Development Countermeasures for Low Pressure and Low Production Wells in Unconsolidated Sandstone Gas Reservoirs

With the development of loose sandstone gas reservoirs,low production and low pressure gas wells have increased gradually,it caused reserves imbalance in gas reservoirs,affected the implementation of development plan,reduced the ultimate gas recovery.To ensure the stable production in the gas field,a typical loose sandstone gas reservoir in Sebei Gas Field was taken as the background of study,on the basis of reservoir characteristics and the analysis of gas well production characteristics,the low production and low pressure gas wells were classified.Then combined with the causes of formation of low pressure and low production wells,the development countermeasures for different types of low production wells are put forward.Field application effect shows that corresponding development countermeasures can improve the gas well production,guarantee stable gas production,improve the ultimate recovery of gas reservoir.
