Centrifuagal pump is widely used, in all the industry and agriculture even in the life. In the oil well drilling, or just water well drilling, HDD, environment protection, they are core parts though there are a lot of equipments. They charge the transportation for the separation work.
What they really do is pump the mixture of solids and slurry or drilling fluids from one stage of separation to another stage. As shown in the picture.

In the jet mixing system, they pump the fluids to go through the venture hopper, then the chemical things or other materials can be added. and then go back to the tank.

Components of Centrifugal Pump
The components of this kind of centrifugal pump, for separation work, is a little different from the others, though the structure is still the same.

Usually the drilling rig made in China are defined as ZJ Series. There are ZJ20 ZJ30 ZJ40 ZJ50 ZJ70, and because of the different capacity of the drilling rig required.

GNZS83-2 shale shaker for ZJ20

Usually for ZJ20 drilling rig, we use GNZS83-2 shale shaker, and the shaker under the mud cleaner GNZJ83-2 is

GNZS83-2, too. For the ZJ20 or 650HP drilling rig matched 90-100M3/h mud systems.

GNZS83-2 shale shaker is linear motion shale shaker holds about 80M3/h treating capacity, that means about 352GPM. It holds 2 shaker screens. The screen area come to 1.8M2 or 9.5ft2. GNZS83-2 can be used in work over drilling rigs mud system, shallow oil well drilling, such as ZJ20 rigs, as well as 100t HDD mud system. Continue reading “Shale Shaker for ZJ Series”

Main Introduction of Geological Exploration

Geological exploration is to discover resources of value from the earth, while you get some information from the earth’s surface. And it takes risks, you never know if it will work until you get the truth.An exploration geologist is a person who do this job.In addition to finding the resources needed, the core samples may also show where the easiest places to drill will be. This helps not only find the resources, but to harvest them in an efficient and cost-effective manner.

A Few Interesting Questions

1 Why do we need natural resources?
Then when you walk out, try to think about it, then you will find the answer, nearly everything around you is relative.
2 How do we find new resources?
The answer is it is a very hard work.

Geological Exploration Company

Rosneft puts much emphasis on volume and efficiency of prospecting and exploration work in order to replace hydrocarbon production with new commercial reserves and to ensure sustainable growth of production in the medium and long term. Continue reading “Geological Exploration Before Drilling”

GN Solids Control is very professional at drilling mud system, then a client tell us a very simillar application: mud recycling for diamond drilling.  The size of cuttings is the main difference with diamond drilling and oil drilling.
In diamond drilling, the cutting size will generally be less than 10 micron. And it is needed to remove 100% of solids otherwise the drilling will run in to major dramas, in a short period of time.

Some pictures of diamond drilling rigs

Centrifugal separation is one main and effective separation way, while the mixtures can distinguish by gravity, which means with the same volume, the weight is different. In solids control system, there are two way to separate the drill cuttings from the drilling mud, screening and centrifugation.
As we all know the screening machine is the shale shaker, and they separate the drilling cuttings by volume, the bigger one left and the smaller be stored to next phase.

There are kinds of centrifugal equipments in mud system: Centrifugal pumps, hydrocycolone separator (desander and desilter), and decanter centrifuge.
The centrifugal pump is used to pump the drilling mud, and make the hydrocyclones work. While the other ones is the separation equipments.

Centrifugal Pump

SB series centrifugal pump is the ideal equipment to provide impetus for Desander 、Desilter and Jet Mud Mixer. It can also be used as Charge Pump auxiliary perfusion for mud pump and Trip Pump for drilling well head. centrifugal pump is also called centrifugal pump.We considered completely the set equipment can work in excellent condition in the process of designing parameters).Most parts can be exchanged , with convenient operation and maintenance、less seal leakage、reliability、long life and other advantages.

Vacuum degasser and poor boy degasser is both are degasser in oilfield, there are some differences some maybe confused.

How do the two degasser works and the difference

The vacuum degasser suck the drilling mud and separated mud and gas by vacuum pump.

Our vacuum degasser operates on a “thin strata” principle. The drill mud enters the tank and forces it to flow and distributed to a layer of internal baffle plates engineered to allow the liquid inside the vacuum degasser to flow as thin film and is exposed to the vacuum within the vessel. This layer of mud allows the gas to escape or break out of the mud . The vacuum pump releases the gas and discharge it to the disposal line. Mud exits the vessel under the action of the venturi and is returned to the mud system.

The poor boy worked by the physical characters.

The GN MUD/GAS SEPARATOR (poor boy degasser) consists of a cylindrical pressure vessel in a fixed vertical position. Inside is a series of specially angled baffle plates, stepped from the top to the bottom. When contaminated mud is routed into the separator, it flows downward successively over each plate. During this process, the heads of entrained gases “break out.” The released gas is then carried by the vent lines to a remote location where it can be safely flared.
