Shale shaker is used in the first phase of drilling purification in petroleum exploration and exploitation. Two styles are avaiable; Linear motion shale shaker and balanced ellipse motion shale shaker.

The linear motion shale shaker uses two motors vibrate in-phase for separation. The electric vibrator and the electric equipment in the electric control system are imported explosion proof appliances.

The screen area is big, the higher capacity and the larger screening efficiency. The linear motion shale shaker track quickens the discard and improves screen efficiency. The basket can be adjusted to different angles tocope with different environments and drilling liquid conditions. The screen is durable and easy to install and maintain.

Ellipse shale shaker is the earliest shale shaker produced by China. The basic structure is the motor through the triangular belt to drive the screen box exciter rotate produce the vibration. This kind of shale shaker mainly made of screen box assembly, drilling fluid inlet groove, pedestal and adhesive tape cover.

The ellipse shale shaker service our country drilling project is about 20 years, because of its elastic vibrator design is science make the shale shaker start and stop is smooth and steady, with the big exciting force, large throwing index and the greater drilling fluid capacity.

As we know M-I Swaco is a word famous brand of solid control. And M-I Swaco have the task to research and development the advanced shale shaker. Recent days they have a new invention which is the MD-3 shale shaker, now let me introduce you to the M-I Swaco MD-3 shale shaker.

M-I SWACO new-generation MD-3 triple-decker shale shaker offers an ideal combination of high efficiency, flexibility and space optimization. The MD-3 shale shaker is unique in that it can adapt quickly as drilling conditions and cuttings volumes change.

M-I SWACO 1

Changing drilling conditions require immediate and flexible solids-control solutions. At the same time, ever-tightening environmental restrictions demand up-to-the- minute compliance. There’s also the matter of high drilling costs and the need to recover expensive base fluids. In addition, offshore and some onshore locations have limited space available demanding technologies be as compact as possible.

M-I SWACO

The M-I SWACO MD-3 shale shaker meets all those requirements and more. The advanced MD-3 shaker delivers in a small footprint, a high-efficiency solids-control option adaptable to changing drilling conditions. The highly efficient solids removal capacity of the MD-3 shaker translates to lower waste volumes, costs and downtime. What’s more, by generating drier cuttings at reduced volumes, the MD-3 shaker cuts your environmental footprint and associated coats.

This is the new type shale shaker, believe DC Solid control can research the most advance equipment to replace it, and DC Solid control will be the leader in word drilling industry.

Shale shaker is widely used in many fields. The common shale shaker is linear motion shale shake and balanced ellipse shale shaker. But the only two types shale shaker have already can’t meet users’ requirements. Different field should use different types of shale shaker, but if in the same field need use linear motion or balanced ellipse motion shale shaker at the same time. One set shale shaker can’t meet the requirements.

So according to the needs, Mi-swaco produced a shale shaker which is linear motion and ellipse motion combination. We call it Mongoose PRO shale shake or dual motion shale shaker.

SONY DSC

The mongoose shale shaker has three vibration motors to control the vibrating model. When we need linear motion we can start two motors, if we need ellipse motion we can start three motors. It has a control cabinet can switch the linear motion or ellipse motion.

Operators can change the type of motion required to either handle high volume or produce dryer cuttings, as drilling conditions dictate. With the MONGOOSE PRO shale shaker, nonproductive time lost to changing out shakers to meet drilling conditions is no longer an issue.

The MONGOOSE PRO shale shaker, the latest upgrade to the MONGOOSE line of shale shakers, outperformed an earlier generation shaker in both flow capacity and cuttings discard rates while maintaining the same cuttings dryness.

In order to prevent the innerstress is appeared from welding don’t allow weld screen box and any auxiliary parts.

We should adopt these steps when weld shale shaker

Drilling 6mm hole in one end of flaw in order to prevent flaw extend.

Using round shovel spade groove along two sides of flaw.

Firstly preheat about 60℃ using 3mm diameter welding electrode to prevent any slag inclusions and bite meat condition.

Rubdown the protuberant electrode and weld the stiffening plate.

If id needs weld in screen surface bracket beam, all welding line should be parallel with beam.

When use alternating current weld the screen box should connect the ground to prevent current conveyance the bearing. Otherwise it is easy to led bearing damage.

The cutting surface will produce stress when flame cut, so the any addition holes all advised drill.

Installation requirements of mud shale shaker

When knit drilling fluid shaker screen and screen bracket is matched special vibration attenuation rubber strip. In order to make screen can reach the longest service life, the rubber strip should placed in among of screen and bracket.

We should ensure the equal interval between two sides of shale shaker screen box and screen hook when replace knit screen, we should fix the centre and compact steel flat at first, then tension the plate to keep the stress of screen surface is uniformity. It is one of the premature failure reason If the connecting is not good, the stress is not enough or uneven.

Vibration exciter is the direction power source of compelling shale shaker produce desired trajectory, the different type of vibration exciter and installation model, it directly influenced the structure characteristics, working efficiency and using life of shale shaker.

The single-shaft vibration exciter is widely used in the early 1980, it is divided into self-centrifuge type and common vibration exciter the two types, following the development theory improve of drilling fluid shale shaker, the type of vibration had already replacement by double motor self synchronous vibration mode.

The drive belt wheel on the common vibration exciter must follow the screen box to vibrate in the work of shale shaker. This type of shale shaker is called common shale shaker, such as early NS-77screen, NS-80 screen. The structure of simple Single-shaft inertia shale shaker vibration exciter although is simple, but because pulley and vibrate, cause the centre pulley periodic change, make the drive belt elongation or shorten repeated, influenced using life time,Screen box movement is not stable.

The self-fixed centre vibration use the self-fixed centre shale shaker. when shale shaker works, the potation belt wheel of the exciter only do fixed-axis rotation, it is not following the screen box to vibrate. The shale shaker with the function is called the centre shale shaker, such as early 2YNS-D shale shaker, NS-821 shale shaker and ect.

In the process of drilling, the drilling cuttings are produced in the bottom well are carried to the ground by drilling fluid, drilling fluid shale shaker is the fastest, biggest and earliest solid control equipment which remove the drilling cuttings, it is the necessary the first process equipment. The engineering level of shale shaker is mainly reaction in the ability of throughput, the reasonable of working, the length of using life, operation and maintenance.

The situation of size of drilling fluid particles, content viscosity and the performance are non changed, the dynamic shear is bigger of drilling fluid solid phase particles, the take off resistance of solid phase particles, the migration speed of solid phase is getting smaller. The theoretical research of foreign drilling fluid shale shaker is fully realize it, drilling fluid flow out from the drilling separator, before enter into the shale shaker screen, setting a drilling fluid impact tank, preventing the drilling fluid directly impact the screen, maximum decrease the shear stress which the drilling fluid return from the well month, not only the stress of solid phase and the motion are reasonable, but also decrease the status of drilling fluid runs and emits and increase the throughput of the drilling fluid, extend using life of the screen.

In recent years, the domestic shale shaker has a great improve, especially in theoretical reach, such as the movement locus of shale shaker and the using life of shale shaker have already reach or approach the word advanced level. But the research in domestic shale shakers don’t attention the importance function of drilling fluid impact tank in shale shaker,  when we choose drilling fluid shale shakers, we must choose the structure shale shakers

In addition, because the material, processing technic, working accuracy and the matching use of the common equipment are different, make the products actually reach the technology performance has a great distinguish. So we choose drilling fluid shale shakers, we must detail know the material, processing technic, working accuracy and the matching use of common equipment instead of the show technical index to choose.

The importance of the screen

The combination property of the drilling fluid shale shaker reflect the sieve size is fine, using life is long and the throughput is big, this conditions are related to the structure and performance of the screen. The screen is a important part of screening task, it is the consumables in drilling fluid, the size of the hole determines the size of the solid phase particles are removed by the shale shaker. Because drilling fluid have corrosive, abrasive resistance and the high temperature,

The specification of the screen

The specification of the screen determines the sieve size, the sieve size is the size of the sieve pore which the particles can pass. Because the oilfield and the related industries learn from the foreign stander, so use the mesh representative the size of the sieve pores, it is said that the number of the sieve pores in one inch width.

For different drilling mud equipments manufacturer will hold their own model

In order to remove the smaller particles in drilling fluid, the material of the screen is the stainless steel wires of the heat treatment, the material of the ancillary shoring structure is steel plate, galvanized sheet, plastic board and ect.

shale shakers. Different type shale shaker will hold different features and superiority.

To develop both precise and accurate process control, DC conducted a battery of tests. These tests included; cure tests by varying time and temperature; bonding strength tests by testing the tensile strength of the cure screens through destructive testing; and chemical exposure tests by immersing a series of screens in chemicals characteristic of the oil & gas industry.
