| 摘 要： | 针对深100 m水平钻孔钻孔易倾斜和卡钻事故多发等问题，在2个工程中试验应用了绳索取心钻进技术成孔，把打捞器中的柔性钢丝绳改为硬质铁管，解决了内管总成的打捞和投放问题。并采取了一些相关技术措施，取得了良好的钻进效果，2个深100 m水平孔均没有发生过孔内卡钻或其它事故，而且钻进效率高、岩心采取率高，达到了地质勘探的目的和要求。结合工程实践，介绍了在水平孔中采用绳索取心钻进技术的技术要求和工艺措施。

| Abstract: | In order to cope with accidents of hole deviation and drill pipe sticking in 100m deep horizontal drilling construc-tion, wire-line coring technology was applied by testing in 2 engineerings.By replacing flexible steel wire in fisher with iron pipe, the fishing and lowering of inner-tube assembly are solved.No accidents occurred in these 2 wells, and good drilling effect is achieved with high drilling efficiency and high coring rate.With the engineering cases, the paper introduces the technical requirements and process measures of wire-line coring drilling technology applied in horizontal well. |
