GN’s drilling mud recycling system is always equipped to the drilling rig and provided together to the end user. Just like the China domestic rig manufacturer of SJ from Sinopec and RG from CNPC who always get the drilling mud recycling system from GN solids control to equip with their drilling rig, the provide to their customer together. Not too long time before, GN finished on set solids control system for 750 HP drilling rig for Sinopec SJ’s Turkey project.
750 HP rig in China would also be referred as ZJ30 which could drill to depth of 3000 meters. The drilling mud recycling for this rig is configured as below:
4 units’ mud tanks systems include 1 recycling tank, 2 active mud storage tanks and 1 mixing tank. On the first tank for sand trap, there is also a compartment used for trip tank. When the drilling pipe need to be pulled out and changed, the drilling mud in the trip tank compartment would be pump back to the drill hole for protecting the well wall and keep stable downhole pressure.
This mud recycling system is a 3 stages design with shale shaker, mud cleaner (de-sander & de-silter). 2 units of GNZS703E-HB shale shaker have the total capacity of 240 cubic meters. The customer could adjust the feeding rate to each of the shaker by getting a flow divider. 1 unit of mud cleaner is with 2 pcs 10” de-sander cyclones and 12 pcs 4” de-silter cyclones.
On the mud storage tank, the mud agitators and mud guns would be equipped to prevent the solid particles sedimentation down to the tank bottom. Each tank would be equipped 3 units agitator and mud gun.
This system adopts the 55kw centrifugal pump for transferring the mud to the hydrocyclones and the mixing pump is the same model as consideration of future easy maintenance and repaire. The trip tank also is equipped with trip pump for pumping the mud back to the downhole.
All the electric parts like the motor and control panel are explosion proof standard especially for application in oil drilling ndustry. GN could provide complete line for oil drilling rig mud recycling system ranging from 350HP to 2000HP, welcome for contact on the inquiry and solution.
