The characteristics of hydraulic fracture morphology in glutenite reservoirs: An experimental investigation

摘要: Hydraulic fracturing efficiently unlocks the vast energy potential of glutenite, a crucial unconventional tight oil/gas reservoir. However, the characteristics of the hydraulic fracture (HF) morphology is complex and remains unclear in highly heterogeneous glutenite reservoirs. It is challenging to design fracturing schemes effectively. In this work, rock mechanics experiments and ten groups of true triaxial hydraulic fracturing experiments were carried out to investigate the HF morphology. Critical factors such as horizontal stress difference (HSD), injection …
