Steam Assisted Gravity Drainage (SAGD) is the main thermal technique for in situ heavy oil recovery in Canada. This technique employs two horizontal wells that are supported against collapse by the installation of screen liners called Sand Control Devices (SCDs). SCDs are designed to (1) control sand production while allowing the flow of reservoir fluids into the well; and (2) allow the discharge of fine materials to avoid plugging of the screen and pore spaces behind the screen.

蒸汽辅助重力泄油（SAGD）是加拿大稠油热采的主要技术。该技术采用两口水平威尔斯井，通过安装称为防砂设备（SCD）的筛管内衬来支撑水平井以防坍塌。SCD的设计目的是（1）控制出砂，同时允许储层流体流入井中;（2）允许排出细粒物质，以避免堵塞筛管和筛管后面的孔隙空间。
