Hydroxyethyl Cellulose Manufacturer

Introduction to Hydroxyethyl Cellulose：

Hydroxyethyl Cellulose (HEC) is a non-ionic water-soluble polymer and one of the cellulose derivatives. It is formed by combining cellulose with oxyethylene groups and has abundant hydroxyl functional groups. The chemical structure of HEC contains hydroxyl (-OH) functional groups, which gives it good water solubility and gelling properties. Due to its unique chemical structure and properties, HEC is widely used in various fields, including construction, coatings, medicine, food, personal care products, etc.

Why can the fluid loss performance of drilling fluid be greatly improved after using HEC? How can this help reduce mud loss and thereby reduce drilling costs?

After using HEC, the fluid loss performance of drilling fluid can be greatly improved, mainly for the following reasons:

1. Form a protective film: HEC forms a strong protective film in the drilling fluid, covering the surface of the well wall, filling pores and cracks, forming a physical barrier to prevent drilling fluid from seeping and leaking into the formation. This protective film can effectively seal the gap between the well wall and the formation and reduce the loss rate of drilling fluid.

2. Increase the viscosity of drilling fluid: As a thickener, HEC can increase the viscosity and viscosity of drilling fluid, enhance the adhesion and adhesion of drilling fluid, slow down the penetration rate of drilling fluid in the well wall and formation, and reduce the penetration rate of drilling fluid in the well wall and formation. filter loss rate.

3. Improve the rheological properties of drilling fluid: HEC can adjust the rheological properties of drilling fluid, improve its fluidity and uniformity, reduce the loss and consumption of drilling fluid in the wellbore, thereby reducing the filter loss rate of drilling fluid.

4. Reduce the mud loss of drilling fluid: By using HEC, the fluid loss performance of drilling fluid is improved, the fluid loss speed is slowed down, and the fluid loss amount is reduced, thereby reducing the loss of solid particles in the drilling fluid. As a result, the cost of drilling fluids is significantly reduced, while downtime and workover costs during drilling operations are also reduced.

Can drilling fluids using HEC significantly reduce the release of harmful substances during drilling, thereby reducing the cost of environmental treatment and remediation?

Of course, the use of HEC drilling fluids can significantly reduce the release of harmful substances during drilling, thereby reducing the cost of environmental treatment and remediation.
Reduce the penetration of harmful substances: HEC can form a strong sealing film to cover the well wall surface, fill the cracks and pores between the wellbore and the formation, prevent harmful substances in the drilling fluid from penetrating and leaking into the formation, and reduce the impact on groundwater resources. pollute.
Reduce the risk of groundwater pollution: By using HEC, you can effectively reduce the risk of harmful substances in drilling fluids migrating and spreading to the groundwater layer, avoid contamination of groundwater resources, and reduce the cost of environmental treatment and restoration.
Reduce the risk of environmental accidents: The use of HEC can reduce the filter loss rate of drilling fluid, reduce the risk of well wall collapse and wellbore collapse during drilling operations, improve the safety and stability of drilling operations, and reduce the occurrence and management costs of environmental accidents.
Comply with environmental regulations and requirements: The use of HEC can effectively protect the formation and water sources, reduce environmental pollution and damage, comply with environmental regulations and policy requirements, and avoid legal proceedings and economic losses caused by environmental problems.
In general, the use of HEC drilling fluids can significantly reduce the release of harmful substances during the drilling process, protect the formation and water sources from pollution, thereby reducing the cost of environmental treatment and restoration, and providing an important contribution to the environmental protection and sustainable development of oil drilling operations.
