Description
Technical field
This utility model relates to oil exploration technology field, specifically a kind of shale gas gassiness testing stand.
Background technology
Shale gas is to compose to be stored in rich organic mud shale and interlayer thereof, to adsorb with free state for being primarily present mode
Unconventional forage, composition, based on methane, belongs to a class together with " coal bed gas ", " tight gas ".The formation of shale gas and enrichment
There is the feature of self uniqueness, be often distributed in basin in thickness shale hydrocarbon source rock formation bigger, widespread.Shale gas is very
The most by people cognition, but gather ratio conventional natural gas difficulty, along with energy resource is the deficientest, as tradition natural
The useful supplement of gas, people gradually recognize the importance of shale gas.Shale gas main body is positioned at dark-coloured mud shale or high-carbon mud page
In rock, shale gas is to be present in mud stone, high-carbon mud stone, shale and aleuritic texture rock class interlayer with absorption or free state in main body
Natural gas, it can be created in the various stage natural gas main bodys of organic origin and be present in free phase (about 50%)
Crack, hole and other reservoir space.It is present in kerogen, clay particle and pore surface with adsorbed state (about 50%),
Very small amount is stored in natural gas in kerogen, asphalitine and oil with dissolved state and exists in the siltstone of sandwich-like, flour sand
After generating for natural gas in matter mud stone, argillaceous siltstoue, even sandstone formation, the gathering nearby in source bed shows as allusion quotation
The original place Reservoir model of type is bigger with difference such as oil shale, oil-sand, asphalt.
In the exploration and development of shale gas well, petroleum geology worker is except packet-by-packet to analyze boring the lithology met
Outward, also suspicious formation rock the most likely is cored confirmation.After rock core is fetched into ground, first have to rock core
Simply arranging arrangement, major tasks to be done just are by gassiness experiment.Gassiness experiment is exactly by one section
Rock core is put in water, has then seen whether that bubble is emerged from rock core, thus judges whether contain gas (hydro carbons) in rock.
At present, geological logging working site carries out gassiness experiment does not also have the specific professional facility, gassiness experimental tool used to be nothing but
Common bucket or washbowl, it is impossible to meet fine condition and the requirement of gassiness experiment.
After subsurface rock rock core is fetched to ground, geologist to carry out preliminary arrangement to rock core immediately.Typically
Way be, first by core sample along the arrangement of certain direction to stubble, i.e. recover upper in subsurface formations of rock rock core
Lower order, can not overturn, and otherwise will result in the heavy losses in work, because once destroying its suitable in subsurface formations
Sequence will have a strong impact on the analysis work of lower step.After rock core sample tentatively arranges, geologist will be immediately with clear
Water cleans the drilling fluid adhered on core surface gently so that it is exposes rock true qualities, wants carefully during cleaning meanwhile
See whether, at rock surface, bubble occurs, if it find that certain block rock core sample occurs that bubble is accomplished by immediately to this block sample
Product carry out gassiness test, sometimes, gassiness test to be carried out to suspicious specimen.When carrying out gassiness test, it is desirable to have specialty prepares
Clear water, is subsequently poured in washbowl or another bucket with bucket water lift, may find a fish if condition possesses sometimes
Cylinder is tested.Rock rock core is put in water, if having gas (hydro carbons or non-hydrocarbons) in rock, then under the effect of pressure reduction just
From rock, diafiltration presents bubble in water, then floats along the water surface, at this moment with regard to observable out.Bubble has size discrimination, has
Speed is distinguished, and has shape different, all these content situations all showing gas in rock.After one piece of rock test is complete, then take
Another block is put into continuation and is observed, and water is dirty rear does not such as see that bubble will be replaced with clear water immediately, the most repeatedly, until this examination
The rock rock core tested all has been tested, here it is basic program.The rock core sample having obvious bubble to be sealed up for safekeeping immediately, with
Just collection takes gas therein and carries out proximate analysis in chromatograph.Whole gassiness process of the test need numerous personnel to join
With, some water lifts, the pouring having, the replacing filthy water etc. that has, whole work scene highlights busy.Although this is conventional work journey
Sequence, but, really there is all many problems in this intrinsic method:
(1) rinse dosage is very big, and the filthy water toppled over pollutes environment；
(2) frequently change clear water, delay gassiness test period；
(3) observing bubble in washbowl or bucket, the limitation of observing effect is big；
(4) simple glass fish jar is observed, and changes water process loaded down with trivial details；
(5) gas spills into water from rock and is then diffused in air, it is impossible to judge the real content of gas in rock；
(6) on-the-spot without effective gas collecting facility, have impact on the timeliness of gas analysis；
(7) work on the spot of integration cannot realize, and can not play the overall function of geological logging work.
