摘要： A compact, retrievable packer has a unitary mandrel body which is intersected by one or more longitudinal bores. The effective running length of the packer is reduced by an improved arrangement of packer components which serve multiple functions. The hydraulic actuator includes a cylinder housing which also serves as an internal slip housing, a lower element retainer, a piston extension, and a part of the release apparatus. A release sleeve serves as a part of the release apparatus, as a mandrel for engaging a locking slip, and forms a fixed boundary of the hydraulic pressure chamber. The effective running length of the packer is further reduced by making the upper wedge for reacting the setting forces as an integral part of the packer mandrel body.

摘要： A device for guiding the lower end of a pipe string, or the like, past an upwardly facing shoulder in a well in which rotation of the pipe string is prohibited. When the guiding device lodges on such shoulder, the pipe string is lifted and lowered a few times, this reciprocating action actuating an indexing mechanism in the guide tool and causing the lower end of the guide tool to rotate so that a slanted guide surface thereon is brought around to the point of lodging to dislodge the guide tool from the shoulder and guide the pipe string therepast.

摘要： A sintered metal screen is releasably suspended from a packer mandrel by a locking mandrel and a landing nipple. The sintered metal screen and locking mandrel are retrievable with the assistance of a running tool which is insertable into the bore of the locking mandrel. According to this arrangement, the sintered metal sand screen may be removed and replaced without retrieving the packer or the production tubing. In one embodiment, the sintered metal screen is enclosed within the bore of a sliding side valve. The sliding side valve may be opened and closed as desired for selectively admitting formation fluid from various producing zones, or for isolation of a damaged screen. In another embodiment, an auxiliary sintered metal screen is inserted into the bore of a primary screen, for example, a conventional wire-wrap sand screen. The sintered metal sand screen is thus interposed in the flow path for screening out sand fines which would otherwise be conducted because of damage to the primary screen caused by corrosion or sand erosion.

摘要： A sand screen having a plurality of sintered, substantially spherical plastic members covering a perforated mandrel is releasably suspended from a packer mandrel by a locking mandrel and a landing nipple. The sand screen and locking mandrel are retrievable with the assistance of a running tool which is insertable into the bore of the locking mandrel. According to this arrangement, the sand screen can be removed and replaced without retrieving the packer or the production tubing. In one embodiment, the sand screen is enclosed within the bore of a sliding side valve. The sliding side valve can be opened and closed as desired for selectively admitting production from various producing zones, or for isolation of a damaged screen. In another embodiment, an auxiliary sand screen having a plurality of sintered, substantially spherical plastic members covering a perforated mandrel is inserted into the bore of a primary screen, for example, a conventional wire-wrap sand screen. The auxiliary sand screen is thus interposed in the flow path for screening out sand fines which may be conducted through the wire-wrap screen because of screen damage caused by corrosion or sand erosion.

摘要： Sensors are attached directly to portions of the sand screen of a gravel packing assembly, with connectors to the sensors run through elements of the screen that are hollow for that purpose. The hollow element can be the trapezoidal wire that is circumferentially wrapped to form the outer screen or one of the outer spacers used to provide a stand-off of the wire from the underlying tubing. Sensors can detect such conditions as pressure, temperature, flow rate, density, etc., and can provide real-time information on the effectiveness of gravel placement during packing and on well conditions during production.

摘要： A surface controlled subsurface lateral branch safety valve provides flow control for each branch wellbore in a multilateral well. In a described embodiment, a completion system for a well having an intersection between parent and branch wellbores includes an apparatus having multiple passages formed therethrough. One passage provides fluid communication between opposite ends of the apparatus in the parent wellbore, and another passage provides guidance for drilling the branch wellbore. The apparatus further includes a flow control device, such as a surface controlled subsurface safety valve, which selectively controls fluid communication with the branch wellbore.

摘要： The flow apertures of a perforated mandrel are temporarily sealed by plugs which are made of a sacrificial material, for example, zinc, aluminum and magnesium. The sacrificial plugs prevent dirty completion fluid from passing through and in and out of the screen as it is run into the hole, thereby protecting the screen from plugging. During the time the screen mandrel is temporarily sealed by the sacrificial plugs, cleaning fluid is circulated through a work string and is returned through the annulus between the screen and the open well bore for removing filter cake, drilling debris and lost circulation material. After the annulus has been cleaned, the annulus is filled with an acid solution or caustic solution, which dissolves the sacrificial plugs. In an alternative embodiment, each sealing plug has a body portion and a stub portion which project into the mandrel bore. The sealing plug body portion is intersected by a vent pocket which is sealed by the stub portion. The screen mandrel flow apertures are opened by mechanically shearing the stub portion of each sealing plug with a milling tool run on a concentric tubing string.
