Description
Technical field
This utility model belongs to oil-gas field development field, is specifically related to a kind of rock core spontaneous imbibition displacement of reservoir oil measurement apparatus.
Background technology
Along with deepening continuously unconventional reservoir research, increasing production mechanism is revealed.At Study In Reservoir fracturing process
Time, find that the petroleum resources being present in its content is also had necessarily while reservoir is carried out pressure break by the fracturing fluid used
Displacement effect.Compared with conventional sandstone reservoir, the spontaneous imbibition of low permeability gas reservoir reservoir, particularly clay shale with low permeability gas reservoir
Ability is higher, and this allows for fracturing fluid time shale reservoir is carried out pressure break, the super dryness having due to rock itself, powerful hair
The effect of tubule power and clay chemistry power etc. so that fracturing fluid to matrix flow, enters substrate and the seam of inside thereof from crack
In gap.The fracturing fluid being entered substrate and internal interstices thereof by imbibition displacement can go out its internal petroleum resources, thus improves oil gas
The recovery ratio of resource, creates more preferable economic benefit.
In order to study fracturing fluid to the phenomenon of reservoir displacement effect and effect, a kind of driving device is needed to test.Mesh
Before, conventional spontaneous imbibition measurement apparatus is roughly divided into two classes, and a class weighs the change of core quality after suction liquid by balance
Changing, a class is the change being weighed by graduated cylinder and discharging core fluids volume.
At present, in carrying out Equations of The Second Kind experiment.Saturated oils rock core needed for experiment is handled and is put into well the reality installing displacement liquid
After testing instrument, displacing fluid will penetrate in rock core substrate and gap thereof by the way of spontaneous imbibition, by its internal fat oil displacement
Out.Density due to oil is less than the density of displacing fluid, so can be floated to liquid upper strata by displacement oil out.By observing
Float to the oil column in graduated glass tubing, can intuitively learn that imbibition is entered the displacing fluid displacement of rock core and gone out how much oil.But
It is, in experimentation, in the oil droplet part that driven liquid displacement goes out can float to carry graduated reflex glass pipe, one
Dividing and then can adsorb at core surface, this just causes impact to precision of experiment metering so that experimental data is more inclined than actual value
Low, it is impossible to be accurately obtained experimental result.
Therefore to study this process more preferably, more accurately, need on original instrument and equipment, carry out Optimal improvements.
Summary of the invention
The technical problem to be solved is to provide a kind of rock core spontaneous imbibition displacement of reservoir oil measurement apparatus so that the device after improvement
The oil droplet at core surface can be adsorbed after being gone out by displacement scrape so that it is floating entrance is in the glass tubing of metering, it is achieved real
The accurate measurement tested.
For solving above-mentioned technical problem, the technical scheme that this utility model is used is:
A kind of rock core spontaneous imbibition displacement of reservoir oil measurement apparatus, its structure includes: gauge line, test bottle, core holding unit, test bottle
Base, tests rock core, oil-scraping device, packing device, frizing rocking bar, it is characterised in that: described gauge line is positioned at test bottle
Top, it is possible to measuring and discharge crude oil volume, described test bottle base is positioned at below test bottle, can after separating with test bottle
Placing object in bottle, described core holding unit is placed on the bottom surface within test bottle, and described experiment rock core is fixed on
On core holding unit, described oil-scraping device is connected through the packing device on test bottle sidewall with frizing rocking bar, described packing
Device can make the water in bottle not flow out from test bottle sidewall, and frizing rocking bar can control oil-scraping device kinestate, will test rock
The oil droplet in heart wall face scrapes.
By such scheme, the graduated hollow circular-tube of band that described gauge line is isometrical, measurable scope is from 0.5ml-2.0ml
?.
Design principle of the present utility model:
Due to hollow billet wetting effect, after the hydrophilic saturated crude oil of rock core when putting in water, rely on the spontaneous of capillary force initiation
Water can be sucked in rock core by imbibition effect, simultaneously also has a certain amount of crude oil to be discharged, the crude oil volume being discharged by measurement with
The change of time can draw spontaneous imbibition curve.But, owing to the factor impact such as viscous force of crude oil can make a part be discharged
Crude oil be bonded on rock core wall, the crude oil volume making measurement is inaccurate.In this device, will mainly by special oil-scraping structure
The oil droplet being attached to rock sample surface scrapes.Operating procedure is as follows:
(1) first the rock core used by experiment is processed into the specification specified, then puts it into drying baker and dry, drying chamber
Temperature is set to 105 degrees Celsius, general dry six hours after quality no longer change, think rock drying.Rock after drying
Heart saturated oils, fully saturated at it and fix with core holding unit after drying the oil of Adsorption on Surface.
(2) injecting displacing fluid used by appropriate experiment in test bottle, the page is higher than major part scale in gauge line.Will experiment
Bottle base (being connected to core holding unit and experiment rock core) is connected and by contact surface good seal with test bottle, can start experiment and survey
Amount.
(3) in recording gauge buret, first to rotate frizing rocking bar when the size of oil column, the oil droplet of experiment core surface absorption is scraped
Fall so that it is in floating entrance gauge line, so can record the oil mass that displacing fluid displacement goes out more accurately.Gone out by record displacement
Oil mass contrast again saturated enter rock core total oil mass, the recovery ratio size that displacing fluid works can be learnt.
The beneficial effects of the utility model:
Be can be seen that by above-mentioned principle design, a kind of rock core spontaneous imbibition displacement of reservoir oil measurement apparatus that this utility model provides has as follows
Advantage: instrument is easy, portable and carrying, all can test under major part environment, also can meet under some heating conditions
Experiment measure；Simple to operate, use the principle of spontaneous imbibition to test, only the rock core handled well need to be put into experimental provision
In, record experimental data；Compared with conventional experimental provision, the mode wiped off at the oil droplet of core surface will be adsorbed with crossing,
Make experimental data more accurate.
