Fig. 1 shows a module structure of a flow rate test device for an injection well injection profile provided by an embodiment of the present invention, and only parts related to the embodiment of the present invention are shown for convenience of description, and detailed description is as follows:
as shown in fig. 1, a flow rate test apparatus for injection well injection profile, comprising:
the device comprises a torque transmission module 10, a torque conversion module 11 fixedly connected with the torque transmission module 10, and a data processing module 12 in communication connection with the torque conversion module 11;

The applicant found in research that the turbine in the conventional turbine flowmeter rotates continuously when in use, so that the turbine component is easy to damage; meanwhile, the traditional turbine flowmeter needs larger flow to drive the turbine to rotate, so that the turbine flowmeter is normally used. In view of this, the applicant inventively proposes a flow rate testing device for injection well injection profiles, wherein the torque transmission module 10 is fixedly connected with the torque conversion module 11, so that the torque transmission module 10 generates a certain torque due to the impact of the fluid, rather than a rotation, and the generated torque is a static torque. Therefore, the flow rate testing device of the injection profile of the injection well has no rotating part, and the generated torque is static torque, so that the accuracy of the flow rate test of the injection profile and the stability of the test can be improved. In addition, the flow rate testing device for the injection profile of the injection well, which is proposed by the applicant, can drive the torque transmission module 10 to generate static torque only by a small amount of fluid or by the fluid with a low injection speed, has the characteristics of high sensitivity and high testing precision, and can particularly improve the low-displacement testing precision and the testing stability.
When the injection well injection profile flow testing device is used, the torque transmission module 10 generates static torque due to impact of fluid of an injection profile, the generated static torque is transmitted to the torque conversion module 11, the torque conversion module 11 converts the acquired static torque into an electric signal corresponding to the torque, the torque conversion module 11 sends the electric signal corresponding to the torque to the data processing module 12 in a wired or wireless mode, and the data processing module 12 can process the electric signal after receiving the electric signal to obtain the injection well injection profile flow of the fluid.
In an embodiment of the invention, a flow rate testing apparatus for an injection well injection profile comprises: the device comprises a torque transmission module 10, a torque conversion module 11 fixedly connected with the torque transmission module 10, and a data processing module 12 in communication connection with the torque conversion module 11; the torque transfer module 10 is used for transferring static torque generated by fluid impact to the torque conversion module 11, the torque conversion module 11 is used for converting the static torque into an electric signal and sending the electric signal to the data processing module 12, and the data processing module 12 is used for determining the fluid flow rate of an injection well injection profile according to the electric signal. In the invention, because the flow testing device of the injection profile of the injection well has no rotating part, the torque transmission module 10 is fixedly connected with the torque conversion module 11 and does not rotate, the torque conversion module 11 acquires static torque through the torque transmission module 10, and further determines the fluid flow of the injection profile according to the acquired static torque, so that the testing precision and the testing stability can be improved, particularly the small-displacement testing precision and the testing stability can be improved.
Fig. 2 shows a schematic structure of a flow rate testing device for an injection well injection profile provided by an embodiment of the present invention, and for convenience of explanation, only the parts related to the embodiment of the present invention are shown, and the details are as follows:
as shown in FIG. 2, in one embodiment of the present invention, the torque transfer module 10 includes a turbine 100.
In one embodiment of the present invention, the torque conversion module 11 includes a torque sensor 110. The torque sensor 110 has a length ranging from 400 mm to 600 mm and a diameter ranging from 38 mm to 42 mm. In one embodiment of the present invention, the torque sensor 110 has a length of 400 mm and a diameter of 38 mm.
In an embodiment of the present invention, the torque transmission module 10 is fixedly connected to the torque conversion module 11, and includes:
The turbine 100 is a rotary power machine that converts energy of a flowing working medium into mechanical work. In the invention, the turbine 100 which originally rotates in operation is creatively welded on the torque sensor 110 through the turbine shaft 101, so that the turbine 100 does not rotate under the impact of injection profile fluid, but generates static torque, the generated static torque is transmitted to the torque sensor 110, the torque sensor 110 collects the static torque, and the torque sensor 110 converts the collected static torque into a corresponding electric signal.
The voltage signal of the torque sensor 110 and the torque have a positive correlation linear relationship, that is, the larger the torque collected by the torque sensor 110 is, the larger the voltage signal corresponding to the torque is, the smaller the torque collected by the torque sensor 110 is, and the smaller the voltage signal corresponding to the torque is.
In an embodiment of the present invention, the torque sensor 110 is a strain gauge torque sensor 110. The strain gage torque sensor 110 employs an electrical strain measurement technique in acquiring torque. That is, a strain gauge is attached to the elastic shaft of the strain gauge torque sensor 110 to form a measuring bridge, and when the elastic shaft is slightly deformed by a torque, the resistance value of the bridge changes, and the change of the resistance of the strain bridge is converted into the change of an electric signal, thereby realizing torque measurement. Therefore, the strain gauge torque sensor 110 has the characteristics of high sensitivity and high measurement accuracy, and can improve the measurement accuracy and the measurement sensitivity of the fluid flow rate of the injection profile, particularly the small displacement measurement accuracy and the measurement sensitivity.
As shown in FIG. 2, in one embodiment of the present invention, the data processing module 12 includes a host computer 120.
In an embodiment of the invention, the data processing module 12 determines a fluid flow rate of an injection well injection profile from the electrical signals, comprising:
the data processing module 12 determines the fluid injection rate from the electrical signal;
the data processing module 12 determines the fluid flow rates of different injection profiles according to the fluid injection rate and the displacement of the injection well.
The injection profile fluid has a certain injection speed, and under the impact of the injection profile fluid, the torque transmission module 10 generates a static torque, which is in a positive correlation with the injection speed of the injection profile fluid, i.e., the larger the injection speed of the injection profile fluid is, the larger the static torque generated by the torque transmission module 10 is, and the smaller the injection speed of the injection profile fluid is, the smaller the static torque generated by the torque transmission module 10 is.
Therefore, in order to investigate the relationship between the injection velocity of the injection profile fluid and the electrical signal (the electrical signal corresponding to the static torque generated by the torque transmission module 10 under the impact of the fluid having a constant injection velocity), the applicant first performed qualitative experiments and quantitative calibration on the relationship between the injection velocity of the injection profile fluid and the static torque generated by the torque transmission module 10 under the impact of the fluid having a constant injection velocity.
Firstly, the applicant adjusts the injection speed of the injection profile fluid from low to high in sequence under the conditions that the pipe diameter of the injection profile is 50 mm and the water temperature is 30 ℃, and measures the experimental data of the torque corresponding to a plurality of groups of different injection speeds as shown in the following table:
| fluid flow (t/h) | Injection velocity (m/s) | Torque (10)-4N·m) |
| 0.1 | 0.013 | 6290 |
| 0.5 | 0.063 | 6340 |
| 1.0 | 0.127 | 6740 |
| 2.0 | 0.254 | 7290 |
| 4.0 | 0.508 | 8078 |
| 6.0 | 0.761 | 9350 |
| 8.0 | 1.015 | 10320 |
Watch 1
As can be seen from table one (or the injection speed and the torque in table one are respectively taken as the amount on the horizontal axis and the amount on the vertical axis of the coordinate system, and a coordinate relation graph of the injection speed and the torque is identified), the measured data has small discreteness, linear fitting is tried on the injection speed and the torque, and a linear correlation coefficient R between the injection speed and the torque is found to be 0.99, which indicates that the injection speed and the torque have good linearity.
In order to verify the correctness of the above-mentioned conclusion, the applicant has repeatedly measured the flow rate measuring device of the same injection well injection profile, and has examined the accuracy and consistency between the results, and can roughly determine the measurement error of the flow rate measuring device of the injection well injection profile. Table two shows data from 5 replicate measurement experiment tests:
watch two
The above conclusions were verified by analyzing the above experimental data: the correctness of the linear relationship between injection speed and torque was confirmed while the relative error of the experiment was kept within 2%.
In an embodiment of the invention, the electrical signal is linear with the fluid injection velocity.
From the above experiment, it can be known that the injection velocity of the injection profile fluid and the torque have a good linear relationship, and further, according to the linear relationship between the electric signal of the torque sensor 110 and the torque, it can be concluded that the electric signal of the torque sensor 110 and the injection velocity of the injection profile fluid also have a linear relationship. That is, the larger the injection rate of the injection profile fluid, the larger the electric signal output by the torque sensor 110, and the smaller the injection rate of the injection profile fluid, the smaller the electric signal output by the torque sensor 110.
In an embodiment of the invention, the electrical signal comprises a current signal and/or a voltage signal. In order to provide a proper measurement range for the flow rate testing device of the injection well injection profile, the range of the current signal output by the torque sensor 110 comprises 4mA-20mA, and the output range of the voltage signal comprises 1V-5V.
Furthermore, before using the flow rate measuring device of the injection well injection profile, for example, before manufacturing and shipping, the flow rate measuring device of the injection well injection profile is calibrated, and then the flow rate of the injection well injection profile is measured by using the calibrated flow rate measuring device of the injection well injection profile.
Fig. 3 is a schematic representation of fluid flow rate determination for injection well injection profiles provided by embodiments of the present invention, showing only embodiments relevant to the present invention for ease of illustration, detailed as follows:
as shown in FIG. 3, assume that the displacement of a stratified injection well is Q (unit: m)3H), determining that the injection speed of each injection profile fluid is V respectively by using an electric signal corresponding to the injection speed of each injection profile fluid output by the flow rate testing device of the calibrated injection well injection profile1(unit: m/s), V2(unit: m/s) and V3(unit: m/s).
To this end, when determining the fluid flow rates of different injection profiles according to the fluid injection rate and the displacement of the injection well, the data processing module 12 determines the following:
fluid flow rate Q of first layer injection profile1Comprises the following steps: q1＝Q*(V1-V2)/V1；
Fluid flow rate Q of first layer injection profile2Comprises the following steps: q2＝Q*(V2-V3)/V1；

In addition, the temperature and pressure acquisition module 13 is detachably connected with the torque conversion module 11, so that the flexibility of the flow rate testing device of the injection profile of the injection well can be improved.
