摘　　要：为提高油田的采油量,研究了一种C_(1)~C_(4)的低碳混合有机酸解堵剂。该解堵剂主要以有机羧酸(甲酸、乙酸、丙烯酸等)、有机磺酸(甲磺酸、氨基磺酸等)、螯合剂、缓蚀剂的组成。通过实验测定了该解堵剂对原油蜡晶和有机垢的溶解能力及是否存在乳化现象等,发现其溶解能力较强且无乳化现象。还对该有机酸解堵剂的表面张力、缓速性能、腐蚀性能及解堵效果进行了实验,发现C_(1)~C_(4)混合有机酸解堵剂具有良好的缓速作用和解堵效果,可以有效地提高原油的利用率。In order to increase oil production in oil fields,a C_(1)~C_(4) low-carbon mixed organic acid deblocking agent was studied.The deblocking agent is mainly composed of organic carboxylic acid(formic acid,acetic acid,acrylic acid,etc.),organic sulfonic acid(methanesulfonic acid,sulfamic acid,etc.),chelating agent,corrosion inhibitor.The dissolving ability of the plugging agent to crude oil wax crystals and organic scale was determined as well as whether there was emulsification phenomenon through experiments,and it was found that the dissolving ability was strong and there was no emulsification phenomenon.Experiments were also conducted on the surface tension,retardation performance,corrosion performance and anti-plugging effect of the organic acid anti-plugging agent.It was found that C_(1)~C_(4) mixed organic acid plugging agent had good retarding effect,strong corrosion performance,and good plugging effect,which effectively improved the utilization rate of crude oil.
