Enter injection process, formation material flow process, the extraction of recovery well and the process of shaking out of well.
Several cooling passages are embedded in by way of drilling in the side and bottom surface of reaction kettle body, cooling passage is left
It is right symmetrical, it is the property of the good conductor of heat using metal, so that reaction kettle is integrally reached constant temperature within a short period of time.
The characteristics of using reaction kettle symmetrical configuration, the temperature sensor of asymmetric distribution is set.Temperature sensor is reduced to set
Set the influence for flowing generation in deposition medium to fluid.
Compared with prior art, the utility model has the following beneficial effects:
1) reaction kettle be the overall structure without mechanical interface unit (such as bolt, hinge), reduce under condition of high voltage because
The injection of fluid high-pressure caused by linked set fails is conducive to the safety for ensureing testing crew.Reaction kettle structure is simple, operation stream
Journey is succinct.
2) the different types of sand control screens (such as wrapping wire, slot, steel wool) of setting be can according to need, sand control screens are changed
It makes more convenient.
3) this reaction kettle can also sink in the sum of sand control screens containing hydrate other than it can study the sand controlling result of sand control screens
The particulate matters such as gravel, the sand controlling result of the modes such as research gravel pack are set between product object.
4) there is the access way of fluid at reaction kettle both ends, can not only simulate the process of shaking out that note adopts same well, but also can be with mould
It is quasi- to infuse the process of shaking out for adopting point well.
5) cooling line and temperature sensor dispersed distribution, can by the cooling tube and temperature sensor of different location come
Change and monitor the temperature of different location.
