摘　　要：方法　在现场调查和室内实验的基础上 ,研究各种防砂方法与油田地质及开发方式的适应性。目的　建立防砂方法优选技术评价模型和经济评价模型 ,使防砂方法在胜利油区疏松砂岩稠油油藏中得以应用。结果　在原油粘度高达40 0 0 0mPa·s的永 8 8井和永 8 平 1井采用防砂方法优选软件进行防砂作业后 ,取得了较好的防砂效果。结论　在出砂地层分级分类的基础上 。Method\ Based upon site survey and indoors' experiment, the adaptability of various sand packing methods on oilfield geology and development modes is studied. Purpose\ To establish optimal sand packing screening model and economic evaluation model, and to enable the selected method to be used in the whole suitable reservoirs of shenli oil province. Result\ Relative good results were obtained by applying this screening software in well Yong 8-8 and Yong 8-Ping1(viscosity up to \{40 000 mPa·s\}). Conclusion\ On the basis of classifying sand producing formations, optimal selection of sand packing can be achieved by applying mathematical means. \;
