Abstract The adaptability and the effect of simultaneous hydraulic fracturing in sandstone reservoirs of ultra-low permeability was investigated in the field tests in two adjacent horizontal wells,Yangping-1 and Yangping-2, located in Longdong area,Changqing oilfield,China. The simultaneous fracturing treatment was performed in the two testing wells. Micro-seismic monitoring analysis of fracture propagation during the stimulation treatment indicates that hydraulic fractures present a pattern of complicated network expansion. The test data after fracturing show that the daily production of the well Yangping-1 and the well Yangping-2 reaches 132.3 and 109.5 m3/d respectively,which are approximately 9.4 times and 7.8 times the daily production of a fractured vertical well in the same area. It is also shown that the simultaneous hydraulic fracturing of two adjacent horizontal wells enlarge the expansion area of hydraulic fractures to obtain a larger drainage area and to realize the full stimulation of ultra-low permeability sandstone reservoirs in Changqing oilfield.
