What factors need to be considered when choosing a Shale Shaker?

Through operating experience and engineering design for the well structure, we can plan a number of operating procedures in drilling operations in advance. When drilling operations in any area, drilling engineering designers often hope to obtain definite legends and explanations in order to select the number of Shale Shaker and the number of shaker screen meshes that match the requirements of the operation. However, because the actual situation on site is often different from the design, it is impossible to provide such a determined legend to the designer. In response to user requirements, the Shale Shaker manufacturer provides a rough flow chart to illustrate the number of shaker screen meshes and the type of Shale Shaker that should be selected for drilling fluid at a certain flow rate. These data are usually empirical values when the oil field is processing water-based drilling fluids, and the equipment is assumed to be in an optimal state. Therefore, it is only for reference in practical applications.


Rheological factors, drilling fluid type, solid phase type and solid phase content, temperature, drilling speed, solid-liquid interaction, wellbore size, wellbore erosion degree and other variables all determine the actual situation of a specific shaker screen when processing drilling fluid Flow rate. The drilling fluid without any solid phase can best reflect the problems of the Shale Shaker. Polymers that are not sufficiently sheared may stick to the sieve or be removed by the sieve cloth. The polymer treatment agent used in drilling fluids to increase the viscosity and gel strength at low shear rates can also reflect the performance of the Shale Shaker. Polymers, such as starch commonly used as fluid loss additives in drilling fluids, are difficult to pass through fine mesh screen cloth (such as API 200 mesh screen cloth). For oil-based drilling fluids or non-aqueous formulated drilling fluids (NAFs), it is also difficult to pass through the shaker screen without sufficient shearing and mixing. The non-aqueous drilling fluid without a fully oil-wetting treatment agent can pass less than API100, and it is difficult to screen the mesh.

The choice of shaker screen cloth depends on the geographical location and geological conditions of the area where the drilling operation is located. The combination of shaker screen cloth used in the Middle East or the Far East may not be suitable for Norway or the Rocky Mountains. For a specific work area, the best choice for the combination of Shale Shaker and the number of units used is to adopt the advice of qualified solids control experts. A record of the use of the Shale Shaker should be established for later use.
