Facts on how to select drilling fluid filtering system

The drilling fluid filtering systemis function like human heart that provides zero-discharge oh drilling fluid.  Such system is a big ticket items and there are some facts need to consider before make purchase.

1) Type of drill you will be using1500 gpm mud recycling system
2) The drill rate
3) The type of solids
4) The length of your bore
5) The GPM (gallon per minute) of the pump
6) The mud tank volume that will need
7) The number of Hydrocyclones
8) The screen size and API number

These factors determine your usefor drilling fluid filtering system that is adequate enough to clean the mud and protect the components and the drill bit of the rig, pumps and mud cleaners.

Gallons per Minute: When deciding the size of a drilling fluid filtering system that you will need, it is best to double the amount your GPM Need.   For example: If you are pumping 250 gals, you would want consider with a 500-gpm unit.

Trailer or Skid mount: Depending on your requirements, drilling fluid filtering systems can be either trailer mounted or skid mounted. Trailer-mounted units require dedicated trailer (built to unit). Skid-mounted unit can be removed from trailer which releases the trailer for other jobs requirements.

Screen surface: larger screen surface area you have means more volume of drilling fluid that can be process and clean.

Screen selection: The mesh size (API #) of screens is measured by the number of opening per square inch on the screen. Various mesh sizes control the size of the debris that can be removing. The same mesh size will not work in every drilling condition. Sizes will vary depending on the size of the debris and the type of formations you are cleaning.

Shakers: There are three different kinds of shakers (orbital, elliptical and linear). Orbital is a circular motion and elliptical isn’t perfectly circular — it’s an ellipse or oval. Linear has vibration that is induced by a pair of eccentric (or eccentrically weighted) shafts turning in opposite directions. This type of arrangement allows for the development of straight line or linear motion that can also be produced in a positive (uphill) incline.
While each shaker has a specific place that it will stand-out from other choices such as unit selling price, the ability to process heavy clays and rock or fines and ultra-fines, our overall preference of choice is the linear.

Hydrocyclones: Depending on the size of the mud system you choose, the cone size will either be 4 or 10 in. Each size cone has a micron cut point, which is the size of the smallest particle that the cone can pull out. The 4 inch cones have a micron cut of 20 microns and the 10 inch. Have a 74 micron cut.

Decanter Centrifuge: build purpose to filter solids between 2-5 micron and main purpose to recover barite for re-use as additive back into the drilling fluid.  It operates in G centrifugal force that control in fixed or changeable RPM of rotate bowl to achieve separation.
