| 中文摘要:]微泡沫钻井液本身具有防漏、堵漏能力，尤其适用于绳索取心在固体矿产勘探中普遍存在的微裂隙漏失，而且无需专门设备、不影响正常钻进，加之微泡沫钻井液具有润滑性好、携带岩屑能力强、岩心保护好、井壁稳定等特点，更加有利于提高绳索取心钻进效率、减少事故发生。因此将微泡沫技术应用到绳索取心钻进中前景很好，潜力很大。 |

| Abstract:Micro-foamed drilling fluid has the ability to control lost circulation, which is more applicable for wire-line coring drilling in mineral exploration where micro-crack lost happens frequently with the advantages of good lubrication, high capacity of cutting transportation and core protection etc. but without necessity of special equipment. Micro-bubble drilling fluid is conducive to improve the efficiency of wire-line coring drilling and reducing accidents; therefore, this technology has good prospects and great potential for wire-line core drilling. |
