Drilling bentonite is one of the important raw materials commonly used in drilling engineering. Its function is to increase the viscosity of drilling fluid, maintain its stability, and prevent problems such as wellbore collapse. To ensure the smooth progress of drilling operations, the correct use of drilling bentonite is crucial. The following are the correct usage specifications for drilling bentonite:

1. Select suitable drilling bentonite based on geological conditions and well depth to ensure that it meets the usage requirements under bottom hole temperature and pressure conditions.

2. Drilling bentonite should be screened before use to ensure uniform particle size.

3. Drilling bentonite should be thoroughly stirred in a mixer to mix well with the drilling fluid.

4. During the drilling fluid circulation process, the properties and content of the drilling fluid should be continuously monitored, and adjustments should be made in a timely manner to maintain its stability and fluidity.

5. When the drilling fluid stops circulating or is replaced, sufficient drilling bentonite should be added in a timely manner to maintain the properties and stability of the drilling fluid.

6. The amount of bentonite used in drilling should be reasonably controlled based on factors such as well depth, formation, porosity, etc., to avoid excessive use leading to waste and pollution.

7. After the use of drilling bentonite, it should be treated and disposed of in accordance with environmental requirements to avoid any impact on the environment.

In short, the correct use of drilling bentonite can improve the efficiency and stability of drilling fluid, reduce problems and safety hazards during the drilling process, and ensure the smooth progress of drilling engineering.
