Detailed Description

First, use: for the test oil, oil, find water, cards and other craft column plugging, the use of anchor claw bite force to overcome the string of peristalsis.

Second, the structure and working principle:

Mainly by the anchor body, the anchor claw, righting block, spring seals, bolts and other components.

Increase from the hydraulic tubing, anchor claw in the liquid under the action of compression spring, so that the anchor claw radial introduced in sufficient pressure, the anchor claw firmly stuck in the tube wall, thereby preventing axial movement of pipe. Play a role in anchoring tubing. Let go tubing fluid pressure, the spring claw anchor automatically receive additional stuck.

Main technical parameters:

Technical Parameters	Maximum outer diameter	Minimum path	Anchor diameter	Starting pressure	Working pressure	Total length	Suitable for casing inner diameter
Specification model	mm	mm	mm	MPa	MPa	mm	mm
KDB80/48	80	48	35	0.25	50	350	101.60
KDB105/48	105	48	40	0.26	50	350	118-121
KDB110/48	110	48	50	0.27	50	375	118-124
KDB114/48	114	48	50	0.30	50	528	121-127

Four characteristics:

Hydraulic anchor: anchor using high strength stainless steel body, the anchor claw special treatment, the anchor claw reset spring stainless steel with high elastic springs, it has high strength, with sleeve anchor, reliable, long-term work in the underground will not fail due to return spring or claw anchor with the anchor body between the sealing surface with the anchor claw does not lead to rust back position, arising from the packer string can not be re-opened and so on.
