Problems solved by technology

[0004] Providing the flow control device and packer as separate modules adds to the overall complexity and cost of the tool string
Additionally, since the flow control devices and packers are separate components, the overall length of the tool string is increased, especially when there are a large number of flow control devices and packers placed on the tool string

Embodiment Construction

[0013] In the following description, numerous details are set forth to provide an understanding of the invention. However, it will be understood by those of ordinary skill in the art that the invention may be practiced without relying on these details and that various changes and modifications from the illustrated embodiments are possible.

[0014] As used herein, the terms "above" and "below"; "upper" and "downward"; "upper" and "lower"; "upwardly" and "downwardly"; Similar terms for the relative positions of upper and lower are used in this description to more clearly illustrate some embodiments of the invention. However, when applied to equipment and methods used in deviated and horizontal wells, such terminology may denote a left-to-right or right-to-left relationship as appropriate.

[0015] Figure 2 shows a downhole toolstring 200 (intelligently completed component) including an integrated flow control device and isolation element, according to one embodiment. "Isolati...

Abstract

The invention relates to equipment used in well, which comprises a working barrel, a flow control device arranged on the working barrel, and an isolated component which is arranged on the working barrel and used for the isolation between zones of the well.

Description

technical field [0001] The present invention relates to an apparatus having an integrated flow control device and spacer element disposed on a mandrel. Background technique [0002] As part of completing the well, various components are set into the wellbore to perform different tasks. Two such components include flow control devices and packers. Flow control devices control flow between various parts of the well, for example, between a reservoir and a flow conduit (eg, production tubing, injection tubing, etc.), or between other parts of the well. [0003] Flow control devices and packers are typically provided as separate components on a downhole toolstring. For example, if figure 1 As shown, a conventional downhole tool string deployed in a well 100 includes two sets of equipment 102 , 104 . The first set 102 includes a packer 106 and a separate flow control device 108 arranged as two separate modules. The two modules are typically connected to each other using a thr...
