温度对泡沫性能影响的实验研究

泡沫作为一种特殊的钻井流体,其在环空中的泡沫质量、密度、稳定性以及流动状态等都将受到井内温度变化的影响.针对这一问题,通过实验,研究了温度对发泡液起泡能力及泡沫稳定性的影响.实验发现:基液的发泡能力受基液配方和发泡温度影响很大,在一定范围内温度升高可以提高泡沫的稳定性,但温度过高又会对泡沫的稳定性起反作用.

Experimental Research on Foam Effects to Temperature

As a special drilling fluid, the foam will be affected by temperature in quality, density, stability as well as the flow state in the annular space. Aiming at this problem, the paper studied the foaming ability and stability influenced by temperature based on experiment results. It was found that: the foaming ability of the base fluid had been greatly influenced by foaming formulations and temperature, in a certain limit, the stability of the foam will be increased with the temperature rising, but too high temperature will play reaction to the stability of the foam.
