摘要

摘要: 塔河油田油藏原油高含沥青质,随着油井生产,油藏、井筒压力、温度场的变化,井筒堵塞现象时有发生.采用X射线荧光光谱、组分分析、溶剂萃取等方法分析了堵塞物成分.结果表明,堵塞物90%以上是有机物,有机物中沥青质含量大于38%.针对堵塞物主要组分,研制了新型沥青解堵剂,对其性能进行了评价.60 ℃时溶解速率最高可达到2.956 mg/(mL·min),胶体不稳定指数大于0.9的原油中加入质量分数1%新型沥青解堵剂,可有效抑制沥青质沉积.

Abstract: Due to the high content of asphaltene in crude oil in the Tahe Oilfield, wellbore plugging was very common as reservoir/wellbore pressure and temperature field changed in oil production process. With X-ray fluorescence spectrometry, component analysis and solvent extraction method, the plugging composition was analyzed, among which over 90% was organic matter. Asphaltene accounted for over 38% in the organic matter. A new asphalt plugging removal agent was innovated and evaluated. The highest dissolution rate at 60 ℃ could reach 2.956 mg/(mL·min). For the crude oil with colloid unstable index bigger than 0.9, asphaltene deposition could be inhibited by adding the new asphalt plugging removal agent with mass concentration of 1%.
