| Abstract: | The acid fracturing for carbonate reservoir in Tahe Oilfield requires that the acid fluid has the performances of high temperature resistance,delaying reaction rate,and reducing filtration rate. So it is need to develop a new long-acting acid fluid system. By optimizing polymers,gel breakers,and cleanup additives,the new long-acting acid fluid system formulation was obtained as follows： 20% HCl ＋ 0. 9%polymer A ＋ 2. 5% corrosion inhibitor H ＋ 1. 0% cleanup additive C ＋ 1. 0% demulsifier Q. The evaluation experiments were carried out and the results showed that the long-acting acid fluid system had good ability of heat resistance and shear resistance,low corrosion rate,good performance of retarding and cleanup. |
