Wax removal and wax prevention measures for oil wells

Release time:

Jan 10,2022

During the production of oil wells, the wax components in crude oil will deposit on the well wall and pipeline wall, resulting in pipeline blockage and affecting the normal production of crude oil. Therefore, the oil well wax removal and wax prevention work is very important. The following describes several common oil well wax removal wax control measures.

Wax removal and wax prevention measures for oil wells

During the production of oil wells, the wax components in crude oil will deposit on the well wall and pipeline wall, resulting in pipeline blockage and affecting the normal production of crude oil. Therefore, the oil well wax removal and wax prevention work is very important. The following describes several common oil well wax removal wax control measures.

1. hot wash wax

By injecting hot water or steam into the well, the wax is melted, thereby removing the wax from the walls of the well and the pipe. This is an effective way to remove wax, but it requires a lot of heat and water.

2. mechanical wax removal

Use special wax removal tools, such as scraper, wax removal axe, etc., to mechanically dewax the oil well. This method is suitable for oil wells with serious wax removal, but the operation process requires professional skills and care to avoid damage to the equipment.

3. chemical wax removal

The use of chemical agents and wax reaction, so that the wax dissolved or softened, so as to achieve the purpose of cleaning wax. The chemical wax removal method is simple to operate, but it is necessary to pay attention to the selection of appropriate chemicals to avoid damage to equipment and the environment.

4. anti-wax measures

1. Optimize crude oil production parameters: adjust the production parameters of oil wells, such as reducing crude oil production and increasing the rate of liquid production, in order to reduce wax deposition.
2. Additive anti-wax: Add anti-wax agent to crude oil to inhibit the crystallization and deposition of wax. This is an effective anti-wax method, but it is necessary to select a suitable anti-wax agent and ensure its safety performance.
3. Wellhead insulation: the oil well insulation treatment, reduce the temperature drop caused by wax deposition.
4. Regular wax removal: formulate a regular wax removal plan, and select the appropriate wax removal method according to the actual situation of the oil well to ensure the normal production of the oil well.

5. Management and Maintenance

1. Strengthen inspection: regular inspection of oil wells and timely treatment of wax deposits found.
2. Establish archives: record the wax removal of oil wells and establish archives to provide basis for subsequent wax removal work.
3. Training operation staff: training and guidance for operation staff to improve their understanding and operation skills of wax removal and wax prevention in oil wells.

In short, the wax removal and wax prevention work is of great significance to ensure the normal production of oil wells. According to different types of oil wells and actual conditions, appropriate wax removal and wax prevention measures should be selected, and management and maintenance should be strengthened to ensure the long-term stable operation of oil wells.
