摘要
The Ordovician Yijianfang Formation in the S108 area of the Tahe Oil Field of the Tarim Basin is carbonate fracture reservoir. Based on drilling, logging, core description, FMI and well log, fractures have been identified. The fractures in the area include structural, dissolution and subtractive original ones,among which the structural ones constitute the main portion of fracture network. Fracture evolution has experienced 3 stages: the Early Hercynian, the Late Hercynian,and the Indosinian-Yanshanian.The most important stage is the Late Hercynian. Thanks to 3-dimensional seismic data, with amplitude change rate, coherent body analysis and impedance inversion technique,fracture zone of the Yijianfang Formation in the S108 area has been predicted.
