В чем преимущества системы бурового раствора на основе формиата калия?

(1) С Калиум формат drilling fluid, you can enjoy excellent solubility, high density, low solids content, low viscosity, and good compatibility. By using a small amount of water-based weighting agent and adding an appropriate amount of gel during weighting, the high-density potassium formate(HCOOK) system can maintain low viscosity and low fluid loss.

(2) Когда речь идет о таких породах, как формация реки Аньцзихай и формация реки Таксигай, которые имеют сильную дисперсность на южной окраине бассейна Джунгар, буровой раствор на основе формиата калия, приготовленный в лаборатории, проявляет хорошие ингибирующие свойства. Его потребительская ценность также заключается в хороших характеристиках текучести, что делает его подходящим для геологических условий южной окраины.

(3) The HCOOK system has a strong ability to resist calcium and solid-phase contamination. This makes it advantageous for drilling through complex sections.

(4) Even after being subjected to a thermal rolling test at 150°C for 16 hours, the high-density HCOOK drilling fluid shows minimal performance fluctuations. It can withstand high temperature and ensure the stability in the drilling process.

(5) Даже при плотности 2,62 г/см3 буровой раствор на основе формиата калия сохраняет хорошую смазывающую способность, что очень важно для обеспечения безопасности буровых работ.

Калийный буровой раствор высокой плотности обладает хорошими смазывающими свойствами, что очень важно для предотвращения сложных аварий (таких как дифференциальное налипание и обеспечение безопасного проведения буровых работ).

 

1. What are the key benefits of using potassium formate drilling fluid?
   • Key benefits include excellent solubility, high density, low solids content, low viscosity, good compatibility, and strong resistance to calcium and contamination.
2. How does the HCOOK system maintain low viscosity during high-density operations?
