摘　　要：吉林油田新立、新北地区黑帝庙油层平均埋藏深度300～450 m,孔隙度为25%～35%,渗透率一般为(70～500)×10-3μm2,属于典型的浅埋高孔高渗油气藏,固相堵塞损害严重,影响了勘探开发效益。通过对储层岩心分析,运用理想充填理论和敏感性预测方法,优化暂堵技术,形成了理想充填油层保护技术,岩心渗透率恢复值达到85%以上,现场应用测试表皮系数为0.402,很好地解决了浅埋高孔渗黑帝庙油藏保护的技术难题。The burial depth of Heidimiao reservoirs is 300-450 metres, the porosity is 25%-35%, and the permeability is(70-500)×103 μm2, which is of high-porosity and high-permeability shallow reservoirs.However, in this reservoir, it isdamaged by particle plugging that affects the development benefit severely.In this paper, through core analysis, idealpacking theory and prediction of reservoir sensitivity, the ideal packing reservoir protection technology is developed, whichthe permeability recovery rate is 85% in lab.The application result shows that the skin coefficient turns to 0.402 that satisfiesthe demands of reservoir protection in Heidimiao reservoirs.
