The invention provides a hierarchical pouring polymer tube column which can avoid blocking and difficult cast. The tube column includes the out pouring oil tube and the inner pouring oil tube set in the out pouring oil tube, the inner/outer flow passage connected to the different oil layer in the inner pouring ploy oil tube and between the inner and out tube. The top of the inner and outer flow passage are connected with the pump station by the pouring polymer controlling device. The inner flow passage is connected with the oil layer by the closed interpolator and the outer flow passage is connected with the oil layer by the big duct sieve vessel. The pouring control device is the low sheared valve. The invention can be used in the hierarchical pouring oil extraction production.
