GN Oil Drilling Solids Control Equipment

See the photo right, it is a portable drilling mud cleaning system, it can be moved by a truck head, and when it is stopped, it can be put on the flat ground. From left to right, it is GNZS703 linear motion shale shaker 2 units, GNZJ703 mud cleaner, GN mixing hopper and mixing pump. This system treating capacity can be up to 500gallons/min, it can be used for horizontal direction drilling, water well drilling or drilling mud treatment in the plant.

We also provide another type portable mud cleaning system called trailer mounted mud system, which is put on the trailer.

GN independently design portable drilling mud system for HDD and water well drilling mud system, which is containerized for sea freight. Especially if your rig is truck mounted, you’d better use a trailer mounted/portable mud system, you only need a truck front to trail it from one site to another.

A 200gpm portable drilling mud system including a mini shale shaker, a mini mud cleaner, mixing hopper and mixing pump, and a 5.5m length mud tank. When you finish the project, you just need to pull off the walkway and hand rail to the side, and pull off the lights, then you can use the truck front to take it away. 

GN designed a set of drilling waste management system for cold area, like Russia. We put decanter centrifuge, vertical cutting dryer, screw pump, VFD control panel and electric control panel, intermediate mud tank inside a standard container, and add heat material inside the container to keep it warm.

The solids discharge port of decanter centrifuge and vertical cutting dryer is out of the container, they put the system on top of another tank to collect the waste cuttings. For convenient maintenance, we open 2 doors on the length side of the container, and the 2 sides of the container can be opened to remove the equipments. 

The function of mud gun in a solids control system is agitating and transferring. Usually it works together with mud agitator, the main body of mud gun is in the bottom of the tank, same with mud agitator shaft. Mud gun pipeline can be used to transfer mud from one tank to another. Its power come from mud pump pressure and jet mud mixer pressure.

Check the photo below for the mud gun, mud agitator and various pipelines in the tank bottom. The mud gun is operated by butterfly valve or gate valve installed on top of the mud tank.

We shipped 4 units of VFD decanter centrifuges to South America by sea. They are GN new designed GNLW363VFD centrifuge, with the features below:

1 Variable Frequency Drive, when you need to use fixed speed, you can turn to fixed speed button. Pressurized design to help cooling the VFD control panel during working and compact design.

2 ABB brand electrical components, comply with class I division I standard.

3 stainless steel 304 material bowl and screw

4 Screw protected by tungsten carbide tiles, and have spare tiles

The new design improved the quality a lot compared with the old design.

There are a lot of mud tanks in drilling rig solids control system, during operation, some slurry with oil will deposit in the tank bottom. How to clean the mud tank become a problem, tank cleaning takes time and cost a lot.

To clean mud tank, firstly you should improve the agitating performance of the mud agitator to less the sediment;secondly, you can use a pitgun to carry out this process remotely, operators and rig owners no longer need to have personnel enter mud pits or tanks to manually break up compacted solids that build up on the floor, beneath pipework, and in tank corners during the drilling process.

GNLW453 centrifuge is GN standard 300gpm centrifuge with 17 inch bowl, bowl length 62 inch. Except for 200gpm centrifuge, we also have standard 14inch bowl centrifuge, 350gpm centrifuge , 400gpm centrifuge( 21inch bowl).

GN 300gpm centrifuge is designed for un-weighted drilling fluids processing, , max bowl speed can reach 3500r/min and 3000G maximum. By changing pulleys, you can get 2 different speed in different conditions.

Injection is a method of drilling waste disposal which is aim at “ZERO” discharge nominally. Slurry injection is one of the methods, it is grinding or processing solids into small particles, mixing them with water or some other liquid to make a slurry, and injecting the slurry into an underground formation at pressures high enough to fracture the rock. Including slurry fracture injection, fracture slurry injection, drilled cuttings injection, cuttings reinjection, andgrind and inject.

Drilling waste is composed of drilling fluids, cuttings, oil, chemicals that results from oil & gas drilling. Oil & Gas drilling bring up mud and other material with high hydrocarbon levels requiring special disposal practices.

Drilling waste can not disappear, only if there is drilling, these drilling waste will occur, what we can do is to less the waste by using better solids control equipments and proper management on the waste. The Environment protection dept. should regulate more for the drilling waste disposal.

The gearbox on the mud agitator has a pre-selected gear ratio to maximize the suspension of solids in solution. This gear ratio provides a great increase in torque that is transmitted to the impeller. Any object that might fall into or be placed in the mud tank runs the risk of being caught by and wrapped up by the agitator.

Before operating the mud agitator, you must confirm the direction of the gear box, otherwise it will damage the gearbox.
