Description
Technical field
The invention belongs to oil-gas field development physical simulation experiment technical field more particularly to a kind of cementing anti-channelling of inner ring are resistance to
High temperature and high salt fill out sand tube.
Background technique
In the fields such as chemical flooding, the microorganism drive of oil-gas field development, need to pass through indoor physical simulation from macroscopic perspective
Oil-gas reservoir porous media investigates seepage flow behavior, displacement capability and the mechanism etc. of displacing fluid (or displacing agent).Existing Macroscopic physical
Simulation model mainly includes back-up sand physical model pipe, artificial core and natural core three classes, wherein back-up sand physical model pipe due to
The advantages that processing technology is simple, processing cost is low, easy to use have become Macroscopic physical simulation in it is indispensable, the most commonly used and
Using wider physical model.In an experiment, it is ensured that the accuracy of data is really to reflect displacing fluid (or displacing agent) more
Flow behavior and displacement behavior in the medium of hole, it is necessary that displacing fluid can be effectively porous by back-up sand physical model pipe
Medium, this requires in back-up sand physical model inside pipe wall boundary channelling and filled media cannot occur for displacing fluid cannot be in back-up sand
Migration occurs in pipe and leads to channelling.Therefore, work in-process generally all can be coarse by sandpack column inside pipe wall feather plucking, it is expected that
Filled media can be preferably bonded with inner wall, and then a possibility that reduction boundary channelling, while will be filled out using hydraulic compaction apparatus
Filling medium compacting, prevents filled media from migrating.
Currently, the coarse technology of sandpack column inside pipe wall feather plucking is sent out by most traditional lathe process shot-peening texturing (SBT)
Exhibition is electric spark texturing (EDT), and roughness is significantly improved.Such as Chinese invention patent CN2015107264096 is disclosed
A kind of sandpack column pipe comprising ontology, plug, pressure cap, entrance and exit;Model tube body is equipped with sample tap and surveys pressure
Mouthful, plug is located at ontology both ends, and plug is connect with ontology screw, and pressure cap is fixedly connected with plug, and entrance and exit is located at back-up sand
Model pipe both ends, plug are double-round seal plug, and temperature-sensitive heating device, temperature-sensitive heating device and sheet are provided in the shell of ontology
Body is fixedly connected, and inner body wall obtains uniform roughness (being greater than Ra12.5) by electric spark frosting treatment.However,
Although the inner wall roughness handled by electric spark feather plucking significantly improves, but since the coarse inner wall of feather plucking is entirely that rigidity is situated between
Matter, filled media remain difficult to fit closely with inner wall, and the fitting gap formed between the two is still significantly greater than shape between filled media
At hole, so that channelling problem can only be reduced to a certain extent, and cannot thoroughly solve the problems, such as channelling.
Meanwhile common back-up sand method indoor at present is segmenting of compacted back-up sand method: first a certain amount of filled media being added
The dedicated back-up sand head of sandpack column Guan Zhongyong is compacted by hydraulic device, adds a certain amount of filling Jie after then taking out back-up sand head
It is compacted after matter, so repeats again, take out back-up sand head when the last remaining a bit of length space slightly larger compared with back-up sand head length,
It is sealed after filled media is directly filled in space.Since the filled media in last a bit of space is not compacted, tightness is not
Enough, a degree of migration will certainly occur during the experiment for filled media, so as to cause displacing fluid channelling the problems such as.
On the other hand, because high temperature resistant, bearing capacity is strong the features such as, the back-up sand physical model pipe made of stainless steel material is
The most commonly used a kind of physical model pipe of desk research at present, wherein the manufactured model based on 304L and 316L stainless steel
Pipe is easily corroded under the conditions of high temperature and high salt, shows the problem of salt tolerance difference at high temperature, and under high temperature good salt tolerance Kazakhstan
Family name's alloy and titanium alloy are expensive, higher operating costs.
