防砂工艺是解决油井出砂问题的一项重要措施,但目前防砂费用高,且油井产量降低、甚至导致停产等问题仍未解决。尽管防砂工艺不断改进和完善,其缺点日趋减少,但仍会不同程度地减低油井产量。携砂生产通过制定有效的出砂管理制度,根据油层出砂不同状况,采用防、排砂泵进行携砂采油,并在此基础上确定经济合理、环境允许的砂处理方法。这样不仅可节约大量的热采、防砂材料及施工费用,而且能提高产能。
Sand control technology is an important measure to solve the problem of sand production in oil wells. However, the current cost of sand control is high, and the production of oil wells is reduced, and even the problems of stoppage of production are still unresolved. Despite the continuous improvement and improvement of the sand control technology, its shortcomings are diminishing day by day, but the production of wells will still be reduced to some extent. Carrying sand production through the development of an effective sand management system, according to the different conditions of sand production, the use of anti-sand pump for sand carrying oil recovery, and on this basis to determine the economic and environmental allowable sand treatment methods. This will not only save a lot of heat recovery, sand control materials and construction costs, but also increase productivity.
