胜利油田开发的主要层系中,有些油层砂岩胶结疏松,在生产中常常引起地层出砂,影响油井正常生产。因此,防止油井出砂是本油田开发过程中需要解决的问题之一。当前挖掘油田潜力,防砂是一项较为重要的措施。自1965年以来,先后开展了十余种防砂方法试验,经现场365口井842井次的防砂,成功率约70％,见到了一定的防砂效果,初步确定有五种方法可用于出砂井防砂。这五种方法是:
Among the major strata developed in Shengli Oilfield, some sandstones in the reservoirs are loosely cemented, often causing sand production in production and affecting the normal production of oil wells. Therefore, preventing sand from oil wells is one of the problems to be solved in the development of this oilfield. Current excavation of the potential of the oil field, sand control is a more important measure. Since 1965, more than ten kinds of sand control tests have been carried out successively. After 842 wells of 365 wells in the field have been successfully sandblasted, the success rate is about 70%. Some sand control effects have been observed. Five methods have been initially determined for sand production wells Sand control. These five methods are:
