PULSE WIDTH MODULATED DOWNHOLE FLOW CONTROL
First Claim
1. A downhole flow control system, comprising:
- a flow control device including a flow restrictor which variably restricts flow through the flow control device, and an actuator which varies a vibratory motion of the restrictor to thereby variably control an average flow rate of fluid through the flow control device.

Abstract
A pulse width modulated downhole flow control. A downhole flow control system includes a flow control device with a flow restrictor which variably restricts flow through the flow control device. An actuator varies a vibratory motion of the restrictor to thereby variably control an average flow rate of fluid through the flow control device. A method of controlling flow in a well includes the steps of: installing a flow control device in the well, the flow control device including a flow restrictor which variably restricts flow through the flow control device; and displacing the restrictor to thereby pulse a flow rate of fluid through the flow control device.
