With lower external packer, external packer is opening up on this, lower external packer it is opening down, between the upper and lower external packer
Oil pipe outer rim be fixedly mounted with symmetrically arranged interior packer and lower interior packer, two upper and lower interior packers are oppositely arranged,
A pair of by-pass prots, the upper and lower external packer and upper and lower interior packer are formed with tubing wall between the upper and lower interior packer
Outer rim it is in sealing contact with internal surface of sleeve pipe, certain gap is left between the edge of the upper and lower interior packer, in described sleeve pipe
Portion is provided with multigroup spaced perforation for leading to stratum.
And, the upper and lower external packer is leather cup structure made by elastomeric material, and the upper and lower interior packer is similarly
Leather cup structure made by rubber.
And, bottom in the oil pipe is installed and the steel ball for moving up and down is installed in ball seat, the ball seat, the ball seat it is upper,
Diameter of the diameter of bottom less than steel ball.
And, the bottom of the oil pipe is bell-mouth structure of air.
And, the upper external packer, lower external packer, upper interior packer and lower interior packer are spaced two
It is individual.
And, hydraulic anchor is installed at the oil pipe top.
And, the model PSB-60 type of the ejector pump.
And, the distance between described upper and lower external packer is 30cm.
Advantages of the present invention and good effect are：
1st, water detection device is constituted by the packer of leather cup structure and ejector pump, one time tubing string is completed, not only can water detection but also can
Water blockoff.
2nd, pulling movable tubing string water detection water blocking device rapid alignment stratum well section, facilitates simple and direct, practical.
3rd, the separating surface of water layer, oil reservoir, convenient to operation, raising work can be quickly and accurately found out by this device
Efficiency.
Description of the drawings
Fig. 1 is the sectional view of the present invention；
Fig. 2 is the working state schematic representation of the present invention；
Fig. 3 is water blockoff structure chart of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and by specific embodiment the invention will be further described.
A kind of portable pit shaft dynamic water detection water blocking device, as shown in figure 1, including sleeve pipe 2, oil pipe 1 and ejector pump 3,
Oil pipe is co-axially mounted in described sleeve pipe, the oil pipe internal upper part installs ejector pump, the outer rim middle part of the oil pipe is fixedly mounted with upper and lower interval and sets
The upper external packer 4 put and lower external packer 8, the upper and lower external packer be leather cup structure made by elastomeric material, covering on this
Every the opening up of device, lower external packer it is opening down, the oil pipe outer rim between the upper and lower external packer is fixedly mounted with and is symmetrical arranged
Upper interior packer 5 and lower interior packer 7, the upper and lower interior packer is similarly leather cup structure made by rubber, this two it is upper,
The leather cup opening of packer is oppositely arranged in lower, is formed with a pair of by-pass prots 6 on the tubing wall between the upper and lower interior packer, institute
The outer rim for stating upper and lower external packer and upper and lower interior packer is in sealing contact with internal surface of sleeve pipe, the side of the upper and lower interior packer
Certain gap is left between edge, described sleeve pipe middle part is provided with multigroup spaced perforation 13 for leading to stratum.
In the present embodiment, the bottom in the oil pipe is installed and the steel ball 9 that can be moved up and down is installed in ball seat 10, the ball seat,
The diameter of the upper and lower part of the ball seat prevents steel ball from deviating from less than the diameter of steel ball.
The bottom of the oil pipe is the structure of horn mouth 11, for fish finding top.
The upper external packer, lower external packer, upper interior packer and lower interior packer are spaced two, have
Effect improves sealing property.
Hydraulic anchor 14 is installed at the oil pipe top, and its effect is to fix oil pipe, prevents oil pipe from sliding.
The effect of the steel ball is the sealing property of the lower external packer of detection, because oil pipe is longer and in the process of plug-in-sleeve
In rub always with internal surface of sleeve pipe, if lower external packer is poorly sealed, the possible tubing string is done over again.
The model PSB-60 type of ejector pump.
The distance between upper and lower external packer A is 30cm, and the length at A ends can be adjusted according to practical situation.
The present invention using method be：
Oil pipe is slowly lowered into packer in sleeve pipe and passes through perforation 13, then slowly lifts oil pipe, treats packer A alignedly
After layer, start ejector pump and start working so that negative pressure is produced in oil pipe, when upper external packer 4 and lower external packer 8 alignment perforation
During well section position, then the liquid of jacket exterior is sucked in oil pipe, as shown in Fig. 2 the direction of arrow is the flow direction of liquid in Fig. 2,
The liquid in oil pipe is retracted in ground tanks by ejector pump, staff can conveniently learn be extracted into herein be oil or
Water.
If oil reservoir, lifting oil pipe can be continued up, carry out water detection, paragraph by paragraph test.
The water blockoff flow process of this device is：
Ejector pump pump core is washed out, blocking agent is clamp-oned from oil pipe, by by-pass prot 6, in upper interior packer 5 and lower interior packer
In the presence of 7, pressure-bearing blocking agent is squeezed into bottom water blockoff, and the direction of arrow is water shutoff agent water blockoff direction in Fig. 3.
It is emphasized that embodiment of the present invention is illustrative, rather than it is determinate, therefore present invention bag
The embodiment for being not limited to described in specific embodiment is included, it is every by those skilled in the art's technology according to the present invention scheme
The other embodiment for drawing, also belongs to the scope of protection of the invention.
