摘　　要：简述了四川省珙县筠连矿区大雪山矿段(东段)煤矿普查工程的概况、项目由来及定向孔设计。重点介绍了钻探施工定向钻进的技术路线、方案及技术要点,有线随钻定向钻进效果、经济效益、取得的成果。主要工作包括:配套XY-2000型立轴式液压钻机、BW-320/10型泥浆泵、HC绳索取心钻杆;采用ADST测斜仪,通缆水笼头有线随钻测量定向,螺杆马达孔底动力钻具造斜施工受控定向钻孔。在2个1000 m以深的钻孔中,共造斜29回次,总进尺73.78 m。钻孔轨迹基本受控,达到了地质目的。施工中,探索了定向钻进螺杆钻具弯接头的角度选择、适宜绳索钻杆钻进的弯曲强度等问题。This paper briefly describes the general situation of coal mine survey project in Daxueshan mining block（in the east part） of Yunlian mining area in Sichuan,including the project background and the directional hole design;mainly introduces the technical route,program and technical points,as well as the drilling effects,economic benefits and achievements obtained by cabled directional drilling.With XY-2000 spindle type hydraulic drilling machine,BW-320/10 mud pump,HC wire-line coring pipe,ADST inclinometer putting through the cable swivel for measuring while drilling,the controlled directional hole was constructed by whipstocking with screw motor BHA.In 2 ultra-deep holes of more than 1000 m in depth,the total footage was 73.78 m with 29 whipstockings.The drilling trajectory was basically controlled to reach the geological target.In the construction,the selection of the bent joint angle of screw drill tools for directional drilling and the decision of bending strength suitable to wire-line drill pipe were explored.
