Keywords: studies of clay fraction mineralogical composition, change of injected water salinity, oil recovery
Annotation:
The article presents the results of studying the mineralogical composition of rock samples clay fraction, the various waters injection in the fields of the Western Siberia and analyzes the operation of wells. It has been determined that clay minerals swelling significantly affect the ultimate oil recovery of reservoirs while maintaining reservoir pressure by water injection.
