摘　　要：大孔径、高孔密防砂射孔技术主要适用于砾石充填防砂的油井 ,它有利于降低充填防砂井的充填压力 ,提高油井产能。 2 0 0 2年在草 13区块实施大孔径、高孔密防砂射孔作业 9井次 ,降低施工压力 8～ 14MPa ,日产油量增加6 .8t。固井质量分析表明 ,大孔径、高孔密防砂射孔对套管和水泥环未造成损害 ,是一种具有广阔应用前景的先进射孔工艺。Bighole highshotdensity sand control perforation technique is suitable to oil wells with pack gravel for sand control. The pack pressure of these wells for sand control will be reduced and productivity of oil wells will be improved using this technique. Nine welltimes in Cao 13 block in 2002 have been implemented with the results of operating pressure reducing 8～14MPa and daily oil production increasing 6.8t. Analysis on cement job quality shows that it is an advanced perforation technique and it didn′t damage the casing and cement sheath.
