Drilling Auxiliaries:Strong Polymer Coating Agents for Drilling Fluids

Characteristics and Uses:
Polymer strong encapsulant B165D has a special molecular structure, and the molecular structure design can be adjusted according to the requirements of drilling projects and formation conditions to achieve the required mud properties. The agent can effectively inhibit the hydration and expansion of mud shale, control the formation slurry, and improve the flow pattern, reduce the molecular resistance, which is conducive to the optimization of drilling. 
It can be grouped with various polymers and can be effective in both fresh water and saturated salt water. It is suitable for use under high solid phase and high density conditions, and is conducive to the performance control of high density mud.

A strong curing agent for drilling fluids is a commonly used chemical additive that is used during the drilling process to prevent drilling fluids from entering the borehole through the pores of the formation rock, thus maintaining the stability of the well wall.
The following are some of the properties and characteristics of strong curing agents for drilling fluids:
1. High adhesion: Strong curing agent for drilling fluids can quickly adhere to the well wall, forming a protective film to prevent drilling fluids from penetrating into the well wall.
2. High temperature resistance: it can remain stable in high temperature environment without losing its barrier property.
3. Low permeability: it has good blocking ability, which can effectively close the pore space of the formation and reduce the loss of drilling fluid.
The main uses of strong encapsulants for drilling fluids include:
1. Protecting the stability of well wall: by forming an attachment film, it prevents the penetration of drilling fluid into the well wall and protects the stability of well wall.
2. Controlling well wall slippage: strong curing agents can reduce the pressure difference between the formation and the drilling fluid, reducing the risk of well wall slippage.
3. Reducing well leakage: by sealing the pore space of the formation, it can reduce the loss of drilling fluid and the occurrence of well leakage.
The preparation method of the strong encapsulant for drilling fluid can be carried out according to the specific formula, which generally includes such steps as dissolving the membrane polymer and adding additives.
The following safety information needs to be observed when using strong curing agents for drilling fluids:
1. Operators should wear appropriate personal protective equipment (PPE), such as safety glasses and gloves, to prevent the agent from coming into contact with the skin and eyes.
2. Observe the relevant safety operating procedures and do not bring the agent solution into direct contact with ignition sources or hot objects.
3. Pay attention to a well-ventilated environment during use to avoid volatilization and inhalation of the agent liquid.
4. Follow the storage and handling regulations of the agent liquid to avoid leakage of the agent liquid.

Company Information

Our company's main export products include

(1) Polymerized Ferrous Sulfate

Ferrous sulfate polymerization is a kind of inorganic polymer coagulant with superior performance, the morphology and properties are light yellow amorphous powdery solid, very soluble in water, 10% (quality) of the aqueous solution is reddish brown transparent solution, hygroscopicity. Ferrous sulfate polymerization is widely used in the purification and treatment of drinking water, industrial water, all kinds of industrial wastewater, municipal wastewater, sludge dewatering and so on.

(2)Polyaluminum Chloride

The color of polymeric aluminum chloride is yellow or light yellow, dark brown, dark gray resin-like solid. The product has strong bridging adsorption properties, in the process of hydrolysis, accompanied by the occurrence of cohesion, adsorption and precipitation and other physicochemical processes. The fundamental difference between polymerized aluminum chloride and traditional inorganic coagulant is that traditional inorganic coagulant is low molecular crystalline salt, while the structure of polymerized aluminum chloride consists of multiple carboxyl complexes with variable morphology, with fast flocculation and precipitation speed, wide range of pH value, no corrosive to pipeline equipment, obvious water purification effect, and can effectively support the removal of color SS, COD, BOD and arsenic, mercury and other heavy metal ions in the water, which are widely used in drinking water, industrial water and sewage. The product is widely used in the field of drinking water, industrial water and sewage treatment.
