Application of Flowing Material Balance Method (FMBM) in Dynamic Reserves Evaluation of Changqing Low Permeability Gas Field

Reserve is the material basis of gas field development,so high efficient and reasonable development of Changqing low permeability gas oilfield must be established on the basic of mastering its dynamic reserve.Accurate reserve calculation and analysis of the gas reservoir or single well relate to objective comprehensive evaluation of gas reservoir,regulation of gas well production and working system,deployment and adjustment of well pattern,so it is the basic of scientific development and a prerequisite for long-term high and stable yield of gas field.
