摘要： An erosion migration arrangement includes a tubular having a window therein. A body positioned within a portion of the window is configured to sacrificially erode in response to a slurry flowing through the window to thereby migrate a location of impact on a member positioned downstream of the window.

摘要： Slip elements for a bridge plug include an inner body portion that is substantially formed of a material that is degradable by dissolution in response to a dissolving fluid and a hardened, resilient, radially outer contact portion. The outer contact portion includes a plurality of openings that function as stress risers. The inner body portion may be formed of magnesium powder.

摘要翻译： 用于桥塞的滑动元件包括内部主体部分，其基本上由可响应于溶解流体和硬化的，弹性的径向外部接触部分溶解而降解的材料形成。 外部接触部分包括用作应力梯度的多个开口。 内部主体部分可以由镁粉形成。

摘要： Downhole hanger systems and methods for hanging a first structure from a second structure in downhole environments are described. The systems include a first structure and a second structure, with the first structure disposed within the second structure. A composite joint is arranged on an outer surface of the first structure. The composite joint is formed of a material configured to be fused to both the first structure and the second structure and form a hanger joint having a shear strength of at least 2 ksi when the material is fused to the outer surface of the first structure and an inner surface of the second structure.
