The evaluation device ensures long-term and continuous movement and shearing of the profile control agent by reciprocating motion; the test condition is closer to the real situation by virtue of measures such as temperature control and outlet pressure regulation; and the experimental result has guiding significance.
Description
Technical field
The utility model relates to the experimental facilities field that belongs to shearing behavior, shut-off capacity and the plugging agent dynamic colloid formation behavioral study of plugging agent under reservoir condition.
Background technology
Behind the high water-cut stage, profile control and water plugging technology was as the effective measures of water and oil control during oil-field development entered, and at home and abroad the oil field has obtained widespread use.But rig-site utilization shows that one-tenth glue rule and the indoor static test rule of plugging agent in oil reservoir has a long way to go, and mainly shows the variation on gelation time and the gelling strength.One-tenth glue behavior when how better to estimate plugging agent and migrating under reservoir condition is the problem that the researchist is concerned about always.
At present, the desk research plugging agent is dynamically migrated into the thing mould evaluating apparatus of glue behavior under reservoir condition, its volume is big, precision is relatively poor, need keep transferring stifled liquid to inject continuously during use, shear time has only several hrs in rock core, and constructing continuously with on-the-spot 15-30d differs bigger, so situation and the on-site actual situations of experimental result reaction differ greatly, influence blocking agent type selecting, performance optimization and consumption decision-making, directly influence profile control effect and benefit.
Summary of the invention
The purpose of this utility model provides the whole profile control and water plugging of a kind of simulation construction period and transfers stifled liquid to become glue rule, shutoff situation in the migration process under formation condition, correctly is familiar with the profile-controlling and plugging agent dynamic colloid formation thing mould evaluating apparatus of transferring stifled liquid real conditions in the stratum during the whole construction.
The utility model comprises flow diversion apparatus, liquid stream buffer cell, temperature conditioning unit, fill out sand tube, pressure monitoring unit and control terminal; Two liquid flow exports about described flow diversion apparatus comprises, about two liquid flow exports be connected with liquid stream buffer cell respectively, the endpiece of a liquid stream buffer cell is connected with an end of fill out sand tube, and the endpiece of another liquid stream buffer cell is connected with the other end of fill out sand tube; Fill out sand tube places in the temperature conditioning unit, and the two ends of fill out sand tube are respectively arranged with the pressure monitoring unit, and described control terminal is connected with flow diversion apparatus, is used for the control of liquid stream in the parameters of device.
Principle of work of the present utility model: pumped liquid stream produces the liquid stream of a change direction under different frequency by flow diversion apparatus, being transmitted to the stifled liquid of the accent that promotes in the rock core in the rock core migrates back and forth, the stifled liquid of simulation accent is migrated in rock core and is sheared, by rock core pressure at two ends situation of change, can observe the dynamically migration simulation of gelling strength down of plugging agent.
The utility model adopts to move back and forth and guarantees long-time, mobile, the shearing continuously of the stifled liquid of accent, and by measures such as temperature adjusting, outlet pressure regulation, test condition is more close to on-the-spot truth, and test findings has directive significance.
The pressure that described pressure monitoring unit is used for monitoring fill out sand tube two ends, middle part changes.
Described liquid stream buffer cell is used for replenishing the liquid of circulation pipeline, plays buffer action simultaneously, guarantees the fluid pressure smooth change in the manifold.
Described flow diversion apparatus guarantees that liquid stream by certain flow rate, can change the direction of liquid flow simultaneously.
Control terminal is used for control liquid in parameters such as device flow velocity, flow directions.
Fill out sand tube is used for filling artificial, natural siliceous sand, the metal tube of simulate formation oil reservoir sand body.
Temperature conditioning unit is used for control fill out sand tube internal temperature.
