摘要： A fracture oriented completion tool system for use in a casing string in a wellbore. The completion tool comprises a casing valve having a radioactive source therein, the orientation of which may be determined by use of a detector apparatus, such as a rotational gamma ray detector. The casing valve thus may be aligned with the fracture of a zone of interest in the well. A plurality of casing valves may be used, with at least one having a radioactive source. A swivel connection may be used to interconnect the casing valve so that housing ports therein may be aligned as the casing is run into the wellbore. In one preferred embodiment, the swivel connection is a locking swivel connection. A method of positioning a casing string in the well utilizing the completion tool is also disclosed.

摘要： A system is provided for gravel-packing a zone of a well. An operating string of the system includes a liner hanger setting tool. A liner string is concentrically disposed about the operating string and has its upper end detachably connected to a lower end of the liner hanger setting tool. The liner hanger setting tool includes a rotatable ball valve disposed in a housing bore thereof. The liner string and operating string are lowered together on an outer drill pipe string into the well until a liner hanger of the liner string is located at a desired location. Then the liner hanger is set within the well at a desired location in response to an increase in pressure within the outer tubing string. Then the ball valve of the liner hanger setting tool is opened in response to an increase in pressure within a well annulus. A concentric inner tubing string is lowered through the outer pipe string, then through a ball valve bore of the open ball valve and into operable engagement with an isolation gravel packer of the operating string. Gravel laden slurry is directed down the concentric inner tubing string to a zone to be gravel-packed, and return fluid returns through a tubing annulus between the concentric inner tubing string and the outer tubing string.

摘要： A stage cementer and inflation packer apparatus. The apparatus comprises a mandrel with an external closing sleeve and an operating sleeve interlocked therewith. Below the operating sleeve is an opening sleeve. The opening sleeve is mechanically acutated by a pump-down plug in a plug-operated embodiment or by a differential pressure acting on the opening sleeve in a hydraulically operated embodiment, to actuate the opening sleeve to allow inflation of the packer element. A back check valve prevents the packer from deflating. After the packer is inflated, additional pressure is applied which ruptures a rupture disc to open a port to the well annulus above the set packer element. Cementing may be carried out through this port, and after the cementing operating, a plug engages the operating sleeve to move the operating sleeve in the external closure sleeve, thereby closing the cementing port. After cementing is complete, the center components of the apparatus may be drilled out, leaving the external closure sleeve to permanently seal the cementing port.

摘要： A retrievable well packer includes a packer mandrel with an expandable packing element disposed about the mandrel. Upper and lower shoes are received about the mandrel above and below the expandable packing element for compressibly engaging the packing element. A slip assembly is received about the mandrel for anchoring the packer within the well bore. Upper and lower wedges are received about the mandrel above and below the slip assembly for wedging the slip assembly radially outward upon longitudinal compression of the packing element. The mandrel is nonrotatably connected to each of the upper and lower shoes and upper and lower wedges for preventing rotation of those components relative to the mandrel in the event the packer must be milled out of a well bore. The mandrel is initially releasably longitudinally locked relative to the lower wedge by a releasing collet attached to a lower end of the mandrel and having radially outward extending lugs received within a groove of the lower wedge. A releasing sleeve is initially releasably held in a lower position to hold the lugs of the releasing collet in the groove of the lower wedge.

摘要： A multiple stage inflation packer with secondary opening rupture disc. The inflatable packer comprises a case with a closing sleeve, an opening sleeve and a releasing sleeve therein. An opening plug is dropped into the casing string and is allowed to free fall, or is pumped down, to actuate the opening sleeve to allow inflation of the packer element. A back check valve prevents the packer from deflating. After the packer is inflated, additional pressure is applied which ruptures a rupture disc to open a port to the well annulus above the set packer element. Cementing may be carried out through this port, and after the cementing operation, a closing plug is pumped down the well casing behind the cement to actuate the releasing sleeve and move the closing sleeve to seal off the ports. Another check valve insures that pressure is equalized on both sides of the rupture disc as the packer is run into the well bore. After cementing is complete, the center of the packer may be drilled out, leaving the closing sleeve to permanently seal the ports.

摘要： Apparatus adapted to be lowered on a tubing string for setting a gravel pack at the bottom of a well. Conduits provide a gravel-slurry flow path from the bottom of the tubing to a screen which is suspended from a housing at the lower end of the conduits. A packer is provided between the tubing and the housing for sealing the well bore during gravel packing. When the screen hits the bottom of the well, a clutch connected between the housing and the conduit disengages to prevent transmission of tubing movement to the screen during the gravel packing process. Upon packing completion, tubing string rotation releases the screen to permit raising of the apparatus on the tubing string.

摘要： A casing inflation packer for use in a casing string in a well bore. The apparatus includes a housing connected in the casing string. An inflatable packer portion on the housing sealingly engages the well bore when inflated. An inflation passageway is defined between a housing central opening and the packer. A rupture disc is initially disposed between the central opening and the inflation passageway for preventing communication therebetween. The rupture disc ruptures in response to a first predetermined pressure, thereby placing the central opening in communication with the packer through the inflation passageway. A slidable control valve is disposed in the inflation passageway and is initially shearably held in an open position. Upon application of a second predetermined pressure across the valve, the valve is moved to a closed position, thus preventing overinflation of the packer and also preventing deflation thereof. A check valve allows fluid to enter the packer and acts as a backup preventing fluid from leaving the packer in the event of failure of the control valve. Another check valve provides pressure equalization between the packer and the well annulus as the apparatus is lowered into the well bore. The packer has an elastomeric packer element and metal reinforcing, such as a metal packer bladder, disposed inside the packer element.
摘要翻译： 一种用于井筒中套管柱的套管膨胀封隔器。 该装置包括连接在套管柱中的壳体。 当充气时，壳体上的充气封隔器部分密封地接合井眼。 在壳体中心开口和封隔器之间限定充气通道。 破裂盘最初设置在中心开口和充气通道之间，以防止它们之间的连通。 破裂片响应于第一预定压力而破裂，从而使中心开口与封隔器通过充气通道连通。 可滑动的控制阀设置在充气通道中并且最初被可变地保持在打开位置。 当跨越阀门施加第二预定压力时，阀门移动到关闭位置，从而防止封隔器的过度充气并且还防止其放气。 止回阀允许流体进入封隔器并作为备用件，防止流体在控制阀故障的情况下离开封隔器。 当该装置下降到井眼中时，另一个止回阀在封隔器和井环之间提供压力平衡。 封隔器具有弹性体封隔器元件和设置在封隔器元件内部的金属加强件，例如金属封隔器囊。

摘要： The present invention provides a cementing tool for cementing multiple stages within a well. The assembly includes a housing assembly which defines one or more cementing ports. A first sleeve assembly is retained within the housing and is movable from a first position, where the sleeve covers the port, and thereby precludes fluid flow therethrough, to a second position wherein the sleeve opens the cementing port. The apparatus also includes a second sleeve assembly which is movable from a first position away from the cementing port to a second position wherein the sleeve assembly covers the port. The first sleeve is cooperatively configured with the housing assembly to provide engaging surfaces which resist rotation of the first sleeve relative to the housing. Additionally, the first sleeve and the second sleeve assembly are configured to limit relative rotation when the two pieces are longitudinally adjacent one another.
