In modern conditions the complexity of conducting the repair work of wells has been steadily increasing. This is due to a significant deterioration of mining and geological conditions of oilfields - decrease of reservoir pressure, deterioration of reservoir properties of productive formations, the infiltration of the formation water, and others. Also, there are still relevant problems associated with conducting the works on wells in terrigenous reservoirs with heterogonous permeability containing clay minerals. In such conditions on the first place arises the question of preservation of reservoir properties of formations during the repair works. This problem can be solved with the use of modern highly effective blocking compositions with condensable solid phase.
