GN is making 4 complete sets HDD mud recovery system for CHINA PETROLEUM PIPELING BUREAU(China CPP). The first 2 sets is ready for shipment now.

Many visitors to GN Beijing factory showed great interest in this customized system. Here is a brief introduction of the system.

It is a 4-stage mud solids control separation system, with capacity can reach up to 1000GPM. The system is including following equipment:

1) 1 set Mud desander cleaner GNZJ705-2S, with double deck shale shaker GNZS705. It is for the first and second stage separation.

2) 1 set Mud desilter cleaner GNZJ705-12N, with double deck shale shaker GNZS705. It is for the first and third stage separation.

3) 2 sets middle speed decanter centrifuge GNLW452. It is the 4^th stage separation machine. Centrifuges here are used for reduce the mud weight. As the total system reaches up to 1000GPM capacity with dual shakers. Here we matched 2 sets decanter centrifuge for a bigger capacity. It can separate solids to 5~7microns. With centrifuge, the mud can be separated more clean and suits for more deeper drilling.

4) To avoid mud settle down within the tank, GN equipped 1 ea mud agitator under each decanter centrifuge. So totally 2 mud agitators for the system.

Both of the double deck shale shaker, the bottom deck screen can be used for shale shaker. The upper deck is used as desander or desilter separator. The 2 shakers are collected through mud distribution box, and controlled by pipes and vales for mud feeding.

The double deck desander mud cleaner and desilter mud cleaner are equal to 2 sets single deck shale shaker, a separate desander and desilter machine. But it is more compact than the 3 separated machine and takes a smaller footprint.

It is a 2-tank mud system. The same with all other systems to CPP, the tank size is the same with 20ft standard container. And it is equipped with container lifting eyes. 2 sets mud cleaner on tank 1#, both of the mud cleaners are mounted on a 20ft size ski8d with frame. While the dual decanter centrifuges located on tank 2# are mounted on another 20ft skid with frame. It is easy for customer to move and mount equipment at jobsite. They only need to lift or remove the 20ft skid frame during shipment.
