Description
Technical field
The present invention relates to mechanical design field, especially a kind of slow-release solid solubility property Lab-evaluation device.
Background technology
Along with the development of oil & gas industry, the slow-release solid class material with slow solubility property is constantly researched and developed and throws
Enter to use, the products such as such as spacetabs type anti-scale rod, slow-release solid are sour.At present, to the Essential Performance Requirements of slow-release solid it is
There is under media flow state good slow-release capability, course of dissolution will not produce solid impurity affect equipment run or
Blocking stratum.
But indoor do not have a kind of experimental evaluation device evaluated its release performance and observe its dissolved state at present.
Summary of the invention
The technical problem to be solved is to provide a kind of release performance that can simulate slow-release solid, again can
Observe the slow-release solid solubility property Lab-evaluation device of its dissolved state.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: a kind of slow-release solid solubility property room
Inner evaluation device, including pass sequentially through connect pipeline be attached liquid pump, effusion meter, heater, pit shaft simulator, point
Analysis sample tap；Liquid pump can regulate injected media speed, and flowmeter survey medium flows through the speed of pit shaft simulator, heater
Firing equipment for temperature-adjustable.
Described liquid pump is the one in plunger displacement pump, screw pump, centrifugal pump.
The heating efficiency of described heater is 0 DEG C-100 DEG C.
Described pit shaft simulator is made up of one or several in rustless steel, plastics, fiberglass, PVA.

Lose.
The invention has the beneficial effects as follows: can the impact on solid rate of release with simulation wellbore hole temperature and water velocity, again
Solid course of dissolution in the wellbore can be observed, can more efficiently evaluate slow-release solid state in the wellbore.
Accompanying drawing explanation
Fig. 1 is the structural representation of the slow-release solid solubility property Lab-evaluation device of the present invention.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, the slow-release solid solubility property Lab-evaluation device of the present invention, including passing sequentially through connection pipeline
The liquid pump 1 that is attached, effusion meter 2, heater 3, pit shaft simulator 4, analytical sampling mouth 6；Liquid pump 1 can regulate injection
Medium velocity, flowmeter survey medium flows through the speed of pit shaft simulator 4, and heater 3 is the firing equipment of temperature-adjustable.
Described liquid pump 1 is the one in plunger displacement pump, screw pump, centrifugal pump.The effect of liquid pump is to inject in pipeline
Fluid, this fluid is probably oily substance and is also likely to be water.
Heater is by the firing equipment of a kind of temperature-adjustable, it is ensured that medium can be heated to design temperature,
Simulation slow-release solid course of dissolution under temperature in wellbore, the heating efficiency of heater is 0 DEG C-100 DEG C.
Described pit shaft simulator 4 is made up of one or several in rustless steel, plastics, fiberglass, PVA.
The material of described pit shaft simulator is opaque material, leaves on pit shaft simulator surface and is easy to observe spacetabs type admittedly
The observation window 5 of body dissolved state in pit shaft simulator.
Described connection pipeline is made up of rustless steel, PVA or plastic material, and pipeline inside diameter ranges is 6mm-50mm.
Described connection pipeline exterior heat-insulation layer wraps up, and reduces medium as far as possible and flows through the heat damage caused in pipeline process
Lose.
There is sample tap in pipeline outlet position, the liquid taken out can be carried out active substance detection in sample tap.
The present invention can either evaluate the ability of slow-release solid release active substance, can observe again its in the wellbore molten
Solution state, makes the laboratory performance evaluation more closing to reality of slow-release solid rod, more convincing.
The using method of this invention: slow-releasing solid, to temperature required, is put into shaft drum form by the temperature of regulation heater
Intend in device.Opening liquid pump and current are modulated suitable flow, the flow injecting water can be detected by effusion meter, slow
The active substance content that the dissolution velocity of the property released solid flows out water by detection is determined；The dissolved state of slow-releasing solid can
To be observed by the observation window on pit shaft simulator.
In sum, present disclosure is not limited in the above embodiments, and the knowledgeable people in same area can
Can propose other embodiment within technological guidance's thought of the present invention easily, but this embodiment is included in this
Within the scope of bright.
