То improve the efficiency of squeeze jobs using selective compounds on the basis of waterless cement slurry (WCS) there was developed the соmрlеx technology of selective water shut-off in which а selective composition — hydrocarbon solution of а water-repellent surfactant and (or) inverse emulsion based on it — is injected before the WSC, depending on the well injectivity. In the process of injection waterproofing composition occurs the destruction of the water fi1m, squeezing out water from the bottom zone. The hydrophobic agent is attached to the rock surface, preventing its resaturation. High selective and isolating properties of the given соmрlех technology of selective water shut-off by the ехаmрlе of the oilfields of the Western Siberia and Turkmenistan are confirmed.
