    摘要: A method of anchoring a housing to an inner diameter of a tubing string can include: installing an anchoring assembly at an end of the tubing string, the anchoring assembly comprising: a body; the housing; an installation sleeve; a rotating sleeve in threaded connection with the housing and the installation sleeve; and a plurality of anchoring buttons located within a plurality of cutouts on the housing; causing movement of the body along a longitudinal axis of the tubing string towards the end of the tubing string that causes the plurality of anchoring buttons to circumvolve around a pin and an edge of the anchoring buttons lockingly engages with the ID of the tubing string after circumvolving; releasing both of the installation sleeve and the rotating sleeve from engagement with the tubing string, the body, and the housing; and removing the installation sleeve and the rotating sleeve from the anchoring assembly.

    摘要: A downhole tool can be used as a fill valve to circulate a fluid, such as a spacer fluid, through the tool. The tool can include a top and bottom flapper valve and an inner and outer sliding sleeve. The sliding sleeves can be shifted together to allow the top flapper valve to close. Continued shifting of the inner sleeve can cause the bottom flapper valve to close. A cementing operation can then be performed through the tool. Sealing elements can be located between the outside of the inner sleeve and inside of the outer sleeve. Sealing elements can also be located between the outside of the outer sleeve and the inside of a tool mandrel. The sealing elements can prevent debris from becoming lodged within the tool.

    摘要: A stage cementing tool for a wellbore comprises a tool body defining a flow port in a wall thereof. The tool body and wellbore define an annulus therebetween. A setting sleeve compresses a packer element as it moves from the first to the second position. The packer element expands radially outwardly to engage the wellbore as a result of the compression applied by the setting sleeve. A pump-out plug in the tool body is expellable into the annulus upon the application of pressure in the tool body after the packer element engages the wellbore.
