Why Choose Coarse Flow Line Shaker Screens in drilling rigs

Most drilling rigs operate their primary flow line shakers with screens that are far too coarse (to achieve meaningful solids control. Many factors cause this selection, and we now find ourselves in a viscous industrial cycle.

shaker screen

To cut costs, drilling rig operators use coarse screens that last longer and require significantly less personnel attention. Further, coarse screens minimize the risks of whole mud losses when drilling fluid circulation rates are high. However, the risk of whole mud losses would be significantly reduced, if a sufficient number of shakers, creating sufficient surface area, were installed.

By using coarse screens, drilling rig operators have become more reliant on solids control service companies to maintain the drilling fluid performance and ultimately the rig’s rate of penetration.

Most drilling rig hands do not understand that usually, the wetter the solids discharge from the flow line shakers, the higher quality solids cut is being achieved. This is especially the case when drilling through reactive hydrophilic soils.

Trial order of corrugated pyramid shaker screen from Nigeria

Trial order of pyramid shaker screen will flying to Nigeria this morning. This is only a simple which we send to them. The use of corrugated pyramid screens on a dryer in second stage mud and cuttings cleaning helped recover a large volume of oil-based drilling mud to save more than $60,000 in mud costs.

DC Machinery Company has again revolutionized screening technology with the introduction of the patented Pyramid (PMD) and Pyramid Plus (PMD+) screens. This revolutionary three dimensional screen design offers the benefits of traditional flat screens while adding a significant increase in useable screen area; allowing for a 70% increase in fluid handling capacity.

img_0367

Benefits of Pyramid Screens compare with the flat screens:

1. Increased Shaker Capacity—Pyramid and Pyramid Plus screens increase the total amount of useable screen area by 50% to 125%.
2. Screen Finer Faster—Utilizing Pyramid or Pyramid Plus screens enables rigs to screen 2 to 3 mesh sizes finer than traditional perforated plate panels. This maximizes solids removal capacities.
3. Makes Fine Separations—Pyramid and Pyramid Plus screens are capable of making separations as fine as 43 microns.
4. Easily Repaired—The Pyramid screen design lends itself to easy field repair with RTV products.

Pyramid screens provide an easy, cost effective increase in shaker performance. Designed with the latest technology, Pyramid screens allow rigs to screen finer earlier in the drilling process, thus significantly reducing mud and disposal costs.

Shale shakers “heart and soul”- shaker screen

Basically, a screen acts as a “go/no-go” gauge: Either a particle is small enough to pass through the screen or it is not. Screening surfaces used in solids control equipment are generally made of multi-layered woven wire screen cloth and are the “heart and soul” of the shaker.

Fundamentally, the quality of a shaker is defined by the quality of screens it utilizes. When selecting a solids control system it is important that the quality of the screen manufacturing and level of experience by the in manufacturing screens is considered.

If the system is appropriately set up with a scalping system and a fine shaker screen system, the scalping screens must be sized just coarse enough to ensure that drilling fluid does not sheet off the shaker (i.e. whole mud losses). This happens when the scalping screen is too fine to allow the drilling fluid to pass into the solids control system’s dirty tank.

shaker-screen

Typical scalping screen configurations for HDD applications range from 50 mesh (API 50) to 120 mesh (API 100). Typical fine screen configurations range from 160 (API 120) to 200 mesh (API 170). The API 13C classification is gaining traction in the HDD industry as more contractors focus on the micron cut point they are trying to achieve in their fluid.

Relative to the use of shaker screens, it is the size of the screen openings, not the mesh count that determines the size of the particles separated by the screen. It is because of this fact that HDD system users should compare and specify screens based on their API 13C designation.

Two types arrangement of the installation screen

Screen installation arrangement has two types of tandem and parallel.

  1. Tandem type installation screen

Tandem installing screen is that the drilling fluid must pass through two or more than two screens with decreasing pore size which are separated from each other by some distance. This arrangement has the advantages of the upper screen firstly screen out the large size ofcuttings, it can protect the more fine screen underlying effectively, especially in fast drilling. And when the solid content of the drilling fluid is increased, lower layer screen will not be overloaded; And the shortcomings of this kind of sieve are that it is not easy to observe the lower layer screen, if the replacement is not timely after being damaged, it will influence the treatment effect of drilling fluid.

Coupled with the inconvenient replacement, only one layer of screen is used in some crew.

  1. Parallel type installation screen.

Parallel installation screen refers to two or more than two meshes lap together and form a long screen. This type of instalation has the advantages of  increasing the treatment capacity and will not let the drilling fluid run away(because of the long screen); When a section of screen is broken, only the broken section needs to be changed. This can save the cost of screen and the replacement is more convenient. The disadvantage is that the structure is complex and the weight of the whole machine is increased.

The steel frame screen and the combination of 2 to 3 layers of stainless steel mesh in the framework of the constitution of the type of screen features are as follows:

(1) The screen nets with different mesh size, accurate and reasonable collocation and the screening effect is more careful.

(2) High strength steel frame and the support bar, and Chang appropriately tight mesh, forming a reliable overall, greatly enhanced the screen can withstand flow, strength and service life. Fast tensioning device to make the screen wedge installation is more convenient, saves the replacement time.

(3) The screen cloth is divided into a plurality of independent small mesh surface, which can prevent the partial breakage and excessive expansion. At the same time to be equipped with a special rubber plug repair damaged, which can save time, and reduce cost.

Requirements of screen surface of shaker screen

The basic requirements of the drilling process for the shale shaker is not only recover drilling fluid as much as possible, but also remove harmful solid phase as much as possible. This requires that: Firstly, in order to improve the throughput and recycle drilling fluid, solids on the surface of the screen should be drained away as soon as possible; Secondly, the solid particles in the sieve surface is best not to make sliding movement in order to reduce screen wear; Thirdly, the critical particles that stuck in the mesh hole should be easily through the sieve hole or jump off the screen surface.

shaker screen

In order to meet the above requirements, shale shaker should let the solid particles do throwing motion on  the sieve surface. But tangential acceleration along the screen surface of particles not need to be too big, because over large screen normal acceleration will accelerate the the impact to screen when particles falling down, so that part of the cuttings group was crushed, and increase the screening rate, it is not easy to recycle liquid phase.

So as long as the particles can overcome the adhesion force, firction and surface tension  between itself and the drilling fluid and to ensure drilling liquid go through the screen smoothly. At the same time, the shorter the time that the solids phase stay on the the screen is, and the less the beat frequency is, so the smaller of the probability of screening is.
