摘要： A plug retrieval tool includes a mandrel lowerable into a wellbore. A retrieval head is coupled to the mandrel for selectively latching onto a plug. A shroud is telescopically coupled to the mandrel about the retrieval head and moveable repeatedly between an extended position below the retrieval head for displacing debris on the plug and a retracted position for moving the retrieval head closer to the plug to latch onto the plug. A resistance mechanism provides a resistance to moving the shroud each time the shroud is moved toward the retracted position.

摘要： A downhole clean out tool includes a housing coupled to a downhole conveyance and defining an inner volume that includes a flow path that extends from an uphole end to a downhole end that includes a fluid inlet; a first flow port oriented towards the downhole end and configured to fluidly couple the flow path to an annulus of the wellbore through the housing; a seat formed in the housing and configured to receive a member inserted into the wellbore such that the flow of the wellbore fluid is diverted from the flow path, through the first flow port, to the annulus, and to the fluid inlet based on the member seated on the seat; at least one screen positioned in the inner volume; and a second flow port oriented towards the uphole end and configured to fluidly couple the flow path to the annulus of the wellbore.

摘要： A junk crusher device for crushing junk in a fluid stream includes a circular plate and a shaft. The circular plate includes fluid stream discharge holes and a bearing. The shaft is disposed within the bearing and includes detachably connected tear blades that are configured to rotate with the shaft. The junk crusher device further includes an impeller, hydraulically driven by the fluid stream, configured to rotate the shaft, an internal housing including fixed blades, and a body configured to receive the internal housing such that the internal housing is secured to an interior of the body. The rotating tear blades and fixed blades are configured to crush junk in the fluid stream. The fluid stream discharge holes disposed in the circular plate are configured to filter crushed junk.

摘要： Disclosed herein are compositions, processes, and systems for deploying and creating a temporary fluid barrier at an interface between a high fluid conductivity zone and a lower fluid conductivity zone. The disclosed compositions include mixtures of solvents and biodegradable non-spherical particles, wherein the particles include a coating that may slow or inhibit degradation, for example by hydrolysis, of the particle. The disclosed particles are designed to possess sufficient flexibility to traverse the high conductivity zone.

摘要： A system includes a solids catcher that is centered with respect to a central axis of a tubing. The system includes an inner annulus, an outer annulus, and a chamber between the inner annulus and the outer annulus. A solids accumulation zone is formed in the chamber. A pump disposed offset from the central axis of the tubing. The pump is fluidly connected to the solids catcher through the outer annulus. A fluid stream carrying solids flowing from the pump. The fluid stream carrying solids is configured to follow a path delimited by the outer annulus and the chamber until the fluid stream deposits the solids in the solids accumulation zone and departs the solids catcher via the inner annulus into a tubing.

摘要： Various systems, methods, and devices are disclosed for handling contaminants in a wellbore or riser. A washpipe debris trap (WPDT) traps contaminants traveling up a wellbore from a downhole location, and the WPDT may serve as an indicator for a breached screen in a downhole location. A marine riser reversing tool (MRRT) may reverse the flow of fluid between a workstring conduit and an annulus between the workstring and the wellbore such that fluid rises to the wellhead with greater velocity. A bi-directional chamber trap (BDCT) may be utilized in a wellbore operation to remove contaminants from a fluid.

摘要： A downhole well conditioning tool for self-stimulating a well is provided. The down hole tool is a multi-stage stacked self-exciting tool that can alter a relatively steady flow of incoming fluid into pulsating fluid streams of rapidly cycling high and low pressure without the use of moving internal parts. The downhole tool can include a first stage operative to receive a steady flow of pressurized fluid though an inlet and discharge a pulsating fluid flow and a second stage connected to the first stage and operative to receive the pulsating fluid flow from the first stage and increase the pulsations of the fluid flow before the pulsating fluid flow is discharged out of the second stage.

摘要： A single trip method allows for perforation, cleaning the annular space around the perforations in an existing tubular and then delivering a sealing material through a combination tool that is used for cleaning and then sealing. For sealing the tool is positioned by the lowermost perforations with a bypass around spaced seals that straddle the outlet port for the sealant. There is an open bypass through the tool and around the spaced seals as the sealant is delivered so that the sealant goes above and below the spaced seals. The open bypass allows the tool to be repositioned as the sealant is delivered. The tool is removed with the string. A separate through passage is selectively opened for removing excess sealant in conjunction with the bypass passages. The sealant can be squeezed with a seal on the string to effectively close the bypass letting pressure through the through passage squeeze.
