Description
Technical field
The present invention relates to petroleum gas waste drilling fluids disposal and reuse technology field, specifically relate to a kind of discarded
Drilling fluid separation of solid and liquid evaluation method.
Background technology
Rejected well drilling liquid is stable colloid-suspension system that a kind of grain graininess is little, viscosity is big, and separation of solid and liquid is difficult.
Process rejected well drilling liquid to be primarily intended to improve its solid-liquid separation effect, to reach the harm of reuse and reduction to environment.Comment at present
The method of valency rejected well drilling liquid solid-liquid separation effect is mainly by surveying waste liquid grain diameter, waste liquid fluid loss, waste liquid separation of solid and liquid
The approach such as moisture content of lower floor's mud cake afterwards.
If author is Li Weiping, Shu Fuchang, Xiang Xingjin et al. in 2009 print it is entitled《Chemical industry environmental protection》Periodical on deliver
The paper of one entitled " separation of solid and liquid of discarded saturated salt-water drilling fluid ", it was published on the 4th phase in 2009.It is mainly commented
Valency method is：Discarded using the detached chemically enhanced solid-liquid separation technical finesse Jianghan Oil-field of the de- steady and press filtration machinery of the broken glue of chemistry
Saturated salt-water drilling fluid.This article determines 250mL waste drilling fluids and filters 7.5min under 0.7MPa using mud wavter loss meter
The volume (filter loss, mL) of filtrate afterwards, and calculate water rate;Mud cake after dehydration is dried at (105 soil 2) DEG C, is weighed
Mud cake moisture content is calculated afterwards;Separation of solid and liquid result shows that water rate is up to 68.2% after separation, and mud cake moisture content only has 55.8%.
But these method of testings all have some limitations and not enough.Measure the water yield：Firstly, there are the work of ambient pressure
Separation of solid and liquid is realized with Action of Gravity Field is not fully relied on, institute's dendrometry water yield is bigger than actual separation of solid and liquid gained liquid volume；Its
Secondary, most of clay particle can be sticked on filter paper, and liquid Jing filter paper flows out will pass through the clay particle of suitable thickness, and glue
Soil particle has stronger water imbibition, final to affect the measured water yield.Survey mud cake moisture content：Can only be used as reflection separation of solid and liquid effect
One factor of fruit, can not thoroughly reflect solid-liquid separation effect.May there is following situation：1. mud cake moisture content is high, gives up
Liquid water yield is big.2. mud cake moisture content is little, and waste liquid water yield is little.
The content of the invention
It is contemplated that for defect and deficiency existing for above-mentioned prior art, there is provided a kind of Discarded Drilling Materials solid and liquid point
From evaluation method, compared using the present invention, the survey waste liquid fluid loss with routine, waste liquid grain diameter, mud cake moisture content etc., its survey
Amount result is more accurate, can comprehensively reflect whole separation of solid and liquid process clear liquid and the turbid liquid change of lower floor at the middle and upper levels.
The present invention using following technical proposals by being realized：
A kind of rejected well drilling liquid separation of solid and liquid evaluation method, it is characterised in that analyzed using Turbiscan Lab dispersion stabilizations
Instrument evaluates rejected well drilling liquid solid-liquid separation effect, and step is as follows：
A, take setting volume waste liquid as sample, gel breaker is added in the sample；
B, sample is stirred into 30min；
C, take appropriate amount of sample and be put in multiple Scattering scanning test tube, using Turbiscan Lab dispersion stabilization analyzers, survey
Amount transmitted light and reflection light curve；
D, according to the transmitted light surveyed and reflection light curve, analyze solid-liquid separation effect.
The step c is more particularly：It is 5mm- that c, Turbiscan Lab dispersion stabilizations analyzer arranges sweep limits
75mm, trace interval is set to 40min.
The a steps are more particularly：Take and add gel breaker after 400ml waste liquids stirring 30min.
In the step c, described appropriate amount of sample is 20ml samples.
In described Step d：The transmitted light surveyed and reflection light curve, analysis solid-liquid separation effect is comprised the concrete steps that：
（1）, the turbid liquid solids volume concentration of analysis supernatant liquor and lower floor changes：Supernatant liquor penetrating light intensity increases, and illustrates upper strata
Solids volume concentration diminishes, the turbid liquid intensity of reflected light increase of lower floor, illustrates the solids volume concentration increase of test tube lower floor；
（2）, analysis solid-liquid boundary line position：Penetrating light intensity is solid-liquid point with intensity of reflected light jump present position on curve
Boundary, according to solid-liquid boundary line position liquid content and solid concentration after separation of solid and liquid can be obtained；
（3）, analysis the separation of solid and liquid time：According to surveyed curve, as sweep time increases, when a certain moment transmitted light and reflection
When light curve does not change, now sweep time be the separation of solid and liquid time.
Compared with prior art, what the present invention was reached has the beneficial effect that：
1st, this method evaluates rejected well drilling liquid solid-liquid separation effect using Turbiscan Lab dispersion stabilizations analyzer, and often
The survey waste liquid fluid loss of rule, waste liquid grain diameter, mud cake moisture content etc. are compared more accurately, can comprehensively reflect whole solid-liquid point
Supernatant liquor and the turbid liquid change of lower floor during.
2nd, using the present invention, the change of solid-liquid boundary line position be can intuitively reflect, separation of solid and liquid time, reflected light obtained
With the reflection directly perceived that transmitted intensity is solids volume concentration and particle diameter, accordingly the method evaluation solid-liquid separation effect is more accurate
Really.
