Description
Technical field
The utility model relates to technical field of petroleum extraction, specifically test about a kind of easy liquid bridging plug wastage
Device, for testing liquid bridging plug under differential pressure to the wastage on stratum.
Background technique
Gas well liquid loading later period, reservoir pressure coefficient reduce, and directly carry out kill-job using well killing fluid, will lead to well killing fluid to ground
The a large amount of leakages of layer, pollute reservoir;And if insulated using the method for machine plugging to reservoir, after workover treatment, machine
The deblocking reliability and construction period, cost that tool blocks are difficult to bear for low-pressure gas well, also, for realizing septulum
Layer, the closure of same layer perforated interval, machine plugging mode are difficult to carry out.The utility model is it is intended that liquid bridging plug performance provides conveniently
Easy test method.
Summary of the invention
The utility model provides a kind of easy liquid bridging plug wastage test device.
The technical scheme adopted by the utility model is
Test device provided by the utility model mainly includes sealing-plug, and lucite tube, liquid bridging plug, graduation mark is more
Hole medium, free end outlet, high-pressure air source, pressure-regulating valve, pressure gauge, ten parts such as airflow channel.The liquid bridging plug,
Porous media is successively set in the lucite tube, and the graduation mark is arranged on the lucite tube, the freedom
The bottom that the lucite tube is arranged in mouth is brought out, the upper end of the lucite tube, the height is arranged in the sealing-plug
Pressurized air source is connected to by the airflow channel with the inner cavity of lucite tube, and the pressure-regulating valve, pressure gauge are successively set on
The airflow channel uses high-pressure air source as test pressure differential on one end of high-pressure air source, and porous media replaces practically
Layer rock, there is graduation mark can directly read volume wastage.
The brush advantage of the utility model: it is easy to use, it is low in cost, and can be used for other reagents under differential pressure to more
The test of hole media leaks.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of easy liquid bridging plug wastage test device of the utility model.
In figure: 1. sealing-plugs, 2. lucite tubes, 3. liquid bridging plugs, 4. graduation marks, 5. porous medias, 6. freely bring out
Mouthful, 7. high-pressure air sources, 8. pressure-regulating valves, 9. pressure gauges, 10. airflow channels.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1, a kind of easy liquid bridging plug wastage test device of the utility model, device is mainly by sealing
Plug 1, lucite tube 2, liquid bridging plug 3, graduation mark 4, porous media 5, free end outlet 6, high-pressure air source 7, pressure-regulating valve
8, pressure gauge 9, airflow channel 10 forms.Before test, corresponding porous media can be selected to be placed in organic glass according to lithology permeability
There are Anti-fall protrusion in the bottom of glass pipe 2,2 bottom of lucite tube, testing liquid bridge plug 3 are placed in lucite tube 2 later
Inside, adjusts the numerical value that pressure-regulating valve 8 observes pressure gauge 9 after 3 plastic of liquid bridging plug, the numerical value of pressure gauge 9 can approximation recognize
For the pressure difference for being test, after a certain period of time, the numerical value that 3 height change of liquid bridging plug shows as graduation mark 4 in lucite tube 2 becomes
Change, the numerical value change of graduation mark 4 is the wastage of the liquid bridging plug 3 under surveyed time, pressure difference.
