Aqueous solution is displacing medium, to increase the viscosity of injection water, improves its sweep efficiency, thus reaching the mesh improving oil recovery factor
, and the polymer solution viscosity prepared is higher, its sweep area is bigger, and oil displacement efficiency is also more preferable.
Polymer solution viscosity is a leading indicator of impact oil displacement efficiency, when polymer solution mixture, or passes through
In the course of conveying of pump and gate, or when being injected by perforation holes, or the stratum near wellbore, and ooze in whole oil reservoir
During stream, high stress all may be subject to degrade.In ground injecting system, the mensure of powdery polymer degraded
The sample being taken using curing tank as standard sample, at steady state, respectively to curing tank, low sheraing screw pump, coarse filter,
Fine filtrator, storage tank, high-pressure metering pump, static mixer and injection well wellhead sampling, generally with injection well wellhead sampling and mark
Quasi- sample solution viscosity contrast, to evaluate the impact to oil displacement efficiency for the polymer solution viscosity loss.
Connected with needle valve at the sampler being usually used at present, or the feed liquor being connected with shaft collar, feed pathway is little,
There is right angle bend, polymer has shearing phenomenon；Sample time is long, easily freezes in winter；There is no current-limiting apparatus, liquor stream during emptying
Shakiness, easily causes pipeline to shake, valve is often slowly automatically switched off, and sample rate is slow after unlatching；Install and need during sampler
Stop note operation, impact is normal to be produced, and wastes time and energy.
Therefore, it is necessary to provide a kind of deep for profile control and water plugging, deep profile correction, polymer flooding and chemical flooding solution to adjust
Drive Wellhead sampler, to overcome drawbacks described above.
Content of the invention
The purpose of the present invention is to be to provide a kind of deep profile correction Wellhead sampler, for profile control and water plugging, deep profile correction,
