Derrick pyramid screen replacement for oilfield drilling fluids

When it comes to a solid control system on any type of drilling equipment, the shale shaker is arguably the most important pieces of equipment. With drilling fluid being so important to maintaining drill performance, being able to utilize fluid efficiently is crucial. A shale shaker is what separates any drilling liquid, commonly referred to as mud, from solids, also known as cuttings. On a shale shaker, one of the most important components is the shale shaker screen. The shale shaker screen is actually what separates liquids from solids so having the correct screen can determine how effective drilling equipment operates.

Shale shaker screens 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 shaker design is ongoing. Shale Shaker Screen Design Shale shaker screen typically consist of large, flat sheets of wire mesh or wire cloth 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. 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. 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[clarification needed], 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. Two design changes have been made to extend the economic limit of fine-screen operation: (1) a coarse backing screen, which protects the fine screen from being damaged, extends life, and provides additional support for heavy solids loading. (2) tensioned cloth bonded to a screen panel.  We are the leading shale shaker screen manufacturer located in China. Our company set the standard for the shale shaker screen manufacturing.
