The selectivity solid phase control technology 

Application selectivity solid phase control technology, the returned drilling fluid from well mouth through high efficiency screened divided into big grain wet drilling cuttings and sieving fluid, which separated the three class solid phase through classification filter separator, from thick to fine successively is thick drilling cuttings(74~35 µm)aggravate solid phase(35~15 µm)and fine drilling cuttings (2~15 µm), after the aggravate solid phase separated by separator return into drilling fluid system, the coarse and fine drilling cuttings excretion. It can eliminate more harmful solid phase, especially the diameter particles lower than aggravate solid phase harmful solid particles, can improve drilling machine speed, decrease drilling fluid viscosity and dilution water and decrease drilling fluid volume.

Drilling cuttings in –line treatment technology: 

We only value drilling fluid treatment past, but lose sight of the treat to drilling cuttings, drilling cuttings directly discharge into mud pit. Every well all need a mud pit, the area should exceed 500m2. According to treat the wed drilling cutting in-line, can divided into filtrate and dry drilling cuttings, filter returned to drilling fluid system, the dry drilling cuttings are placed in storage and transportation box, centralized processing and recycling used, according to drilling cuttings in-line treatment technology can make drilling cuttings and waste drilling fluid can’t drop on the ground in drilling field, can fully recover available drilling fluid and don’t use mud pit, it has the obvious e economic benefic and huge social benefit.

Drilling fluid recycle technology 

Usually the waste drilling fluid is 100-300m3 after a well drilled successfully. According to the homologous stratum characteristics and drilling fluid type to separate the waste, to the available drilling fluid proceed fully recycle use, can decrease drilling fluid gross, decrease emission load, the benefit is very obvious. Of course, the drilling fluid recycle need a set of processing measure, main including the improvement of drilling fluid performance, classification storage and reliable application.


Drilling fluid mud agitator is mainly keep uniformity of drilling fluid and made solid .Drilling fluid mud agitator is mainly keep uniformity of drilling fluid and made solid phase suspension, is the ongoing and reliability drilling mud solid control system. it is mainly used to mixed drilling fluid, in order to prevent drilling fluid solid phase particles precipitate in the tank type circulating system, make the performance of drilling fluid stabilize and mixing uniformity.

characteristics of drill mud agitator

Drilling mud agitator use the arc and cylinder reducer, the section is cylindrical turbine of circular arc , the tooth profile of turbine is round which is conjugate with worm.

Drilling mud agitator use the combination of reducer and explosion proof electric machine, it is easy to maintain, it adapts to the condition of field bad working environment.

The stirring intension of drilling mud agitator is strong, extensively affected and decrease the starting resistance.

The motor of drilling mud agitator place in a horizontal position, it is convenient to install and adjust.

The structure and working theory of drilling mud agitator

Structure: the device is mainly made of explosion proof electric machine, reducer, engine base and impeller components, reducer and motor, reducer and wave wheel are all connected with solid coupling. The wave is made of four impellers weld.

Working theory: The wave can make agitate fluid produce vortex motion and enhance the mixing effect. The tray caught in the middle of the blade can avoid the mud solid phase deposit on the round of lower impellers after stopping, such use can reduce the resistance moment of the sediment to impeller, it prevent burn motor when starting overload.

The installation and operation maintenance of drilling mud agitator

The mud agitator should be level lifted and smooth placed in the installation position, after adjust the coaxial degree is less than 0.39mm, the four M16 hole seats are welded in the tank and tightening the engine base, fixed bolts.

The rigid coupling of mud agitator must be installed the spring pad and strong reliable, otherwise it maybe cause the deflection of wave wheel and accelerated wear of reducer.

In the operation of mud agitator should not have abnormal sound, cassette and excess temperature or other conditions.

The fuel head of mud agitator reducer should be kept in the middle part of apparent oil window, it needs often complement enough lubrication. 

∑theory is put forward by Ambler in 1952, it is used to calculate the throughput of sedimentation centrifuge. The theory thinks that the liquid is according the characteristics of piston type to flow, the flow speed in the whole flow section is constant.

After drilling fluid enter into centrifugal drum, the liquid phase along the shaft of drum flow to overflow month to flow out. The solid particles follow the liquid shaft to flow, under the centrifugal force effect to precipitate which is along the radial, because the sedimentation rate of fine particles is slow, the time of precipitation to the wall of drum is long. If the quantity of admission mud is large, axial velocity is too fast, the residence time of fine particles is too short, the fine small particles along fluid overflow drum and it can’t be separated. So the throughput of sedimentation centrifuge should be interpreted as the desired separation of the smallest particles in drum, is not the biggest fluid flow is carried out of the drum following the separation liquid. So the certain separation factor of the same centrifuge to the different or same performance drilling fluid in the different requirements of separation, the throughput is different.The throughput ability of sedimentation centrifuge is depending on axial velocity and the particles centrifugal sedimentation speed.


The adaptability is good, the design is fully consider the solid control technology of oil drilling process with the special demand of the centrifugal, the main parts implement the specificity, adjustability and the optimization design.

The automaticity is high, the feeding, separation, unloading and other process under the high speed can continuous, automatically, the equipment control on-line with the microcomputer according to the user requirements ,realize the automation control of the technology.

Corrosion resistance, the drum, propellers, enclosure and the material contact components are all use the high quality stainless steel,  the corrosion resistance and rusting resistance is strong,.

The safety of device is complete and reliable, the centrifugal installed the temperature sensor and shock sensor, in the working if the temperature and vibration is abnormal or exceed the limit, it can active the gas protection system, to prevent the machine is damaged or bring the accident, the electronic control install the protection mechanism, to guarantee the safe use of the machine.

Based on the oil field tests and compared with other shale shake types, balanced elliptical motion technology can consistently provide gentle rolling motion, better solids removal and fluid circulation, less, screen wear. This paper discussed the latest technology in shake shaker, introduced the theory, stricture and performance of the balanced elliptical motion shale shaker.

Although the popular shale shaker is linear motion shale shaker at home and abroad, but looking from the theory and practice, linear motion shale shaker is not the best choose. So areas of abroad allocate the scraper before the shale shaker to dispose the mud.

The balanced elliptical motion shale shaker is more difficult to design than linear motion shale shaker, but following the development of technology and the maturity of the vibration motor technology, design some new balanced elliptical shale shaker.

BEM-3 shale shaker

SWACO company import the SWECO patent technology, use the eccentric block which is slant with the sifter, produce continuation and the same direction elliptical motion, in order to increase the separation effect. In theory, to drilling cuttings screen and dry, the balanced motion is the best choose. Because when solid particles roll along with screen surface, increase the contact area, so increase screening ability. Otherwise, in the same cast angle and amplitude, each unit retention time of balance elliptical shale shaker is longer than linear motions shale shaker.

BEM-600 shale shaker


BEM-600 shale shaker is the second generation shale shaker of SWACO, the product use the balanced elliptical patent technology. Tests show that, compared with other type shale shakers, it can keep the soft movement locus, has the best ability of remove drilling cuttings, it also can improve drilling fluid recovery, Decrease the screen wear. Besides, it cover area is small, the whole stainless steel structure, double-deck reel, the pneumatic structure is steady. So BEM-600 shale shaker has the best wipe method, greater throughput, more quick and more safety method of replace screen and drilling fluid recovery is more efficiency.


MONGOOSE double motion shale shaker

The double motion can form linear motion and balanced elliptical motion in one shale shake. SWACO company combine the balanced elliptical technology and linear motion technology to creatively produce the double motion locus shale shaker. The double motion function and special device, make MONGOOSE shale shaker can adapt to any land and offshore drilling condition,

VSM300 shale shaker

VSM300 shake shaker use multilayer screens, as the minimum screening area realize the biggest screening area. The up screen can protect the down more fine screen, the total area of screen is 5.6m2. When operation, only press the exciting force, the shale shaker can produce 4,6,8 the difference exciting force, so when operation, it need not stop shale shaker, we can also change the solid phase transportation rate, flow characteristic and phase quantity.


Compared with linear motion shale shaker, balanced elliptical shale shaker has the good adaptability, especially to fragile, slime stratum, Its advantage extrude. If reasonable collocate the two types shale shakers, we can obtain the best effect.
