摘　　要：随着气井压力逐年降低,气层抗污染的能力也在下降。为了减少压井液对气层造成的伤害,开发了泡沫压井液,密度在0.60～0.99g/cm3可调,现场配制工艺简便易行,在中原油田天然气产销厂10多口井现场应用,结果表明:该保护液既能满足现场作业施工压井要求,又能有效保护产层。As the pressure of the gas well reduces year by year, the ability of resisting pollution of gas bearing formation is dropping progressively too. For reduce the damage of gas reservoir that caused by well killing liquid,the spume well killing liquid is researched and developed. The liquid density is adjustable between 0.60~0.99 g/cm 3 , and compound the craft simple and easy to do at the scene. Practical application of More than ten Wells on the spot in Zhongyuan Oilfield Natural Gas Production & Sales Factory test indicate, the spume liquid, can meet well killing request in the site operation, and can protect producing formation.
