SMART ACTUATION MATERIALS TRIGGERED BY DEGRADATION IN OILFIELD ENVIRONMENTS AND METHODS OF USE
摘要
<p>Downhole devices including degradable materials and methods of using such devices to control downhole operations are disclosed. A method for controlling a downhole operation includes providing a device that includes a degradable material downhole; and degrading the degradable material to activate the device. Activation of the device may result in a displacement or flow (actuators) that may be used to control or monitor (sensor) a downhole oilfield operation. A downhole device for use in a well penetrating a formation includes, in part or in whole, a degradable material.</p>
