【摘要】 防砂工艺和效果与完井方式有密切的关系，提出并分析了四种完井方式．在条件允许的情况下，采用裸眼砾石充填进行先期防砂完井，可以获得较好的油、气流通能力和较厚的砾石层，可下入大直径的滤砂管，这种完井方法有利于防砂．对于用射孔方式完成的井，如果预测有出砂倾向，则应采用大直径套管作为生产套管，以高密度射出大直径的孔．对于胶结差的疏松产层则建议采用渗透性人工井壁完井．更多还原

【Abstract】 There is a close relation among sand control technique, sand controlling effect and completion technique. Four types of sand control completions are analyzed. If open hole gravel pack is used, a better flow conductivity for oil and gas and thicker gravel packing zone can be obtained. and a large-diameter screen will be suitable for sand control wells. If sanding tendency for perforated well is forcasted, the large-diameter casing is taken as the production casing, so as to complete holes with high perforation dencity and large perforation diameter. It is suggested to make a permeable artifical borehole wall if the pay bed is formed by unconsolidated sandstone.更多还原
