摘要
研制开发出一种新型阴离子表面活性剂压裂液,确定了该压裂液的配方。大量的室内试验表明,该压裂液具有防膨性能好、滤失小、易破胶、携砂性能好、摩阻低和对储层伤害低等优点。目前该压裂液已成功应用于苏东地区6口双层改造井,增产效果明显。该压裂液适合用于对苏里格东部岩屑砂岩储层进行改造。
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.
