摘要
冷采作为一种新的采油工艺 ,已成功地用于未胶结砂岩中的稠油开采。采用大孔径、深穿透、高密度射孔进行稠油出砂冷采时对射孔压力和射孔井段有特殊的要求 ,且要求平直的井身结构和大套管完井。
Cold production has been successfully applied to the heavy oil recovery in uncemented sandstones taking as a new production technology. It has special demands on perforating pressure and perforated interval, and it needs straight hole structure and well completion by big casing when using big aperture, deeppenetrating and high density perforation for cold production in sand production of heavy oil.
