摘　　要：MY-Ⅲ具有破乳、降粘和一定的溶蜡作用,是一种能解除油井近井地带堵塞的复合型油层处理剂。本文介绍了MY-Ⅲ油层处理剂的研制情况和现场试验结果,提出了MY-Ⅲ的现场应用工艺。A new type of blockage-relieving agent,MY-Ⅲ,for production wells in Laojunmiao Oil Field is developed,being nonionic surfactant/anionic surfactant/auxiliary alcohol/ inorganic salt aqueous systems.It can reduce oil/water interracial tension significantly and be capable of demulsification,viscosity reduction,and paraffin dissolving. Through sieving tests AE1910/Penetrant T/n-butanol/sodium hexametaphosphate systems are selected and a series of work formulations are suggested on the basis of laboratory tests.Two formulations(of low and high total concentration)have been used in blockage- relieving operations in 62 production wells and the results obtained are satisfactory.The technological aspect of operations on agent MY-Ⅲ is described in detail.
