Abstract: |
A new kind of anion surfactant fracturing fluid is developed and it’s formula is confirmed. According to the tests,this anion surfactant fracturing fluid has advantages such as good anti-dilatation property,low leavings, breaking easily,good ability of taking along seeds,low friction resistance,and low damage to formation, etc. It has been proved by successful fracturing in six double deck wells. This anion fracturing fluid is very suitable for the gas sandstone formation reforming in the east of Sulige. |
