| description | The invention relates to a technique used acidity surfactant to remove oil well blocking and its formula and manufacturing method. The feature of the acidity surfactant formula is that its material weight ratio is as follows: polyoxy propylene-polyoxy ethylene glycerin ether 10-40%, polyoxy propylene-polyoxy ethylene phenol amine resin 10-45%, FC-NO1 fluorocarbon surfactant 0.0001%-0.035%, FC-3B fluorocarbon surfactant 0.0001%-0.05%, hydrochloric acid 3-10%, nitric acid 2-10%, and water 30-55%. The feature of the technique is as follows: the made-up 0.4%-0.6% acidity surfactant can be injected from hollow while running; then it can be replaced by 10-20m3 clear water. The invention has good effect and can improve yield. |
