Description
Technical field
This utility model is related to a kind of core holding unit in unconventionaloil pool field, particularly a kind of quantitative simulation rock core folder
Holder.
Background technology
Unconventional tight sand oil is mainly existed with free oil (moveable oil) and oily (non-movable oil) state of absorption, fine and close sand
In rock free oil refer to can to flow in compact reservoir under existing DP technology and can from oil reservoir output part oil, inhale
Attached oil refer to not flow in compact reservoir under referring to existing DP technology and can not from oil reservoir output part oil.Fine and close sand
Rock reservoir is broadly divided into i class and ii class, and its oiliness includes oil-containing, oil immersion, oil mark, oil stain etc., and every class Sandstone Gas Reservoir contains
The free oil of oiliness is different with absorption oil mass, gets free oil and absorption oil cloth and feature in Sandstone Gas Reservoir clear, to densification
Sandstone oilreserves, the exploration and development such as effectively to employ significant.
At present, unconventionaloil pool conventional survey sampling technique is it cannot be guaranteed that the initial condition of underground rock core, especially for a long time
The rock core placed, makes free oil scatter and disappear due to departing from underground primal environment and blood pressure lowering, test result can not reflect underground crude oil shape
Condition.There are the experimental techniques such as document report unconventional reservoir analytical equipment, reservoir moveable gel, free hydrocarbon, referring to (1) Liu
A handle of the Big Dipper, accepting a heavy burden " unconventional reservoir different existence state oil analysis apparatus (number of patent application 201320521882.7) ", (2) Zhou Shang
Literary composition, Xue Huaqing, Guo Wei " Jurassic system fine and close oil reservoir movable fluid experiment in river " (Liaoning Project Technology University's journal (natural section
Learn version), the 6th phase in 2014), " NMR logging technique is in western slope Saar oil reservoir group for (3) Ke Qingming
Application " (well logging engineering, the 4th phase in 2013), (4) Wang Min " key parameter and acquiring method research that shale oil is evaluated " is (heavy
Long-pending journal, the 1st phase in 2014) etc..Above-mentioned (1) is directed to after hypotonic, these nontraditional reservoir of ultralow permeable reservoir of China put into exploitation
Recovery ratio is all relatively low, and means such as water drive, polymer flooding etc. of traditional raising recovery ratio are all difficult to improve these nontraditional reservoir
Recovery ratio, improve the problem of the recovery ratio of nontraditional reservoir using the special nature of the carbon dioxide under supercriticality,
A kind of unconventional reservoir different existence state oil analysis apparatus developed, that is, in carbon dioxide before entering displacement model
Reach supercriticality and recycling carbon dioxide, to improve the recovery ratio of nontraditional reservoir, this utility model patent device
Simulated formation temperature can not be solved, quantitative injection tight sand crude oil forms different oiliness (oil-containing, oil immersion, oil mark, oil stain etc.
Oil bearing grade) problem, clearly do not propose how to measure tight sand free oil (moveable oil) and adsorb oily (non-movable oil)
Problem etc.；Above-mentioned (2) application nuclear magnetic resonance technique carries out movable fluid test to fine and close oil reservoir rock sample, obtains fine and close oil reservoir
Moveable gel；Above-mentioned (3) application NMR logging technique acquisition porosity of sandstones, permeability, initial oil are satisfied
With parameters such as degree, mobile oil saturations；Above-mentioned (4) are deduced instead using core analysis datas such as porosity, oil saturations
Reflect the evaluation model of the free hydrocarbon content of dunn bass, by organic carbon in free hydrocarbon organic carbon content absolute value and free hydrocarbon
Content achieves instruction to shale oil formation movable hydrocarbon abundance zone etc. with the ratio of formation organic carbon content.It can be seen that, above-mentioned
Method all can not solve tight sand free oil and the oily quantitative simulation of absorption and test problem.For meeting unconventional densification exploration activity
The needs of exploitation, a kind of quantitative simulation core holding unit of the present utility model, for quantitative simulation tight sand oil with shape
Become the experiment core sample of different oiliness, for subsequently accurately test free oil and absorption oil provide experimental provision.
Content of the invention
This utility model be overcome existing means of testing present in background technology cannot solve tight sand free oil and
The oily quantitative simulation of absorption and the problem of test, and a kind of quantitative simulation core holding unit is provided, this quantitative simulation core holding unit,
The experiment core sample of different oiliness can be formed by quantitative saturation crude oil, test its free oil and absorption oil for accurate, be
Unconventional densification exploration activity exploitation provides geological experiment analysis New Set and foundation.
The invention for solving the technical problem can reach by following technical solution: this kind of quantitative simulation core holding unit,
Including base, fixation clamp holder main body on described base；The built-in lead set of described clamp body, described lead set left and right two ends are divided
Not Lian Jie closure, described clamp body two ends external connection end cap；Described clamp body, end cap female thread connect push rod
One end, described push rod other end connecting valve a and valve b；It is connected with confined pressure interface in the middle of described clamp body.
This utility model can have the advantages that compared with above-mentioned background technology this quantitative simulation rock core clamps
Device, forms tight sand oil laboratory sample for quantitative saturation crude oil and gas drive replaces test free oil, free oil in tight sand
Distribution is very important for unconventionaloil pool exploration and development research.Quantitative simulation and test process are in formation temperature and pressure
It is automatically performed under the conditions of power, vacuum and airtight, irreducible water rock core；After evacuation, saturation crude oil under constant current or constant voltage mode
Form tight sand oil, be that follow-up gas displacement process test free oil provides laboratory sample and device with absorption oil, and reach peace
The requirement that loopful is protected.
