A type of zirconium-organic cross-linking agent with excellent temperature resistance and delaying performance was prepared for acid fracturing fluid system. The factors influencing on the synthetic process of the zirconium-organic cross-linking agent were investigated and the optimum condition was obtained: 5% zirconium oxychloride, 20% ligands, reaction temperature 50~55°C, reaction time 4.0~5.0h. Then the best technology for zirconium-organic cross-linking agent and the laboratory evaluation for the acid fracturing fluid system were studied. The results showed that using the cross-linking agent can obviously improve the temperature resistance, delaying performance and the shearing resistance of the acid fracturing fluid system. Meanwhile, the zirconium-organic cross-linking agent had excellent gelout performance and sand-carrying performance, which can satisfy the fracturing operation requirement for the reservoirs below 100°C.

Abstract When cold fluid is injected into low-temperature, low-pressure, low-permeability reservoirs containing wax-bearing heavy oil, cryogenic paraffin deposition and heavy oil condensation will occur, thus damaging the formation. Moreover, the formation pressure coefficient is low and the working fluid flowback efficiency is low, which affects the fracturing stimulation effect. Therefore, an in situ heat/gas clean foam fracturing fluid system is proposed. This system can ensure that conventional fracturing fluid can create fractures and carry proppant in the reservoir, generate heat in situ to avoid cold damage, reduce the viscosity, and improve the fluidity of crude oil. The in situ heat fracturing fluid generates a large amount of inert gas while generating heat, thus forming foam-like fracturing fluid, reducing fluid loss, improving proppant-carrying performance, improving gel-breaking performance, effectively improving crack conductivity, and is clean and environmentally friendly. Based on the improved existing fracturing fluid system, in this paper, a new type of in situ heat fracturing fluid system is proposed, and a system optimization evaluation is conducted through laboratory experiments according to the performance evaluation standard of water-based fracturing fluid. Compared with the traditional in situ heat fracturing fluid system, the fracturing fluid system proposed in this study generates a large amount of inert gas and form foam-like fracturing fluid, reduces fluid loss, enhances the proppant-carrying capacity and gel-breaking performance, improves crack conductivity, the gel without residue and that the gel-breaking liquid is clean and harmless.
