Screening plant is used in fluid loss additive production

Technical Field

The utility model relates to a screening plant technical field especially relates to a screening plant is used in fluid loss additive production.

Background

During the drilling process, due to the action of the pressure difference, the water in the drilling fluid is inevitably lost to the stratum through the well wall, so that the drilling fluid loses water. As water enters the formation, clay particles in the drilling fluid adhere to the wellbore wall to form a "filter cake," forming a filter cake wellbore. As the well wall of the filter cake is much denser than the original well wall, the filter cake prevents the drilling fluid from further losing water on one hand and plays a role in protecting the well wall on the other hand. However, in the process of forming a filter cake well wall, the filtered water content is too much, the filter cake is too thick, and fine clay particles enter the stratum along with the water content, so that normal drilling is affected and the stratum is damaged.

The filtration loss of the drilling fluid and the formation of a filter cake are inevitable in the drilling process, the filter cake can be formed through the filtration loss to protect a well wall, but the filtration loss of the drilling fluid is too large, so that the shale is easy to expand and collapse, and the well wall is unstable. In addition, the filter cake thickens while the filtration loss is increased, so that the well diameter is reduced, a large torque is caused to a rotating drilling tool, swabbing and pressure fluctuation are caused when the drilling tool is tripped out, and differential pressure drill sticking is easily caused. Therefore, proper control of fluid loss is one of the important properties of a drilling fluid.

At present, the filtration loss of the drilling fluid is mainly reduced through the fluid loss additive, so that the quality of the fluid loss additive plays an important role in the effect of the fluid loss of the drilling fluid, but in the production and screening process of the fluid loss additive, the fluid loss additive is powdery, so that a screen is easily blocked, the structure of the fluid loss additive is complex, the ideal screening effect cannot be achieved, and the quality and the material selecting effect cannot be maximized, so that a screening device for producing the fluid loss additive is provided, and the problem is solved.
