HDD FLUID CLEANING SYSTEMS: Reducing Increased Costs of HDD Operation

摘要

During the operation, unprocessed slurry in the exit side pit averaged as high as 11 percent sand content. Due to Derrick's patented Pyramid screen technology and leading-edge shaker design coupled with proper pump and cone design of the M200D, the clean mud's sand content was maintained at .5 percent or less throughout the duration of the job. Fluid was only added for hole volume and no known losses occurred during the operation. The job demonstrated the ability of a compact, single-deck fluid recycling system with high performance shaker and innovative screen technology to provide value added savings by way of reducing the dilution needed and the quantity of abrasive sand size particles. Findings showed the M-200D with its' next level design and components to be as effective as larger conventional mud systems with double deck shakers and/or multiple shaker systems.
