摘要
介绍了欠平衡泡沫钻井液的优点 ,并从内因和外因两个方面对泡沫钻井液不稳定的原因进行了分析。在此基础上 ,进一步探讨了泡沫钻井液的稳定性和泡沫剂溶液的发泡能力、以及泡沫钻井液的流变性和密度特性等的影响因素和评价方法。
This paper presents many advantages of underbalanced foam drilling fluids.The mechanism of destabilization of drilling foams is also analysed from two aspects of internal and external causes.The stability,foaming ability,rheological property and density of drilling foams with their evaluating techniques are discussed.
