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.
