Abstract
The guide apparatus for tubular members prevents buckling, when a snubbing unit inserts the tubular member into a well. The guide apparatus includes a lower slotted cylinder having a plurality of rib extensions projecting upward so as to form lower slots, and an upper slotted cylinder a plurality of complementary rib extensions projecting downward so as to form upper slots. The lower slotted cylinder engages the upper slotted cylinder by sliding the rib extensions into the upper slots and the complementary rib extensions into the lower slots. The guide apparatus coordinates the slotted cylinders with traveling slip bowls and stationary slip bowls of a snubbing unit so that relative movement of the slotted cylinders corresponds to movement of the slip bowls. The rib extensions, the complementary rib extensions, or both support the entire length of tubular member between the slip bowls, when being snubbed.
