 With the increasing improvement of horizontal directional crossing technology and the increasingly strict requirements of the state on environmental protection policies, the horizontal directional crossing solid control system also has higher requirements. Horizontal directional crossing of solid control equipment is mainly reflected in the obstacles such as oil and gas pipelines crossing rivers, lakes, transportation trunks, and railway junctions. There are also a variety of separation techniques for the principle and technical method of horizontally directional crossing solid control to control the solid particles in the mud.

Environmental protection is a sensitive topic for us for a long time. Because the horizontal directional drilling mud contains many harmful substances and is of high value, the recovery of mud in the horizontal directional crossing system is the primary requirement of the owner for the construction. Construction units of horizontal directional crossing have purchased mud solid phase control equipment one after another to separate the waste solid phase and reuse it, turning waste into treasure, and have achieved considerable economic benefits. At the same time, it has also promoted the development of domestic horizontal directional through mud solid control system.

Horizontal directional crossing has not been developed in China or even the world for a long time. It does not have its own perfect system in drilling and mud. At present, it is largely absorbed and applied after the improvement of the oilfield process system. At the domestic level, the solid-phase separation method of directional through mud is somewhat similar to that of oil fields. There are mainly three methods of dilution, sedimentation and mechanical removal. GN Solids Control analyzes the difference between horizontal directional crossing mud and petroleum drilling mud, conducts detailed analysis and conducts a lot of field research and experiments. The successful R & D is in addition to the horizontal directional crossing solid control system specially designed for horizontal directional through mud. The main equipment includes shale shaker, centrifuge, and supporting pump system

At present, the horizontal directional through mud solid control and recovery system used in China is divided into domestic and imported, and the imports are mainly small, and they are matched with the rig when imported. The domestic ones are mainly large-scale and are prepared according to user needs.

According to different construction environments, the types and sizes of particles that need to be removed or suppressed, and the quality requirements of muds that need to be maintained are different. GN Solids Control can configure a reasonable and reliable solid control system for customers according to the actual working environment needs and combined with the company’s previous successful cases.

The GN Solids Control mud purification system is widely used in solid-liquid separation conditions for various mud-water wastes. The waste mixture is separated to form useful materials. GN Solids Control recently received a customer from North America whose main business is the use of vacuum trucks to collect various waste mud and solid waste at drilling or construction sites. This customer asked GN Solids Control to design and manufacture a mud-water separation system that meets his site conditions.

The picture above shows the core equipment in the mud cleaning system designed and manufactured after we inspected and combined with the actual production environment of the customer. This system fully considers the site area, the feeding method and the convenience of the processing procedure.

In this mud-water separation system, fine particle solids are separated by a shale shaker device with a fine screen. For solids smaller than 100 microns, use a hydrocyclone to separate them. At the beginning of the design, this system was fully integrated with human factors engineering. The drilling fluid shaker and cyclone part were covered by enclosures. Not only protect working parts and prevent mud from spraying to pollute equipment, but also fully consider and ensure the safety and convenience of operators.

For ultra-fine particulate solids in mud, the system will use a decanter centrifuge system and a chemical dosing system for separation.

The purpose of the mud cleaning system is to separate solid waste from the mud as much as possible. Aiming at the mud produced by the hydraulic excavation project, the mud cleaning system can recycle the beneficial liquid-phase mud, and the separated gravel and sand can be used to make building materials.

We also have a large number of related cases and products for customers to choose from. If you have related requirements, please feel free to contact GN Solids Control.

This week, GN Solids Control completed a batch of drilling fluid shaker orders for Russian customers. All shakers are assembled and tested and will be shipped later.

The drilling fluid shaker device has always been used as the first stage separation equipment in solid systems. GN Solids Control vibrating screen has been used in domestic and international drilling sites, and has been well received. The following characteristics of GN Solids Control drilling fluid shaker make it widely praised.

1. GN Solids Control drilling fluid shaker has a simple structure. Every part of the shaker can be easily identified and assembled, making it easy to operate the shaker.

2. In order to ensure the processing capacity, the deck of the GN Solids Control vibrating screen is heat treated and can withstand the high vibration force. Depending on the operator, the shaker table angle can be adjusted during machine operation. By adjusting the panel to a negative angle, you can increase the flow. By adjusting the cover plate to a positive angle, the liquid accumulated on the screen can be increased, and the discharged solids can be dried. The shaker deck is also equipped with locking devices for security purposes.

In the GN Solids Control assembly shop, a set of drill cuttings solidification equipment is ready for shipment to the GN Solids Control customer site. Cuttings solidification equipment is the most ideal equipment for water-based cuttings processing. GN Solids Control This device has been upgraded several times since its first release in 2014. The better design and easier installation make this device more and more popular with customers.

How GN Solids Control drill solidification equipment works

GN Solids Control curing equipment is mainly used as the final stage processing equipment in drilling and cutting management system. It collects the waste debris discharged from the mud recovery equipment and mixes it with coagulant and desiccant to make the waste debris into water-insoluble compounds so that toxic chemicals and heavy metal ions will not penetrate into the soil and underground. Water mixed.

Optimized Design of GN Solids Control Drill Cuttings Solidification Equipment

1. GN Solids Control changed the design of one skid and divided the whole device into two skids. This gives users the flexibility to position the system on site and each skid will be easier to transport. The two slide rails are connected using steel bars to maintain the distance and stability of the entire system.

2. The curing agent and desiccant are stored in the separation tank, which is easy to operate and can be accurately added to the mixing cabinet. The cabinet has a liquid inlet that can be connected to a hose for other types of chemical injection.

3. In order to ensure uniform stirring, water spray pipes and nozzles are also installed on the mixing cabinet to prevent the materials from being too dry to stir. The spray hose can also be used for flushing after use.

4. The mixing cabinet has observation and maintenance openings from which the operator can perform maintenance. A limit switch is installed on the cover of the observation port to prevent the machine from running without closing the cover.

Recently, GN Solids Control has undertaken the development and production of a Oil sludge treatment system for a domestic oilfield unit. The project mainly deals with oily solid wastes in sludge storage tanks. After the oily solid wastes have been prepared, sieved, cleaned, demulsified, and finely screened, they have now achieved reductions and preliminary separation. The oil-containing sludge three-phase separation system uses a combined process of a two-phase horizontal spiral centrifuge and a three-phase disc centrifuge to perform final solid-liquid-liquid three-phase separation of subsequent materials to realize the harmless separation and disposal of resources.

System process description:

After the sludge is metered at the inlet, it is pumped to the decanter centrifuge by a booster pump. At the same time, the chemical dosing system injects flocculant into the decanter centrifuge to promote the solid-liquid two-phase separation of the decanter centrifuge. The separated solid phase is transported externally via a screw conveyor. At this time, the liquid content of the solid is <85%, and the solid content of the separated liquid phase is <3%. The solid phase flows to the waste liquid buffer tank through a closed pipe, and the waste liquid buffer tank. Equipped with a liquid level transmitter, the liquid level signal can be displayed locally and remotely. The solid phase settled at the bottom of the waste buffer tank can be returned to the decanter centrifuge for reprocessing through the inlet booster pump.

The process is as follows:

The liquid phase outlet of the waste liquid buffer tank is pumped to the disc centrifuge inlet through a 3um solid particle filter (protecting the downstream disc centrifuge), and the solid, oil and water are separated by centrifugation, and the separated solid phase is stored. Into a solid waste storage tank that can be transported; the water content of the separated oil phase is less than 10%, and temporarily stored in the sewage oil buffer tank; the solid content of the separated water phase is less than 1%, and temporarily stored in the sewage buffer tank The oil and water phases are metered out by centrifugal pumps. Sewage buffer tanks and slop oil buffer tanks are equipped with liquid level transmitters, which can display liquid level signals locally and remotely; the two centrifuges need to achieve structural sealing, and have start-stop, variable frequency, speed, bearing temperature signal feedback and Status information feedback functions such as alarm, centrifuge material overload current signal feedback and alarm, with nitrogen protection and independent flushing water circuit.
