Description
Technical Field
The invention relates to a device and a method for testing the surface tension of a high-temperature and high-pressure liquid under the action of artificial seismic waves, belonging to the technical field of the technology for improving the recovery ratio by the physical method of the artificial seismic waves and the mechanism research.
Background
The surface tension is generated by the unbalanced stress of molecules on the surface layer of the liquid, and the surface tension is a special physical and chemical property of the surface of the liquid, and the surface tension exists between any two immiscible phases. In oil reservoirs, interfacial tension is ubiquitous, and the wettability and capillary force of rocks are both related to interfacial tension. Therefore, the research on the interfacial tension in the oil reservoir has important significance on the aspects of improving the oil-water displacement effect and increasing the crude oil recovery ratio.
The artificial seismic wave oil extraction is a novel physical oil extraction mode, and the high-power seismic waves are acted on an oil reservoir, so that the crude oil recovery rate can be increased. Earlier experiments show that under the action of artificial seismic waves, liquid drops on a plane can deform, and meanwhile, the surface tension and the interface tension can be changed by research and inference of the artificial seismic waves. At present, a plurality of methods such as a static drop method, a maximum bubble pressure method, an electromagnetic suspension method and the like are available for measuring the surface tension, however, the methods are all completed under a static condition, and the measurement of the interface tension under a dynamic vibration condition has certain difficulty. For example, under the action of artificial seismic waves, the shape of a liquid drop in a static dropping method can be changed, the surface tension is calculated according to the shape of the liquid drop shot by a camera, the measurement result is inaccurate, and the shooting effect under different vibration parameters has great influence; the electromagnetic suspension method has larger error due to the influence of gravity and magnetic field force, and the measurement result is more inaccurate under the action of artificial seismic waves; the maximum bubble pressure method is affected by the flow rate of bubbles and the depth of capillary insertion when measuring the surface tension of a liquid, but the effect is easier to solve. By considering the advantages and the disadvantages of different methods for testing and calculating the surface tension, the method for testing the surface tension of the double-capillary maximum bubble under the action of the low-frequency artificial seismic waves is designed, and the influence caused by the insertion depth of the capillary and the shaking under different vibration parameters is overcome. Therefore, the device and the method for testing the surface tension of the high-temperature and high-pressure liquid under the action of the low-frequency artificial seismic waves are established, the understanding of the oil extraction mechanism of the low-frequency artificial seismic waves can be further deepened, and the further popularization of the technology is promoted.
Patent CN 104865167A-a high-speed, temperature-controllable dynamic interfacial tension meter and test method describes a method for measuring surface tension, which adopts a Young-laplace equation fitting method of a real liquid drop method, and extracts the graphic data by obtaining the geometric figure of the liquid drop for fitting the contact angle and the interfacial tension value. Patent CN 109100485A-a measurement method of a micrometer capillary gas-liquid dynamic phase interface test system also needs to acquire images. If the equipment for obtaining the real and clear image of the liquid drop under the seismic wave condition is expensive and is difficult to capture the image under the dynamic condition, the shape of the liquid drop can deform constantly under the action of artificial seismic waves, and the average image shape at any moment or all moments can cause a large amount of complex data processing and data decision, so that the calculation error is large.
