Propagation Mechanism Study of Hydraulic Fracture in Low Permeability Glutenite Reservoir

Abstract:

The frequency of fracturing practice in glutenite reservoir has increased gradually with the progress of exploration and development technology. Glutenite, which has properties like fast transformation in phase, great change in lithology, permeability and dip angle, irregular fracture face, disturbed flow phenomenon, severity in heterogeneity and complex pressure system,explains the low efficiency and success rate of hydraulic fracture's utilization in glutenite reservoir exploration and development. This paper features the glutenite reservoir in Songnan area, using PT software, with data of artificial fracture monitoring and well temperature etc. combined, to deal with construction curve, further explores the artificial fracture propagation mechanism. What's more, effect of in-situ stress on fracture propagation mechanism is determined and the fracturing technical measures in glutenite reservoir is also proposed with acoustic emission Kaiser experiment, both of which can effectively channel fracturing well and layer selection and design optimization, improve efficiency and success rate of hydraulic fracturing.
