| 中文摘要:在贵州某磷矿区钻孔施工中，由于地层水敏性导致钻孔出现掉块、坍塌，局部超径、沉渣增多等，发生钻具扭断、埋钻等事故。采用绳索取心钢球支撑小径锥面钻头定位偏斜技术对事故进行处理，经济有效。 |

| Abstract:Because of the block falling, collapsing, local over sizing and more sediment in water sensitive formation, drilling broken and burying drilling occurred in the boring construction in a phosphate mine in Guizhou. Small diameter cone bit positioning deflection by wire line coring with steel ball supporting was used to solve the problem economically. |
