Water power<hydraulic> casing centralizer
Product Design Features
In the horizontal well, for action of gravity, cashing pipe deviated to the end of well hole to make the cement sheath too thin or even without it, then the quality of well cementation is not good. Water power (hydraulic) centralizer, The righting arm with a layer of a layer of set of similar antenna method, compressed the righting arm when it’s into the well, small diameter, easy into the well.
When the centralizer to be the right position, casing pressure makes the righting arm force outward expansion of casing centralizer, improve the effect of cementing quality.
