【 摘 要 】

Hydraulic fracturing (HF) is widely used to enhance the production of oil and gas. The accurate evaluation of HF treatments could interpret several parameters, which provides better guidance for HF construction in other wells in the same block. The steeply dipping coal seam has the characteristics of low coal rank, large thickness, large dip angel and good reservoir property. The results of the evaluation are always with diversity and indeterminacy. Therefore, a comprehensive evaluation model is presented on the basis of uncertainty theory and other fracturing evaluation models. The parameters about HF can be obtained by solving this model. This model was applicated on steeply dipping coal seams in Xinjiang, China. The results of fracture geometry showed the validity of this model.
