The utility model relates to an electric submersible pump well tubular column and an electric submersible pump well. The electric submersible pump well tubular column comprises a Y-shaped connector, an electric submersible pump unit and a testing blocker, wherein the electric submersible pump unit is connected with a lower interface of the Y-shaped connector through a first oil pipe, the testing blocker is connected with another lower interface of the Y-shaped connector through a second oil pipe, the testing blocker comprises a cylindrical valve sleeve and a rod-shaped valve core, the lower end of the valve sleeve is closed, the upper end of the valve sleeve is opened, the valve rod is inserted into the valve sleeve, the upper end of the valve sleeve is connected with the lower end of the second oil pipe, a pressure transferring hole running through the side wall is formed on the side wall of the valve sleeve, a pressure transferring passage is arranged in the valve core, an upper port of the pressure transferring passage can be communicated with a pressure gauge, and the valve core can slide up and down in the valve sleeve, so that the lower port of the pressure transferring passage is communicated with the pressure gauge or sealed by the side wall of the valve sleeve. By adopting the technical scheme, the flow pressure adjacent to the reservoir can be tested without stopping the pump, and the economic benefit is good.
