Drilling fluids solids control in drilling mud system 1

Drilling mud system, also called as drilling fluids, is a mix liquids used in the process of drilling deep oil or gas wells. The drilling mud is an integral part of the drilling process, serving a number of functions.

solids control system

One of the most critical roles of this drilling mud is as a lubricant. Drilling causes tremendous friction, which can damage the drills or the formation being drilled. Drilling mud cuts down on the friction, lowering the heat of drilling and reducing the risk of friction-related complications.

solids control system

The mud also acts as a carrier for the materials being drilled, with material becoming suspended in the mud tank and then being carried up the drill to the surface. Different muds can all be used for different circumstances. There are water, oil, and gas-based muds which made from true mud mixed with materials like bentonite clays to synthetic drilling fluid.

Due to its high cost, drilling mud system is recirculated throughout the drilling process. As it rises to the surface, it passes through shale shaker that screens the materials from the borehole, before being cycled back into the drilling mud system that delivers mud to the head of the drill bit. This recirculation process, called as drilling fluids solids control, is designed to cut down on waste by reusing as much mud as possible.

The Structure of Shale Shaker 3

Different brands of shale shaker have different methods of fulfilling these demands by using specialized screen tensioning apparatus, rubber seals around the screens, basket reinforcement to limit flex, rubber Float Mounts rather than springs, rubber Deck seals and selective vibrator placement.

shale shaker
Basket Angling Mechanism- The shaker basket must be capable of changing its angle to accommodate various flow rates of drilling fluids and to maximize the use of the shaker screen bed, this is where the angling mechanism plays an important part.

A vibrator is a specialized motor built for the purpose of vibrating, While containing an electric motor to provide the rotary motion it uses a set of eccentric weights to provide an omnidirectional force. To produce the proper Linear motion a second, counter rotating, vibrator is added in parallel to the first. This is what gives us the linear motion, “high G” shaking of the basket.

The Structure of Shale Shaker 2

Feeder- The Feeder is essentially a collection pan for the drilling fluid before it is processed by the shaler shaker, it can come in many different shapes and sizes to accommodate the needs of the mud system. The most commonly used feeder is known as the weir feeder, the drilling fluid enters the feeder usually through a pipe welded to the outside wall near the bottom of the feeder tank, it fills the feeder to a predetermined point and like water flowing over a dam the mud (drilling fluid) spills over the weir and onto the screening area of the shaker.

shale shaker

This method of feeding the shaker is most widely used due to its ability to evenly distribute the mud along the entire width of the shaker allowing for maximum use of the shaker screen deck area.

 

Some feeders can be equipped with a bypass valve at the bottom of the feeder which allows the drilling fluid to bypass the shaker basket and go directly into the hopper and back into the mud system without being processed by the shaker screens.

Jet mud mixer
Screen Basket- Also known as the screen “bed” it is the most important part of the machine, it is responsible for transferring the shaking intensity of the machine, measured in “G’s”, while keeping the “shaking” motion even throughout the entire basket. It must do all that while holding the screens securely in place, eliminating drilled solids bypass to the mud hopper and allowing for easy operation and maintenance of the machine.
