随着新疆油田克拉美丽气田的不断开发,高压高产气井的储层保护越来越受到重视.为了降低固相物质及入井液滤失对气藏的伤害,研究开发了无固相气井储层保护液.该储层保护液具有体系无固相、密度调节范围大、低滤失、低粘度、低伤害、性能稳定等特点,密度在1.0 g/cm3～2.30 g/cm3.滴西17高压气井大修套管补贴作业,在打开气层情况下选用密度1.50 g/cm3的无固相气井储层保护液作为修井液,在无固相气井储层保护液中套管补贴2段射孔段,修井作业15天,无固相储层保护液体系均一、性能稳定,保证了修井作业顺利完成,取得良好效果.

With the development of Kelamayi gas field of Xinjiang oil field, the reservoir protection to high temper-ature high pressure gas well is more important then ever. In order to reducing the injure of solid phase and working fluid to gas reservoir, non-solid phase gas well reservoir protec-ting fluid system was studied. It is non-solid phase, densi-ty range is 1.0g/cm3-2.30g/cm3 , short fluid loss, low vis-cosity, low injure and good fluid stability. Being a high pres-sure gas well, casing patch on DX17 is proceeded with gas zone opened. Non-solid phase gas well reservoir protecting fluid system is chosen as workover fluid, its density is 1.50 g/cm3, two perforated interval is casing patched inside non -solid phase gas well reservoir protecting fluid system.During 15 days well workovering, non-solid phase gas well reservoir protecting fluid system is stable and uniform, well workover is fair done, and the effect is excellent.
