nowadays the drilling liquids is broadlyutilized in drilling projects and underneath the strict regulation on atmosphere protection, the ways to minimize the release of environment hazardous waste solids and maximum the drilling liquids recovery must be the mainstream subject in the industry.
The using of mud tank to keep the drilling liquids returning in the drill well continues to be broadly identified and accepted by all of the drilling companies. Without digging a mud pit on the floor help reduce the pollution towards the soil. Specifically for some limited job area, the mud tank will be the preferred option for drilling liquids. The using of the several types of the solids control equipment highly accelerates the separation of solids in drilling liquids.
The closed loop drilling mud solids control system, if complete configuration, consists 2 parts. Drilling mud is used in solids control and waste drilling cuttings treatment. The objective of this 2 parts is similar for minimize the release of environment hazardous waste solids and maximum the drilling liquids recovery.
For solids control, after discharged rough the shale shaker, desander, desilter, the decanter centrifuge. The ultra fine solids contaminants could be removed out of the drilling mud, after that the drilling mud can be reused.
The drilling waste cuttings treatment part is performed to recovery whenever possible the drilling liquids making the cuttings dry enough for simple transportation to help environment friendly through treatment. The cuttings out of the solids control shale shaker and desander, desilter could be moved to drying equipment first. The drying equipment could be different due to that the water based mud or oil based mud can be used. A higher G drying shaker is the best for water based drilling mud cuttings. The Verti G cuttings dryer is always utilized for drying the water based and oil based cuttings.
