Annotation:
The scientific articles of domestic and foreign researchers devoted to laboratory experiments on studying the combined effect of water injection of various chemical composition and stresses on carbonate reservoirs are considered. Some of the most important experimental results, reflecting variations in porosity and permeability under the influence of mechanical-chemical effects are presented. It is noted that injected water can cause an intense change in the permeability of carbonate rocks, especially fractured ones, which should lead to a change in the indicators of such types of reservoirs development, in particular, to a change in the injection wells injective capacity
