Abstract: This paper studies the macro and micro features, types, and distribution patterns of fractures by means of well logging interpretation, core observation, identification and well logging imaging. Based on detailed observation of 8 well with a total length of 55.89 m, we count up the number, occurrence and distribution patterns of fractures in northern Kunlun bedrock reservoir, Qaidam basin. By means of calculating parameter and fitting new logging curve, we identified 247 fractures from basement section of 16 wells. The results show that the reservoir space in the upper residual section is weathering fracture dominating which caused by heterogeneous physical property of different lithology, the thickness is 0 m to 60 m. The medium section under the crust bedrock shows the best reservoir capability, the reservoir space mainly consists of joint fracture and dissolution caves, with a thickness of 40 m to 180 m. Only a few structural fractures occur within the bottom fresh bedrock. Based on evaluation parameters distribution, the fracture frequency and development ratio is controlled by distance to the faults, while the fracture frequency displays insignificant negative correlation with the distance than the fractures frequency which was controlled by variable factors.

Key words: bedrock reservoir, dissolution, fracture development ratio, fracture frequency, Qaidam basin
