solid control system

DC Drilling Mud Solids Control System can realize the storage and mixture of drilling fluid, remove the harmful solid phase, maintain the performance of drilling fluid, content the demand in the special situation of drilling fluid cycle, weight addition, shearing and trouble removal, and can increase the drilling operation efficiency and safety effectively.

Drilling fluid centrifuge for Unweighted and Weighted Drilling Fluids.

Drilling fluid centrofuge is the 4 stage equipment of the oil& gas drilling fluid circulating system. The centrifuge suck the mud from the compartment receiving the discharge from the desilters and mud cleaners, and the returned stream is directed to the next compartment downstream.

DCLW centrifuges can be used in Unweighted Drilling Fluids and Weighted Drilling Fluids. Following is the maters of the centrifuge used in the different materials.

decanter centrifuges

When centrifuging the unweighted drilling mud, keep in mind the following:  the centrifuge with High G force as the solids loads are low. Adjust the weir to a deep pool to maximized solids separation. Control a smaller mud feed rate to increase residence time Operate centrifuges in parallel, not in series if multiple centrifuges are required.

With the unavoidably higher solids content of weighted mud, the increase of gel strengths and viscosity, as well as the degradation of ? quality associated with the diminution of particle size with time, can become a serious problem. The problem is caused by the increasing concentration of colloidal and near-colloidal particles that are  to be separated from the base. Centrifuges are used to selectively remove these solids.

With high solids content of weighted fluids, torque is a problem when processing it, the following is some advice when operating the centrifuges. Increase pond depth. Reduce in rpm or run a higher conveyor differential. Process the mud at a reduced feed rate Centrifuges.

The professional mud tank designed for Oilfield

A mud tank is a large storage container used to hold reserves of drilling fluid, also known as drilling mud, for a drill rig. Drilling fluid is used to reduce friction on drill components to allow them to work harder and faster with less risk of breaking down.

Now, In DC workshop has a professional designed mud tank for oilfield. Numerous companies manufacture and refurbish mud tanks of various shapes and sizes for industrial use, and contractors who specialize in cleaning tanks and other drilling equipment are also available. The cost for tanks and associated services varies widely, especially when custom designs are involved.

mud tank

Mud tanks are the base of solids control equipment. Mud Tanks for solids control system is divided into Square tank and Cone-shaped tank according to the shape of tank bottom. The main function of mud tank is storage, because the worked drilling fluids must stored to the next seperation or to the next recyclation, or to be reused.

What functions of hydrocyclone in solid control system

Hydrocyclones are simple mechanical devices, with out moving parts, designed to speed up the settling process. Feed pressure is transformed into centrifugal force inside the cyclone or cone to accelerate particle settling in accordance with Stoke’s Law #1. In essence, a cyclone is a miniature settling pit which alloys very rapid settling of solids under controlled conditions.

hydrocyclone

Hydrocyclones have become important in solid control systems because of their ability to efficiently remove particles smaller than the finest mesh screens. They are also uncomplicated devices, which make them easy to use and maintain.

Design features of cyclones units vary widely according to the size. The cyclones are made of composite materials and hold up to wear quite well. The size of cyclones in use varies from 12” down to 2”. The measurement refers to the inside diameter of the largest, cylinders section of the cyclone. In general, but not always, the larger the cone, the larger the cut point and the greater the thru put. Refer to the figures below:

hydrocyclones

Hydrocyclones are another important line of defense in the battle against the removal of solids from your drilling fluid.

Re-placed the order of 3 sets vacuum degasser for my Russian cooperator

This morning, DC machinery delivery 3 sets ZCQ270 vacuum degasser to our old cooperator in Russian. The 3 sets vacuum degasser are respectively used in 3 sets drill rig site in different areas.

Vacuum degasser can wipe off the invaded gas from drilling mud quickly, restore drilling mud proportion, keep mud viscosity performance and improve the quality of drilling fluid.

degassing equipment

Vacuum degasser uses vacuum to release free and dissolved gas in water, and then discharge them through the automatic exhaust valve system. At the same time, the degassed water will be injected into system.  This low gas content water is not saturated with highly absorbent for gas, it will absorb the gas in the system to achieve the gas water balance. Vacuum degassing machine repeats this cycle every 20~30 seconds. This movement in circles removes all the gas in the system.

vacuum degasser

Vacuum degasser produced by DC Machinery is suitable for various supporting of drilling mud solids control system, it plays an important role in restoring drilling mud performance, and can also be an agitator with big power.

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.
