Abstract

Due to horizontal bedding existence，high horizontal stress difference or no natural fractures in unconventional reservoirs，it¢s difficult to create complex fracture network according to massive hydraulic fracturing. So a new stimulation technology based on high-energy electric impulse was investigated to promote efficient development in above formation. Firstly，an unique electric impulse experimental set-up was innovated under high voltage(25 kV). It could load three principal stresses independently to rock sample，as well as combine electric impulse with hydraulic fracturing in lab. A series of experiments were conducted with large-scale natural shale outcrops(762 mm×762 mm×914 mm) to help study fracture geometry and propagation mechanism. At the same time，more advanced impulse numerical model was established with experimental data. Then the geological and engineering factors effecting on operation distance were analyzed quantitatively. The results showed that the electric impulse could create complex fractures in different directions in shale without casing pipe damage；improving impulse energy could enlarge operation distance obviously，but the number of impulse operation should be designed in a reasonable range；Compared with the traditional hydraulic fracturing，the new operation model of the combination of electric impulse and hydraulic fracturing could be more conducive to create fracture network to improve stimulated reservoir volume. This technology will have good application prospect in oilfield development especially for unconventional reservoir.
