Based on a large number of geological and geophysical data, the formation, fracture-caves types and hydrocarbon distribution of hoodoo-upland on the Ordovician karst slope in the Tahe area, Tarim Basin, are discussed by analyzing faults and strata thickness. The hoodoo-upland was made of high peaks and narrow valleys in the Ordovician karst slope during the Early Hercynian karst period, which were distributed along the NNE positive flower structure and had inherited evolution. The fault-fractures and fracture-vugs complex were extremely developed, with a thickness of 100 m. The cumulative oil production of 60% oil wells was more than 20×10⁴ t per well in the hoodoo-upland, where the residual thickness of the Ordovician Yingshan Formation was greater than karst depressions. Caves formed by the shelter of collapsed breccias were developed in the valleys. They were 1.6 to 13.5 m high, with a filling rate of 51.6%. The positive flower structure under the settings of strike-slip compression controlled the early formation of the hoodoo-upland on the karst slope, resulting in the differences of drainage distribution and karstification. Compared with the water-rich karst valley, the hoodoo-upland with lean water suffered weaker karstification, had thicker residual stratum, and was higher in terrain. In rainy season, the meteoric water flew and corrode along the cracks, forming a complex network of fractures and caves. Combined with inherited uplift and the effective match of the NNE deep faults, oil and gas continuously charged into the reservoir space in the upland, forming the hoodoo fracture-cave reservoir with vertically quasi continuous distribution, high hydrocarbon abundance and high production.

根据大量的地质和地球物理资料，通过分析断层和地层厚度，探讨了塔里木盆地塔河地区奥陶系喀斯特斜坡上不祥山地的形成，裂缝洞穴类型和油气分布。顶峰高地由海西早期岩溶时期奥陶系岩溶斜坡上的高峰和狭窄谷组成，沿NNE正花结构分布并继承了演化。断层和缝隙复合体非常发育，厚度为100 m。60％油井的累计产油量超过20×10 ⁴在不祥山地上每口井的平均开采量，奥陶系营山组的剩余厚度大于喀斯特洼地。山谷中形成了由坍塌角砾岩遮盖物形成的洞穴。它们高1.6至13.5 m，填充率为51.6％。走滑压缩作用下的正花结构控制了喀斯特斜坡上不祥山地的早期形成，从而导致了排水分布和喀斯特地貌的差异。与富水的喀斯特山谷相比，用稀水灌溉的石林高地的喀斯特地貌较弱，残留地层较厚，地势较高。在雨季，陨石水沿着裂缝飞舞并腐蚀，形成了复杂的裂缝和洞穴网络。
