中文摘要: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 construction, 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. |
