摘　　要：水力压裂增产技术是目前改善油气层最为有效的方法,压裂施工过程中,压裂液的好坏决定施工的成败。针对水基压裂液体系需要达到的性能要求进行了室内试验研究,通过分析压裂液耐温性能影响因素,对高温压裂液体系配方调试及综合性能评价进行了超高温压裂液体系完善优化研究,完成了耐温达到150℃的地面交联酸酸液体系胶凝剂、交联剂、交联延迟剂主剂等的研制和该酸液体系整体性能评价等全部室内研究工作,研制的地面交联酸酸液体系耐温达到150℃,在170s^(-1)的剪切速率下,剪切60min,粘度保持>50m Pa·s,并进行了现场试验,实验结果证明,能够满足现场施工要求,具有良好的推广应用前景。Hydraulic fracture stimulation technology to improve oil and gas layer is the most effective way, the process of fracturing, the fracturing fluid is good or not determines the success or failure of construction. For wa- ter-based fracturing fluid system need to meet performance requirements were studied interior, through the analysis of fracturing fluid temperature performance factors, high temperature fracturing fluid formulation commissioning and comprehensive performance evaluation of the ultra-high temperature fracturing fluid system perfect optimiza- tion study completed all the indoor temperature reaches 150 ℃ work ground-crosslinked acid fluid system gelling agents, crosslinking agents, crosslinking retarder developed master agent and the acid system overall performance evaluation, development ground-crosslinked acid fluid system temperature reaches 150℃, at a shear rate of 170s^-1 shear 60min, viscosity retention〉 50mPa-s, and a field test, experimental results show that, to meet the construc- tion site requirements, with good promotion prospects.
