The working principle of Vertical drilling cutting dryer

In offshore and onshore drilling projects, the mud lost due to the malfunction of the drilling mud solid control equipment, as well as the drilling waste separated from the solid control equipment, the untreated drilling mud and drilling waste formed due to the relocation of the drilling well pad and the historical backlog have become a major factor of environmental pollution.

The increasingly strict environmental protection laws and regulations of various countries and regions make oil and gas field operators and drilling contractors feel pressure. Therefore, the discharge of drilling waste must be reduced and the original drilling mud and drilling waste disposal process must be changed. At the same time, the shift in oil prices makes it increasingly essential to recycle water, diesel oil and other valuable mud materials through scientific and reasonable drilling waste disposal process to save drilling costs.

Working principle of the rock cuttings dryer: drilling cuttings fall into the internal separation area from the slurry feeding hopper at the top of the rock cuttings dryer. With the high-speed rotation of the inner cone rotating body, the rotating body generates a great centrifugal force (separation factor of 360). Due to the different gravity of liquid phase and solid phase, the mud attached to the drilling cuttings will pass through the screen, while the solid phase will remain inside the screen. The liquid phase will be discharged from the manifold, and the dry solid phase will be discharged from the bottom of the equipment. The vertical cuttings dryer can effectively treat water-based, oil-based and synthetic based drilling fluids, and produce very dry drilling cuttings, reducing the discharge of drilling cuttings, recovering a large amount of drilling fluids, reducing drilling costs, and protecting the environment.

The vertical cuttings dryer can effectively treat water-based, oil-based and synthetic based drilling fluids, and produce highly dry drilling cuttings, reducing the discharge of drilling cuttings, recovering a large amount of drilling fluids, reducing drilling costs, and protecting the environment.

The vulnerable parts of the drilling cuttings dryer are mainly bearings, screen baskets and belts, which have a service life of more than 6 months and are easy to buy in the market. Each replaceable component shall pass the dynamic balance test to meet the overall balance after component replacement Independent oil cooling system, equipped with scientific oil tank cooling system, can effectively meet the needs of high temperature environment.
