Operational Recommendations of Applying Shale Shaker Screen

The shaker screen is equipped on the basket of shale shaker, with three or four pieces screen panels, while the screen basket is driven by two sets of vibration motors. Shaker screen may shear polymer bonded whilst move.
 
XI'AN, China - May 28, 2015 - PRLog -- In oil & gas drilling, shaker screens are used not only on shale shaker, but also desander, desilter and mud cleaner to separate the solids in the drilling fluids. In different period, people invented different types of shaker screens, such as conventional flat screen, corrugation screens,and with square meshes, hexagonal meshes, diamond meshes, etc. And different geological condition may require different ability and type of shaker screens.

In drilling mud solids control system(http://www.kosunsolidscontrol.com/solids-control-system/), shaker screen can be used in order to successfully blend as well as hydrate materials additional in to liquid. Along with big capability, higher raise, as well as lengthy dependable support existence, the actual shaker screen may accelerate dilution as well as hydration associated with polymers to possess home dirt.(http://www.kosunsolidscontrol.com/product-accessories/shale-shaker-screen.html)

The shaker screen is equipped on the basket of shale shaker(http://www.kosunsolidscontrol.com/solids-control-equipmen...), with three or four pieces screen panels, while the screen basket is driven by two sets of vibration motors which are mounted on the top of shale shaker with synchronization and contrary rotation. There exists one piece of eccentric block in the vibration motor. When motor works, the eccentric block also rotate. As there are two sets of vibration motors working synchronized, at some point, the vibration force that generated by the eccentric blocks is sum of these two blocks effect force. While at some point, the vibration force of motors would be zero.

Shaker screen may shear polymer bonded whilst move, as well as allow it to be diluted as well as hydrate as quickly as possible. An additional cause is actually, the actual molecular pounds associated with macromolecule polymer bonded is actually family member higher, it’s not simple to dissolve within drinking water. In this instance, polymer bonded supplies have to be pre-cut prior to combining or even moving. Shale shaker screen can offer higher shear effectiveness. Accelerate the actual dilution from the polymer bonded, and also the hydration procedure.


Operational Recommendations of Shaker Screen

1. Use enough shakers to supply enough non-blanked screen area to run 100 mesh or finer screens. Shaker set up ought to be enough to approach solids-laden fluids at maximum flow rates more than any significant hole interval. If enough shakers usually are not readily available, treat 100% in the mud circulating volume via the accessible units.

2.For double-deck shakers, run a coarser screen on leading and also a finer screen on bottom. The coarser screen really should be at the very least two meshes coarser. Watch to get a torn bottom screen. Replace or patch torn screens at once. Cover 75% to 80% from the bottom screen with mud to maximize utilization in the obtainable screen area. Flow back pans are encouraged for improving coverage and through put.

3.For a single-deck shaker with parallel screens, try and run all the similar mesh screens. If coarser screens are necessary to protect against mud loss, no greater than two meshes really should be around the shaker at one particular time, using the finer mesh screen closest towards the possum belly. The two meshes need to have approximately precisely the same size opening. For instance, use a combination of one hundred mesh (1400 and 80 mesh (178g), not one hundred mesh (140k) and 50 mesh (279g). Cover 75% to 80% in the screen location with mud to correctly use the screen surface region.

4.Use spray bars (mist only) as needed for sticky clay, and so forth. Use spray bars only with unweighted muds. Spray bars are certainly not encouraged for weighted or oil primarily based muds.

5.Usually do not bypass or operate with torn screens; they are the primary causes of plugged hydrocyclones. Use screens with mesh backup so that coarser solids is going to be screened out when the finer mesh tears.

6.For enhanced screen life with non-pretensioned screens, make certain the components from the screen tensioning program, which includes any rubber supports, nuts, bolts, springs, and so forth., are in location and in superior shape. Install screens according to the manufacturer’s advisable installation procedure.

7.Check the bearing lubrication based on manufacturer’s maintenance schedule. Lubricate and retain the unit in accordance with manufacturer’s guidelines.

8.Rig up with enough space and walkways with handrails about the shaker skid to permit quick service. The shaker skid should be level.

9.Check for appropriate path of motor rotation for shaker screen with one vibrator.

10.The flow line should really enter at the bottom of the possum belly to prevent solids settling and buildup inside the possum belly. When the flow line enters more than the best from the possum belly, the flow line ought to be extended to inside 8-10 inches of the bottom of your possum belly.

11.Rig up for equal fluid and solids distribution when more than one shaker is applied. A cement bypass is desirable.
