Drilling Cuttings Waste Management System
Drilling waste management is a common name for drilling cuttings treatment, also known as drilling fluid non-grounding.Drilling Cuttings Waste Management System is used for taking drilling fluids from the drilling cuttings and clean the fluids for resuse. It is to maximize the recycling of drilling fluids, and minimize the drilling waste in order to save cost for operators.
For oil based drilling cuttings, normally it can reduce the oil on the cuttings to 3% to 5%.
For water based drilling cuttings, normally it can reduce the moisture content for easy transportation.
Recycling drilling fluids for reuse to save cost .
Reduce the drilling waste quantity to save money on the disposal or further treatment.
Definition of Drilling Waste Management
“Standard treatment technique of drilling waste management” means that waste drilling mud is processed immediately while drilling to meet the requirements of mud not landing. This reduces land use and environmental pollution.
Working process of drilling waste management is described as follows:
The mud from drilling rig enters shale shaker (1), mud cleaner (2) through elevated manifolds, and drill cuttings discharged after the treatment (1) and (2) are transported to the vertical cutting dryer(4) for treatment through screw conveyor. The solids treated by the dryer are removed through the waste residue (5), the recovered drilling mud (6) enters drilling fluid mud tank (7). Centrifuge supply pump or screw pump (8) extracts the fine solid particles. The recovered mud is supplied to the centrifuge (9) for processing, solid part is removed through the solid discharge port (10), and the processed drilling fluid returns to mud system (11) through the clean mud.
