Description
Technical Field
The invention relates to the field of turbulence drag reduction in hydrodynamics, in particular to a multifunctional drag reduction effect experiment testing device and method.
Background
Since the 20 th century and the 80 th century, in order to improve the conveying efficiency, save energy and reduce consumption, the research on drag reduction is more and more emphasized, and mainly focuses on two aspects of the development of drag reduction devices and the explanation of drag reduction mechanisms. The existing drag reduction modes mainly comprise rib drag reduction, large-scale vortex breaking device drag reduction, surface coating drag reduction, wall vibration drag reduction, additive drag reduction and the like. The additive drag reduction technology has the advantages of small using amount, wide source, simple operation, high drag reduction efficiency (up to 80 percent) and the like, and is widely applied to the field of flow drag reduction.
The oilfield water injection technology is a production increasing technology commonly adopted at home and abroad, and refers to a process of injecting water meeting the water quality requirement into an oil layer through a water injection well by using water injection equipment in the oilfield development process, and supplementing energy to the oil layer so as to ensure the pressure of the oil layer. However, as the demand for water injection increases year by year, a large number of water injection pipelines are limited by the designed output and cannot meet the demand for allocation of oil reservoirs. Therefore, how to reduce the flow resistance of the water injection pipeline and improve the output of the water injection pipeline is a problem to be solved urgently in the development of the current oil field. At present, although the application of the additive drag reduction technology in an oilfield water injection system is rarely reported, the technology is found to have remarkable effect in limited use, such as: by adding the drag reducer into the water injection pipeline, the water injection rate of the Brent Alpha offshore oil field is improved by 34%; the Norwegian Gyde oil field utilizes an additive drag reduction technology to increase the delivery rate of a water injection pipeline by 65% and the like. Therefore, the additive drag reduction technology has wide application prospect and extremely high economic value in drag reduction and transportation increase of an oil field water injection system. How to accurately measure the drag reduction efficiency of a drag reducer is critical to the successful and efficient application of additive drag reduction technology in oilfield flooding systems.
At present, the methods for measuring the drag reduction rate mainly comprise a simulated pipeline method, a capillary rheometer turbulence drag reduction measuring method and a rotational rheometer measuring method. In which the simulated pipe method is widely used due to a closer approximation to the actual pipe flow situation than the other two methods. However, most of the existing experimental devices for simulating the pipeline method adopt pumps to provide required pressure, so that the situation that the mechanical degradation of the polymer drag reducer occurs through the pumps and the drag reduction effect is greatly reduced cannot be avoided, and thus the error of the experimental result is large. Aiming at the problems, the invention provides a pneumatic driving flow device, which can reduce the possible high polymer mechanical degradation to the maximum extent and improve the test precision of the experiment. In addition, the device can realize the research and evaluation of the temperature effect, the concentration effect, the pipe diameter effect, the pipe effect (pipelines with different curvatures, and straight pipes when the curvature is zero), the flow velocity effect and the shearing resistance.
