800pcs Derrick Hyperpool shaker screens shipped to Australia

Hyperpool shaker screen replacement from DC is right fit panel for Derrick Hyper shaker. It is the corrugated screen panels with larger filtration area. Now we have 800pcs finished the production and prepare to ship to Australia.

Hyperpool shaker screen is designed as PMD and PMD+ screen panel. The more larger or extra large area benefit much on shale shaker performance and totally save the drilling cost for many clients. Such shaker screen is designed with one handle, while another side is configured with a triangle like breach in the middle

Hyperpool shaker screen dimension is about 22.5″x42.1″. The PMD Hyperpool will high 1″, while the PMD plus Hyperpool screen will high about 1.5″. According to our present order and inquires, we found major users prefer the pyramid but not plus panel

The hyperpool shaker screens sizes are commonly available from API 40 to API270. And rarely clients will ask special mesh size, such as API 325, API400. If you have interest with it please feel free to contact us.

What screens’ factors impacting shale shaker working performance

Shaker screen is the critical parts for a shale shaker and it defens the working efficiency of shale shakers. Do you know what factors will impacting shale shakers working performance ?

Based on API RP13C, the shaker screen panel features including the cut point, the conductance, the non blanked area. What is the actual impact or issue? Cut point means under D100, the mesh size of solids separated out of materials. Such as 300microns, 63microns, and so on. The conductance is an important issue to define the screens filtration efficiency. And the non blanked area is another reference of effective filtration area.

If consider the shaker screens thoroughly on many different aspects, there are features of screen form, screen quality, screen appearance, screen fitness or compatibility, shaker screen weight, and so on.

DC Solid control is a professional manufacturer of all brands shaker screens. During manufacture, we’ll do strict inspection after each procedure. Such as screen cutting, frame welding, composite frame injection, vulcanization, and so on. Furthermore, DC screen configuration has been tested per API RP13C with conform result

Why shaker screen has screen blinding

Screen blinding occurs when grains of solids being screened lodge in a screen hole. This often occurs when drilling fine sands, such as in the gulf of mexico. The following sequence is often observed during screen blinding:

1. When a new screen is installed, the circulation drilling fluid falls through the screen in a short distance.

2. After a time, the fluid endpoint travels to the end of the shaker.

3. Once this occurs, the screens are changed to eliminate the rapid discharge of drilling mud off the end of the shaker.

4. After the screens have been washed, fine grains of sand that are lodged in the screen surface can be observed. The surface of the screen will resemble fine sandpaper because of the sand particles lodged in the openings.

 

Most eshaker screenvery screen used in the oil field is blinded to some extent by the time it needs replacing. For this reason, when the same screen size is reinstalled, the fluid falls through the screen closer to the feed.

One common solution to screen blinding is to change to a finer or coarser screen than the one being blinded. This tactic is successful if the sand that is being drilled has a narrow size distribution.

Another solution is to change to a rectangular screen, although rectangular screens can also blind with multiple grains of sand. Unfortunately, the process of finding a screen size that will not blind is expensive.

In the late 1970s, the layered screen was introduced to avoid screen blinding. This hook strip screen was mounted on a downholl sloping, unbalanced elliptical motion shale shaker vibrating at 3600rpm. The two fine layers of screening cloth, supported at 4 inch  intervals, tended to dislodge fine grains of sand and would only blind about 25% in severe laboratory tests, leaving 75% of the screen unblinded. The non-blinding feature is assumed to be the result of the deceleration of the two screens. The wire diameter is in the range of 0.002 inch and the opening size are in the range of 0.004 inch.

High quality Shaker Screen in oilfield

The combination property of drilling fluid shale shaker is reflected by sieve size, service life, and the treating capacity, moreover the above-mentioned situations are bound up with the structure and performance of screen. Screen is the important part in sieving, and is a kind of easy consumable in drilling.

Therefore we should pay attention to maintain shaker screen. Before every shut off, the shaker should run without any medium for 5-10 minutes, at the same time, use clean water to flush screen clean.  There should be not much sediment on shaker frame and shaker screen.

Choose suitable mesh of shaker screen is also important. Usually, when the shale shaker is first stage solids control equipment the shaker screen can be 30-100mesh. When the shale shaker is a part of desander or desilter, the shaker screen  will be 80-200mesh. Simply speaking, if the mesh number is larger, the sieve size is smaller, the handling capacity will be reduced at the same time. Of course, the selection is relative with drilling mud property and our working condition at the drilling job site.

The following is the common used shaker screens in oilfield drilling.
