Properties such as the foam volume, half-life and fluid rheology of an oil-based drilling fluid were measured to evaluate the fluids foam stability and drilling performance.The results showed that the key factors influencing the performance of the oil-based foam drilling fluid are the base liquid, foaming agents,stabilizers, and surfactants.The foaming agent provides foam stability and is necessary for air/oil surface adsorption, low surface tension and good film viscoelasticity.The oil-based drilling fluid has low-density foam,low fluid loss, a good sealing effect, anti-high temperature capabilities, and good salt and contamination resistance.

采用转子黏度仪初步研究了压裂液增稠剂疏水基改性羟乙基纤维素(HMHEC)基液体系的流变性,及其与HMHEC在基液中的结构间的关系.结果表明:HMHEC水溶液体系为剪切变稀的流体体系;HMHEC基液体系有较强的温度可逆性和剪切恢复性.HMHEC与HEC在不同剪切速率下，其基液的剪切黏度度均随剪切率的增大而减小。HMHEC基液体系具有温度可逆性，并且HMHEC通过可逆过程后，私度会相对大于基础黏度。
