摘要
///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. Micro-bubble drilling fluid is conducive to improve the efficiency of wire-line coring drilling and reducing accidents. Therefore, this technology has good prospects for wire-line core drilling.
