Functions of drilling fluids mud desilter

Drilling fluids mud desilter is the 3nd stage solids control equipment. It is usually used after desander. For mud cleaner used for oil and gas drilling field, 4 inch deciliter cone is the most frequency be used. It can remove solid particle around 30~70 microns.

Working principle of drilling fluids mud desilter

drilling fluids mud desilter

drilling fluids mud desilter

Main part of drilling fluids mud desilter is the hydrocyclone cone (desitler cone). It is a kind of pressure device. The separation process is carried out by employing centrifugal forces. Under pressure, drilling fluid with solid particles will flow into the mud desilter cones, after high rotation, bigger and heavier particle will be threw to cone wall, then slide down till drop in apex and separated out. Clean fluids will be moved out from cone top port. So, there will be 2 rotary gas flow in the drilling fluids mud desilter cone, one is liquid contains quantity big solid flow down as cyclone, the other is smaller solid mixed with gas go up as bow wave.

The angle of the fluid entry has been specifically designed to facilitate the flow and separation. The Cones are made of high durameter polyurethane with optional steel inserts, which ensure consistent productivity.
Desilter Cones remove fine sand and silt down to 30 microns.
Desilter Cones are available of 4″ size that have a 2″ inlet and a 2″ outlet.

Available models of drilling fluids mud cleaner

From design, there are mainly 2 types of mud desilter: with under flow shale shaker or without under flow shale shaker. For different capacity, the desilter cone can be used from 4 each to 24 each. Users can choose suitable models per his jobsite detailed condition.

Double deck shale shaker and High G shale shaker is widely used for oil and gas drilling rigs site.They can be used for both mud solids control or drilling cuttings waste management.

They are both linear motion shale shaker. Many customer do not know the difference of Double deck shale shaker and High G shale shaker. Below is the explanation from world top solids control and waste management equipment manufacturer – GN Solids Control. Let GN tell you the difference of the 2 types of shale shaker and choose the suitable model for your drilling rig.

Double deck shale shaker, linear motion: GNZS703D

double deck shale shaker linear motion

double deck shale shaker linear motion

GNZS703D is the typical double deck shale shaker. It utilized 2 each shaker screen for top deck and 3 each shaker screens for bottom deck.

Advantages of GNZS703D double deck shale shaker

1). For the same API size and the same area bottom shaker screen. double deck shale shaker can treat a bigger capacity. The wide-meshed shaker screen on top deck can separate most big size solids before the mud enter into the bottom deck. It greatly reduce the load of bottom shaker screen.

2). For the same API size and the same screen area shaker screen. double deck shale shaker can separate the drilling mud or drilling cuttings more dryer. As there are 2 times shale shaker separation.

Disadvantage of double deck shale shaker

The double deck shale shaker have advantages of bigger advantage and dryer separation result, but it has some difficult to change shaker screen. And the cost of replacement shaker screen also higher, as there are 5 each screen for a shale shaker.

High G shale shaker, linear motion: GNZS594

linear motion high G shale shaker

linear motion high G shale shaker

GNZS594 is a high G shale shaker model, with linear motion. It uses 4 panel shaker screen. And the shaker screen interchangeable with Swaco Mongoose shale shaker, composite material. It is single deck, relative easy to change shaker screen compared with double deck shale shaker.

Conclusion

So the user can choose shaker type per your drilling rig conditions and per your applications (for solids control or for waste management). If you have a higher solids content, or want bigger capacity, and take more time for screen changing is not problem, you can choose double deck shale shaker. If you prefer fast screen changing, high G shale shaker single deck is better.

Functions of solids control equipment- shale shaker

Solids Control shale shaker is the first stage separation equipment for oilfield drilling mud cleaning system. It utilizes vibrating motor to generate vibrating strength. The vibrating strength drive the drilling mud going through the shale shaker. When the drilling mud go through the shaker screen, clean mud will filter into mud tank. Not allowable bigger solids will pass the screen surface and been discharged.

Types of solids control equipment – shale shaker

Per different motion design. There are mainly 2 types of shale shaker:

1) Linear motion shale shaker. It is the most common shaker model for oil and gas drilling solids control system

2) Balanced Elliptical motion shale shaker. It is not recommended for oil and gas drilling, as the flow capacity is big. The BEM shaker, while mud flow not equal, the motion of the shaker will be changed. And performance not good. Mostly, professional users prefer linear motion for a wide use.

Separation size of solids control equipment – shale shaker

The separation size of the shale shaker equipment depends on shaker screen size. We call it API size or mesh size. The API defers from API 20 to API 325 per API RP13 standard.

Through changing different API size shaker screen, the solids control shale shaker can separate solids size min. above 40 microns (at API 325 shaker screen)

If you do not need to separate so fine solids, you can choose more fine shaker screen, Like 800 microns @ API 20.

The common screen API size for solids control shale shaker is API60, API80, API100, API140,API160. Customer can choose the suitable size per drilling mud condition.
