摘　　要：西非A 油田平均作业水深1 500-1 700 m.油田分6 套层系开发,生产井共采用了压裂充填、膨胀筛管、优质筛管3种防砂方式.通过分析油田储层物性及开发井实际生产数据,从防砂效果、表皮因数及单井产能3 个方面对3 种防砂方式的效果进行了评价.研究结果表明,在合理生产制度下,3 种防砂方式均能有效防砂;从降低表皮因数、提高油井产能方面分析,优质筛管防砂在该地区更具优势;压裂充填方式可承受更大的生产压差.The average operating depth of deepwater Oilifeld A in West Africa is 1 500 to 1 700 m. The oilifeld is developed by six series of strata. The production wells adopt three sand prevention measures of frac-pack, expandable screen pipe, and high-quality screen pipe. By analyzing the properties of oil reservoir and the actual production data of development wells, the effects of the three sand prevention methods are evaluated from three aspects of sand controlling result, skin factors, and single well productivity. The research results show that all of the three methods can effectively prevent sand under a reasonable production system; to analyze from reduc-ing skin factors and increasing well productivity, high-quality screen pipe is more advantageous in the region; frac-pack can withstand greater differential pressure of production.
