Abstract:

The development of fractures under the influence of faults is an important aspect of quantitative study of structural fractures in the carbonate rock area, which is important to reservoir prediction of fractured carbonate oil and gas reservoir. In order to know the development and distribution of structural fractures around the thrust faults, this paper studies the surface density and fractals with the example of Tazhong No.1 Fault. An exponential relationship between structural fracture surface density and its distance to the fault is discovered in this research, and the controlling width is about 3000 m; besides, in this paper we divide the development of structural fractures into three levels on the basis of fractals, with high fractals near the fault and low fractals far from the fault; making the description of fracture development quantitative.

Key words:  Tazhong No.1 Fault, structural fracture, fracture density, fractals
