摘　　要：目前国内外广泛应用的可循环泡沫钻井液 ,较好地解决低压地层和长段破碎带地层的井漏问题 ,取得了很好的技术经济效益。但由于以往的研究多偏重于室内及理论计算 ,现场测试数据不多 ,对可循环泡沫钻井液的特性及治漏机理存在一定程度上的认识不足。文中主要通过矿 2井的现场试验 ,在取得大量实测数据的基础上 ,通过分析 ,对可循环泡沫钻井液特性有了更进一步的认识。The circulating foam drilling fluid which has been wildly used in China has solved the problem of serious lost circulation in drilling the abnormal low pressure intervals and long section of crushed-zone.It has created good technical and economic benefit .However,the past studies focused on the experiments in lab.and theory calculations and there is lack of field test data.Those result in the lack of knowledge about the characteristics of the circulating foam drilling fluid.This paper enrich the knowledge about the characteristicsof the circulating foam drilling fluid,expecially about the applying conditions of the drilling fluid by analyzing the field test data obtained from spot experiments in well Kuang 2.
