Acid and alkali resistant rapid liquid mixing application sample separation device and method

Abstract

The invention belongs to the technical field of oil production engineering. An acid and alkali resistant rapid mixing liquid application sample separation device, which comprises a feeding part, a mixing part and a liquid storage sample separation part; the feeding part is used for containing a solution to be mixed; the mixing part is arranged at the bottom of the feeding part and is used for uniformly mixing a to-be-mixed solution; the liquid storage and sample separation part is arranged at the bottom of the mixing part and is used for storing the mixed solution and sampling in groups. The invention further discloses an acid and alkali resistant rapid mixing liquid application sample separation method. The problems of acid-base solution mixing and sample separation can be solved, and static liquid mixing and sample separation are achieved through fluid mechanics. The static liquid mixing and sample separating device is reasonable in overall structural design, can be applied to strongacid or strong base or other liquid with the viscosity smaller than 200 mPa.s, is internally provided with no electronic driving assembly, and achieves static liquid mixing and sample separating by means of the hydromechanics principle.

Description

technical field [0001] The invention belongs to the technical field of oil production engineering, and in particular relates to an acid and alkali-resistant rapid mixing liquid application sampling device and method, which are used for oil field chemical product detection and liquid mixing. Background technique [0002] In the fields related to oil and gas field exploration and development, it is widely used in liquid chemicals, such as oil field completion fluid (perforation fluid), fracturing fluid, and industrial liquid products with strong acid and alkali. The above liquids all contain solid substances to be dissolved. In theory, they are regarded as inhomogeneous solutions. When such products are mixed or product samples are tested, it is usually used to shake the solution container or swing equipment to achieve uniform liquid mixing, and then pour it in and out for testing. In the container, this kind of disadvantage is that due to different personnel errors during ope...

Problems solved by technology

The above liquids all contain solid substances to be dissolved. In theory, they are regarded as inhomogeneous solutions. When such products are mixed or product samples are tested, it is usually used to shake the solution container or swing equipment to achieve uniform liquid mixing, and then pour it in and out for testing. In the container, this kind of disadvantage is that due to different personnel errors during operation, the liquid mixing is not uniform, which has a great impact on the accuracy of the test results; for the mixing and sampling process of strong acid or strong alkali liquid, when the container is more intense When shaking or shaking samples, there are likely to be safety hazards and dangers such as liquid spills or containers falling to the ground, which will affect the normal management of the laboratory and the production and operation of the enterprise.
