The invention relates to a method for increasing the yield of an oil gas well by controlling water pressing crack, in particular to water control pressing crack technology which takes a jelly glue system capable of automatically reducing the viscosity when encountering bottom water as a pressing crack liquid and wax-coated sand as partial supporting agent. At present, when hydraulic pressing construction is performed on low permeating bottom water oil pool, because the stress difference between layers is small or no interlayer forms the stress difference between the layers, the extending of cracks in the vertical direction can be effectively prevented, cracks formed by the hydraulic pressing crack extend and enter a water layer on the bottom in the vertical direction and jump to flow into a shaft along the cracks, and violent flooding of an oil well is generated.
