As we all known that a complete set of solids control system for oil and gas drillinf or for other kinds of drilling always includes desander cyclones and desilter cyclones which are not driven by motor or engine but with the high pressure of the drilling mud pumped into. So you will see normally there will be a centrifugal pump to deliver drilling fluids to the cones with a presurre in a tangent line so that the drilling fluids can rotate inside the cones, lighter liquid upward out through leading pipes, heavier solids downwards out through sand dischargeing channel. Beside desander and desilter cyclones, Hebei GN Solids Control also supplies centrifugal pumps specailly designed to deliver drilling fludis with the ablity to handle abrasive, viscous and corrosive medium, which are currently in operation for onland drilling and offshore drilling around the world. If comoared with other pumps, GN centrifugal pumps owns an excellent performance, handles large volums, bears high temperature, enjoys a long service life and easy maintenance.
The flow parts includes stuffing box, impeller, and housing assembly. These parts are poured from the highest grade of ductile iron, then finished to exacting specifications. After machining and inspection, these parts are processed through a quench and temper heat treating process to fully harden the parts throughout. During this process the parts are hardened to 40-44 ROCKWELL-C scale, this gives the "SB" parts the hardness to withstand the harshest pumping conditions. Look to the pumps for extended pump life. Besides delivering drilling fluids, GN centrifugal pump also can be used for mixing with the mud mixing hopper on the top. How many centrifugal pumps needed depends on the treating capacith of the solids control system, and the capacity of centrifugal pump should be matched to the capacity of desander and desilter.
Situated in an industrial area near Beijing, Hebei GN Solids Control Co., Ltd has grown into the top manufacturer of solids control equipment and system for oil and gas drilling and mud cleaning and recycling equipment and system for other kinds of drilling such as horizontal drilling, Coal Bed Methane drilling, geothermal drilling, tunnling and bore piling in construction field as the first API certified in China, also certified by Europe DNV CE, Russia TR&TC; ATEX and IEX EX for all electric control panels. From the solids control system extending to mud system for other kinds of drilling, Hebei GN Solids Control is now in a leading position of solids separation equipment in China. Here the mud system for bore piling in construction field will be introduced. Because this kinds of system does not include mixing device and always contains twostage treatment in one machine for a compact design to save space, generally this kind of system is also called GN economic mud system, or mud cleaning unit. As a contrast to GN economic mud system, GN high standard mud system with mixing device and sometimes 3 or 4 stage treatment is also available, normally for HDD, CBM, be introduced in next week.
GN economic mud system for bore piling normally includes two stage treatment. The first one is coarse solids separation by shale shaker; the second is relatively finer solids removal by desander cones with bottom shaker. To save space, a double deck shale shaker with the desander cone on the top is our standard equipment. The bottom deck serves as shale shaker, the top deck as the bottom shaker of desander cone, as can be seen form the picture. Now at least 8 sets of GN economic mud system is operating in Myanmar.
As the top manufacturer solids control system in China, GN Solids Control is an expert in solids separation equipment. Besides solids control equipment and system for oil and gas drilling, GN solids control also design and manufactures mud recycling system for HDD and CBM drilling. Different from the solids control system for oil and gas drilling, mud recycling systems for HDD and CBM drilling only needs 2 or 3 stages treatment equipment：shale shaker&desander or desilter; shale shaker&desander&desilter, sometimes shale shaker&mud cleaner with the combination of desander and desilter to save space, and also desander or desilter unit with double deck screen shale shakers to save space; the bottom deck of screen is used as the first stage treatment equipment shale shaker to separate coarse solids from the mud, and the liquids from the first deck screen will be delivered into the desander cones or desilter cone for 2 stage treatment; the top deck screen is used to dry the liquids from the cones.
For GN mud recycling systems for HDD and CBM drilling, pls note the below points.
1. GN provides various treating capacity mud recycling systems from 50GPM to 2000 GPM with standard unit 150GPM/ 350GPM/ 500GPM/ 1000 GPM.
2. In GN solids control, Skid Mounted mud tank, or Trailer Mounted, or Hydraulic Jack Up mud Recycliing system are optional according to customer requirements.
3. Self-contained unit with self-cleaning tank for easy maintenance.
4. Foldable walkways and handrails allow to you move without removing from tank.
Besides the standard unit of mud recycling systems, GN also provides considerate services. Before sales, GN will provide solids drawing to let the customer to confirm, after confirmed, GN will start to manufacture. After sales, GN will dispatch engineers to do commissioning, to maker sure GN system operates well.
As a top manufacture of solids control machine, GN solids control can design and manufactures various kinds of solids control system for oil and gas drilling; geothermal drilling, water well drilling, HDD, CBM, Piling and so on. One of mud recycling system was delivered to Niger for water well drilling, and our after sales team came back this week after commissioning of this mud recycling system. Niger is one of the least developed countries in the wold whose economy source mostly comes from agriculture. Since 2013, the government was committed to develop economy and attract foreign investment with a relatively stable politics condition. While because of the natural disadvantage( shortage of water for the close location to the Sahara desert), small market and large up-front capital investment restrictions, Niger is still experiencing difficulties in developing economy.
This time, GN after sales team came to Niger for commissioning for our customer who has got ready for water well drilling. The full details of this system are listed as below.
1/ The drilling rig was purchased from Drillmec, an Italy brand.
2/ 1 set of double deck shale shaker with desilter cyclones, solids over 25microns will be separated out.
3/ 1 set of mud hopper for chemical mixing and bentonite addition,
4/ 1 set of mud recycling system with one desiltering compartment and one mixing compartment.
5/ 1 set of clean tank used to store clean mud
Besides mud recycling system for water well drilling, GN solids control is also specialized in oil and gas drilling with shale shaker for the first stage treatment, desander for second stage treatment, and desilter for third stage treatment, and decanter centrifuge for the final stage treatment. Also many two stage treatment equipment of mud system for other kinds of drilling.
