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.
