Key words: well, BHA, differencial sticking, prevention.
This work is devoted to prevent BHA differential stickingas a result of its sticking to well`s wall. We give the methodology and some research results of various factors influence on BHA sticking to a crust by means of contact area determination and the interaction force of pipes with a crust. We show the most significant actions to prevent BHA differential stickingof the boring tool when the boring tool stops working.
