桩西地区Tr,Tg,Tg1,Tg2四个地震反射层上的断裂系统在标度区间0.25-2 km上具有良好的统计自相似性,且由下部反射层到上部反射层分维值大致具有由小变大的规律.在平面上,高值区（〉1.8）主要出现在桩西潜山山头的位置,并具有北西向展布的趋势,低值区（〈1.3）主要出现在规模较大的断层所控制的凹陷地区,分维等值线延伸方向与研究区断裂的走向具有较好的一致性.桩西地区已探明的含油气面积与断裂分维值的分布具有较好的叠合性,可以作为指导油气勘探的一项定量指标.

Fault systems in the seismic reflection horizon Tr,Tg,Tg1,Tg2 are statistically self-similar within the scale range of 0.25 to 2 km,the fractal dimensions of fault systems roughly turns large from bottom to top reflection horizon.On the flat,high fractal dimensions area（1.8） appears in the hilltop zone of the Zhuangxi burried hill and have a northwestern distribution,while low fractal dimensions area（1.3）appears in the sag area controlled by the large scale faults,and the extension direction of the fractal dimension isoline have good coherence with the trend of the fault in study area.There are good superposition between the proved oil and gas acreage in Zhuangxi area and the distribution of the fractal dimension,and the fractal dimension can be a good quantitative index for the guide of the oil-gas exploration.
