Multi-Lateral Well System

摘要

A production system for use in a wellbore having a main bore with an axis, a lower lateral bore, and an upper lateral bore, includes a hollow whipstock with a central bore. The hollow whipstock is secured to the main bore between the lower lateral bore and the upper lateral bore. A sleeve assembly has a moveable inner sleeve with an outer diameter smaller than an inner diameter of the central bore of the hollow whipstock, and a moveable outer sleeve with an outer diameter larger than the inner diameter of the central bore of the hollow whipstock. A flow control valve is located in the main bore above the upper lateral bore. The flow control valve has an inner tubing member in selective fluid communication with the lower lateral bore and an annular conduit in selective fluid communication with the upper lateral bore.
