Fluidic Modulators and Along String Systems |
| 摘要 |
A well system includes a first fluidic modulator (FM) located at the bottom of the tubular string and a repeater fluidic modulator (FM) located in the tubular string between the first FM and the surface, the repeater FM including a body forming a flow aperture between an inlet and an outlet, the flow aperture providing a constriction to a fluid flowing axially through the tubular string, and a moveable portion operable to alter the flow aperture. To create a modulated pressure pulse the moveable portion may be for example radially shifted in the flow aperture, rotated in the flow aperture, or the rotation of the moveable portion in the flow aperture may be controlled. |

1. A well system, comprising:
a tubular string extending from a surface into a wellbore; a first fluidic modulator (FM) located at a bottom of the tubular string; and a repeater fluidic modulator (FM) located in the tubular string between the first FM and the surface, the repeater FM comprising a body forming a flow aperture between an inlet and an outlet, the flow aperture providing a constriction to a fluid flowing axially through the tubular string; and a moveable portion operable to alter the flow aperture. |
