摘要： A method for removing a downhole tool from a well bore comprises consuming at least a portion of the downhole tool within the well bore via exposure of the tool to heat and a source of oxygen. Another method of removing a downhole tool from a well bore comprises exposing the downhole tool to heat and a source of oxygen in situ within the well bore to desirably consume at least a portion of the tool within the well bore.

摘要： A disposable downhole tool or a component thereof comprises an effective amount of biodegradable material such that the tool or the component thereof desirably decomposes when exposed to a wellbore environment. In an embodiment, the biodegradable material comprises a degradable polymer. The biodegradable material may further comprise a hydrated organic or inorganic solid compound. The biodegradable material may also be selected to achieve a desired decomposition rate when the tool is exposed to the wellbore environment. In an embodiment, the disposable downhole tool further comprises an enclosure for storing a chemical solution that catalyzes decomposition. The tool may also comprise an activation mechanism for releasing the chemical solution from the enclosure. In various embodiments, the disposable downhole tool is a frac plug, a bridge plug, or a packer.

摘要： The present invention is directed to disposable composite downhole tool formed of a resin-coated fiber. The fiber is formed of a degradable polymer, such as a poly(lactide) or polyanhydride. The resin is formed of the same degradable polymer as the fiber. It chemically bonds to the fiber, thereby making a strong rigid structure once cured. The fiber may be formed into a fabric before being coated with the resin. Alternatively, the fiber is formed of a non-biodegradable material.
摘要翻译： 本发明涉及由树脂涂覆纤维形成的一次性复合井下工具。 纤维由可降解聚合物如聚（丙交酯）或聚酐形成。 树脂由与纤维相同的可降解聚合物形成。 它与纤维化学键合，从而在固化后形成坚固的刚性结构。 纤维可以在涂覆树脂之前形成织物。 或者，纤维由不可生物降解的材料形成。

摘要： A downhole tool having a body or structural component comprises a material that is at least partially consumed when exposed to heat and a source of oxygen. The material may comprise a metal, such as magnesium, which is converted to magnesium oxide when exposed to heat and a source of oxygen. The downhole tool may further comprise a torch with a fuel load that produces the heat and source of oxygen when burned. The fuel load may comprise a flammable, non-explosive solid, such as thermite.

摘要： A method of treating a subterranean formation penetrated by a wellbore, according to which a tool is fabricated of a material that breaks up or dissolves in the presence of a fluid and is inserted in the wellbore for performing a function in the wellbore. The fluid is then introduced to the tool to break up or dissolve portions of the tool and the remaining portions of the tool fall to the bottom of the well.
