摘　　要：本文主要针对玉门油田严重存在的油层堵塞问题,采用非离子表面活性剂AE1910、阴离子表面活性剂ABS、助剂乙醇和电解质氯化钾复配的方法,研制成MY-1油层解堵剂。该堵剂能解除水堵、乳化堵塞与高界面张力堵塞。采用MY-1油层解堵剂在玉门油田进行了两年的现场试验,取得了较好的解堵效果。This well washing fluid, My-1, is developed for the purpose of relieving blockage in producing reservoir and is composed of a nonionic surfactant, AE1910, an anionic surfactant, ABS, an alcohol, ethanol, and an electrolyte, KCl. It is useful in the cases of reservoir blockage in oil wells caused by water and emulsion sealing and by high interracial tensions. The mechanisms of blockage relieving by MY-1 are discussed. Two-year field tests performed in Yumen Oil Fields with this well washing fluid have given good results in stimulation and recovery of oil production.
