Drilling fluid decanting centrifuge used for recovery barite to remove small solid particles, reduce the mud solid content, to ensure the performance of the drilling fluid. And DC production drilling fluid centrifuge has high purification efficiency, convenient adjustment and easy maintenance. The DCLW360-1200VFD centrifuge is a frequency conversion which rotary speed can be adjusted by the control box, and its max treating capacity can get to 40m3/h.

The domestic customer is focus on petroleum drilling and want to purchase the stock equipment,  so they and their drilling engineer visit our factory and sign the contract. The customers are satisfied with our high quality equipment and professional solid control design technology.

DC Solids Control attend CIPPE ( China International Petroleum & Petrochemical Technology & Equipment Exhibition ) begain last year in order to link with international market . As China manufacturer, DC focus on international market and domestic high-end market, to serve all over the world customer with high quality and excellent technology products.

This year we have a plan to attend to Dubai Petroleum equipment and technology exhibition on Nov. DC solid control will expand the occupation rate of international market. Except for building supply relationship with overseas national oil service company and we will establish overseas branches at oil rich countries and areas to support local business development.

Shear pump is base on the centrifugal pump theory, according improvement and developed the new, high efficiency centrifugal pump, it is the equipment which is rapid configuration and process drilling fluid in solid control equipment matching system, the main use is shearing polymer clay when allocate drilling fluid, it can effective mix and fully hydrated all the materials in drilling fluid, save the drilling materials, shorten the time of drilling fluid allocation, provide good performance drilling fluid for drilling process.

Shear pump transport the drilling fluid with small particles, working condition is very bad, when the shaft seal of shear pump is leakage, it can causes the efficiency of pump is decrease and waste drilling fluid, also can pollute environment. So high efficiency and reasonable seal quality is the key of ensure shear pump normal and safety operate.

Structure

The pump is single stage and single section of cantilever type centrifuge, it provides shearing function with guide liquid type, centrifugal combination impeller and shearing plate. The special structure liquid end impact shearing plate, make it high speed shear, in order to complete agitate to foluid.

Characteristic

The shear pump can mix and hydrate fully the materials which were added into the mud, to save the usage of mud materials, shorten the mix time and to supply good- performance mud for the drilling. The shear pump can increase the hydration degree of the particles, quicken the attenuation and hydration of the polymer and offer a high output volume and lift to match the requirement of preparation and mud.

Drilling fluid shale shaker is the first class of drilling fluid solid control equipment, and it is used in the whole drilling well process. The rang of eliminate the solid phase particles is decided by the type of screen, the throughput is related with the screen specification. The screen mesh is bigger, the throughput is smaller, the particles are removed are smaller, the removed particles are greater amount. From the production, hoping use the fine mesh screen, from the economic, the using time of the fine mesh screen is short, so the screen needs overall consideration.

The exploitation and popularize of the mechanical laminate screen and the chemical splice screen effectively improve the fine mesh life times and the purification level of drilling fluid shale shakers.

There are many combination types of the cascade screen, usually the sublayer have 12meshes, the upper use the 30, 40, 60 meshes. The drilling fluid shale shakers don’t use the 80 and more than 80 meshes screen, because the screen mesh is greater and the through sieve rate is lower, led to the screen life time is short.

In order to drilling fluid shale shakers are matching with the drilling machine, we must consider the maximum discharge of the drilling pump and the number of drilling cuttings which are produced in the drilling process, as Qscreen>Qpump+Qcuttings

Qscreen—the throughput of the drilling fluid shale shakers, L/S: Qpump—the maximum discharge of the drilling pump, L/S;q Qcuttings—the cuttings volume in the drilling well.

Because the different drilling machine have the different rotation speed, the drilling cuttings in the unit time to the pump displacement is small, drilling fluid shale shakers use the duplex or trigeminy. So Q screen=Qpump n

To the duplex shale shakers, when replace the screen, must have a single screen stop working, the other single screen must can dispose the whole drilling fluid, so to the duplex screen, n=2. When the trigrminy shale shaker works, must have two single screen dispose the whole drilling fluid, so to the trigrminy, n=3/2.

Now the throughput of the drilling fluid single screen is 40-50L/s.In conclusion, we can obtain the shale shakes’ using methods. In the early day drilling, the diameter of the well is big, the pump discharge is big, the mechanical drilling speed is high, producing a lot of big particles solid phase, the drilling cuttings volume is big, we should use the small mesh screen to dispose the drilling fluid. Following the increase of the drilling depth , the diameter of the well is small, the pump discharge is small, the drilling machine speed is low, producing a lot of small particles solid phase, the drilling cuttings volume is small, we should use the bigger mesh screen to dispose the drilling fluid.

According the function of each components of drilling fluid solid control system put forward the reasons why choose this equipments, discussing the general arrangement methods of drilling fluid solid control system.

The function of solid control equipment

Following the development of drilling well technology, the effect of drilling fluid solid control system to the drilling well working is more bigger, there are all kinds of solid control systems, no matter the type of solid control how to changes, its basic function can’t be changed, it rely on the mechanical clear device and drilling fluid storage tanks and other auxiliary equipment to work together to complete the basic effect.

In drilling well, drilling head, crushing, grinding the ground, make the rock breakages, formation the different size of drilling cuttings, the size is between 2 and 2×10³μm. The single clear equipment remove rang of the solid phase particles is small, so depending on a device can’t reach the purpose of maximum clear the solid phase.

The different equipment can remove the different size solid phase particles. To guarantee carrying the drilling cuttings to the ground, drilling fluid must has the enough up return speed. So must accord the size of the well and the drilling machine to decide the displacement of drilling pump.
