Embodiment Construction
[0042] exist Figure 1 ~ 3 In the middle, the elastic bump step-by-step axial extrusion throttle is composed of a ferrous locking body 1, a throttling body 2, a double sealing capsule 3, an elastic booster 4, and a tapered glower 5. The throttle device achieves the downhole rapid sitting and salvage by the kaisher locking body 1, complete the sealing and unsapping of the seat by the double sealing rubber 3 and the elastic booster 4, and combined with the tapered throttle 5 and the throttle body 2 form a stable throttle field to effectively solve the routine gas well and the well-defined problem of well-defined wells, and prevent the natural gas hydrate from the underlying process.
[0043] exist Figure 1 ~ 3 In the middle, the elastic bump step-by-step axial squeezing the throttling device is fixed to the tube wall of the tube post, and the boosted matrix of the elastic booster 4 Connect with the downhole screen, the kaisha locking body 1, the throttle body 2 and the elastic booste...
