diverter overshot packer made in china

The diverter assembly is the uppermost component of the riser system.It is not used to shur or seal the well completely, but to either direct the teturing drill fluit or control the blowout and surface layer gas, when encountering the gas, the diverter can close off around drillpipe or casing,and open the special direction vent line on board at the same time

Cameron diverters are fully customizable for your floater and jackup rig operations, respectively. Designed for reliable, efficient use, each system consists of a housing, outlet valves, running tools, controls system, diverter assembly, overshot packers, and storage skids.

The CF-A diverter supports up to 75.5-in rotary tables and has a hang-off capacity of up to 2,500,000 lbm. It uses a single annular packing element with a pressure rating up to 500 psi. The CF-A diverter features four hydraulic locking dogs that reduce hosing and simplify operation. It eliminates the need to secure hoses to the diverter assembly while providing hydraulic fluid for the operations.

The CF-B diverter supports up to 47-in rotary tables and is qualified up to 2,000 psi. Packers can be split and hinged to allow them to be changed out with pipe in the hole. J-slot type running tools are entirely mechanical and require no hydraulics.

D eep well programs on the Arabian peninsula present unique challenges during the initial phase of drilling operations.Shallow gas pockets may be encountered that require managedwell bore control that is not currently available on existing land rigs.Utilizing feedback from the Saudi Arabian Oil Company (SaudiAramco), Dril-Quip, Inc. has developed the Arabian DiverterSystem (ADS) to address these challenges.The ADS (patent pending) is a portable diverter installed on theconductor and establishes a pressure-tight seal to enable controlleddiversion of any gas pockets that might be encountered. This divert-er system integrates three elements – the diverter housing, packingelements and an overshot spool-type connector – into a unitizedprotection device. The ADS incorporates safe, reliable field-proventechnology and performance features into a 500-psi-rated workingpressure design.Elastomer packers in the diverter close and seal around pipesuspended through the rig’s rotary table, isolating the rig floor fromfluids and gases flowing from the well bore. Large outlets locatedbelow the packers control and divert the flow to a designated area.Hydraulic controls for the diverter system are incorporated into therig’s BOP control system. Valves with hydraulic actuators aremounted on each of the diverter outlet lines to control the move-ment of fluids and gases through the system.The handling and test tools provided facilitate testing, operationand maintenance of the system.

FEATURES• Large-bore diverter accommodates 36" drift• A range of split insert packers provides well bore protection during both drilling and casing operations• Split packer design also facilitates running selected packer elements through a 37-1/2" rotary table• Split insert packer design simplifies installation via weight-set, lock-ring style auto-locking components; no hydraulics required• Overshot radial bolt connector features quick, easy make-up using standard impact wrenches• Overshot connector packer seal is hydraulically energized for reliable control of the well bore fluids• Engineered, designed and operated in accordance with applicable API industry standards• Adaptable to most land drilling rigs• Complete ADS diverter and valve system available from single source (Dril-Quip)

Main PackerThe Main Packer is housed in the main body of the diverter, andconsists of a tubular elastomer seal with metal rings molded oneach end. The one-piece packer is retained in the main body ofthe diverter by the packer lockdown, retaining and load ring.The Main Packer functions the insert packers when the diverteris closed. Hydraulic pressure deflects the packer toward the bore,which in turn deflects each of the insert packers installed. TheMain Packer is only removed during maintenance operations. 10" Split Insert PackerSolid Packers and Split Insert PackersThe Solid and Split Insert Packers land in the main body ofthe diverter and are designed to close and seal around variouspipe sizes. The packers consist of a tubular elastomer seal withmetal rings molded on each end. The Split Insert Packers aresplit in half so that they can be installed or retrieved whilepipe is suspended through the rotary table. A spring-loadedlockdown ring is bolted to the top of the packer and retains it inthe previously installed larger packer. Tapped holes in the topof the lockdown ring permit the swivel insert retrieving rodsto release the lockdown ring and recover the packer assemblywhen necessary.

Lifting-Lower and releasing overshot is a fish tool in the casing which fishes fractured tubing and drill string. If fish drill string is stuck heavily and hard to complete fish work, while need to release fish, may get back the tool by bumping drill string down and lift directly.

Lifting-lower and releasing overshot is composed of top sub, bowl, guide pin, guide sleeve, joint sleeve,plug, roller pin, slip, guide, as shown in the figure. Box thread of top sub is connected with drill stem, pin thread is connected with the bowl, The bottom of bowl is connected with guide, An inner cone in the bowl matches the slip, Box thread of guide sleeve is connected with joint sleeve, track trenches are milled on another outer surface: three long trenches and three short trenches act as guiding and reversing ,When guide pin locates in long trench is in the condition of fish ,When guide pin locates in short trench is in the condition of release, Joint sleeve is two petals formation ,It makes slip and guide sleeve connection and by roller pin act as bearing, The inner surface of slip has fish thread, guide is on the bottom and can make fish introduce into slip successfully.

Completion equipment was then installed to hydraulically isolate the junction. This was achieved by running single string production packers below the junction in each lateral. Separate tubing strings were then tied-back, through the junction, to a dual string production packer above the junction. This resulted in the level 5 junction, ie.; a junction with mechanical and pressure integrity. The well was then completed as a dual string completion to surface.

4 \ Diverters for Jackup & Platform Drilling Units KFDJ Diverter Systems KFDJ Diverter Complete protection while running casing strings and drilling hole is provided by a full range of insert packer sizes, all of which use a "J" type running tool. Available with a rotating insert which provides low pressure packoff on the kelly or drill pipe during drilling. Features The fixed support housing, a proprietary feature, is securely bolted to the rotary beams and provides fixed outlets for flowline, fill-up line and vent lines. The support housing allows installation of outlets up to 20" diameter to virtually any configuration. Diverter, spacer spool and overshot packer assembly may be pulled or run without connecting or disconnecting the flowline, fill-up line and vent lines. Mudline suspension hangers and bit sizes up to 27.41" for 37-1/2" rotaries or 36.41" for 49-1/2" rotaries can be run without removing the diverter assembly. Diverter, spacer spool and overshot packer each fit through a 37-1/2" rotary table. Minimum bore through the standard support housing is 36-1/2" ID for the 37-1/2" in rotary installation. Optional 37-1/2" bore is available. The overshot packer on the bottom of the diverter spacer spool assembly reduces the nipple-up time normally required to weld flanges or hubs to casing.
