钢丝取心器,是为提高破碎地层岩心采取率而设计的专用取心工具.我们曾在庙沟矿区硬、脆、碎的地层中钻进,用它取心,使采取率得到保证.用于补采,尤为理想.在同一矿区,还用于钢粒钻进,以对付胶结很差的砾石层,使进入岩心管的砾石全部取上.钢丝一般用2～3个回次都不会断.今年在冲击回转钻进中应用它,效果也很好.钢丝取心器可配用于一般单管或双动双 Wire coring device is a special coring tool designed to improve the core recovery rate of the crushed formation.We used to drill in the hard, brittle and broken strata of Miaogou Mining Area, and use it to coring to ensure the adoption rate. In the recovery mining, especially in the same mining area, but also for the drilling of steel to cope with poor cementation gravel, so that all the gravel into the core tube to take the wire generally use 2 to 3 times will not return Off this year in the impact of rotary drilling in the application of it, the effect is also very good. Wire take-off can be used with general single-tube or double-acting
