Even though the passing year is really law the oil and gas industry, typically the crude oil price is into the bottom low record in the past 11 years. There is continue to need for solids control devices, this time, maybe not for oil and coal drilling, but for the HDD drilling projects, the CBM drilling projects and occasion the TBM piling operates.
The principle and functions for any mud recycling systems intended for other drillings like HDD, TBM or water very well drilling are same as solids control systems, the equipment essential:
1 . shale shaker, a single set or two, which is made the decision per the requested dealing with capacity of the whole system,

2 . desander and desilter cones, in HDD drilling, especially the large capacity HDD drillings, there is always a mud cleaner combining both desander cones and desilter cones. For smaller HDD mud systems, there is a desilter mud cleaner only. And for TBM works, because the treating typical is not so strict, they will always use desander cones together with under flow shaker.
several. Mud mixing system or even calling jet mud mixer, this is a standard equipment for all those HDD projects no matter a greater capacity one or a smaller just one. Because for HDD is effective, they need to add new chemical compounds into the cleaned drilling mud, while the pilings media is definitely water, there is no need to use the particular mixing device for adding or TBM.
Of course , every single jobsite and each jobsite’s positioned country is different in natural environment standards and regulations, therefore each set of complete system is not exactly the same, like the change in locations, in configuration, and the equipment adopted.

As solids control machinery manufacture, one wear and tear parts we manufacture is the shale shaker screen. Such screen is critical for maintain consist operation cost for various type of drilling. GN Solids America’s shale shaker screen comply API RP 13C standard from API. The America Petroleum Institute screen labeling practice, API RP 13C standard:

API RP 13C uses particles to measure the coarsest particle that passes through the screen, resulting in a measured value of D100.
Historically API RP 13E’s D50 was considered the primary cut-point of the screen. Currently, API RP 13C uses D100 to compare two different screens.
Separation curves show that the D100 value is always coarser than the D50 value.

As we mention before, shale shaker screen is the wear and tear parts of shale shakers. GN Solids America LLC produce steel frame and composite frame. The frame was made with 2 or 3-layer stainless steel wire cloth. The wire cloth can be combined with the frame with metal rubber lining, or directly bonded on the frame. The main feather of the screen is every layer of wire cloth has different meshes, accurately and reasonable making screening more micromesh.

High-strength frame structure and the moderate tension screening cloth that create a reliable whole, greatly enhance the tolerable fluid flow. The wedge tensioning devices make screen installation more convenient, and save the time of machine-stop for screen changing. The

wire cloth is divided into several independent small cloths to prevent excessive expansion of damage. Excellent constructed frame and high-strength injection frame enhance corrosion resistance, have good shock absorption and extend working life of screen.

Centrifuge for Solids Control and Waste Management

Leave a reply

In oil and gas industry for solids control equipment, the centrifuges are more and more used for separating out the fine and extra fine particles from the drilling mud system. In fact, they are taking over the former position of hydrocyclones like the desander cones and desiter cones.

Depending on the applications, the centrifuges could be divided as following items. And GN Solids Control, as the leading centrifuge manufacturer in China oil and gas industry, GN has a complete series of centrifuges, and such centrifuges cover all applications needed in the solids control and waste management systems as below:

1. solids control centrifuge. This is the centrifuge used in solids control system, as the fourth step for separate out the solids from the drilling mud. Normally, there are 2 centrifuges used in a solids control system for a large horse power system, one is for separating the valuable drilling material barite, which is expensive in price and could be re-used in future projects, the other is for separating out the particles which are too fine for the desilter cones. In most cases, GN clients use GNLW452 for barite recovery and GNLW363-VFD for extra fine particles in solids control system.

2. waste management centrifuges, for further treatment of the drilling liquid, the dewatering centrifuge. When the drilling fluid is used and reused for several times, there are extra fine particles in the drilling fluid are too fine for the centrifuge itself to get them out. So the end users need to add chemicals to merge them to be bigger, big enough for the centrifuges. In this case, GNLW363CG-VFD is recommended as the dewatering unit. And also, GN has dewatering unit available.

3. waste management centrifuge for further treatment of the solids discharged from the solids control system. When the solids are collected from the solids control system, they are not dry enough and couldn’t be discharged directly. So for the water based mud, there’s a drying shaker of High-G force and for the oil based mud, there’s a vertical cuttings dryer before the decanter centrifuge. GNLW363CG-VFD of high speed decanter centrifuge is ideal for this application. And GN also has GNZS594HGE-LD drying shaker and GNCD930CD Vertical cuttings dryer for the complete system.
