Abstract: In recent years, with the development and improvement of fracturing fluid technology, the technology of fracturing fluid technologies, such as guar gum, Synthetic polymer, and surfactant are basically sophisticated and applied in special reservoir bed or conditions in which the process requires. This paper elaborates the technical development and application of CNPC fracturing fluid and believes that the main technologies diversification of fracturing fluid, their adaptability to highly mineralized water and recycling are determinants to meet needs for fracturing fluid technology and control costs over a period of time. The technical indicators of low damage, low-cost, high efficiency and environmental protection are future development direction of the fracturing fluid. It gives insights about the technical conditions of fast dissolution and continuous mixing of thickening agent, and the new ideas about the technology of high temperature fracturing fluid. It also appeals to establish the unconventional reservoir fracturing fluid and its damage evaluation methods as soon as possible to standardize and guide the development of fracturing fluid technology.
