Specific embodiment
The utility model is further detailed with reference to the accompanying drawings and detailed description.
By taking certain well as an example, its bailing test includes altogether three parts：Mixed pumping test, top, the layering of bottom water-bearing layer are taken out
Water test.Mixed pumping water need not carry out sealing sealing, but upper and lower water-bearing layer bailing test, need to carry out strictly stopping temporarily up and down
Water installations, for closing sealing to be carried out in well casing to different water cut stratum in same wellhole, prevent upper and lower water-bearing layer from ganging up, and rise
To upper and lower water-bearing layer effect is isolated, it is convenient for being layered bailing test.
The structure of this device is illustrated below in conjunction with the accompanying drawings and how to realize being layered bailing test using the utility model.
Referring to accompanying drawing 1, the utility model is including the sealing bed of material 9 being arranged at well casing reducing, located at sealing bed of material top
Upper platen 10, the thrust platen 5 for being connected to the bottom of the sealing bed of material 9 and the weight linear meter 8 being arranged on the sealing bed of material 9 and ventilation
Sighting tube 12, the upper end of the weight linear meter 8 is stretched through after the sealing bed of material 9, upper platen 10, and the lower end of weight linear meter 8 passes through thrust pressure
Stretch after disk 5, the bottom of the weight linear meter 8 is provided with the guide-localization wing 6（When bottom water-bearing layer is drawn water needs sealing, it is oriented to
Location wing 6 may be installed on the pump line of immersible pump 3, and the effect of pump line can replace weight linear meter）, the upper end of the weight linear meter 8 is provided with drop handle
11（Also it is anti-Threaded Connector Coupling）, the upper platen 10, the sealing bed of material 9 and the correspondence position of thrust platen 5 are provided with for wearing immersible pump
The via of pump line, cable and weight linear meter.The sealing bed of material 9 is followed successively by from top to bottom upper film pad, the fried dough twist being fixed together
The sea-tangle of pigtail and/or expanded rubber band, lower Rubber washer.When using, weight linear meter 8 uses a diameter of Φ 75mm's of 6m length
Round steel, ventilation sighting tube 12 adopts 1.2 inches of galvanized pipes, and other specifications can be adopted certainly, and according to actual conditions, satisfaction is used will
Ask.
Sealing is carried out when being respectively used to draw water upper and lower water-bearing layer using this layering antipriming.
1st, sealing when top water-bearing layer is drawn water
For carrying out sealing during bailing test to upper water, isolate bottom water-bearing layer.
When using, upper platen 10 fills separately below two panels Rubber washer（Made with conveyer belt）, sea-tangle is soaked after drying, compile
Fried dough twist pigtail into suitable size is wrapped in below rubber cushion, and outside plastics are wrapped up, and are finally tightened with iron wire, form the sealing bed of material
9.Then it is transferred to into sealing position with steel wire rope or drilling rod（At well casing reducing）, upper platen 10 will under the effect of weight linear meter 8
Sealing material is pushed, and bottom thrust platen 5 is connected to the lower section of the sealing bed of material 9, and bottom thrust platen 5 plays thrusting action, jointly
Sealing material is compressed, sealing material water-swellable, so as to reach the upper and lower water-bearing layer of segmentation, closing sealing purpose.
2nd, sealing when bottom water-bearing layer is drawn water
Sealing during for drawing water to bottom water-bearing layer, isolates top water-bearing layer.Antipriming is needed and drawn water when bottom is drawn water
Equipment combines, together G.I.H, reaches sealing, purpose of drawing water.
Upper platen 10 is provided with the via of cable and submersible pump pipe, and is connected with pump line flange.When using, upper platen
10 and pump line connection, below fill two panels Rubber washer（Made with conveyer belt）, sea-tangle is soaked after drying, weave into the winding of fried dough twist pigtail
Below Rubber washer, outside plastics are wrapped up, and are finally tightened with iron wire, constitute the sealing bed of material.Sealing position is transferred to afterwards
Put, with the sighting tube 12 that enters to ventilate at present, upper platen 10 pushes sealing material under immersible pump and pump line Action of Gravity Field（The situation
Under can be without weight linear meter, now immersible pump and pump line serve the effect of weight linear meter, and pump line can also play a part of guiding, now
The guide-localization wing also can be without being just installed in if you are using on pump line）, thrust platen 5 plays thrusting action, jointly
Sealing material is compressed, sealing material water-swellable, drawn water purpose so as to reach the upper and lower water-bearing layer of isolation, closing sealing.
At present, it is to obtain different water cut layer hydrogeological parameter in same well, is increasingly required and enters in same well
Row layering sealing, should be improved and be innovated according to well actual conditions to layering antipriming.The utility model can also do as
Lower improvement：
（1）This device is provided in reducing well casing, is directly seated at reducing joint, therefore carries out sealing with footpath well
When, antipriming step back-up ring need to be set in the sealing position of setting, it is ensured that the not upper and lower play of the device, affect bailing test
As a result.
（2）To ensure the effect of sealing, water proof, double-deck water sealing structure of the sea-tangle in combination with expanded rubber may also be employed.
