Objective—Evaluation of the centrifugal pump vs roller pump concerning effects upon platelet function, hemolysis and clinical outcome in elective coronary artery bypass surgery. Design—Thirty-four patients were randomized to centrifugal or roller pump. Platelet activation was studied by flow cytometry before, during and up to 3 days after .
In the realm of Horizontal Directional Drilling (HDD), the proper management of drilling fluids is crucial for the success of the operation. The HDD Mud System plays a vital role in maintaining the integrity of the drilling process by providing the necessary lubrication, cooling, and support for the drilling equipment. Understanding the dimensions of the HDD Mud System is essential for ensuring the efficiency and effectiveness of the drilling operation.
Over the last decade, mud reclaimers (recyclers, mud recycling systems) have become a staple for mid-sized to large-diameter horizontal directional drilling (HDD) installation work.
HDD Fluid Basics to Cover HDD Drilling Requirements
HDD drilling fluids, also known as drilling mud, serve several important functions in the drilling process. These fluids are designed to meet specific requirements such as lubricating the drill bit, carrying cuttings to the surface, stabilizing the borehole walls, and controlling pressure. The composition of HDD drilling fluids may vary depending on the geological conditions of the drilling site and the specific requirements of the project.
Features of an HDD Drilling Fluid
An ideal HDD drilling fluid should possess certain key features to ensure optimal performance. These features include viscosity control, solids suspension, filtration control, lubrication properties, and compatibility with downhole tools. The ability of the drilling fluid to maintain these features throughout the drilling process is essential for achieving successful outcomes.
Functions of an HDD Drilling Fluid
The functions of an HDD drilling fluid can be categorized into primary functions and secondary functions. The primary functions include cooling and lubricating the drill bit, carrying cuttings to the surface, stabilizing the borehole walls, and controlling pressure. Secondary functions may include reducing friction, preventing formation damage, and enhancing hole cleaning. A well-formulated drilling fluid should effectively perform these functions to ensure the efficiency of the drilling operation.
Initial Mud Volume Calculations
Calculating the initial mud volume required for an HDD drilling operation is a critical step in the planning process. Factors such as bore length, diameter, annular volume, and anticipated drilling fluid properties must be taken into consideration to determine the appropriate volume of mud needed. Accurate calculations ensure that there is an adequate supply of drilling fluid to support the entire drilling process.
Reclaiming Mud on Large HDD Projects
In large HDD projects, the volume of drilling mud used can be substantial. Reclaiming and recycling mud can help reduce costs and minimize environmental impact. Large HDD projects often utilize advanced mud reclamation systems that separate solids from the drilling fluid, allowing for the reuse of the cleaned mud. Proper management of mud reclaiming processes is essential for maintaining the efficiency of the drilling operation.
Reclaiming Mud on Mid-Size HDD Projects
Mid-size HDD projects may also benefit from reclaiming mud to optimize resources and reduce waste. While the volume of mud used in mid-size projects may be smaller compared to large projects, efficient mud reclaiming practices can still contribute to cost savings and environmental sustainability. Implementing appropriate mud reclamation systems tailored to the scale of the project is essential for maximizing the benefits of reclaiming mud.
Mid-Size Mud Reclaimers
This mud mixing system mainly consists of an 18m³ mud tank, a horizontal centrifugal pump and a jet mixing hopper. The processing capacity can reach 120m³/h. The …
This ensures that the pump is fully immersed and eliminates air or gas pockets. 2. Start-up: When the pump is activated, the motor or engine drives the shaft, causing the impeller to rotate. As the impeller spins, fluid is drawn .
