It is obvious, from the preceding discussion, that drilling waste contains a large amount of base fluid, whether that fluid is diesel oil, mineral oil, oolefin, ester, or water. A more detailed discussion about the nature or characteristics of the waste should consider the place of disposal. In a broad sense, this can be accomplished by considering that all waste must be disposed in the water, on land, or in the air. For example, the characteristics of drilling waste when discharged offshore (disposal in
water) will be viewed from the potential effects between the waste and water. These are effects to the seabed, to the water column itself, and to the air/water interface at the surface. In this scenario, diesel oil is an obvious contaminant. Diesel oil creates a sheen on the water surface, disperses in the water column, and creates a toxic effect in cuttings piles on the seabed. For this reason, diesel oil-based drilling fluids and the cuttings generated while using them are not discharged into the sea.
QUANTIFYING DRILLING WASTE
Drilling waste consists of waste drilling fluid, drilled cuttings with associated drilling fluid, and, to a lesser extent, miscellaneous fluids such as excess cement, spacers, and a variety of other fluids. The amount of drilling waste depends on a number of factors. These include hole size, solidscontrol efficiency, the ability of the drilling fluid to tolerate solids, the ability of the drilling fluid to inhibit degradation or dispersion of drilled cuttings, and the amount of drilling fluid retained on the drilled cuttings.
Drilling fluid waste High G drying shaker
High G drying shaker is mostly used to process drilling fluid or drilling cuttings. It can work more effectively with better separation result
Drying shale shaker brief introduction
Drying shale shaker is similar as common shale shaker. It can be used as first phase solids control equipment also the first stage of drilling waste management
It is usually designed in linear motion and high vibration mode, are used in processing cuttings, playing an important role in the waste drilling mud treatment. It brings customer both the economical and the environmental benefits
High G shaker vibrator motor
Obviously, Hi-G shale shaker will be utilized vibrator motor with high vibration strength to achieve high separation efficiency.
The motor can be Martin vibrator motor, Ita-Vibras, or other famous brand motor. The electronic components in starter will be top brand ones such as ABB, SIEMENS, SCHNEIDER to make the shakers more reliable and stable
Actually, if we need different vibration force we can adjust the eccentric blocks at motor ends. It can help us increase or decrease the vibration strength
Considering different clients request different electrical system please do confirm input system before order. Such as 380V/50Hz, or 380V/60Hz. We will do customization on motors and starters.
Drying shaker capacity
The drying shaker capacity is related with shaker screen area, vibration strength, and the drilling mud property. Usually, Aipu single drying shale shaker capacity ranged 500~660GPM. According to clients’ capacity demand we can configure it as dual tandem or triple tandem shaker
Aipu High G shaker screen
Presently, Aipu drying shaker model is Hunter-M series. The shaker screen sized 585x1165mm. There can be 3 panel or 4 panel for option. The popular shaker screen is composite frame one, rare client will request steel frame ones
Aipu high G shaker screen is interchangeable with Mongoose type shaker screen. We utilized high quality S.S304~316L wire cloth for reliable quality and performance
Please feel free to contact Aipu for more information on high G shaker or screen. We’ll give you optimal complete solution and suggestion ASAP.
Determination of volume percentage of low-gravity solids in water-based drilling fluid
The %vol low-gravity solids can also be calculated from the average specific gravity (ASG) of the solids in the sample:
