Description
Technical field
The present invention relates to oil and gas exploration technical field, specifically a kind of oil and gas exploration laboratory tank
Dress sample collector.
Background technology
In oil-gas exploration, identification and the evaluation of oil-gas-water layer are one of important steps in oil-gas exploration and development work,
The application of well logging new technology has caused the attention of increasing expert and scholar both at home and abroad at present.In recent years, as oil field is surveyed
That visits progressively gos deep into, and the object of resource exploration is more diversified, and including shale gas, coal bed gas etc., the oil gas water of exploration acreage is closed
System is become increasingly complex, and requirement higher is proposed to oil-gas layer identification assessment technique.Especially light oil bed, remaining oil-water-layer,
Reservoir containing mud high and volcanic rock Gas-Water Contant judge that difficulty is bigger, only rely on conventional individual event mud logging techniques to the qualitative of oil-gas Layer
Explanation can not meet the demand of fine evaluation.By the unremitting effort of a large amount of well logging workers, well logging is recorded from tradition
Well has been marched toward new stage of modern overall merit well logging, forms in-situ data collection, data, treatment, hydrocarbon zone interpretation evaluation
Trinitarian modern well logging new technology, plays more and more important effect in Oil And Gas Exploration And Development.Compound logging
By technological innovation and development, successively fluorescence analysis and interpretation and evaluation technology etc. under technique of geochemical logging, mirror are applied
To in site mud logging, compound logging is set to realize great-leap-forward development.Attacked by complex hydrocarbon water layer identification and evaluation technology simultaneously
Close, form a whole set of assessment technique system such as light oil bed, remaining oil-water-layer, reservoir containing mud high, gas-water identification evaluation.
Integrated application well logging new technology quantitative assessment oil gas layer method is a very difficult problem, and it is not only needed newly
The application of technology, also with greater need for the multi-disciplinary synthesis such as geological logging, well logging.Wherein, head space gas lighter hydrocarbons well logging is one important
Work, and this work basis be exactly the gas that canned sample loss goes out collection and operation element.
Head space gas refers to be stored in canned landwaste（The heart）Headroom, and the hydrocarbon of gas-liquid equilibrium is reached with lower liquid
Class, the mixed gas of air, hydro carbons therein is landwaste（The heart）Naturally it is desorbed out.Head space gas lighter hydrocarbons well logging is exactly by tank deck
Gas sample product are injected into gas chromatograph and are analyzed, and are kept completely separate the light hydrocarbon component of head space gas, light so as to obtain oil gas
A kind of gently logging method of hydrocarbon hydrocarbon component.Head space gas detection is common C1-C7 hydrocarbon components in crude oil, including 7 positive structures
Alkane, 13 isoparaffins, 8 cycloalkane, 1 aromatic hydrocarbon（Benzene）, totally 29 monomer components.Can only be detected with gas detection logging
C1-C5 hydrocarbon components are compared, headspace gas logging obtain lighter hydrocarbons information more horn of plenty and comprehensively.Landwaste（The heart）Before tinning, gently
Hydrocarbon part volatilization and loss, therefore, head space gas lighter hydrocarbons are substantially landwaste（The heart）In the volatilization of lighter hydrocarbons part after it is " remaining light
Hydrocarbon " is desorbed the result of loss naturally.Compared with the lighter hydrocarbons in prime stratum, lighter hydrocarbons are constituted head space gas lighter hydrocarbons（Component number）Substantially
It is identical, reflect the composition of stratum lighter hydrocarbons, the abundance of head space gas lighter hydrocarbons and the lighter hydrocarbons loss of stratum lighter hydrocarbons abundance and sample tinning,
Degree of volatility is closely related.The relative amount of head space gas lighter hydrocarbons is that lighter hydrocarbons are light in reservoir physical property, oil property, crude oil in stratum
The coefficient result of the factors such as hydrocarbon content, property of drilling fluid.Head space gas lighter hydrocarbons well logging is premised on lighter hydrocarbons abundance, with lighter hydrocarbons
Composition is referred to, and the active degree of lighter hydrocarbons is judged with lighter hydrocarbons relative amount as Main Basiss, then enlivens journey by lighter hydrocarbons
Spend to infer the active degree of oil-gas Layer, be finally reached the purpose that oil-gas Layer sentences knowledge, so, head space gas lighter hydrocarbons well logging is surveyed in oil gas
Play very important effect in spy, and as stated above, landwaste（The heart）It is crucial base that the laboratory of canned sample takes gas work
Plinth work because its be influence head space gas light hydrocarbon analysis the i.e. amount of important step number.
Landwaste（The heart）Canned sample laboratory takes gas and is to ensure that light hydrocarbon component takes the full critical operations for taking standard.Normal conditions
Under, the usual draining for taking gas mode of laboratory operation personnel takes gas method, will collection in worksite tinning canned sample tank it is upright
Come over（Canned sample tank is to be inverted accumulating after gathering at the scene, it is therefore an objective to prevent gas from being volatilized from cover）, it is placed into water, one
Hand holds tank body, and another hand catches polybag, and cover is rotated with the hand for catching polybag, cover outward winding after from landwaste（The heart）
The light hydrocarbon gas that what middle loss went out be gathered in tank headspace will be entered into polybag（Because gas is insoluble in water
's）；Then, operating personnel take out polybag from water and tighten, then gas bleeding is injected into analysis from polybag with syringe
Tested and analyzed in equipment, repeated after having analyzed and above-mentioned take gas operating procedure.This gas mode that takes is original, while
Generally use, because also without the method and apparatus for preferably taking gas from canned sample tank.But, this gas mode that takes is present
Many shortcomings, headspace gas analysis has also been directly influenced.It is summed up, there are several aspects：
1. plastic sleeve pocket is twisted cover and takes gas and polybag can be caused damaged, during gas will spill into air after breakage, so that also
Canned sample gas can be wasted, causes the data that cannot be made up to lose, reduce exploration benefit；
2. what draining took gas is the fresh water of cleaning, is that one kind of freshwater resources is wasted；Meanwhile, will shape after polybag breakage
Into plastic garbage, environment is polluted；
3. the spatial volume of polybag is not quantitative, so, the gas extracted with syringe does not reach quantitative yet, have impact on point
Analysis work quality；
4. after draining takes gas, air must reach over to, the gas that period collects will be subject to not when polybag is taken out from water
With the dilution of degree, gas analysis quality and oil-gas exploration benefit are have impact on；
5. the landwaste in tank（The heart）Drilling fluid is admixed, drilling fluid is mingled with landwaste after operating personnel turn on cover（The heart）Will infect
Fresh water, the pushing time invades bubble will be corroded, so as to compromise the occupational health of operator；
6. tank body is smooth, and shallow thread is with outside cover, cover lid it is very tight in the case of, operating personnel are difficult tank
Lid is turned on, and is wasted time and energy；
7. winter, the temperature of water is low, operating personnel both hands are immersed in cold water for a long time be less useful for it is healthy.
In a word, gas method is taken according to conventional laboratory draining, above-mentioned various possible feelings just occurs during gas is taken
Condition, while there is also such as gas dilution, loss certainty, all these sciences for all having had influence on final light hydrocarbon analysis
And high efficiency, so as to also directly influence the benefit of oil-gas exploration.
