| Abstract: | The concept of volume fracturing has brought about a technological revolution in the exploration and development of unconventional oil and gas resources. The theory of micro-fracture imbibition and displacement has changed the traditional understanding of the fracturing fluid industry. In this paper, the Gemini surfactant was synthesized by the molecular design, and the acetylenic alcohol nanosilica oil release agent was optimized and matched, then the oil displacement surfactant fracturing fluid was developed. Compared with the conventional guanidine gum fracturing fluid system, the system has better dispersion and wettability change performance, with an osmotic efficiency of 38% and an oil displacement efficiency of more than 20%. The on-site test shows that the oil speed is fast, the output at the initial stage of production is high, the water content is low, and the effect of increasing production is obvious. |
