Embodiment Construction
[0014] see Figure 1-7 , the present invention is a layered injection choke for chemical flooding, which is composed of an upper joint 1 and a choke core 2, wherein the upper joint 1 and the choke core 2 are threaded and installed in a chemical flooding injection device (existing Technology) in the offset hole 3, cooperate with the smooth inner surface of the offset hole 3 to form a labyrinth flow channel 26.
[0015] The choke core 2 is composed of an inlet end 25, a center column 22, a left stopper 23, a right stopper 24 and an outlet end 21 arranged on the same axis, and the top and bottom ends of the center column 22 are respectively connected with cross-sectional shapes Outlet port 21 and inlet port 25 are waist-shaped. A plurality of left stoppers 23 and right stoppers 24 are equidistantly connected to the central column 22 between the inlet end 25 and the outlet end 21 . The left block 23 and the right block 24 are in the shape of a circular plate with a small half cu...
