摘　　要：通过室内试验对油基泡沫钻井液的发泡效果、稳泡效果、流变性能、抗污染能力、储层保护性能进行了评价,并在米气7H井和勒11-1井进行了现场试验。实际应用结果表明,油基泡沫钻井液体系具有良好的防漏能力,实现了近(欠)平衡压力钻井,有效提高了机械钻速,减少了油层浸泡时间,达到了保护储层的目的。该油基泡沫钻井液的应用,为解决吐哈油田强水敏地层的井壁稳定、低压储层的储层保护实现了钻井液技术的新探索,对提高低压气藏开发效果具有重大现实意义。According to the indoor test,oil-based foam drilling fluid foaming effect,the bubble effect,rheological properties,the ability of pollution resistance,reservoir protection performance are evaluated,and the test of Well MQ7 Hand Well LE11-1is carried out.Practical application results show that the oil-based foam drilling fluid system has good leakproof ability,it realizes the close balance(unbalance)pressure drilling,effectively improves the mechanical drilling rate,reduces the oil immersion time,achieves the goal of the reservoir protection.The application of the oil-based foam drilling fluid can solve the problem of high water sensitivity reservoir of borehole wall stability,low pressure reservoir protection improve the effect of low pressure gas reservoir development,it has important practical significance.
