Rotary rigs drill the vast majority of wells today, including all medium and deep wells. The rotary rig consists of four major systems. These include the engines, and the hoisting, rotating, and mud systems.

General of drilling mud(drilling fluids)

Common drilling mud is made of bentonite clay. A heavier drilling mud can be made by adding barite. Various chemicals are also used in different situations. The drilling mud liquid is usually water but is sometimes oil-based. Drilling mud are described by weight. Water weighs 8.3 pounds per gallon. Average bentonite drilling mud weighs from 9 to 10 ppg. Heavy drilling mud weighs from 15 to 20 pounds per gallon. The heavier the drilling mud, the greater the pressure it exerts on the bottom of the well.

Fluid is circulated while the drilling proceeds. Powerful pumps move the fluid down to the pipe, through the bit and back to the surface, carrying the cuttings and other debris with it. Thus, on a rotary rig , drilling can be continuous as stopping to bail the cuttings is no longer required.  The drilling mud also stabilizes the walls of the hole.

Mud circulation system for rotary rig

Drilling mud is stored in steel mud pits beside the rig. The drilling mud then flows down through the hollow rotating drill string and jets out through holes in the drilling bit on the bottom of the well. The drilling mud picks cuttings from the bottom of the well. It flows up the well in the space between the rotating drill string and well walls.

Drilling mud serves several purposes. The mud removes cuttings from the bottom of the well. As the mud flows across the bit, it cleans cuttings from the teeth. The drilling mud cools the bit from heat generated by the friction of drilling. The drilling mud also controls pressures in the well and prevents blowouts.

GN solids control have designed and manufactured many sets of mud circulation system for rotary rig, both for oil & gas drilling and workover operation. From 250HP to 3000HP land rig, we can provide customized solution for land rig drilling.

As we all know the quality and charactor of the drilling fluid effects the drilling works. The viscosity, density, fluid loss control, sand content, gel strength, and so on. The drilling fluid system is used to control them.
If not use the drilling fluid system correctly, effiently, there must be some trouble. High fluid density causes pressure in the formation of the borehole. This pressure drives the drilling fluid through the filter cake into the formation, leads to excessive drilling fluid loss to the formation, and extends well development time required to remove the mud from the formation. As the fluid density increases, the pressure required to move the fluid up the borehole also increases, leading to high mud pump pressure requirements.

High solids or sand content also leads to significant abrasion in the drill tooling as the fine particles are recirculating through the mud pump and drill string. Washed out drill strings and mud pump valves/seats, along with leaking swivel packing, are caused by the recirculation of sand through the system. If the gravel pack is emplaced in the annulus through drilling fluid with a high sand content, the fines will be entrained in the gravel pack leading to increased well development costs and reduced well yields.

GN Solids Control can supply high qality products, effeciently control the all factors for drilling fluid system, to keep the drilling work operating efficiently.

Centrifugal Pump

A centrifugal pump is a roto dynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping system. Centrifugal pumps are used for large discharge through smaller heads.

Centrifugal Pump With Mecheanical Seal

In some situations, packing material is not adequate for sealing a centrifugal pumps shaft. One common alternative method for sealing the shaft is with mechanical seals. Mechanical seals consist of two basic parts, a rotating element attached to the pump shaft and a stationary element attached to the pump casing. Each of these elements has a highly polished sealing surface. The polished faces of the rotating and stationary elements come into contact with each other to form a seal that prevents leakage along the shaft.

The most effective method of preventing the leakage of the drilling  fluids from the centrifugal pump to the external surroundings is using the mechanical seals. The mechanical seals help sealing the rotating part of the shaft against the stationary part of the pump housing. Let us see more details.

What are Mechanical Seals in Centrifugal Pumps ?

In the centrifugal pumps the rotor, on which the impeller is mounted, revolves in the stationary housing of the pump and there is minor gap between the two. The centrifugal pump pumps a variety of fluids and sometimes these fluids can be highly hazardous to the humans and also the environment.

The most effective method of preventing the leakage of the fluid from the centrifugal pump to the external surroundings is using the mechanical seals. The mechanical seals help sealing the rotating part of the shaft against the stationary part of the pump housing. Thus the mechanical seals are the devices that form the packing between the rotor and the stationary part of the centrifugal pumps to prevent the leakage of the fluid being pumped by the pump. There are two main parts of the mechanical seals: one is the stationary part, which is connected to the pump housing and the other is the rotating part which is connected to the rotating shaft.

Prior to the mechanical seals, the compression packing like gland packing were used as the sealants though they are still being used in number of applications. The mechanical seals are especially used in the process applications where the centrifugal pumps handle hazardous chemicals like HCL, sulfuric acid, etc. to meet the safety and the environmental standards as per the federal regulations.

Linear motion shale shaker

The drill bit grinds rocks into drill cuttings, which are entrained in the mud flow and are carried out to the surface. And we separated the mud from the solids to make the mud return to the recirculating mud system.

The liquid mud passes through the shale shaker screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole. The drill cuttings remain on top of the shale shaker screens; the vibratory action of the shakers moves the cuttings down the screen and off the end of the shakers to a point where they can be collected and stored in a tank or pit for further treatment or management.

Then the drilling mud come to desander and desilter, and the drilling cuts are separated with the hydroclones.

Usage of hydrocyclone

A hydrocyclone is often used to separate drilling cuttings from drilling mud originating at a desander desilter or some other continuous source of pressurized liquid. A hydrocyclone is most likely to be th

e right choice for processes where “lights” (drilling fluids, e.g.) are the greater part of the mixture and where the “heavies” (drilling cuttings e.g.) settle fairly easily.

How hydrocyclone works in desander and desilter

hydrocyclone

A hydrocyclone has two exits on the axis: the smaller on the bottom (underflow or reject) and larger at the top (overflow or accept). The underflow is generally the denser or thicker fraction, while the overflow is the lighter or more fluid fraction.

GN Solids Control provide hydrocyclone  separator for oil gas drilling mud industry and mining slurry separation,HDD mud recycling and more.

Firstly, we should know where is the solids from.

HA, when we drilling, the drilling mud take them out.

What is the mud’s function?

OK, so we get one more question, what the mud do in solids control system, i.e. what is the mud’s function. You can see How Drilling Mud Work In Solids Control System And Drilling Rig that I write before. I will list the main function again:

Remove cuttings from well
Suspend and release cuttings
Control formation pressures
Seal permeable formations
Maintain wellbore stability
Minimizing formation damage
Cool, lubricate, and support the bit and drilling assembly
Transmit hydraulic energy to tools and bit
Ensure adequate formation evaluation
Control corrosion (in acceptable level)
Facilitate cementing and completion

And then we can find the answer: We must get high quality drilling mud to ensure the drilling process.

COST of drilling mud and environment friendship

But why don’t we produce some new mud, here we go, I have the same question.

The answer is only one word—COST. The cost of produce new drilling mud is higher than this, it is just an economic choice.

Removing solids from drilling mud limit the cost and what’s more important, it’s good to the environment.

Drilling mud trip tank definition

Drilling mud trip tank is a small mud tank with a capacity of 10 to 15 barrels, usually with 1-barrel or H-barrel

Mud Trip tank

divisions, used to ascertain the amount of mud necessary to keep the wellbore  full with the exact amount of mud that is displaced by drill pipe. When the bit comes out of the hole, a volume of mud equal to that which the drill pipe occupied while in the hole must be pumped into the hole to replace the pipe. When the bit goes back in the hole, the drill pipe displaces a certain amount of mud, and a trip tank can be used again to keep track of this volume.

Shaker mud tank

The mud tank adjacent to the shake shaker, usually the first tank in to which mud flows after returning from the hole. Also called a shaker pit.

GN manufacture not only full package mud system,but also independent components and equipments for solids control,like mud mixing tank,mud agitators,trip tank,trip pump etc.
