Description

Technical Field

[0001] The utility model relates to the technical field of oil phase production, in particular to an additive adding device for oil phase production. Background Art

[0002] Oil phase production refers to a method of increasing crude oil production and improving reservoir development effects by utilizing natural gas in the reservoir or the phenomenon of natural gas dissolving in crude oil during oil field development. By injecting natural gas or other gases into the reservoir, reservoir pressure can be increased, crude oil can be pushed toward the wellhead, and the recovery rate can be improved. At the same time, the injection of natural gas can also reduce the viscosity of crude oil and the amount of residual oil in the reservoir. Oil phase production technology is of great significance in oil field development and can effectively improve oil field development efficiency and economic benefits. The oil phase production additive addition device is a device used to inject additives into the reservoir to improve the development effect of the reservoir.

[0003] In the process of oil phase production, additives need to be injected into the oil reservoir. The general additive adding device usually includes a mixing tank or mixing chamber, which is used to mix the additives with the inflowing natural gas or other gases. Then, the mixed solution is injected into the oil reservoir through a pump or a pressure system. Although this device has a simple structure and is simple and fast, if quantitative injection of additives is required, traditional adding devices often find it difficult to control the injection amount and mixing quality of the additives, which can easily cause waste of resources or affect the development effect of the oil reservoir. In addition, traditional devices may require more manpower and time to monitor and adjust operations, increasing costs and risks.

[0004] Therefore, in view of the above problems, we need to propose an additive adding device for oil phase production. Utility Model Content
