摘　　要：新疆石油管理局针对勘探开发中油气层保护、防止油气层污染的问题,同西南石油学院合作进行了屏蔽暂堵技术的研究工作。经现场1000多口井的实际应用表明,该项技术具有对钻井液污染小、屏蔽暂堵效果好、减少了对储层的损害、施工简单、成本低、便于推广等优点。An emulsion well completion fluid with shielding temporary sealing property is proposed against the special points of Xiazijie oil field of Xinjiang . It contains super fine calcium carbonate as bridging and filling particles , and sulfonated asphalt as sealing agent . Tests at over 1000 wells indicated that this system improve the recovered permeability of cores .
