摘要： An expandable threaded connection between segments of expandable tubulars. The present invention utilizes two complementary thread segments. The first segment of the threaded connection utilizes standard box and pin threads. In the second segment of the threaded connection, material is removed from the stab flank of the pin threads to reduce the standard width of the pin threads, while the box threads of the second segment are standard thread width. The use of the reduced thread width in the pin threads of the second segment allows for a loose fit between the pin threads of the second segment and the box threads of the second segment. The loose fit between the pin and box threads of the second segment allows radial and axial movement between those threads without causing disengagement of the threaded connection during the expansion process.
摘要翻译：可膨胀管段的可膨胀螺纹连接。本发明利用两个互补螺纹段。螺纹连接的第一段使用标准的盒和线螺纹。在螺纹连接的第二段中，材料从销螺纹的刀头侧面移除，以减小销螺纹的标准宽度，而第二段的箱形螺纹是标准螺纹宽度。在第二段的销螺纹中使用减小的螺纹宽度允许在第二段的销螺纹和第二段的箱螺纹之间松动地配合。第二段的销和箱螺纹之间的松配合允许在这些螺纹之间的径向和轴向运动，而不会在膨胀过程中导致螺纹连接脱离。

摘要： A packing assembly which is connectable to reeled tubing and which can be inserted in and pushed through a wellbore tube by the reeled tubing. The packing assembly is hydraulically set in a locking and sealing position in the wellbore by fluid introduced from the reeled tubing and, after use, is hydraulically released and removed from the wellbore. An actuating apparatus is provided for hydraulically actuating the packing assembly and can be converted in a manner to pull the packing assembly from the wellbore. Prior to the removal of the packing assembly from the wellbore, the wellbore fluid pressure is equalized across the packing assembly.

摘要： A latch for releasably anchoring well tools at a preselected downhole location within a well bore. The latch includes collet heads which are sized to be received within an annular recess. The downhole location is defined by the annular recess and a no-go shoulder which limits the movement of the latch into the well bore. The latch is activated by application of force in one direction after contact with the no-go shoulder. A first set of pins is sheared during activation of the latch to prevent retraction of the collet heads from the recess. A second set of pins is sheared by applying force in the opposite direction to allow release of the collet heads from the recess.
摘要翻译：用于将井具可释放地锚定在井眼内的预选的井下位置处的闩锁。闩锁包括夹头，其尺寸被设计成容纳在环形凹部内。井下位置由环形凹部和不会脱离的肩部限定，该限制了闩锁进入井眼的运动。在与不脱离肩膀接触后，通过在一个方向施加力来启动闩锁。在闩锁的启动期间剪切第一组销，以防止夹头从凹部中退回。通过在相反方向施加力来剪切第二组销，以允许将筒夹头从凹槽中释放出来。

摘要： A tubular member, to be a segment of the casing string, is provided with a polished bore at its upper end and a locking profile at its lower end. The locking profile includes a bearing shoulder and internal left hand threads for coaction with a latching mechanism. Another tubular member, to be a segment of the production tubing, has groups of circumferentially separated flutes to (1) maintain concentricity of the tubing segment, (2) provide axial flow passages between the segments, and (3) provide support for components of the tubing segment. A tubular packing mandrel, mounted on flutes, carries external annular packing for sealing engagement with the polished bore. The lower end of the packing mandrel defines an annular valve seat; and a tubular valve closure member, mounted in sliding, sealing relation on the tubing segment, has a coacting upward facing valve seat. A valve spring urges closure of the valve closure member. Lower flutes define a bearing shoulder for coaction with the casing shoulder to support the tubing string. A latching mechanism includes circumferentially separated axially extending spring fingers carrying external threads for coacting ratcheting and threaded engagement with the profile threads. When the tubing string is lowered to the support position provided by the bearing shoulders, the tubing segment is locked within the casing segment.

摘要： A well tubing extension joint including a trash barrier. A top sub having an internal locking recess is connected on the upper end of a well packer mandrel. A trash barrier is connected on the lower end of an upper tubing string for releaseably engaging the top sub to permit the upper tubing string to move longitudinally relative to the packer and packer top sub. The trash barrier includes a body having locking collet fingers for releaseably locking the body in the top sub at the locking recess. The body has external rings seals for sealing with the top sub and an internal wiper seal for sealing with the upper tubing string extending through the body. The upper tubing string has a seal moveable along the packer bore and includes a tubing joint coupling which is releaseably connectible in the trash barrier body permitting the trash barrier to be run into the well and landed and locked in the top sub, and thereafter the tubing string is released from the body for longitudinal movement in sealed relationship through the wiper seal. In two forms of the invention the upper tubing string is connected to the trash barrier assembly body only by shear pins. In the other form of the invention, the coupling is connected by shear pins and a threaded connection.

摘要： A well sealing system for blocking fluid flow through an annulus partially defined by a tubing string disposed within a casing string. A metal seal ring is compressed and radially expanded to form a primary metal to metal seal between the exterior of the tubing string and the interior of the casing string. A production well packer and packing rings are carried by the tubing string to form secondary elastomeric to metal seals between the tubing string and casing string. Backup rings are provided to control the extrusion of the metal seal ring while it is compressed and radially expanded. A protective cylinder is also provided to prevent damage to the packing rings and the metal seal ring while the tubing string is lowered through the bore of the casing string. The protective cylinder assists in setting the production packer while the metal seal ring is being compressed.

摘要： A latching seal unit for use on a tubing string in a well bore for connecting the tubing string into a well packer having a receiving head provided with one or more latching lugs, the seal unit including a top sub connectable on a tubing string, a tubular locator body connected with the top sub, a latching collet cage having straight-slots mounted on the locator body formed of circumferentially spaced collet fingers defining longitudinal slots and guide surfaces providing entrances into the slots and a latching recess along each of the longitudinal slots, the longitudinal slots being sized to form an interference fit with the latching lugs in the well packer, and the latching recesses being sized to receive the latching lugs, a tubular seal body connected with the locator body, annular seal elements assemblies on the seal body for sealing with a packer bore, and a mule-shoe guide on the seal body below the seal element assemblies. The collet cage may be free to rotate or locked against rotation on the seal unit body. The coaction between the collet cage and packer lugs provides a surface detectable indication of proper landing of the unit in a packer. The seal unit is useable with prior art packers and has the advantages of both collet and straight-slot type prior art seal units.

摘要： A dual string well packer which is anchored at a downhole location within the bore of a well casing string by relative longitudinal movement between the primary tubing string and the secondary tubing string. The well packer is set by applying tension via the secondary string. The well packer is released from its downhole location by applying tension via the primary string. The invention is particularly adapted for use in well completions that are subject to thermocycling such as steam injection wells. However, the anchoring and releasing mechanism of the present invention can be readily adapted for use with any dual string well packer. The present invention includes an improved method for well completion, minimizing tubing handling requirements during the installation and removal of the production tubing strings and associated dual string well packer.
