ABSTRACT:
The invention relates to oil production stimulation methods and can be used for both reservoirs with fractures resulting from the fracturing procedure and reservoirs with naturally occurring fractures, for which the fracturing procedure is not mandatory. A material which expands while hardening or setting, is injected into the near-wellbore region of a cased well, into the space between the casing and the reservoir, and the wellbore is then perforated. A material having an expansion degree sufficient for application of pressure to the wellbore walls and for keeping at least one fracture open is used as the material which expands while hardening or setting. After the perforation has been done, the reservoir is hydraulically fractured. For naturally fractured reservoirs, the fracturing procedure is not mandatory.
