稠油热采井细粉砂防治是目前公认的技术难题,迄今,国内外尚处于探索阶段。辽河油田一些主要稠油生产区块受细粉砂严重干扰而无法投入正常生产。为了有效地遏制细粉砂砂害,确保原油上产,辽河油田“八五”后期历时两年的攻关与研制,并经180多井次现场试验,终于使细粉砂得到基本治理,使大批油井重新恢复生产。 Heavy oil thermal recovery wells fine silt prevention and control is currently recognized as a technical problem so far at home and abroad are still in the exploratory stage. Some major heavy oil production blocks in Liaohe Oilfield are seriously disturbed by fine silt and can not be put into normal production. In order to effectively curb the fine sand and sand damage, to ensure crude oil production, Liaohe Oilfield “85” lasted two years of research and development, and more than 180 well tests in the field, and finally make fine silt get basic control, So that a large number of oil wells to resume production.
