Description
Technical Field
The invention relates to the field of petrochemical industry, in particular to a method, a device, a system, computer equipment and a storage medium for joint measurement of emulsifying capacity and emulsion stability of a rotary fluid.
Background
The test and evaluation of the oil-water emulsifying capacity and the emulsion stability are widely applied in the fields of food, medicine, chemical synthesis and the like. For example, in the field of petroleum development, especially in chemical flooding process containing surfactant, the evaluation of oil-water emulsifying capacity and emulsion stability plays a crucial role in perfecting the research and application of chemical flooding theory and technology
In the past, the emulsion preparation for testing the stability of the oil-water emulsion mainly adopts a shaking method, a test tube is shaken to enable oil water to vibrate up and down to form emulsion, a dynamic curve for reducing the amount of the emulsion is measured, the half-life period is determined, and the stability of the emulsion is evaluated. The method is simple and convenient. However, the manual shaking method is difficult to achieve scientific specification, the influence of human factors is large, the repeatability of experimental results is poor, and the temperature in the emulsification process cannot be controlled. Also, the emulsifying ability was evaluated by a mechanical shaking method which enables precise control of the emulsifying conditions and the temperature during the emulsification. Although the method for evaluating the stability of the emulsion based on mechanical shaking for preparing milk overcomes the defects of the hand shaking method, the method still has the following defects: firstly, the emulsification process cannot be judged, and only the final emulsification result is obtained; secondly, the test tube is seriously stuck to the wall in the shaking process, so that accurate reading is influenced; after the experiment is finished, the emulsification zone can be read only after standing for a period of time, the emulsification zone is not the original emulsification amount, and the emulsion can be broken in the waiting process; and fourthly, the external input energy in the traditional mechanical milk making process is always constant, so that the minimum disturbance energy generated by emulsification and the influence on the emulsification effect along with the external energy change cannot be evaluated.
In addition, the prior art also adopts an ultrasonic emulsification method to evaluate the oil-water emulsification capability. However, due to the characteristics of ultrasonic conduction and the complex influence factors of energy attenuation, the ultrasonic energy and the distribution thereof in the emulsification pipe cannot be accurately controlled and measured, so that the oil-water emulsification part has uncertainty; in addition, the particle size of the emulsion formed by ultrasonic emulsification is very small, so that the stability evaluation of the emulsion cannot be carried out by using the emulsion, and the joint measurement of the oil-water emulsifying capacity and the emulsion stability cannot be realized.
Aiming at the problem that the existing emulsion preparation method cannot accurately evaluate the oil-water emulsifying capacity and the emulsion stability, a method, a device and a system for jointly measuring the emulsifying capacity of the rotary fluid and the emulsion stability are needed.

The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of sequences, and does not represent a unique order of performance. When an actual system or apparatus product executes, it can execute sequentially or in parallel according to the method shown in the embodiment or the figures.
It should be noted that the method for jointly measuring the emulsifying capacity and the emulsion stability of the rotary fluid can be used in the field of petrochemical industry, and can also be used in any fields of medicine, pharmacy, chemistry and the like, and the application fields of the method, the device and the system for jointly measuring the emulsifying capacity and the emulsion stability of the rotary fluid are not limited.
Fig. 1 is a flow chart of a method for jointly measuring the emulsifying capacity and the emulsion stability of a rotary fluid according to an embodiment of the present invention, which specifically includes the following steps:
In some embodiments of the present description, the first liquid phase and the second liquid phase are two liquids that are not normally miscible. The first liquid phase may be an oil phase including, but not limited to, crude oil containing various components, and the second liquid phase may be an aqueous phase including, but not limited to, water containing various minerals and surfactants.
In this step, the second liquid phase may be injected first, and then the first liquid phase may be injected into the emulsion test tube. That is, the water phase is injected into the emulsion test tube first, and then the oil phase is injected. And the initial height of the oil phase in the emulsification test tube was recorded. This initial height corresponds to the amount of oil phase injected into the emulsification test tube, and can be used as a reference height for the first liquid phase in the subsequent steps to calculate the emulsification rate and the emulsion breaking rate.
And 102, calculating the emulsification rate of the second liquid relative to the first liquid at a plurality of rotating speeds according to the initial height of the first liquid and the non-emulsification height of the first liquid at each rotating speed of the rotating module. In this step, the rotating module is a part of a rotating module in an emulsion testing apparatus according to the embodiment of the present disclosure, and the rotating module is configured to rotate the first liquid phase and the second liquid phase in step 101, so as to form a stable shear flow field at a phase interface of the first liquid phase and the second liquid phase. Further emulsifying the first and second liquid phases. In some embodiments of the present description, the first liquid phase and the second liquid phase in a rotating state, which are rotated, may be referred to as a rotating liquid. See figure 9 for a detailed description of the rotation module and the emulsification testing device. The rotating module in this step is the rotating module in fig. 9. The non-emulsified height of the first liquid phase may be understood as the remaining non-emulsified height of the first liquid phase in the emulsification test tube, i.e. the remaining height of the first liquid phase. Wherein, the rotation module can provide different rotational speeds, through record incessant rotational speed down the first liquid phase not emulsify height and the initial height of first liquid phase, can calculate the emulsification rate of second liquid phase to first liquid phase under the different rotational speeds.
And 104, determining the emulsification coefficient of the second liquid relative to the first liquid phase according to the emulsification rate of the second liquid relative to the first liquid phase at the plurality of rotating speeds. In this step, each rotation speed corresponds to one emulsification rate, and the emulsification coefficients of the second liquid phase and the first liquid phase can be determined according to a plurality of emulsification rates of the second liquid phase relative to the first liquid phase corresponding to the rotation speeds at a plurality of moments. Wherein the emulsification factor allows to evaluate the emulsifying capacity of the second liquid with respect to the first liquid phase. The emulsifying capacity may be understood as the ease with which the first and second liquid phases form an emulsion.
And 105, determining the emulsion breaking coefficient of the emulsion according to the emulsion breaking rate of the emulsion formed by the first liquid phase and the second liquid phase at the plurality of moments. In this step, the emulsion breaking rate of the emulsion formed by one first liquid phase and the second liquid phase corresponds to each time, and the emulsion breaking coefficient of the emulsion formed by the first liquid phase and the second liquid phase in the state can be determined according to a plurality of emulsion breaking rates corresponding to a plurality of times. Wherein the breaking coefficient may evaluate the stability of an emulsion formed by the first liquid phase and the second liquid phase. Specifically, the smaller the value of the breaking coefficient, the stronger the stability of the emulsion.
FIG. 2 is a flow chart illustrating a method of determining the height of the first liquid phase and the second liquid phase injected into the emulsification test tube according to an embodiment herein.
The standard conditions are experimental conditions under preset standard conditions. The standard conditions include: a standard temperature, a standard interface height of the first liquid phase and the second liquid phase, a viscosity of the second liquid phase or the solution of the active agent to be tested, and the like. In some embodiments of the present description, the standard temperature may be 25 ℃, 30 ℃, etc., and the standard interface height of the first liquid phase and the second liquid phase may be 5 cm, 7 cm, 8 cm, etc.; the viscosity of the second liquid phase or the solution of the active agent to be tested is 0.8, etc. The test conditions are conditions in actual experiments, including: the test temperature, the viscosity of the second liquid phase or the solution of the active agent to be tested, etc. For example, if the test condition temperature is 40 ℃, the viscosity of the second liquid phase at the test temperature is 0.6, the standard temperature is 25 ℃, the standard interfacial height of the first liquid phase and the second liquid phase is 5 cm, the viscosity of the second liquid phase is 0.8, and the first and second liquid phase interfacial shear similarity coefficients C are 1, the interfacial height of the first liquid phase and the second liquid phase at the test condition can be determined to be 3.75 cm according to the formula.
FIG. 3 is a flow chart illustrating a method for calculating an emulsification rate of a second liquid relative to a first liquid phase at a plurality of rotational speeds according to an embodiment of the disclosure. The method specifically comprises the following steps:
The formula in this step represents the first liquid at different angular velocitiesThe emulsion height variation of the phases is a proportion of the initial height of the first liquid phase. Wherein, the larger the emulsification degree of the first liquid phase and the non-emulsification height h of the first liquid phase along with the increase of the rotating speed oi The smaller (w) the emulsification height h of the first liquid phase o0 -h oi The larger (wi) the emulsification height of the first liquid phase takes up the initial height h o0 The larger the specific gravity of (a), i.e., the larger the emulsification rate.
Fig. 4 is a flow chart illustrating a method for calculating a breaking rate of an emulsion formed from a first liquid phase and a second liquid phase at a plurality of times in accordance with an embodiment of the present disclosure.
In this step, h ne After the rotation of the rotating module is stopped, the height of the first liquid phase is determined at the initial moment. Namely, the initial height of the first liquid phase after the emulsification process of the first liquid phase and the second liquid phase in the emulsification test tube is finished. For example, the initial height of the first liquid phase after the emulsification process of the first liquid phase and the second liquid phase is 0 mm, which indicates that there is no clear first liquid phase in the emulsification test tube after the emulsification process is finished, and the first liquid phase is not separated from the emulsification zone generated in the emulsification process.
And 402, controlling a rotating module in the emulsification test tube to stop rotating, and obtaining the height of the first liquid phase at a plurality of moments in a static state. When the rotation module stops rotating, the first liquid phase and the second liquid phase in the emulsification test tube gradually tend to a static state from a high-speed rotating state. In some embodiments of the present description, the first liquid phase and the second liquid phase in the test tube are emulsifiedAfter the process from the high-speed rotation state to the rotation stopping state, based on the influence of liquid inertia and the like, the liquid in the emulsification test tube is really static after waiting for a very short time. The method comprises the steps of taking the whole liquid in the emulsification test tube as a first moment when the liquid is in a static state, and recording the height of the first liquid phase and the dynamic change condition of an emulsification zone at a plurality of moments from the first moment. In the moment after the standstill, the height of the first liquid phase will gradually increase and the height of the emulsification zone will gradually decrease with increasing time, and the first liquid phase will gradually separate from the emulsification zone. In some embodiments of the present description, the height of the first liquid phase at multiple moments of the quiescent state is in h do (t) represents. In this step, h do (t) is the height of the first liquid phase at a plurality of moments after the rotation of the rotating module is stopped. After the rotation of the rotary module is stopped, the first liquid phase in the emulsification test tube is gradually separated from the emulsification zone, and the demulsification phenomenon begins to be generated. Height h of the first liquid phase do (t) will gradually increase with time.
And 403, determining the demulsification amount of the first liquid phase at multiple moments according to the non-emulsified height of the first liquid phase and the heights of the first liquid phase at multiple moments. In this step, the emulsion breaking amount of the emulsion formed by the first liquid phase and the second liquid phase is: the difference between the height of the first liquid phase and the non-emulsified height of the first liquid phase at a plurality of times may be represented by h do (t)-h ne And (4) showing.
In this step h do (t)-h ne Indicating the height increase of the first liquid phase during the breaking of the emulsion. h is do (t)-h ne A larger value of (a) indicates a larger degree of demulsification of the first liquid phase and a higher degree of separation of the first liquid phase from the second liquid phase. Otherwise, h do (t)-h ne A smaller value of (a) indicates a smaller degree of demulsification of the first liquid phase and a smaller degree of separation of the first liquid phase from the second liquid phase.
FIG. 5 is a flow chart illustrating a method of determining an emulsification factor of a second liquid relative to a first liquid phase according to embodiments herein. The method specifically comprises the following steps:
In this step, ω 2 -ω 1 A difference between the maximum rotational speed and the minimum rotational speed, E o,st The reference emulsification rate is the linear increase of the relation between the rotating speed and the emulsification rate at each angular speed. The reference emulsification rate can be considered as a linear function, for example, with a minimum angular velocity of 400 rpm and a maximum angular velocity of 800 rpm. At minimum angular velocity, the emulsification rate is 0; the emulsification rate was 100% at the maximum angular velocity, the angular velocity was independent, and the angular velocity was [400,800 ]]Within the interval, the emulsification rate is linearly increased and is a dependent variable, E o,st Namely, the emulsion ratio shows a change relationship in which the rotation speed increases and the emulsion ratio linearly increases. In this step, the larger the value of the calculated emulsification coefficient is, the stronger the emulsifying ability of the emulsifier is.
Fig. 6 is a flow chart of a method of determining the breaking coefficient of an emulsion according to an embodiment of the present disclosure. The method specifically comprises the following steps:
In some embodiments of the present description, D o,st (t) indicates that at each time, the relationship between time and emulsion breaking rate increases linearly. D o,st (t) can be considered as a linear function, e.g. minimum time 0 minutes and maximum time 0 minutesFor 60 minutes. Wherein, the minimum time is the starting time when the rotation module in the emulsification test tube stops rotating and is in a static state, and the emulsification rate is 0 at the minimum time; the emulsifying rate is 100% at the maximum time, the time t is independent variable, and the time is [0,60 ]]Within the minute interval, the emulsion breaking rate is linearly increased, the emulsion breaking rate is a dependent variable, D o,st And (t) shows that the demulsification rate is in a time-increasing and linear increasing change relationship.
