Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
1,2 first kind of embodiment of the present utility model described in conjunction with the accompanying drawings.
Beam front axle valve under a kind of producing well, comprise valve body (1) and urceolus (2), urceolus (2) is sleeved on the upper end of valve body (1), the last lower inner cavity (3) (4) of valve body (1) does not connect mutually, and valve body (1) radially is being shaped on groove shape formation fluid runner (5), press bypass bridge-type runner (6) in axially being shaped on, groove shape formation fluid runner (5) connects with last inner chamber (3), interior bypass bridge-type runner (6) upper end and the inner chamber of urceolus (2) of pressing connects, the lower inner cavity (4) of lower end and valve body (1) connects, valve seat (7) is arranged in the inner chamber (3), be equipped with ball sealer (8) on the valve seat (7), valve gap (9) spinning goes up the end of inner chamber (3) at valve body (1), ball sealer (8) trap on valve seat (7), is shaped on filter opening (11) on the filter ruffle (10), and is sleeved on the valve body (1), and be positioned at groove shape formation fluid runner (5) and locate, and and the outer wall of valve body (1) between keep certain clearance.Groove shape formation fluid runner (5) is two, and left and right side respectively has one.In press bypass bridge-type runner (6) to have six, forward and backward side respectively has three and all arrange.Be shaped on flowing hole (12) on the valve gap (9).
During use, can be according to the oil field arts demand, this valve can be loaded on the top of single-stage packer, also can be loaded on the top of secondary packer, goes into the well with tubing string.When needs are tested when sealing up portion's pressure packer, get final product from the tubing string pressurization.When needs set bottom pressure packer, build the pressure from the tubing string pitching, set bottom pressure packer.
Operating principle: pressurization can directly set voltage-controlled production packer by interior pressure bypass flow channel in the tubing string, and form positiver sealing by ball sealer simultaneously, the formation fluid passage is disconnected, thereby it is isolated with the stratum effectively, effect owing to formation fluid pressure during oil recovery is appeared on the stage ball sealer, thereby uniaxially layer fluid runner can be provided.
