| Abstract: | Fast speed of acid-rock reaction and short effective distance of acidizing fluid, lead to worse stimulation effect on the acidification construction. To summarize and analyze both foreign and domestic treatment, namely the method of add to the gelling agent in acid to improve the retarding performance. In this paper, the basic composition and properties of four main gelling agents used at home and abroad were summarized, and discussed the development trends of gelling agents in future. This craft provides approaches and basis for domestic oilfield enterprises in acidification construction. |
