Abstract: By incorporating a dissolvable or degradable material into the wiper dart and/or float equipment, a fluid can be pumped during the cement phase (or spotted by other means) to begin degradation of the dissolvable material. Once the material is dissolved, a flow path is exposed, allowing communication to the backside or formation of the wellbore through the plug set and shoe track.

Abstract translation: 通过将可溶解或可降解材料结合到擦拭器镖和/或浮动设备中，可以在水泥相期间（或通过其他方式点亮）泵送流体以开始降解可溶解材料。 一旦材料溶解后，就会露出流动路径，从而允许通过插塞组和鞋轨道与背面或形成井筒。

Abstract: Methods of plugging a hydrocarbon well by using degradable plugs are provided. When the plug is no longer needed, a degradation fluid or fluids are pumped downhole under high pressure, typically via jet, such that the degradation fluid provides an erosive force to the degradable plug, thus both speeding its degradation and preventing or minimizing the leaving of solid plug material remnants in the well.
