3 . - , TAML-4. -, , .The present study focuses on the analysis of finite difference stems joint design of multilateral wells by computer simulation and must answer a series of questions that relate to the establishment of the optimum design parameters for multilateral wells TAML-4. The paper examines the impact of angle ofwhipstock that is used to build a sidetrack, and the wall thickness of the casing of sidetrack on the characteristics of the stress strain state of the junction of the main and lateral bores of multilateral wells.
