RTTS Packer for Testing 

1. Apllication

RTTS is mainly consititute of Y221 mechanical slip packer and used for formation testing in high temperature and pressure, oil extraction, water injection, water exploration, pl ing, squeezing acidification, fracturing and so on.

2. Main structure and tech parameter

1) Main structure

As shown in the figure,RTTS packer is mainly composed of upper joint, hydraulic anchor, rubber barrel, slip holder, slip, slip bracket, reversing friction block, outer central pipe, inner central pipe and so on.

2) Lifting height

2 7/8TBG and 2 7/8UPTBG tube:

 H=0.0408L + 14

3 1/2TBG tube:

 H=0.0284l + 14

( — RTTS packer lifting height,cm

— RTTS packer setting depth,m

14— RTTS packer reversal distance, slip idle stroke, rubber compress distance, cm)

3) Main tech parameter
