Description
Technical field
This utility model belongs to oil-gas field development field, is specifically related to a kind of novel rock core spontaneous displacement of reservoir oil measurement apparatus.
Background technology
When Study In Reservoir fracturing process, find the fracturing fluid that used while reservoir is carried out pressure break also to being present in substrate
Internal petroleum resources has certain displacement effect.Compared with conventional sandstone reservoir, low permeability gas reservoir reservoir, the most hypotonic
Thoroughly the spontaneous imbibition ability of shale gas reservoir is higher, and this allows for fracturing fluid time shale reservoir is carried out pressure break, due to rock itself
The effect of the super dryness having, powerful capillary force and clay chemistry power etc. so that fracturing fluid from crack to substrate stream
Dynamic, enter in the gap of substrate and inside thereof.The fracturing fluid being entered substrate and internal interstices thereof by imbibition can be gone out inside it in displacement
Petroleum resources, thus improve the recovery ratio of petroleum resources, create more preferable economic benefit.
In order to study fracturing fluid to the phenomenon of reservoir displacement effect and effect, need a kind of driving device to test, measure
The crude oil volume that the rock core of saturated crude oil flushes out under spontaneous imbibition effect.At present, conventional spontaneous imbibition measurement apparatus is big
Cause is divided into two classes, and a class is weighed by balance and sucks the change of core quality after liquid, and a class is to weigh discharge rock core by graduated cylinder
The change of fluid volume.
In carrying out Equations of The Second Kind experiment.Saturated oils rock core needed for experiment is handled and is put into well the experimental apparatus installing displacement liquid
After, 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.Floated to by observation
With 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,
In experimentation, in the oil droplet part that driven liquid displacement goes out can float to carry graduated reflex glass pipe, a part then can
Adsorbing at core surface, this just causes impact to the precision of experiment metering so that experimental data is more on the low side than actual value, it is impossible to
It is 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 novel rock core spontaneous 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 novel rock core spontaneous displacement of reservoir oil measurement apparatus, its structure includes: gauge line, test bottle, rock core fixing device, experiment
Bottle base, oil-scraping ring, rock core, connecting rod, packing device, it is characterised in that: described gauge line is positioned at above test bottle, energy
The volume of oil is discharged in enough meterings, and described test bottle base is placed in below test bottle, is threaded connection test bottle, described rock
Heart fixing device lower end connects test bottle base, and rock core is fixed in upper end, and described oil-scraping ring is axially transported along rock core by connecting rod traction
Dynamic, described connecting rod is through the packing device on test bottle wall, and described packing device can make to keep test bottle during link motion
Interior water does not flows out.
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.
In this utility model, packing device is made by rubber, it is possible to keeps movable sealing under conditions of link motion, scrapes
Oil ring diameter along rock core axially-movable, can will be attached to the oil of core surface slightly larger than the diameter of rock core, connecting rod traction oil-scraping ring
Drip and scrape.The oil droplet scraped, by buoyancy, can be upwardly into gauge line, and then be measured.
The beneficial effects of the utility model:
Be can be seen that by above-mentioned principle design, the one novel rock core spontaneous 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.
