Recently, a set of construction slurry treatment system produced by GN Solids Control has been put into use in construction mud treatment stations in North America, and the system has been successfully introduced to the international market, and will soon be sent to foreign customers, including the Middle East, Southeast Asia and other regions Engineering construction unit. The system has the characteristics of small footprint, low cost, and significant treatment effect, and can also be widely used in tunnel shield and pipe jacking projects and trenchless directional crossing projects.

This mud separation system is mainly composed of four solid-liquid separation modules: coarse screening, vibrating screen, desanding and desilting cyclone and decanter centrifugal dehydrator. Its working principle is as follows:

1. The mud tanker transports the mud produced by urban construction to the treatment station. First, the big rocks are filtered out through the collecting funnel, and then the small rocks are screened out through the coarse screen. The remaining mud is filtered and collected to the transfer station. In a jar

2. The slurry supply pump pumps the slurry from the transfer tank to the vibrating screen for further solid phase separation and removes the large particles of sand and gravel;

3. After the mud passes through the shale shaker for preliminary solid-liquid separation, it is pressurized to the desander cyclone by the slurry pump in the system. After high-speed cyclone separation, the grit components with a particle diameter greater than 40 microns are removed, and the fine sand is separated into the transfer tank, and then pressurized by the slurry supply pump to the desilting cyclone. The desilting cyclone will be more than 20 microns The particles are separated, and the mud below 20 microns is returned to the mud storage tank and pumped to the construction machinery for recycling after reproportioning.

4. The high-speed centrifugal dewatering centrifuge equipped with this system can separate the fine particles of 5-20 microns in the mud to ensure the performance of the mud.

Centrifuges produced by GN Solids Control are widely used in drilling mud treatment, sewage environmental protection treatment, oily sludge treatment, chemical and food and beverage industries.

Recently, the separate skid-mounted cuttings dryer and drilling mud jet mixing device produced by GN Solids Control have been assembled and debugged and will be sent to a domestic drilling company.

The project mainly includes 5 GNCD930-GP vertical cuttings dryers and 4 300m³/h drilling mud jet mixing devices. Vertical cuttings dryers are used on offshore platforms, mobile workboats, land oil fields, etc. This equipment is designed to be used in a class of equipment for oil drilling waste treatment operations, which can realize oil-bearing drilling cuttings de-oiling treatment and water-based drilling cuttings It uses high-power broadband dual motors as the power source for functions such as reduction and emission compliance. The processing capacity of the cuttings dryer is 30-50 tons/hour. The upper part of the equipment is conical and the lower part is cylindrical. This equipment is suitable for marine, desert and land oil field operating environments.

The jet mixing hopper device, as its name implies, refers to the mixing of water, clay (mostly bentonite) and other chemicals through the jet effect produced by the venturi funnel to achieve the effect of mixing drilling mud. Usually in the process of oil drilling and natural gas well drilling, drilling fluid can help cement the hole wall to prevent collapse during drilling rig drilling. Drilling fluid is also called drilling mud, usually divided into three categories: water-based Mud (abbreviated as WBM), oil-based mud (abbreviated as OBM) and synthetic-based mud (SBM).

GN Solids Control now has multiple sets of cuttings drying systems serving multiple oil fields in China, and processing water-based cuttings and oil-based cuttings separately. In addition, GN Solids Control also reached a strategic cooperation agreement with AKROS, a major Russian mud service company, and became a supplier of Gazprom (Gazprom for short), supplying solids control equipment all year round.

The mixing tank contains 2 sets of non-interference mud mixing hopper, which are powered by 2 independent submersible pumps. When one pump fails, the other submersible pump can be easily switched to avoid downtime.

The mixing tank adopts 2 sets of two-impeller mud agitators to prevent the drilling mud from sedimentation. In addition, it is also equipped with 2 mud guns for fixed-point flushing of the corners of the tank.

The top of the mud tank is made of mesh board. This 500BBL mixing tank adopts a skid-mounted structure, with a small rectangular size, and can be moved by a flatbed truck.

2. 7000BBL storage tank system

After the drilling mud is mixed and stirred, a centrifugal pump with quick couplings transports the drilling mud to the storage tank. The storage tank system has 14 vertical storage tanks of 500 barrels, with a total storage capacity of 7000 barrels.

These 14 vertical storage tanks are all designed with magnetic flap level gauges to display the liquid level. On the other side of the storage tank, a horizontal base is designed. When the storage tank needs to be placed horizontally, the horizontal base can ensure the stability of the storage tank. Another centrifugal pump can be used to suck and discharge the mud from the storage tank, or to suck the mud from the mixing tank.

Recently, four sets of customized 120m³/h purification systems produced by our company have been assembled and debugged, and will soon be sent to a domestic non-excavation directional drilling customer like HDD/CBM/TBM. Generally speaking, each drilling rig needs to be equipped with a set of corresponding mud purification system corresponding to the drill pipe diameter and tonnage of the rig. The goal of the mud recovery system is to separate the soil and gravel in the drilling fluid mud, and then ensure that the mud can be recycled, so as to save costs and protect the environment. The trenchless mud recovery system of the GN Solids Control brand has the advantages of compact structure, reasonable design, convenient transportation, small footprint, and high treatment efficiency. It is widely used in urban infrastructure construction such as trenchless directional crossing and mud-water balance roof. Mud treatment of pipes, shields, piling and other processes.

The standard trenchless mud recovery machine system consists of mud recovery equipment, mud mixing equipment and mud collection tanks. Unlike the mud recovery device in the oil and gas drilling industry, trenchless drilling first discharges the mud back to the mud pit on the ground, and then uses a vertically installed submerged mud pump to transport the mud to the mud recovery system. Most drilling rigs will use a three-stage Purification system, shale shaker, sand removal, mud removal, and gradual removal of rock debris and solid waste. If there is a higher separation requirement, we will add a centrifuge to the system as a fourth-stage processing equipment that can control the solid particle diameter of the slurry to 5-10 microns.

The size of the mud tank usually depends on the size of the drilling rig and the volume of the adapted mud. The mud tank is equipped with a stirrer and a mud gun to stir the mud to suspend the solids in the mud. In order to configure a suitable slurry, a jet mixing system is needed to add chemicals to maintain the properties of the slurry. GN Solids Control high-standard mud recovery system has different sizes and design schemes, and is widely used in oil and gas drilling, trenchless drilling, piling, TBM and other projects.If you are interested about our product, welcome contact us
