摘要
The main controlling factors of coal-bed gas reservoir formation include right pressure system, right transit system and corresponding energy mechanism,which is the space-time configuring relation of effective pressure system and effective transit system of coal-bed gas reservoir substantively. Flexibility energies of coal-bed gas reservoir are just about ties between the two systems. Different flexibility energy models are put forward in this paper, three-unit differentiate symbols of coal-bed gas reservoir formation function are established, and their distributing laws in Qinshui Basin are discussed. The results considered that there are 27 sorts of styles of coal-bed gas reservoir formation function, but just 8 sorts are propitious for coal-bed gas enrichment and high produce. Actually only 2 favorable styles in Qinshui Basin are effective pressure system and effective transit system distributing in Daning-Panzhuang-Fanzhuang zone of southern basin.
