The optimization of evaluation indez on high abundant CBM enrichment area
The high abundant CBM enrichment areas restrict the principal part of CBM exploration and development, which have an important effect on the growth of reserves and production. Based on principle and methods of CBM system, with coal bed methane exploration technology and actual producing instance, evaluation index structure on high abundant coal bed methane enrichment area is primarily built. Ten index of four sorts index is opted, including thickness of coal seam, gas content, Langmuir volume, permeability, reservoir press, lithology and thickness of top rock, hydrodynamic characteristics, compounding style of draining, gas/water production, well bottom press by using generation, accumulation, preservation and output of coal bed methane. The anatomization, validation and contrast analysis of production CBM well is an important process. On the above mentioned analysis, three class index structure layer is built, which provide for element basts on establishing next more science, more reasonable evaluation index system and Predicting effectively and exactly high abundant coal bed methane enrichment area.
