Abstract: A method for enhanced degradation of a cutting structure on a drill shoe is provided. The cutting structure may be degraded at an accelerated rate after achieving a desired objective. Degradation of the cutting structures on the drill shoe may facilitate the eventual drill out of the drill shoe. In one embodiment, a method of degrading the cutting structure includes operating the drill shoe using a reduced flow rate of drilling fluid. In another embodiment, a method of degrading the cutting structure includes operating the drill shoe at an increased rotary speed. In yet another embodiment, a method of degrading the cutting structure includes operating the drill shoe with an increased weight on bit. In yet another embodiment, a method of degrading the cutting structure includes any combination of one or more of the enhanced degradation methods described herein.
Abstract translation: 提供了一种用于增强钻头上的切割结构的劣化的方法。 切割结构可以在实现期望的目标之后以加速的速度降级。 钻具上的切割结构的降级可能有助于最终钻出钻床。 在一个实施例中，降低切割结构的方法包括使用钻井液的流量降低来操作钻具。 在另一个实施例中，降低切割结构的方法包括以增加的旋转速度操作钻床。 在另一个实施例中，降低切割结构的方法包括以钻头重量增加操作钻床。 在另一个实施方案中，降解切割结构的方法包括本文所述的一种或多种增强的降解方法的任何组合。

Abstract: EARTH REMOVAL MEMBER WITH FEATURES FOR FACILITATING DRILL 5 Embodiments of the present invention generally relate to an earth removal member (1) with features for facilitating drill-through. In one embodiment, an earth removal member (1) for drilling a wellbore with casing or liner includes a tubular body (5) and a head (10). The head (10) is fastened to or formed with an end of the body (5), has a face (1Of) and a side (lOg), is made from a high strength material, and has a port 1o (1Op) formed through the face (10f). The earth removal member further includes a blade (15a,15b). The blade (15a,15b) is formed on the head (10), extends from the side (10g) and along the face (10f), and is made from the high strength material. The earth removal member further includes cutters (20) disposed along the blade (1 5a, I 5b); and a nozzle adapter (450). The nozzle adapter (450) has a port (450p) formed therethrough, is is longitudinally and rotationally coupled to the head (10), and is made from a drillable material. The earth removal member further includes a nozzle (100) disposed in the adapter port (4 50p) and fastened to the nozzle adapter (450). K1 5a 20 lOf 15r 15b lot 1op 1og
