| 摘 要： | 酸化是解除地层伤害的重要措施之一。通过对酸渣形成机理及其影响因素的研究,优选了聚氧化乙烯、聚氧化丙烯类表面活性剂作抗酸渣剂,研制出了具有抗酸渣性能的酸液体系。室内试验和塔中4油田现场应用结果表明,该体系适应性强,能有效地解除试油层近井地带的污染堵塞。

| Abstract: | Acidizing is an important measure to re-move formation damage. The mechanism of the formation sludge induced by acid is discussed. Two surfactants are selected to resist sludge, such as polyethylene glyco! oxide, polypropylene glycol oxide. Tests at 3 wells of Tarim show that this acid sys-tem has good compatibility, removes formation plug near wellbore effectively. |
