    摘要： An aperture design minimizes erosion on the surrounding casing and to the aperture itself and is particularly effective in fluid injection wells where large volumes of fluids over a long period of time with entrained solids are expected to be pumped through. The preferred design is an elongated shape with a flaring wider in the downhole direction. The downhole end of the opening features an exit that flares in the downhole direction with multiple slopes with an arc transition. Other options for the opening configuration are envisioned.

    摘要翻译： 孔径设计使周围套管和孔本身的侵蚀最小化，并且在流体注入井中特别有效，其中期望长时间内具有夹带固体的大量流体被泵送通过。 优选的设计是在井下方向上具有更宽的扩口的细长形状。 开口的井下端部具有出口，其在井下方向上以多个具有弧形转变的斜面向外突出。 设想开启配置的其他选项。

    摘要： An element including an undercut in the element extending from an innermost surface of the element radially outwardly into the element, and a pathway intersecting the undercut and extending from the undercut to an outermost surface of the element, the pathway fluidly connecting the outermost surface of the element to the undercut prior to setting of the seal.

    摘要： A system includes a tubular having an interior surface, a longitudinal axis, a flowbore, and a main portion having a first inner diameter. A vibration inducing feature is disposed along the interior surface of the tubular and is immovable with respect to the tubular, and has a second inner diameter within the tubular that is different than the first inner diameter. The feature has a beveled first end surface and a beveled second end surface, the beveled first and second end surfaces longitudinally displaced from each other. The feature is configured to increase turbulence within the flowbore and configured to dissuade a capture of objects passing therethrough. A sensing system includes a sensor arranged to detect vibration within flow passing the vibration inducing feature, and is configured to output a command signal in response to sensed data reaching a threshold value or indicative of a predetermined pattern.
