Solids removal is the fundamental purpose of the shale shaker, and improving this function delivers benefits throughout the drilling operation. More effective solids removal results in cleaner drilling fluid, lower maintenance costs, reduced waste volumes, and fewer drilling problems. Aipu shale shakers are engineered to maximize solids removal through optimized design features and operator-adjustable parameters that can be tuned for specific drilling conditions.
Select the Correct Screen for the Cut Point Required
The screen mesh directly determines the minimum particle size that will be removed from the drilling fluid. Selecting a screen that is too coarse for current requirements allows excessive fine solids to remain in the system, while selecting one that is too fine may restrict throughput. Aipu recommends establishing a clear solids removal target for each hole section based on the drilling fluid specification and formation characteristics, then selecting the finest screen that can handle the required flow rate. This approach ensures that solids removal is as complete as practical given the processing capacity available. API-certified Aipu screens manufactured with precise, consistent mesh openings provide predictable, repeatable cut points that operators can rely on for solids removal planning.
Optimize Deck Angle for Maximum Solids Conveyance
The deck angle affects solids removal by controlling how quickly cuttings are conveyed across the screen surface and discharged. If the angle is too low, cuttings move too slowly and can accumulate on the deck, reducing effective screen area and potentially causing solids to be carried over into the clean fluid. If the angle is too high, cuttings move too quickly and may not be adequately dewatered before discharge. Aipu adjustable deck angles from -1 degree to +5 degrees allow operators to find the optimal conveyance rate for current solids loading. Heavier cuttings loads in the upper hole sections typically benefit from slightly higher angles, while lighter loads in deeper sections allow lower angles that maximize dewatering.
Ensure Adequate Processing Capacity
The most common cause of inadequate solids removal is operating a shale shaker beyond its effective processing capacity. When flow rate exceeds what the screen area can handle, fluid is carried off with the cuttings and solids removal effectiveness declines sharply. Aipu addresses this through a range of capacity options, from the Hunter-Mini at 50 cubic meters per hour to the Hunter-MG4T tandem at 420 cubic meters per hour. Selecting a shaker with adequate capacity for your maximum flow rate, and preferably with a 20 to 30 percent margin, ensures that solids removal performance is maintained even during peak flow conditions.
Prevent Screen Blinding and Damage
Screen condition directly determines solids removal effectiveness. Blinded screens reduce the available area for fluid passage, causing the shaker to effectively operate with less screen area than designed. Damaged screens with tears or holes allow solids to pass through that should have been removed, defeating the purpose of the equipment. Aipu addresses these issues through vibration characteristics that minimize blinding tendencies, screen tensioning systems that reduce fatigue damage, and quick-change screen retention that makes it practical to replace screens promptly when condition deteriorates. Regular inspection of screen condition and prompt replacement of damaged panels maintains consistent solids removal performance.
Monitor and Adjust for Changing Conditions
Solids removal requirements change as the well progresses through different formations and hole sizes, yet many operators configure their shakers once and leave the settings unchanged. Aipu encourages active, condition-specific optimization. When starting a new formation or hole section, evaluate the cuttings characteristics and drilling fluid quality, then adjust screen mesh, deck angle, and if available, vibration mode to optimize solids removal for the new conditions. This active management approach ensures that solids removal performance remains optimal throughout the well rather than being optimal at one point and suboptimal at others.
