在克拉2气田井点裂缝准确识别的基础上，建立断层分维值与裂缝密度之间的关系，并使用前者为约束，对裂缝的井间分布进行预测。研究结果表明，研究区裂缝以构造成因为主．多数为半充填高角度缝，开度0．1～0．4mm，线密度0．142～1．842条／m；井点断层分维值与测井解释的裂缝线密度正相关，分维值可以衡量裂缝发育程度；研究区内分维值大于1．2的区域有利于裂缝的发育，分维值大于1．25的区域裂缝最发育。%Based on the accurale recognition of fractures in well point of Kela-2 gas field, this paper estahhshed the relationship between the fraetal dimension of fault and Ihe fracture density, and predieted the fracture distribution between wells by the fractal dimension of fault. The study results indicate that (1) the fractures in this area are dominated by structural fracture, with most half-filled and high-angle ones, and the fi'acture aperture ranges fror 0.1 mm to 0.4 ram, and linear density from 0.142 n/m to 1.842 n/m: (2) the fractal dimension of fault in well point can be used to predict the degree of fracture development, for it is of positive correlation with linear density of frature in- terpreted from well logging data; (3) the area with fractal dimension value bigger than 1.2 is favorable to the generatinn of fractures, and in area with that higger than 1.25. fracture is most developed
