摘要
论述了泡沫的两个基本性质：起泡性和稳定性。对起泡性和提高泡沫稳定性的方法作了评价。通过对发泡剂及稳泡剂的筛选,研制出了低密度泡沫完井液的配方。试验结果表明：此泡沫完井液体系密度可控（0.6～0.75 g/cm3）、稳定时间长,具有很好的储层保护效果。
Tow basic properties of the foam including foamability and stability were discussed. The methods to improve the foamability and the stability were evaluated. Through screening the foaming agents and the stabilizers, a formula of low-density foam completion fluid was developed. The experimental results show that： the density of this foam completion fluid system can be controlled in the range of 0.6 ～ 0.75 g/cm3, the foam completion fluid system has good stability and protective effect to reservoir.
