Description
Technical field
The utility model belongs to petroleum industry physical simulation experiment equipment; Particularly the water plugging and profile controlling physical simulation experiment is used the pressure transducer protective device; The laboratory experiment that is used for the water plugging and profile controlling physical simulation; Pressure transducer in the water plugging and profile controlling physical simulation experiment is formed protection, protection experimental facilities, the convenient use.
Background technology
In the water plugging and profile controlling physical simulating device of petroleum industry; Rock core is to be placed in the airtight baking oven; Pressure transducer and other checkout equipment are fixed together, and the pressure tap on the rock core is distant apart from pressure transducer, between them are to connect through very long pipeline.When the water plugging and profile controlling physical simulation experiment, in rock core, inject crude oil and cross-linking polymer system and carry out simulating oil deposit experiment, crude oil and cross-linking polymer system can flow and can get into inside to the pressure transducer direction along pipeline through pressure tap.After experiment finished, pipeline was oversize on the one hand, and crude oil that the inside is residual and cross-linking polymer system are difficult to clean; The crude oil that gets on the other hand in the pressure transducer can pollute tensimeter, and the result has harmful effect to gauge measurement, simultaneously owing to a lot of pressure transducers are fitted together; Dismounting is inconvenience very, and be difficult to clean cross-linking polymer system wherein, in case remaining cross-linked polymer becomes glue; The easy blocking pressure transducer, and then influence is used and experiment effect next time.
Summary of the invention
The purpose of the utility model provides the water plugging and profile controlling physical simulation experiment and uses the pressure transducer protective device, prevents that pressure transducer is contaminated and stops up convenient experiment, protection pressure transducer.
The technical scheme of the utility model is: the water plugging and profile controlling physical simulation experiment comprises pressure-transmission tube, nitrogen supply (NS) bottle, liquid pressure transmission pipeline, the gentle body supply line of gas pressure transmission pipeline with the pressure transducer protective device; On liquid pressure transmission pipeline, the experiment operation valve is housed, on gas pressure transmission pipeline, the pressure transducer protective valve is housed; Liquid pressure transmission pipeline one end is connected with the pressure tap of rock core, and the other end is connected with pressure-transmission tube; Gas pressure transmission pipeline one end connects pressure-transmission tube, and the other end connects pressure transducer; On gas feedthroughs, be provided with vent valve and steam supply valve, gas feedthroughs one end is connected with the nitrogen supply (NS) bottle, and the pipeline between vent valve and the steam supply valve is communicated with gas pressure transmission pipeline.
Compared with prior art the beneficial effect of the utility model is: this protective device effectively prevents the fluid input pressure sensor in the rock core through two kinds of pressure transmission modes of liquids and gases, has effectively shortened the length of liquid pressure transmission pipeline.Its dependable performance, security of operation, simple to operate, easy to use, but the cleaning of dispense pressure sensor gas pressure transmission pipeline.Can be widely used in the water plugging and profile controlling physical simulation experiment, the pressure transducer in the protection experimental provision is without prejudice, and guarantees the accurate of experimental data, reduces experimental cost.

Fig. 1 is the fundamental diagram of the utility model.
Embodiment
Below in conjunction with embodiment the utility model is detailed; Referring to Fig. 1; The water plugging and profile controlling physical simulation experiment comprises pressure-transmission tube 4, nitrogen supply (NS) bottle 7, liquid pressure transmission pipeline, the gentle body supply line of gas pressure transmission pipeline with the pressure transducer protective device; Experiment operation valve 2 is housed on liquid pressure transmission pipeline, on gas pressure transmission pipeline, pressure transducer protective valve 8 is housed; Liquid pressure transmission pipeline one end
WithThe pressure tap of rock core 1 connects, and the other end is connected with pressure-transmission tube 4; Gas pressure transmission pipeline one end connects pressure-transmission tube 4, and the other end connects pressure transducer 9; On gas feedthroughs, be provided with vent valve 5 and steam supply valve 6, gas feedthroughs one end is connected with nitrogen supply (NS) bottle 7, and the pipeline between vent valve 5 and the steam supply valve 6 is communicated with gas pressure transmission pipeline.Pressure cap 3 is installed on the top of pressure-transmission tube 4, and gas pressure transmission pipeline is a way of transparent lines, convenient behaviour in service of observing gas pressure transmission pipeline.
During experiment, pressure cap 3 and 4 of pressure-transmission tubes are tightened, kept pressure-transmission tube 4 vertically to place, can not tilt.Close experiment operation valve 2 and vent valve 5, open pressure transducer protective valve 8.In order to make the quick build-up pressure balance of ability in the pressure-transmission tube 4; Open steam supply valve 6; Nitrogen in the nitrogen supply (NS) bottle 7 is injected pressure-transmission tube 4; Make that gas reaches certain pressure in the pressure-transmission tube 4, the big I of pressure records through pressure transducer 9, and the nitrogen pressure in the pressure-transmission tube 4 is more smaller than pressure tap pressure.Close the steam supply valve 6 of nitrogen supply (NS) bottle 7; Open experiment operation valve 2; Because the pressure of the gas in the physical simulating device in the pressure ratio pressure-transmission tube 4 of rock core 1 pressure tap is bigger, so just has fluid to flow out from pressure tap, get in the pressure-transmission tube 4 along liquid pressure transmission pipeline; Fluid drop drops on the bottom of pressure-transmission tube 4 under the effect of gravity, can not flow to pressure transducer 9.Because fluid constantly gets in the pressure-transmission tube 4, fluid occupies the space of pressure-transmission tube 4, and the nitrogen in the pressure-transmission tube 4 will be by continuous compression.When the pressure of rock core 1 pressure tap and the pressure equilibrium in the pressure-transmission tube 4; The pressure tap place of rock core 1 does not just have fluid and flows out in liquid pressure transmission pipeline entering pressure-transmission tube 4, and at this moment the pressure tap place pressure of rock core 1 is consistent with pressure transducer 9 measured pressure.If rock core 1 pressure tap place pressure increases, just there is fluid to flow out from rock core 1 pressure tap, get in the pressure-transmission tube 4 along liquid pressure transmission pipeline, rebulid new pressure equilibrium, new pressure is that pressure transducer 9 is measured.In rock core 1, injecting flow liquid processes such as crude oil, cross-linking polymer system like this, pressure changes can both be measured by pressure transducer 9.Because the fluid that flow out at rock core 1 pressure tap place does not touch pressure transducer 9, thereby pressure transducer 9 can be not contaminated, there is not the blocked possibility of pressure transducer 9 yet, pressure transducer 9 is effectively protected.There is fluid to get in the transparent gas pressure transmission pipeline as finding in the experiment, should closes experiment operation valve 2 and pressure transducer protective valve 8 immediately.Turn on pressure cap 3, outwell the fluid in the pressure-transmission tube 4, install again after checking, continue experiment.When experiment finishes, turn off experiment operation valve 2 earlier, slowly open vent valve 5,, turn on pressure cap 3 then, clean pressure-transmission tube 4 parts such as grade, got ready and time used again pressure-transmission tube 4 pressure releases.
