| 摘 要： | 应用分形理论，对塔里木盆地北部轮南地区奥陶系断裂及储集层裂缝进行研究，结果表明，该区的断裂及储集层裂缝分布均具分形结构，自相关性很好，其相关系数均大于０９９进一步研究表明，平面上的断裂发育区和井下的储集层裂缝发育带是对应的。在碳酸盐岩中找油，储集条件是关键。因此，要彻底弄清轮南奥陶系含油性，应从储集层条件最好的地方入手。分形研究证明，整个轮南地区储集层最好的是平台西区，这应成为近期油气勘探的首选区块。

| Abstract: | By applying fractal theory to study Ordovician fault and reservoir fracture in Lunnan area in northern Tarim basin, it is shown that the distribution of fault and reservoir fracture in study area is of fractal structure and strong autocorrelation (correlation coefficient more than 0.99). Further study showed that the fault distribution trend in plane corresponds to fracture developed belt of reservoir. Reservoir is the key to explore oil in carbonate rock. In order to clarify hydrocarbon potential of Ordovician in Lunnan area, we should start to operate in the district with best reservoir quality. Fractal study showed that the west platform has the best reservoir quality in Lunnan area, and therefore is the first block of oil and gas exploration. |
