This device is used through testing in well site fracturing, and the mixed effect is very ideal, and the degree of consistency reaches more than 98%, has guaranteed the sand carrying ability of fracturing fluid.
For a better understanding of the present invention, the basic working principle and the production application thereof will now be briefly described as follows:
the water is connected on the import pipe check valve 1 with the high-pressure pump outlet pipe, and water gets into this device through main import pipe 2, and additive passes through additive import check valve 3 and additive import pipe 4 entering this device for the dosing pump. Multiple additive inlets can be arranged according to the formula requirement of the fracturing fluid. The additive enters the center of the mixer tube 8 through the perforated support tube 13. The mixed liquid of water and the additive flows into the next porous supporting tube 13 through the central porous guide plate 15, flows to the periphery of the tube barrel, flows into the next porous supporting tube 13 through the peripheral porous guide plates 14, and then flows into the next porous supporting tube 13 through the central porous guide plate 15, so that the mixed liquid turns back and forth, the additive and the water base of the fracturing fluid are uniformly mixed, and the performance of the fracturing fluid is ensured. The mixed fracturing fluid is injected into an oil well or a water injection well through an outlet pipe 11 and an outlet pipe check valve 12 to perform fracturing construction.
At present, liquid fracturing fluid thickeners in the field of oilfield application are of emulsion type and suspension type, and can be mixed and used on site by using the device.
The mixing device can accelerate the mixing of two or more liquid substances.
At present, a polymer is dissolved in water at home and abroad to make a water body become viscous, and two liquids, namely water and a liquid thickening agent, are fully mixed into a uniform liquid, so that a transition process is needed; the device can shorten the time for two liquids (water and thickening agent) to become uniform liquid. The application of oil field fracturing construction requires that the viscosity of a fracturing fluid system reaches 50mpa.s within 30 seconds (or faster), so that the purpose of wrapping fracturing sand and suspending the fracturing sand in the fracturing fluid system is achieved; if the mixture is not fully mixed within 30 seconds, the viscosity of the system does not reach 50mpa.s, and the fracturing sand mixed in the system can be desanded, thereby causing accidents such as sand blocking and the like.
And (3) testing the mixing effect: the mixing effect of the device is characterized by using tap water for liquid preparation at the room temperature of 20 ℃, using the thickening agent with the concentration of 0.6 percent, measuring the viscosity of the system 30 seconds after mixing water and the thickening agent, and comparing the viscosity of the system using the mixing device with the viscosity of the system not using the mixing device, wherein the test data are shown in table 1.
TABLE 1 comparison of system viscosity 30 seconds after mixing of thickener with water
| Viscosity, mpa.s | Emulsion fracturing fluid thickener BY type | Common emulsion type fracturing fluid densifier | Suspension type fracturing fluid densifier BY type | Common suspension type fracturing fluid densifier |
| Use the device | 81 | 56 | 71 | 51 |
| Mixing device without using the book | 36 | 28 | 32 | 23 |
And (4) conclusion: after the device is used, the viscosity of the mixed system of the emulsion type thickening agent, the suspension type thickening agent and water can reach more than 50mpa.s when the mixed system is used for 30 seconds. After the mixing device is used, the viscosity of a fracturing fluid system reaches the standard, the risk of sand removal is avoided, and the construction safety is guaranteed. After the device is used, the viscosity greatly exceeds 50mpa.s after 30 seconds, the proportion of doped sand is increased on a construction site, the original sand doping rate is increased from 30% to 40%, the construction efficiency is increased, and the cost is reduced and the efficiency is improved for oilfield production.
Mixing time comparison test also required to reach a viscosity of 50 mpa.s: at the room temperature of 20 ℃, tap water is used for preparing the liquid, the using concentration of the thickening agent is 0.6%, the BY emulsion type fracturing fluid thickening agent is adopted for testing, the point taking test is carried out within the time range of 10s-90s, and the point taking test is not met after more than 90 s. The mixing effect of the mixing device was characterized by comparing the viscosity of the system with and without the mixing device, and the test data are shown in table 2.
Table 2 comparison of mixing time required to reach a viscosity of 50mpa.s
And (4) conclusion: after the device is used, the viscosity of the system of the thickening agent and water can reach 77mpa.s after 10 seconds, and the requirement of site construction standard of 50mpa.s is met. When the device is not used, the time for the viscosity to reach 50mpa.s is 70 seconds, the sand removal risk of field application is large, the sand ratio is reduced, and the use cost is increased.
