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。
The two basic properties of foams are discussed: foaming and stability. The method of improving foamability and foam stability was evaluated. Through the foaming agent and foam stabilizer screening, developed a low density foam completion fluid formulations. The test results show that the foam completion fluid system has a controlled density (0.6-0.75 g / cm3), long stabilization time and good reservoir protection.
