    摘要:

    为探明矿产储量和矿带产状,进行了水平绳索取心钻进试验。由于试验场地地质条件复杂,钻头不能很好的适应地层,未取得理想钻进效果。通过对绳索取心钻头的选型试验,重点分析了水平钻进对钻头的影响。结合完孔后的钻孔轨迹,逆向分析了水平钻进与钻孔轨迹的关系。选出了适合该矿区的钻头,并提出了钻头的改进方法及防止钻孔弯曲的建议。

    Abstract:

    To prove the mineral reserves and the occurrence of mineralization belt, wire-ling coring drilling test was made. Because of the complex geological conditions, the used bit was not well adapted to make good drilling results. Through the selection test of impregnated diamond bit and the drilling track, analysis was made on the impact of horizontal drilling on the bit. Based on the borehole track, reverse analysis was made on the relationship of horizontal drilling and borehole track, suitable bit for the mine geological conditions was selected with improvement methods and suggestions on preventing hole bending put forward.
