Description
Technical field
The present invention relates to a kind of chemical flooding slug automatic switchover system, particularly drive simulation chemical flooding slug automatic switchover system in field about a kind of oilfield chemistry that is applied to.
Background technology
Chemical flooding, as the important technical of mid-late oilfield development " steady oil control water ", more and more causes the attention of researcher.Oil field implements, in chemical flooding technical process, in order to obtain better Flooding Efficiency, can design the injection slug of different volumes.In laboratory physical simulation experiment, need the fluid to rock core injection different volumes, this just needs to switch displacing medium, and method conventional is at present when a kind of fluid is injected into setting volume, and hand needs are dynamic is switched to one other fluid.In the process manually switched, cause data fluctuations, application condition is large.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of simulation chemical flooding slug automatic switchover system, this system can realize switching in the gapless of different slug in displacement test process, and ensure that the continuity of experiment, error is less.
For achieving the above object, the present invention takes following technical scheme: a kind of simulation chemical flooding slug automatic switchover system, is characterized in that: it comprises constant-flux pump, control valve, the first intermediate receptacle, the second intermediate receptacle, six-way valve, rock core, waste liquid recovery apparatus, control cabinet, computer and baking oven; Described constant-flux pump output connects described first intermediate receptacle input side by side through described control valve and the second intermediate receptacle 4 enters end, described first intermediate receptacle output is connected described six-way valve Single port respectively with the second intermediate receptacle output, described six-way valve output port connects described rock core one end, is provided with useless described liquid retracting device bottom the described rock core other end; Described control valve controls its work by described control cabinet, and described control cabinet is transmitted control signal to it by described computer; Described first intermediate receptacle, the second intermediate receptacle, six-way valve, rock core and waste liquid recovery apparatus are all arranged on described oven interior.

The present invention is owing to taking above technical scheme, and it has the following advantages: simulation chemical flooding slug automatic switchover system provided by the invention can be implemented in displacement test process, and the gapless of different slug switches, and ensure that the continuity of experiment.Switching mode experimentally can need sets itself, and by pressure acquisition system Real-time Collection pressure process, and set fluid volume by computer.The present invention can be widely used in oilfield chemistry and drive in raising recovery ratio related experiment.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, the invention provides a kind of simulation chemical flooding slug automatic switchover system, it comprises constant-flux pump 1, control valve 2, first intermediate receptacle 3, second intermediate receptacle 4, six-way valve 5, rock core 6, waste liquid recovery apparatus 7, control cabinet 8, computer 9 and baking oven 10.Constant-flux pump 1 output connects the first intermediate receptacle 3 input and the second intermediate receptacle 4 input side by side through control valve 2, first intermediate receptacle 3 output is connected six-way valve 5 Single port respectively with the second intermediate receptacle 4 output, six-way valve 5 output port connects rock core 6 one end, is provided with waste liquid recovery apparatus 7 bottom rock core 6 other end.Wherein, control valve 2 controls its work by control cabinet 8, and control cabinet 8 is transmitted control signal to it by computer 9; It is inner that first intermediate receptacle 3, second intermediate receptacle 4, six-way valve 5, rock core 6 and waste liquid recovery apparatus 7 are all arranged on baking oven 10.
In above-described embodiment, between constant-flux pump 1 and control valve 2, be also provided with electromagnetic flowmeter 11.
In the various embodiments described above, control valve 2 adopts hydraulic adjusting valve, and the signal that can feed back according to electromagnetic flowmeter 11 changes path section and media flow direction automatically.
In the various embodiments described above, between six-way valve 5 and rock core 6, be also provided with pressure sensor 12, pressure sensor 12 is also connected with pressure acquisition system 13, Real-time Collection pressure process.
In sum, the present invention can realize the automatic switchover during slug of physical analogy chemical flooding solution injection different volumes, the gapless of different slug automatically switches, its operating principle is as follows: by electromagnetic flowmeter 11 to computer 9 delivery flow rate signal, and the closedown controlling to adjust valve 2 by control cabinet 8 by computer 9 or the action of opening.When the solution in the first intermediate receptacle 3 is carried out displacement according to the flow preset by constant-flux pump 1, be injected in sample rock core 6, when injected slurry volume reaches setting value, electromagnetic flowmeter 11 is to computer 9 delivery flow rate signal, control to adjust valve 2 action by computer 9, now, the import and export of the first intermediate receptacle 3 are closed simultaneously, the import and export of the second intermediate receptacle 4 are opened simultaneously, realize the switching of the solution under pressure maintenance.The number of intermediate receptacle, electromagnetic flowmeter can be set according to the number of actual slug.In whole displacement process, computer 9 can store whole test parameters, the volume of injection and pressure.
