Study on Horizontal Well Fracture in Low Permeability Reservoirs

Abstract:

In the low permeability reservoirs development process, some times horizontal well is not meet the anticipant production for low vertical permeability or serious reservoir damage, so the horizontal well fracture is needed to improve production rate, several fractures would be created along the length of horizontal well to get the more production rate and ultimate recovery. The fracture shapes was introduced, the principle, characteristics and treatment steps of different Multi-interval fracturing technique was analyzed such as chemical isolation, mechanical isolation, hydraulic sand blast, and limited entry fracturing technology, the feature of limited entry treatment and staged fracturing treatment were discussed for providing some suggestion to field fracturing technology choosing.
