Description
Technical field
This utility model belongs to petroleum works field, is specifically related to a kind of shale and adds confined pressure imbibition measurement apparatus.
Background technology
Spontaneous imbibition is to occur at natural phenomena common in porous media, for unconventional reservoir, utilizes spontaneous imbibition
It is studied the technology being the most all to compare forward position.In the research of compactness reservoir, particularly to low porosity and low permeability
Thoroughly in the research of shale gas reservoir, the spontaneous imbibition intensity evaluating reservoir rock is the emphasis of research.Firstly, since hyposmosis storage
The throat of layer is tiny, is mostly in micron order even nanoscale, and the spontaneous imbibition phenomena that capillary force causes is than conventional reservoir more
For substantially, the impact producing reservoir is bigger；Secondly, the water absorbing capacity of low permeability reservoir depends on lithology, stratum and manually notes
The kind of liquid entered, needs to carry out a large amount of self-priming experimentation compactness reservoir and the interaction being artificially injected liquid；Simultaneously
The anisotropism of low permeability reservoir is relatively strong, especially in shale gas drilling process, needs Different Strata or same stratum different
The shale of position carries out the evaluation of many sub-samplings.
At present, the spontaneous imbibition for shale both at home and abroad is studied and is concentrated mainly in laboratory environment, at normal temperatures and pressures,
By measuring shale, the suction volume of liquid is conducted a research.But at the scene in operation process, shale is at a few km in underground
With fracturing fluid contacts, the specific environment that this process occurs is High Temperature High Pressure, it is seen that existing research can not simulate page truly
The imbibition process of rock.Therefore, it is badly in need of developing a kind of spontaneous imbibition measurement apparatus for shale.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of shale and adds confined pressure imbibition measurement apparatus, this device bag
Containing a cylinder barrel closed, this cylinder barrel is connected with force (forcing) pump by pipeline, is environment pressurization in cylinder barrel by force (forcing) pump, Ren Men
When carrying out imbibition experiment, it is possible to suitable confined pressure environment is provided according to demand, the phase of more preferable simulated field shale and fracturing fluid
Interaction.
For solving above-mentioned technical problem, the technical scheme that this utility model is used is:
A kind of shale adds confined pressure imbibition measurement apparatus, and its structure includes: force (forcing) pump, pipeline I, pipeline II, plunger, cylinder barrel,
Pressure gauge, control panel, fuselage, it is characterised in that: described force (forcing) pump is connected with Pressure gauge by pipeline I, Pressure gauge energy
Pressure in enough display pipeline I, described plunger is connected with pipeline I by pipeline II, and described plunger and cylinder barrel use screw thread even
Connecing, control panel is placed in body upper, and control panel is embedded with Pressure gauge, and described cylinder barrel is placed in fuselage interior.This practicality
Novel principle is owing to the shale reservoir micro/nano level throat that low porosity and low permeability is saturating is grown, and can there is capillary with water when rock core contacts
Phenomenon, under capillary force action, water can enter in rock core in spontaneous imbibition.By applying a cylinder barrel closed, in cylinder barrel
Pressurization, in rock core is placed in cylinder barrel thus realize confined pressure environment.By timing and measure the quality after rock core absorbs water in time
Change thus reach shale and add the purpose that confined pressure imbibition is measured.
The beneficial effects of the utility model:
By technique scheme it can be seen that this utility model provides a kind of shale adds confined pressure imbibition measurement dress
Putting, this device, by adding a closure cylinder barrel, is that environment pressurizes in cylinder barrel by force (forcing) pump so that measure in original experiment
On the basis of plus confined pressure environment so that shale imbibition process closer to site environment, practicality high, and fuselage entirety can move
Dynamic, convenient, flexibly.
Accompanying drawing explanation
Fig. 1 is this utility model overall schematic.In figure: 1 force (forcing) pump, 2 pipeline I, 3 pipeline II, 4 plungers, 5 cylinder barrels, 6 pressures
Power table, 7 control panels, 8 fuselages.
Detailed description of the invention
Embodiment 1
A kind of shale adds confined pressure imbibition measurement apparatus, and its structure includes: 1 force (forcing) pump, 2 pipeline I, 3 pipeline II, 4 plungers, and 5
