发明名称 PULSE WIDTH MODULATED DOWNHOLE FLOW CONTROL
摘要 A pulse width modulated downhole flow control. A downhole flow control syste m includes a flow control device with a flow restrictor which variably restric ts 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 flo w 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.
