Abstract: With conventional hydraulic fracturing technique, the proppant-pack conductivity will always be impaired because of fracturing fluid residue, proppant crushing and embedment, fines migration etc. The conventional process flow capacity is difficult to break through the maximum theoretical conductivity without any hurt. This thesis begins with theoretical analysis, the permeability experimental results show that the new technology of impulse-stage fracturing forms open channel whose flow permeability and conductivity of proppant are evenly arranged the 3-8 times and 4-9 times corresponding to the counterpart. Further the key content is described that simulating the sand profile with PT software and forming process of open permeable channels by innovative physical model experiment. The implementation of new process mainly involved the optimization of perforation, fracturing fluid system optimization, impulse-stage fracturing pump program design, adding fiber supporting technology etc. Overall implementation is convenient and reliable. The comparison results of 4 horizontal wells with new technology application and 4 conventional horizontal wells: comparable in the average single section liquid volume, average proppant scale reduction in 21.6%, the average single well test yield increased 42.3%, cumulative production increased 38.4% during 5 months, the average index of stabilized production increased 34.3%. The new technology reached double effect of cut cost and increase production, and has widely application prospect in the Western Sichuan compact sandstone horizontal well.
