Description
Technical field：
The utility model is related to a kind of factor determination instrument, and in particular to a kind of simple, efficient weight method filterable agent is determined
Instrument.
Background technology：
In recent years, the oil such as grand celebration, huge port, triumph and Bohai Sea at home of the chemical flooding Drainage process by representative of polymer flooding
Field is widely used, and achieves good oil increasing precipitation effect.In mining site actual production process, generally first by polymer
Dry powder is dissolved in water and is configured to mother liquor, is then diluted polymer mother liquor according to design concentration, eventually passes multistage filtering
Stratum is injected after PROCESS FOR TREATMENT, displacement of reservoir oil purpose is realized.Therefore, the quality of polymer quality is become in order to which can polymer flooding obtain
One of successful key factor.Therefore, domestic Daqing Oil Field Co., Ltd has formulated and has evaluated the 11 of polymer dry powder performance
Item Testing index, filterable agent is one of them.If filterable agent is not up to standard, stratum is will result in during polymer flooding
Block, in turn result in injection pressure and mainly consume near injection end, so that reducing polymer flooding reservoir employs effect.It is so-called poly-
Compound filterable agent refers to, under 0.2MPa pressure conditions, and the polymer solution in closed container passes through diameter 47mm, aperture
3.0 μm of nuclear pore filter film, record instills the time Δ that liquid volume in collector respectively reaches 100mL, 200mL and 300mL
T100、ΔT200With Δ T300, then filterable agent N is defined as:。
At present, polymer filtration factor determination instrument is broadly divided into three kinds according to device construction and operating principle:（1）Manually
Counting method, is recorded after the time for reaching 100mL, 200mL and 300mL by nucleopore filtrate volume by artificial stopwatch, utilizes meter
Calculate device manual calculation filterable agent；（2）Volumetric method is automated, by being collected in filtrate in graduated cylinder at 100mL, 200mL and 300mL
Level electrode is installed, it is automatic to collect the time that liquid level reaches corresponding position, then calculate filterable agent；（3）Automation
Gravimetric method, is weighed using electronic balance to filtrate, and the time of weight corresponding to 100mL, 200mL and 300mL is recorded respectively,
Then calculate filterable agent.But it was verified that artificial calculating method one side precision is not high, another aspect human input is big, test
Staff is easily tired when time is longer；Although automation volumetric method alleviates manpower burden, but measuring accuracy is by electrode
The scale precision that installation accuracy collects graduated cylinder with filtrate influences, and polymer solution belongs to viscous fluid in addition, so belt electrode is received

The convenient advantage of clean and maintenance, but the fixed-point data collection that the method for testing is used, gathered data are limited, when data are wrong very
Hardly possible finds and is only capable of meeting filterable agent calculating, it is impossible to polymer solution strainability in test process is described, from following analysis
In it can also be seen that the method does not account in filtrate collection level change that the testing time is influenceed.As shown in figure 3, setting balance
Initial range between top collector and reservoir is H, and the floor space of tubular collector is π r2, gravity acceleration g, polymerization
The speed that thing liquid drop leaves reservoir lower end filter membrane is Vo, liquid volume is V into collectorL.Therefore, the liquid of any time
Face is highly L=VL/(πr2), it is V to reach speed when being contacted in collector with liquid levelt（Vt=Vo+gt）, not in the same time drop from
Reservoir outlet end reach collector time be.Due to polymer mistake
What the definition of the filter factor had explicitly pointed out needs measure is the time that respective liquid volume is reached by filter membrane, therefore time t is only
Should be with VoCorrelation, should not be related to collector form r.This is also the shadow that three kinds of methods are not considered on test philosophy
The factor of sound.
