Fracture Effectiveness Evaluation of Ultra-Deep Tight Sandstone Reservoirs: A Case Study of the Keshen Gas Field, Tarim Basin, West China

Fracture effectiveness evaluation has an important impact on the efficient exploration and development of ultra-deep fractured reservoirs. Based liquid production profile results collected during Keshen gas field based traditional static fracture density, opening filling degree, reservoirs is carried out from perspectives activity, connectivity. The show that characteristics, such as density properties, are only some factors determine fractures. From perspective contributions to reservoir permeability, dynamic parameters connectivity key in determining Practice proven fractures with a high shear ratio, low stress environment connection system around well main seepage channels for oil supply process. research provide scientific basis location deployment, optimization reconstruction intervals schemes.
