The most important method to remove solid is the vibrating screen

One method of removing solids from drilling mud is to pass the mud over the surface of a vibrating screen. Particles smaller than the openings in the screen pass through the holes of the screen along with the liquid phase of the mud. Particles too large to pass through the screen are thereby separated from the mud for disposal.

Screening Surface. Screening surfaces used in solids control equipment are generally made of woven wire screen cloth, in many different sizes and shapes. The following characteristics of screen cloth are important in solids applications.

screens

Screens may be constructed with one or more LAYERS. NON-LAYERED screens have a single screen cloth mounted in a screen panel. These screens will have openings that are regular in size and shape. LAYERED screens have two or more screen cloths, usually of different mesh, mounted in a screen panel. These screens will have openings that vary greatly in size & shape.

Mesh is defined as the number of openings per linear inch. Mesh, can be measured by starting at the center of one wire and counting the number of openings to a point one inch away.

SIZE OF OPENING is the distance between wires in the shaker screen cloth & is usually measured in fractions of an inch or microns. Screens of the same mesh may have different sized openings depending on the diameter of the wire used to weave the screen cloth.

shaker screen

The smaller the diameter of the wire results in larger shaker screen openings allowing larger particles to pass through the screen. The larger the diameter of the wire, the smaller the particles that will pass through the screen Remember: It is the size of the opening in a screen not the mesh count that determines the size of the particles separated by the screen.

PERCENT OF OPEN AREA: is the amount of the screen surface, which is not blocked by wire. The greater the wire diameter of a given mesh screen, the less open space between the wires. For example; a 4 mesh screen made of thin wire has a greater percent of opening than a 4 mesh screen made of thick wire.

The open area of a non-layered, square or oblong mesh can be calculated and should be available from your screen supplier.

Linear motion shale shaker and mud cleaner leave DC factory

Drilling fluid shale shaker is used in the drilling mud purification system 1 level solid control equipment.Drilling shale shaker is mainly used to get rid of the big solids particles in the mud from the wellhead back to the ground surface, it enables the mud to be reutilized.

Mud cleaner is the second stage mud equipment of solid control system. Mud Cleaner is a desilter unit that is used to remove sand particles which have a grain size of 20 microns or less.

shale shaker

All those solids that are not removed by a shale shaker are removed by a desander. Further the smaller size of granules lesser than 20 microns are removed by the desilter. Mud cleaners do not have any moving parts and the removal of sand and silt from the drilling fluid is done by the centrifugal force on the device.

This times DC Solid control shipped many sets linear motion shale shaker and mud cleaner to abroad. Meanwhile, The clients ordered a ZJ4000 solid control system now, and we will delivering it in next month. So please notice my blog, I will updating it once we delivery the solid control system.

The Most Important Oilfield Mud Equipment- shale shaker

Oilfield drilling is a complex process involving multiple pieces of equipment to ensure proper extraction, cleaning, and safety. While the variety of oilfield equipment used can at first be overwhelming, we’ve listed out the most important pieces to become familiar with. It plays an important role in reducing costs, accidents, and environmental impact.

shale shaker 1

The most important part of the solids control/separation system on a rig, shale shakers separate the “cuttings” (large solids) from the “mud” (drilling fluids). After the mud is separated, it is used to keep the drill bit cool.

shale shaker2

Ideally, these fluids can be reused more than once. This separation before the disposal of cuttings helps reduce drilling costs and environmental impact. Proper controlling of drilling fluids is correlated directly to the efficiency of all other downstream controlling equipment later in the process.

In order to supply the excellent shale shaker with high screening accuracy, low-energy and no dust pollution, DC Machinery controls quality strictly in each procedure.

Proper screen is important for shale shaker using

Shale shakers are devices that remove drill cuttings from the drilling fluid that is used for boring holes into the earth. Controlling the solids in drilling fluid is an important component of the cost of drilling, so research into improved shale shaker design is ongoing.

Shale shakers typically consist of large, flat sheets of wire mesh screens or sieves of various mesh sizes that shake or vibrate the drill cuttings, commonly shale, across and off of the screens as the drilling fluid (mud) flows through them and back into the drilling fluid system.

drilling fluid shale shaker

This separates the solid drill cuttings from the fluid so that it can be recirculated back down the wellbore. In oilfield industry, linear motion shale shakers are widely used.

shale shaker

Screen panels play a major role by removing particles larger than the mesh size. Screen selection is critical since shaking is the primary stage in the removal of solids.

Improper screen selection can lead to de-blinding, loss of drilling fluids, premature pump part failures, overloading of other solids removal equipment within the mud systems, decreased service life , reduced flow rate capacity, and serious problems in the wellbore.

DC models drilling fluid centrifuge in drilling site

Drilling fluid centrifuge is an important part of solid control system. DC Solid control sold 50 more sets centrifuge to different countries used for different industries.

Drilling rig centrifuges have got large development on both structure and functions. Especially there are many manufacturers design centrifuges according to drilling mud features or property. Then the centrifuge become many models and types used in various drilling projects.

drilling fluid centrifuge

Decanters are equipped with either fixed or variable back drive. The scrolling speed -(relative conveyor speed) can be changed in a matter of seconds by operations of a simple control switch. The optimum scowling speed is selected in each case according to solids load, required separation efficiency and required underflow density.

Actually, in drilling rig solids control system centrifuge is the most complicated one. It is rather difficult for operator get leagal operation, etc. However, in long term its important position is following shale shaker subsequently.

Using Importance Of Mud cleaners For Unweighted Drilling Fluids

The purpose of the mud cleaner is to remove drilled solids larger than barite. Mud cleaner could be useful cleaning facility at many filed of mud management.

The principal use of mud cleaners has always been the removal of drilled solids larger than barite. Sufficient drilling fluid bypasses shale shakers so that even with 74-micron (API 200) screens on the shakers, many drilled solids are removed from a weighted drilling fluid.

mud cleaner

Using of mud cleaners is the removal of drilled solids from unweighted drilling fluids with a very expensive liquid phase—such as the initial application with the potassium chloride drilling fluid.

In this case, the underflow from desilters is screened to remove solids larger than the screen opening. Solids and liquids pass through the screen and remain in the system. This is beneficial for nonaqueous drilling fluids as well as saline water–base drilling fluids.
