摘要： The present disclosed technology relates to a downhole tool activation device, and a method of using the device, where the valve is configured to open when the counter device has moved an activation distance in an activation direction, a piston engaged with the counter device, having a wellbore pressure from a fluid source applied to a first side, and a pressure in a fluid reservoir applied to the second side, the piston configured to move a step distance in a first direction when the wellbore pressure exceeds the pressure in the fluid reservoir, and configured to move a step distance in an opposite direction driven solely by a greater pressure in the fluid reservoir than the wellbore pressure, and a flow restrictor in fluid communication with the fluid reservoir and fluid source, configured to restrict the flow of fluid between the fluid source to the fluid reservoir.

摘要： Dissolvable pump down devices, dissolvable pump down assemblies, and methods to propel a bottomhole assembly through a lateral section are presented. A dissolvable pump down device includes an engageable portion, and one or more expandable pieces that are initially in a first position before the dissolvable pump down device is deployed in a wellbore, and configured to expand from the first position to a second position in response to a force generated by fluid flow of fluid through the wellbore. A diameter of the expandable pieces while the expandable pieces are in the first position is less than the diameter of the one or more expandable pieces while the one or more expandable pieces are in the second position. The engageable portion and the one or more expandable pieces are configured to dissolve after the dissolvable pump down device is positioned at the desired wellbore location.

摘要： A tool comprises a tool body having a bore, a secondary chamber within the tool body, a flow port between the bore and the secondary chamber; a cover component within the bore moveable between at least two positions along the length of the bore, and a control arrangement connected to control movement of the cover component within the bore. The control arrangement comprises a moveable piston and a guide component, one of which has a track and the other has a protruding element received in the track. In a first position, the cover component covers an entrance to the flow port, so that fluid flowing along the bore may not flow into the flow port. In a second position, the cover component does not cover the entrance to the flow port, so that fluid flowing along the bore may flow through the flow port and into the secondary chamber.

摘要： An assembly and a method of setting a plug in a borehole. The assembly includes a first lock, a second lock axially separated from the first lock. The plug is located between the first lock and the second lock. A bore of the assembly passes through the first lock, the second lock and the plug. A ball is dropped through the bore and activates the first lock and the second lock to allow the plug to rotate into a set configuration in the borehole.

摘要： Embodiments described herein provide systems and methods for minimizing deceleration of downhole tools when the downhole tools are pumped down into wellbores through drill pipe in an untethered manner. For example, embodiments described herein include a hydraulic downhole tool deceleration system that includes a hydraulic decelerator configured to be affixed to a downhole tool string pumped down through drill pipe during operation. The hydraulic decelerator is configured to contact a hard shoulder while traveling through the drill pipe, and to limit an initial magnitude of deceleration of the downhole tool string caused at the initial moment of contact of the hydraulic decelerator against the hard shoulder.

摘要： A downhole blowout preventer has a blowout preventer tubing string containing a circulation unit, a packer unit and a pressure-building unit connected in sequence from top to bottom. The pressure-building unit is configured to be activated in response to a command, so as to build up pressure in a space inside the blowout preventer tubing string. The packer unit is configured to be activated when a pressure in said space reaches a first predetermined value, so as to seal an annulus between said blowout preventer tubing string and an external casing or borehole. The circulation unit is configured to be activated when the pressure in said space reaches a second predetermined value, thereby creating a circulation path between an interior and an exterior of the blowout preventer tubing string. The first predetermined value is less than the second predetermined value.

摘要： A device such as a smart dart is configured to reversibly engage and disengage with a seat in a tubing string. In an engaged configuration, pressure applied above the device forces a first seat component to engage a second seat component. The interaction of the first seat component and the second seat component under pressure produces an inwardly radial circumferential force that grips the device within the seat and may also form a seal between the device and the seat.

摘要： A bottomhole assembly (BHA) located on a conveyance string for actuating downhole tools in a wellbore, such as sleeve valves. The bottomhole assembly has a shifting tool that is capable of being hydraulically actuated independently of a mechanically actuated treatment tool also located on the BHA. The shifting tool has hydraulically actuated shifting dogs for engaging with the sleeve valves, and a shifting-assist mechanism for applying a downhole force on the BHA. The treatment tool is mechanically actuated via manipulation of the conveyance string to isolate the wellbore, for example to treat a formation through an opened sleeve valve. A hydraulically cycled flow control valve can be located on the BHA for more convenient control of the fluid flow and pressure in the BHA. The BHA can also have a repositioning mechanism for positioning the shifting tool downhole of an opened sleeve valve without requiring repositioning of the entire BHA.
