The limited entry fracturing technique is considered feasible for treating the thin and lover permeability sandstone interbeded with shale in Daqing Oil-fields, in case that horizontal fractures are induced. 15 to 20 individual sandstone layers can be treated without the need of manipulating the tubing string during one fracturing job with small volumes. Various types of post-fracture tests revealed that 80–90% of the objective formations are stimulated. The key points for limited entry completion fracturing technique lie in the accurate interpretation of watered out thin layers, high resolution, low density perforation, and the use of separated-layer fracturing string.
