摘要： Methods of completing wells utilizing wellbore equipment positioning apparatus provide repositioning of sand control screens and perforating guns without requiring movement of a packer in the wellbore. In a preferred embodiment, a well completion method includes the steps of lowering a packer, positioning device, sand control screen, and perforating gun into a well, perforating a zone intersected by the wellbore, expanding the positioning device, and positioning the sand control screen opposite the perforated zone.

摘要： A service tool for use in completion operations includes a fluid control apparatus therein. The apparatus permits variable regulation of fluid flow downhole, selective opening and closing of multiple fluid ports in the apparatus, protection against overpressurization and communication with the earth's surface. Each of these functions is accomplished by displacing a member of the apparatus with an electromechanical device. In particular, data transmission is performed by displacing the member relative to a fluid port to thereby produce pressure pulses in a fluid flowing therethrough.

摘要： A screen provides increased erosion resistance and collapse resistance without uneconomical overcompensation and without requiring an increase in the screen's outer diameter. In a preferred embodiment, a sand control screen has a support material radially between a tubular base pipe and a filtering portion. The support material radially outwardly supports the filtering portion to help prevent radially inward collapse of the filtering portion. In another preferred embodiment, a screen has a coating applied to a filtering portion's exterior surface. The coating may alternatively or combinatively provide erosion resistance, radially inwardly retain a support material, and selectively vary flow through the filtering portion.

摘要： A production sub carrying a plurality of annular locator rings is coupled in series relation with downhole production equipment. A collet latch assembly including fixed and floating collet members is connected to a down hole service tool and is inserted into releasable coupling engagement with the annular locator rings of the production sub. Resilient finger portions of the fixed collet are alternately supported and unsupported by the floating collet to establish positive engagement with a selected one of the annular locator rings or to permit passage of the latch assembly with respect to the locator ring. The foregoing arrangement provides positive restriction to longitudinal movement of a work string which allows a downhole service tool attached to the work string to be selectively positioned at predetermined operating locations relative to downhole equipment. Additionally, the positioning assembly provides partial restriction to longitudinal movement of a work string for activating the motion-compensating equipment of a floating service vessel so that ocean heave or swell does not cause excessive longitudinal excursions of a downhole service tool attached to a service string which is supported by the floating vessel.

摘要： A proppant slurry screen apparatus and associated method of using it prevent sticking of a service tool during proppant slurry delivery to a subterranean wellbore after failure of a crossover portion of the apparatus. In a preferred embodiment, a proppant slurry screen apparatus has a tubular crossover member with an internal flow passage, circulation port, and side wall outlet openings, first and second coaxial tubular structures, the first tubular structure extending above a packer and having a radial port which provides fluid communication between the wellbore above the packer and an annular flow passage between the first and second tubular structures, and a tubular screen positioned between the first and second tubular structures adjacent the port and operative to screen proppant from the proppant slurry.

摘要： A method of deploying a well screen and associated apparatus provide convenient and economical completion operations within subterranean wells. In a disclosed embodiment, a method of positioning a screen includes attaching the screen to a completion string before stimulation operations are performed on a formation. Initially, the screen is spaced apart from the formation. After the stimulation operations are performed, the screen is positioned opposite the formation and packers are set above and below the screen. In order to thus position the screen, a work string is inserted into the completion string, the screen is attached to the work string, and the screen is released from the completion string. After the packers are set, the work string may be retrieved and the formation placed in production. The screen and packers prevent flow of particulate material from the formation into the completion string. Other methods are provided as well.

摘要： Gravel slurry is pumped through the longitudinal service bore of a tubular service tool which is extended through a packer mandrel and into the seal bore of a tubular cross-over tool which is disposed in the annulus between the service tool and a well casing. Slurry flow is directed from the service bore through a cross-over flow port of the cross-over tool into the annulus between the cross-over tool and the well casing. The gravel-laden slurry is injected through casing perforations into the surrounding earth formation at a high flow rate. After the fracture operation has been completed, the slurry flow rate is reduced substantially and a gravel pack is accumulated in the annulus between the well screen and the well casing. Slurry liquid is circulated through the well screen into a return flow bore of the service tool. The slurry liquid is then conducted through a longitudinal cross-over flow passage formed through the cross-over tool into a return annulus defined between the service tool and the packer mandrel. The slurry liquid is then conducted through the annulus between the service tool and the well casing to the surface.

摘要： A single bore packer is modified by a dual flow seal unit for gas lift completion. This permits the operator to inject lift gas into the upper casing annulus at the well head, bypass the hanger packer and conduct the lift gas into the suspended production tubing below the fluid level. The dual flow seal assembly is sealed internally against the packer mandrel, with the lift gas being conducted through a bypass flow passage between the seal mandrel and the packer mandrel, and being discharged into the lower casing annulus through a discharge port formed through the packer mandrel below the packer seal element package. The hang weight load of the production tubing is decoupled with respect to the packer seal elements by a set of internal ratchet slips which transfers the hang weight load from the packer mandrel onto the anchor slips and well casing at a location below the seal element package.

摘要： A positive position indicating tool includes a snap ring mounted on a mandrel. The snap ring is blocked on the mandrel by a shear sleeve and provides a positive stop to upward retraction of a work string. The snap ring is shearably released when it is desired to retract and/or retrieve the work string. The snap ring is supported on the mandrel by a shear sleeve which is locked onto the mandrel by shear pins. An annular recess is formed in the sidewall of the mandrel between the shear pins and the snap ring. As the tension loading on the work string increases above the combined shear strength of the shear pins, the shear sleeve and positive indication snap ring are displaced downwardly along the mandrel, and the snap ring moves into the annular recess and contracts radially out of obstructing engagement. The snap ring incorporates alternating slots which permit it to expand and recover without permanent deformation. The slots are angularly displaced from a large angle at the back of the ring to progressively smaller displacement angles toward the open end portions of the ring. The slots are more widely separated and are shallower in the high stress regions of the snap ring, and are more closely located and are deeper in the low stress regions of the ring.
摘要翻译：正位置指示工具包括安装在心轴上的卡环。卡环通过剪切套筒在心轴上阻塞，并提供正向停止以向上收回工作串。当需要缩回和/或取回工作串时，卡环可以被剪切地释放。卡环通过剪切套筒支撑在心轴上，剪切套筒通过剪切销锁定在心轴上。在心轴的侧壁在剪切销和卡环之间形成环形凹部。当工作线上的拉力负载增加到剪切销的组合剪切强度以上时，剪切套筒和正指示卡环沿着心轴向下移位，并且卡环移动到环形凹部中并径向收缩以阻止接合。卡环包含交替的槽，允许其膨胀和恢复而不会永久变形。槽在环的后部从大角度角度地移位到朝向环的开口端部逐渐变小的位移角。狭缝分布更广泛，在卡环的高应力区域较浅，并且在环的低应力区域中更靠近并且更深。
