R/S分形预测裂缝发育程度

裂缝发育与否对于低渗低丰度气藏有着至关重要的影响，根据分析本区块不同岩性的成像测井对应层位的裂缝参数以及自然伽马分维数，建立二者之间的联系，形成了一套通过自然伽马分维数来识别不同岩性裂缝发育程度的图版，本区块裂缝孔隙度的范围在0-0.15%之间，以0.05%，0.1%为裂缝发育程度的界限，分为发育，较发育，不发育3类，进而预测裂缝发育的程度。

The development of fracture has a crucial impact for low permeability and low-abundance gas reservoir, according to the analysis of fracture parameters of the imaging logging blocks of different lithologies and natural gamma fractal dimension, established links between them to identify the formation of a different lithologies fracture development through natural gamma fractal dimension chart, the scope of the block fracture porosity between 0 to 0.15%, 0.05%, 0.1%are fracture degree boundaries, divided into development, Comparative development , not developed three categories, and then predict the degree of fracture development.
