钻井液性能

二、用法及用量
　　 钻遇目的层前50米，在泥浆中加入3～5% FQ-1油层保护剂，在钻至目的层时，再补充1～2% FQ-1油层保护剂，即可达到很好的油层保护效果；在修井作业中，在修井液中加入3～5% FQ-1油层保护剂，也可达到很好的油层保护效果。
三、包装及储运注意事项
　　 1、采用三合一袋包装，内衬聚乙烯薄膜袋，每袋净重25kg。
　　 2、储存在阴凉、干燥、通风处。
　　 3、远离火源。

FQ-1 reservoir protecting agent is oil soluble polymers and additives by special process prepared has good oil solubility and dispersion of oil, mainly used for reservoir protection in drilling and workover operation well repairing additive.
