The invention discloses a hydraulic ejecting and squeezing type plugging device and relates to a sealed plugging device for oil stolen valve blocking and removing of oil and gas transmission pipelines. The problems of leakage and non-tight high pressure sealing of an existing wooden wedge during plugging are mainly solved. The hydraulic ejecting and squeezing type plugging device relates to the problem of a header of a cylindrical body. According to the hydraulic ejecting and squeezing type plugging device, one end of a connecting ring is installed at the top of the header of the cylindrical body, and a hydraulic cylinder is connected to the other end of the connecting ring; one end of an ejecting rod installed in a hydraulic cylinder body penetrates through the connecting ring to be connected with a pressure head or a hole measuring head, a polyurethane plug head is connected to the pressure head, and a ruler rod is installed at the other end of the ejecting rod. A polyurethane bar is squeezed into an oil stolen hole through a hydraulic mode for realizing the function of oil stolen valve removing with zero pollution and zero leakage. By means of the hydraulic ejecting and squeezing type plugging device, not only is the plugging process which is safe, reliable and free of pollution achieved, but also pressure plugging of a high pressure pipeline is achieved, and the impact of oil stolen hole removing and maintaining on oil and gas pipeline normal production can be eliminated.
