Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
The embodiment of the present invention provides a kind of Injection Well operation oil jacket to divide mobile equilibrium jet-preventing tool, by increasing special oil jacket shunting balance jet-preventing tool on original production cylinder pile foundation, to form under a kind of Injection Well normal pressure handling situations the not outer comb post of overflow in oil pipe, when realizing operation, oil jacket divides the environmental protection operation of mobile equilibrium.
Shown in Fig. 1-5, this Injection Well operation oil jacket divides mobile equilibrium jet-preventing tool specifically to comprise: comprise oil jacket current divider and diverting means bruising and block up,
Described oil jacket current divider comprises top connection 1, outer adapter sleeve 2, first Clip Reed 3, slip diversion sleeve 4, fixing pin 6 and lower contact 7; Wherein, O RunddichtringO 5 is provided with between outer adapter sleeve 2 and slip diversion sleeve 4.
