Abstract
The utility model relates to a prevent oil cup of spouting for displacement is pressed in rock core area experiments. Its structure includes bowl cover, cup, valve pocket, valve ball, lower baffle, valve, drain pipe, its characterized in that, bowl cover lid in the cup top, cup middle part have the step, the valve pocket be located step middle part, the valve ball be located inside the valve pocket, lower baffle be located the valve pocket lower part, lower baffle edge porose, can keep space intercommunication about its, the drain pipe be located cup bottom, the valve be located the drain pipe, can control the drain pipe connected state. When spreading into the oil cup into in the pump is followed to the opposite pressure shock wave, the valve ball can prevent pressure to swash wave propagation to oil cup upper portion rapidly, and then reaches the purpose that prevents glass interior liquid ejection.
Description
Technical field
This utility model belongs to Oil-Gas Field Development Engineering field, is specifically related to a kind of rock core displacement test blowout prevention with pressure and goes out lubricating cup.
Background technology
In the indoor assay of current oil and gas development engineering field, carrying out cold store enclosure by displacement test, to measure phase percolation curve be one of important experiment. In the process, it is necessary to oil or water are pumped into rock core by hand pump, completes displacement process.
Use traditional lubricating cup to carry out in displacement process with pressure, when pressure is excessive in pump, after opening the valve below lubricating cup, due to differential pressure action, the liquid in hand pump can be squeezed oil return cup, cause the situation that in lubricating cup, liquid sprays in lubricating cup. Even bowl cover punching can be fallen time serious, make liquid in cup spill, pollute laboratory table and cause the wasting of resources. Current processing mode mainly has two kinds, and one is lengthen lubricating cup void volume, makes the height height less than lubricating cup hollow volume of oil ejection, is unlikely to ejection lubricating cup, but the method needs to dramatically increase lubricating cup height, is unfavorable for the portability of experimental apparatus. Two is transfer at instrument to spread plastic paper, makes greasy dirt drop on plastic paper, but the method is not easy, and greasy dirt still can pollute instrument.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of rock core displacement test blowout prevention with pressure and goes out lubricating cup, and this lubricating cup can effectively suppress the liquid ejection caused by pump chamber to the pressure excitement in cup.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is:
A kind of rock core displacement test blowout prevention with pressure goes out lubricating cup, its structure includes bowl cover, cup, valve pocket, valve ball, lower baffle plate, valve, drain pipe, it is characterized in that, described bowl cover covers above cup, step is had in the middle part of described cup, described valve pocket is positioned in the middle part of step, described valve ball is positioned at inside valve pocket, described lower baffle plate is positioned at valve pocket bottom, described lower baffle plate edge is porose, it is possible to being held on the connection of lower space, described drain pipe is positioned at bottom of cup, described valve is positioned on drain pipe, it is possible to control drain pipe connected state.
Design principle of the present utility model:
In this device, when liquid is normally pumped into, valve ball is affected by gravity and can contact with lower baffle plate, now opens above valve pocket, and oil is flowed downward by lower baffle plate edge. When receiving unexpected opposite direction shock wave, valve pocket can move rapidly upward, blocks above valve pocket, stops pressure shock wave to be delivered to lubricating cup top, thus stoping the oil in lubricating cup to receive pressure shock wave and spray.
The beneficial effects of the utility model:
Be can be seen that by above-mentioned principle design, it is simple that a kind of rock core displacement test with pressure blowout prevention that this utility model provides goes out cup structure of extraction, it is easily maintained, rationally distributed, operating aspect, feasibility is good, practical, can effectively alleviate reciprocal pressure shock wave and be passed up to lubricating cup the first half, it is prevented that in lubricating cup, liquid goes out lubricating cup.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that a kind of rock core displacement test blowout prevention with pressure of this utility model embodiment 1 goes out lubricating cup, in figure: 1 bowl cover, and 2 cups, 3 valve pockets, 4 valve balls, 5 lower baffle plates, 6 valves, 7 drain pipes.
Detailed description of the invention
Embodiment 1
A kind of rock core displacement test blowout prevention with pressure goes out lubricating cup, its structure includes bowl cover 1, cup 2, valve pocket 3, valve ball 4, lower baffle plate 5, valve 6, drain pipe 7, it is characterized in that, described bowl cover 1 covers above cup 2, step is had in the middle part of described cup 2, described valve pocket 3 is positioned in the middle part of step, it is internal that described valve ball 4 is positioned at valve pocket 3, described lower baffle plate 5 is positioned at valve pocket 3 bottom, described lower baffle plate 5 edge is porose, the connection of lower space can be held on, described drain pipe 7 is positioned at bottom cup 2, described valve 6 is positioned on drain pipe 7, drain pipe 7 connected state can be controlled.
The undeclared part related in this utility model is same as the prior art or adopts prior art to be realized.
