Characteristics and distribution of tectonic fracture networks in low permeability conglomerate reservoirs

Natural fractures (particularly those reshaped by multiple tectonic stages) are of paramount importance for the development of tight conglomerate hydrocarbon reservoirs. These fractures not only enhance reservoir pore space but also serve as essential conduits for hydrocarbon migration. Focusing on the Permian Jiamuhe Formation conglomerate reservoirs in the Xiaoguai area of the Junggar Basin, this study integrates structural interpretation, core observation, and well-log evaluation to elucidate the characteristics and vertical distribution of tectonic fractures. A paleotectonic stress field numerical simulation is subsequently employed to predict their planar distribution. Results indicate that the Jiamuhe…
