摘　　要：结合采油现场实际,通过综合分析滤芯失效的表现形式,将滤芯材质、主体管壁厚度、过水孔密度作为影响滤芯主体现场使用寿命的三个可靠性主导影响因素,合理确定位极,科学设计试验方案;通过对过滤器滤芯主体的筛选试验,确定了经济合理、满足现场需要的滤芯主体。采用新型滤芯主体实现了在保持注水流量的同时,提高了滤芯的承压强度,可靠性增强。新型滤芯主体在正常工作压力环境中,使用时间平均为30天,是改进前的3倍。采用可拆洗式滤网结构,更换滤网方便快捷,减少了工人的劳动强度,可有效节约滤芯的成本投入,推广应用前景广阔。Based on the on-site situation of oil production, the form of filter element failure is analyzed, thus defining three main tactors that intluence the reliability of on-site service life of filter element host. Then the testing plan is designed in a scientific way. By way of screening test, economical filter element host that satisfies the on-site needs is defined. The new type of filter element host maintains the water injection rate, and meanwhile, the bearing strength of filter element and the reliability are both enhanced. The service life of the new type under normal working conditions is 30 days on average, which is three times of that before modification. Removable filter screen is used to reduce the labour intensity of workers, and cut down the cost of filter element.
