetics and emulsion stability study show that the saturated wax dissolution amount of QLJ-1 is 1.62 g, the wax dissolution rate is 0.0263 g/min, the wax dissolution equilibrium time is about 1h, and the emulsion stability time is 6 d. The wax dissolving effect of QLJ-1 is better than that of the current paraffin remover. The research results of this paper can provide technical support for improving the chemical paraffin removal process in an oilfield in Northwest China.
