Solution Overview
Problem
Existing shearing systems for drilling mud fail to effectively shear smallest particles and disrupt fluid flow, leading to inadequate homogenization and suboptimal rheological properties in drilling operations, particularly when handling water-based, oil-based, and synthetic-based muds.
Innovation Solution
A shearing system comprising a hollow tubular body with high-pressure pumps, jet nozzles, and a baffle plate system that pumps drilling mud through a series of jet nozzles at predetermined angles and baffle plates to disrupt water droplets and form an emulsified fluid, achieving the desired rheological properties in a single pass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional nozzle shearing systems are used, then the system structure is simple, but the system fails to shear the smallest particles and inadequately disrupt fluid flow
Solution Approach 1:
The shearing system is divided into multiple functional sections: a first shearing section with nozzles for initial shearing, and a second shearing section with additional nozzles and baffle plates for further shearing and flow disruption. This segmentation allows progressive shearing of particles of different sizes, achieving complete shearing of even the smallest particles while maintaining manageable system complexity through modular design.
Solution Approach 2:
Baffle plates are introduced as intermediary elements between the shearing nozzles and the fluid flow path. These baffle plates actively disrupt the fluid flow, enhancing the shearing effect on particles and preventing vortex formation. The baffle plates serve as mediators that amplify the shearing action without requiring direct modification of the nozzle structure, thus improving particle shearing capability while adding only moderate structural complexity.
2Productivity
If high-pressure pumping is applied, then fluid flow disruption is enhanced, but energy consumption increases
Solution Approach 1:
The emulsification process is segmented into multiple stages with progressively increasing shear intensity. The first shearing section performs initial emulsification at moderate pressure, while the second shearing section with baffle plates provides enhanced shearing for complete homogenization. This segmentation allows the system to achieve high emulsification efficiency without requiring excessively high pressure throughout the entire system, thereby reducing overall energy consumption compared to a single high-pressure stage.
Solution Approach 2:
The fluid flow experiences periodic disruption as it passes through alternating zones of high-velocity jet injection and baffle plate obstruction. This periodic action creates repeated shear cycles that enhance emulsification efficiency without requiring continuously maximum pressure, allowing the pump to operate at moderate average pressure while achieving thorough emulsification through multiple shear-impose cycles.
3Stability of the object's composition
If multiple treatment cycles are used, then homogenous drilling mud is achieved, but processing time increases
Solution Approach 1:
Multiple shearing functions that would traditionally require separate treatment cycles are merged into a single integrated flow path. The fluid passes sequentially through the first shearing section, then the second shearing section with baffle plates, achieving complete homogenization in one continuous pass. This merging of multiple shearing stages into a single integrated system eliminates the need for multiple treatment cycles while maintaining thorough mud homogeneity.
Solution Approach 2:
The shearing action is made continuous as the fluid flows uninterrupted through both shearing sections in series. Unlike batch processes that require stopping and restarting for each treatment cycle, this system maintains continuous shear action throughout the entire fluid stream, achieving complete emulsification and homogeneity in a single continuous pass, thereby dramatically reducing processing time while ensuring stable mud composition.
