摘要
本文讨论了气井泡沫排水棒的室内评价方法,对GK-1气井泡沫排水棒的携液、抗油和抗盐等性能进行了研究,并对现场试验结果进行了讨论。研究表明,GK-1气井泡沫排水棒具有携液量大、抗油和抗盐、使用方便、投资少和效益大等特点,便于在气井上大量推广使用。
The foamer GK-1 is composed of a powdered anionic surfactant as foaming agent, a liquid nonionic surfactant as secondary foaming and bonding agent, a powdered dissolution-promoting agent,and an inorganic salt for density adjustment,developed for removing downhole liquor accumulations in gas wells and manufactured and used in moulded bar of weight 500g and densityl.1 g/cm^3.To determine the liquorcarrying capacity of foam,the basic and most important characteristic of the foamer for such purpose, a laboratory measuring device is worked out and established. On this device this characteristic is determined and investigated as influenced by foamer concentration, oil and salt content in foaming solutions as well as by bar density and gas flow rate. This bar-foamer is tolerant to crude oil up to 20%(v/v)and to salt up to 3.5%. GK-1 has passed field tests in many gas wells and has been put into use in Liaohe Oil Fields.
