ANALYSIS ON MECHANICAL BEHAVIOR OF SALT
ROCK WITH BARE HOLE |
|
|
|
|
Abstract The creep of salt rock is very harmful in petroleum drilling. The creep of salt rock is calculated and analyzed by finite element method. The relations among shrinkage of bare hole radii，creeping shrinkage time，hole depth，density of drilling fluid，in-situ stresses coefficient，non-uniform coefficient and time are given. The calculation results are successfully applied into Tarim oil field.
