摘　　要：本文主要针对老君庙油田严重存在的油层堵塞问题,在室内试验的基础上,采用磷酸复配体系,研制成 MV-2油层解堵剂。该解堵剂能解除井筒附近地带的钻井泥浆和腐蚀产物等堵塞。室内与现场试验表明,由磷酸复配的 MY-2解堵剂对低渗透的砂岩油层的解堵效果比常规酸好。This well washing fluid,MY-2,is developed for the purpose of relieving blockage in producing reservoirs and is composed of phosphoric acid,potassium dihydrogen phosphate,a non-ionic surfactant,OP-10,a clay stabilizer,Al-OH,and a corrosion inhibitor.It is useful in the cases of reservoir blockage in oil wells caused by invaded drilling muds and precipitated corrosion and scaling products.The mechanisms of blockage relieving by MY-2 are discussed.Two-year field tests performed in Yumen Oil Field with this well washing fluid have given good results in stimulation of oil production and enhancement of oil recovery.
