Description

Technical Field

[0002] The mud weighting agent for oilfields plays an important role in the process of oil drilling. Barite powder is a common mud weighting agent for oilfields. The principle of action of barite powder as a mud weighting agent is as follows: in terms of controlling pressure, adding barite powder weighting agent to the circulating mud in the rotary drilling of oil and gas wells in oil drilling can control the pressure of crude oil and natural gas, prevent blowout accidents, stabilize oil and gas production, and in terms of protecting the drill bit and drill pipe, it can cool the drill bit, lubricate the drill pipe, seal the hole wall, and also take away the cut debris.

[0003] At present, when producing mud weighting agents, appropriate raw materials need to be selected, such as barite, iron powder, iron oxide, calcium carbonate, etc. These materials need to undergo strict screening and quality control to ensure the performance of the final product. Then, the raw materials and additives for production need to be mixed and stirred, granulated, and the granulated materials need to be dried to remove the moisture in them to form the finished weighting agent. However, before mixing, the particle sizes of the raw materials are different, which may lead to uneven mixing and affect the performance of the final product, such as fluidity, suspension stability, etc. In subsequent processing steps, such as drying and calcination, uneven particles may cause equipment blockage or wear, affecting the service life of the equipment.
