Stirring type sample mixing device

Abstract

The invention relates to a stirring type sample mixing device. A magnetic coupling rotating mechanism and a retractable multistage rotating impeller are mounted on the device; and a stirring shaft of the retractable multistage rotating impeller can extend and retract along the motion of a floating piston. The magnetic coupling rotating mechanism can ensure that a motor output shaft can be separated from the stirring shaft without contact, which basically solves the problems that the complex system solution in the sample mixing device needs to be stirred and the stirring shaft needs to be sealed dynamically when the device is in a full-closed state and guarantees the uniformity and the stability of the complex system solution and the accuracy of the final experimental result.

Description

technical field [0001] The invention relates to a device for physical simulation experiment of oilfield enhanced recovery research. Background technique [0002] With the development and popularization of computer technology, the degree of automation, test speed and test accuracy of oil field development experimental instruments have made great progress, and the development trend is standardization, serialization and automation.

The test and research of interacting multi-phase seepage, and then develop to the phase state research of fluid and the experimental research of complex multi-dimensional physical model, as well as the test of various chemical agent properties and components, and the effect of compound flooding to enhance oil recovery...

AI Technical Summary

Problems solved by technology

[0003] Various composite system solutions need to be injected in the oil field EOR experiment, and the composite system solution needs to be loaded into the ordinary sampler during the experiment, combined with figure 1 As shown, the common sampler includes a bracket 1, a cylinder body 2, an upper head 3, a lower head 4, a piston 5, a heating ring 6, and a heat preservation jacket 7, wherein the composite system solution is injected into the upper part of the piston 5 through an interface 8. In the cylinder, water is injected into the cylinder below the piston 5 through the interface 9, and the water pressure increases to move the piston 5 upwards, thereby transferring the composite system solution stored in the upper part of the cylinder to the specified model; There is no stirring device on the device, so the composite system solution will be stratified during storage, resulting in the final test result not being able to truly reflect the oil displacement effect of the composite system; Dynamic sealing problem
