Characteristics of fracture and 3D fracture network Simulation of BS03
Fractures investigation of outcrops with the area of 1km 1km around borehole BS03 located at Jiujing section in Beishan area, Gansu province, has been conducted by using window statistic method. Fractures statistic characterization has been studied. It has been shown from the results of statistic that four sets of fractures are dominant in the studied area and orientation of each set is well fitted by Fisher distribution; Trace length of each set of fracture is fitted by log-normal distribution and distribution of fracture aperture is fitted by inverse exponent function. Fracture numbers in unit area, P21 has linear correlation with fracture length in unit area P20, P21=1.36P20. Modeling of 3D fracture network in the studied area has been carried out by using the software Fracman. The analysis of influence of fracture trace length and intensity of fractures on migration pathway of nuclide has been done.
