【 摘 要 】

The paper considers method of computer simulation of well multilateral junctions corresponding to TAML Level-4. The base stages of algorithm of stress-strain condition calculation of cased main and side pipes are described. Durability of junction depending on internal pressure is established in a kind of functional dependences. The influence of side pipe thickness and whipstock angle on junction deformation is researched.
