In order to improve the production of Gulong shale oil from well stimulation, a Geoengineering integrated model was established through integration of geological modeling, geomechanics modeling, fracturing modeling and reservoir simulation from QH working pad in Daqing oilfield, Northeast China. Based on integrated modeling workflow and study, key stimulation parameters such as stage interval, clusters of stage, frac liquid volume and proppant volume, well spacing were quantitatively optimized. Optimization study indicated 70-80m stage interval, 10m cluster interval (7 clusters per stage), frac volume 1,400 m3 per stage, proppant volume 140 m3 per stage are best parameters in QH pad and 400 m well spacing staggering across zones are best well pattern to QH pad. The study results are of great significance to the realization of large-scale rapid production increase and profitable development for Gulong shale oil reservoirs.
