NOTES
The tools that norm
ally require centring are Fluid F
low &
Identification tools. Additionally tools that m
easure the casing or tubing i.d. m
ay also need centralising. Centralisers diam
eters are matched to the body size of the tools w
ith the total num
ber required estimated from
the toolstring weight.
CC
L response is best if these are run eccentred. In the case of high pressure wells w
here weight bars are required to
assist the tools enter the well a rigid toolstring needs excessive centralisation and these are therefore best run eccentred.
Knuckle Joints provide toolstring flexibility to allow
part of a string to be centred & the rest eccentred. T
wo joints should
always be used &
these should be separated by a tool whose position does not m
atter, e.g. Gam
