WELL TESTING & COMPLETION TOOLS
Hydraulic Anchor
-
Usage
Prevent of down-hole tools axial movement. It is used as down-hole string tools anchor, which for oil layer hydraulic fracture, water well increasing of water, hydraulic jetting sand, cutting or jetting sand of perforation etc.
-
Structure feature
Inject high pressure liquid by tubing, anchor finger compress spring by hydraulic pressure to casing surface and clamping on it, which could overcome axial push in operation, and stable down-hole string tools.

Full-bore Compensating Pipe
-
Usage
Full bore compensating pipe is crucial accessory of downhole string tools. It is as compensating system which for string tools length changes cause of internal & external pressure or temperature changes, could prevent danger from axial power changed a lot.
Connect with mechanical or hydraulic packer, which could be used for fracturing, acidification or other increasing production operation. Meantime, for water injection, gas injection as well.
-
Structure feature
Full bore compensating pipe is always connected on top of packer. Down-hole production (operation) string tools pull back cause of temperature or pressure changed a lot, string tail anchor by packer or hydraulic anchor, string tools pull back power on compensating pipe. When the power is higher than cutting power to cut shear pin, expanding mandrel moves longer with seal sleeve which could compensate of string tools, then to achieve compensating function.

Retrievable Bridge Plug
-
Usage
Retrievable bridge plug is one type of seal and block tool in oilfield. It is mainly composed by setting system, anchor system, sealing system and so on. Apply special self-locking system, reliable double side pressure bearing function, no need to cement coating on surface, could achieve of reliable sealing. Retrievable bridge plug could set by cable setting tool or hydraulic setting tool, could unset for retrievable of repeat use. It could be used for temporary blocking, permanently blocking, cementing and so on, also could work with other string tools for selective blocking or snubbing operation etc. Retrievable bridge plug is one type of downhole blocking tool which is safety and reliable, cost low, function variety and wide application range.
-
Structure feature
Setting: setting by cable. Connect Retrievable bridge plug with setting tool and run to determined position. Fire powder stick in setting tool to produce HTHP air, which could force floating piston of setting tool and get relative movement with mandrel, push bridge plug slip to casing surface and compress bridge plug rubber element to seal casing annulus. Meanwhile, bridge plug internal structure is self-locking, abruption of tensile bar (ring) to pull out of setting tool, and bridge plug block determined position strictly in well.
Unsetting: Run professional unsetting tool through tubing and drill pipe, catch bridge plug unsetting sleeve and pull up of string tool, open bridge plug self-locking system, rubber element return back and slip back to case, bridge plug unset and assly pulled out to surface with tubing.

Mechanical Releasing Tool
-
Structure feature
When Packer or Bridge plug run to determined section and after setting, pull up string tool to cut shear pin, disconnect string tools above Packer or Bridge plug, to achieve releasing.

Differential Pressure Releasing Tool
-
Structure feature
When Packer or Bridge plug run to determined section and after setting, increase pressure in string, force cylinder move down to cut shear pin, release control of head finger below top coupling, pull up string tool to disconnect from top of tool, achieve of releasing.
