Considering the complex conditions in the thermal production wells with steam injection and the stress variation of the casing strings during the operation which is not fully taken into account in strings design, a study on mechanical stability of strings with complex constraints in well completion is conducted. A stress computing model for the strings under the complex constraints is deduced and built. Making the real horizontal-thermal well B05-P2 as an example, the effects from the intricate conditions including well structure and high temperature steam on the stability of the pipe string are studied.
