Compartir:

Because hydroxyethyl cellulose (HEC) has good thickening and water retention characteristics, it plays an important role in oil drilling engineering. It can thicken mud, control fluid loss, lubricate drill bits, etc., and improve drilling efficiency and safety. It is widely used in daily chemicals, coatings, building materials and other fields.


Tengda is a reliable supplier of cellulose ether, with decades of experience in the industry, from procurement to production, every link of Tenda's scientific research personnel will carry out strict detail control, our philosophy is: to produce the highest quality products , providing the most reliable service.


HEC (Hydroxyethyl Cellulose) is a water-soluble polymer that is also widely used in oil drilling. It is mainly used in drilling fluids. Its applications, requirements and advantages are as follows:


Application of HEC in oil drilling:


1. Thickener: HEC can be used as a thickener for drilling fluid, increasing the viscosity and viscosity of drilling fluid, increasing its suspension volume and carrying capacity.


2. Viscosity regulator: HEC can be used as a viscosity regulator for drilling fluids to adjust the viscosity and rheological properties of drilling fluids to meet the drilling needs of different well sections.


3. Suspending agent: HEC can be used as a suspending agent in drilling fluids to keep solid particles in the drilling fluid suspended and prevent them from depositing and clogging the wellbore.


4. Stabilizer: HEC can be used as a stabilizer for drilling fluid to prevent the drilling fluid from stratifying or losing fluidity downhole.


Require:


1. Moderate viscosity: The viscosity of HEC in drilling fluid should be moderate and should not be too high or too low.


2. Good solubility: HEC should have good solubility in drilling fluid and be able to dissolve quickly and be evenly dispersed in the drilling fluid.


3. Good stability: HEC should have good stability in drilling fluid and will not lose performance due to changes in downhole temperature, pressure and chemical environment.


4. Good salt resistance: HEC should have good salt resistance in drilling fluids and be able to maintain its performance in high-salinity environments.


Advantage:


1. Improve the load-bearing capacity: HEC can increase the viscosity and viscosity of the drilling fluid and increase its suspension volume and load-bearing capacity.


2. Adjust rheological properties: HEC can adjust the viscosity and rheological properties of drilling fluid to meet the drilling needs of different well sections.


3. Prevent deposition and clogging: HEC can keep solid particles in the drilling fluid suspended and prevent them from depositing and clogging the wellbore.


4. Improve stability: HEC can improve the stability of drilling fluid and prevent the drilling fluid from stratifying or losing fluidity downhole.


5. Good compatibility: HEC is compatible with other drilling fluid additives and will not react with or interfere with other additives, maintaining the stability and performance of the drilling fluid.
