摘要: 在深部地质岩心钻探中,绳索取心是最常用的钻进工艺。由于绳索取心钻进环状间隙小,需要采取加大钻头的方式,解决泵压高、“激动”压力大造成孔壁失稳等问题。深孔施工在不下套管的情况下直接将钻头加大到上一级口径,可以解决环状间隙问题,还能多出一级备用口径。通过对绳索取心钻杆能力进行分析,研制了跨口径系列绳索取心钻具,并在实践应用中不断改进,为深部地质岩心钻探的钻孔结构设计和复杂地层钻进提供了保障,应用效果良好。为满足地热钻探的长孔段取心要求,提出了大口径绳索取心钻具的设计方案,进一步拓展了绳索取心工艺的使用范围。Abstract: Currently in the field of deep geological core drilling,wire-line core drilling is the most commonly used drilling technology. Owing to annular size of wire-line core drilling is smaller, have no choice but to adopt the method of enlarging the drill bit, solve problems such as high pump pressure and high excited pressure causing hole-wall instability. In deep hole construction, the problem of annular clearance can be solved by increasing the drill bit to the upper caliber without lowering the upper casing. There is also an additional level of spare caliber. This article analyzes the drill pipe capacity of wire-line coring drilling, The theoretical basis for cross bore wire-line coring tools is proposed. The drilling tool has been designed and processed in a complete set and continuously improved in application practice. It provides great help for drilling structure design and complex formation drilling in the field of deep geological core drilling, Achieve good application results. In order to meet the requirements of long hole coring in geothermal drilling, a design scheme for large diameter wire-line coring tools was proposed, further expanding the scope of use of wire-line coring.
