Zhongyuan Oilfield is featured by low gas reservoir pressure, long perforation distance and bad well condition of some wells. Rimming at setting these problems and realizing effective development of the reservoir, research work on enhancing recovery techniques suitable for the reservoir condition was carried out. The optimized fracturing design parameters and operation methods, along with the propping agent slug and the optimal perforation techniques, greatly improved the accuracy rate of fracturing parameters design, the successful operation ratio, and the fracturing effects. By optimizing the low damage fracturing fluid adaptable for different kinds of gas reservoir and adopting techniques such as comprehensive protection, segregated gel breaking and hard closing of fractures in operation, the reservoir damage by the fluid was extremely decreased.
