FIELD: oil and gas industry.SUBSTANCE: method of well side bore completion includes the following stages: landing of multilateral well connector in the main well bore to a depth where main bore pressure is ca. 6,000 psi or more. This multilateral well connector includes main tube branch and side tube branch; main branch fixation in the main wellbore; side branch installation in a side wellbore; insertion of tool in the main or side branch; main branch stabilisation against side branch by a stabiliser during landing of multilateral well connector to the main wellbore; main branch stabilisation against side branch by another stabiliser during landing of multilateral well connector to the main wellbore. The other stabiliser is connected to the main branch or side branch in a point above bifurcation of the main and side branches.EFFECT: improved method.8 cl, 7 dwg |
