| Use | It is mainly used to prepare water-bearing oil well injection fluid. At the end of the 90 s, potassium formate has been applied to drilling and completion fluid, especially in high density drilling and completion fluid system, and achieved good results. The preparation of drilling fluid system with potassium formate has the outstanding advantages of strong inhibition, good compatibility, environmental protection and oil layer protection. The field application results show that potassium formate inhibits the hydration of clay. |
| Introduction | potassium formate is a colorless transparent liquid or white solid, highly moisture-absorbing, reductive, capable of reacting with strong oxidants, density of 1.9100g/cm3, soluble in water, saturated solution of specific gravity of 1.58g/cm3, non-toxic corrosion. Potassium formate can be synthesized by heating carbon monoxide with potassium hydroxide, and formic acid is obtained by further acidification and distillation. Figure 1 shows the molecular structure of potassium formate. |
| effect of formate on drilling fluid | PDF-THERM drilling fluid is a seawater-based high temperature and high density polysulfonate drilling fluid system, it is mainly composed of temperature resistant polymer and sulfonated material. Like other polysulfonate drilling fluid systems, the drilling fluid usually maintains the performance of drilling fluid at high temperature by adding a large amount of polymer and sulfonated material. In addition, because of the use of seawater to prepare the drilling fluid, there is a higher requirement for the use of temperature resistant polymers. PDF-THERM when the drilling fluid system is in high density, the solid phase content of the drilling fluid is increased due to the addition of a large number of weighting materials. The introduction of formate can also strengthen the inhibition of clay dispersion, potassium formate can improve the temperature resistance of the main temperature resistant polymer of PDF-THERM system, which has a positive effect on reducing the amount of temperature resistant polymer and controlling the solid phase content of high density drilling fluid. After adding potassium formate, the inhibition of drilling fluid can be improved, and the hydration and dispersion of shale in the formation can be inhibited. At the same time, because formate can improve the density of drilling fluid base fluid, the amount of barite can also be reduced under the condition of the same density, this reduces the solid phase content of the high-density drilling fluid and alleviates the viscosity increase caused by the contamination of poor-quality soil. Barite can be dissolved in potassium formate solution, but this is related to the concentration of potassium formate solution, therefore, the addition amount of potassium formate should be controlled on site, and considering comprehensively, it is recommended that the addition amount should be about 30%. The scheme of adding formate in the system PDF-THERM is feasible, and it was confirmed in the high temperature and high pressure wells in the South China Sea, the properties of drilling fluid are stable, and the rheological properties are easy to control, which meet the needs of drilling fluid operation. |
| Application | potassium formate is mainly used in oil drilling, oil field drilling fluid, completion fluid, carbon black surface modifier, snow dissolving agent, mining and so on. |
| production process | add the measured formic acid and potassium hydroxide or potassium carbonate to the reactor, the weight ratio of formic acid to potassium hydroxide or potassium carbonate is its molecular weight ratio. Start the reactor cooling water system, start the stirring device of the reactor, and control the reaction temperature in the reactor, then the potassium formate is sent to the evaporator, and the temperature is controlled at 180 to 210 ° C. In the evaporator to evaporate the water generated by the reaction in the potassium formate, and the potassium formate is in a molten state. |
| solubility in water (g/100ml) | grams dissolved per 100ml of water at different temperatures (℃): 313g/10 ℃;337g/20 ℃;361g/30 ℃;398G/40 ℃; 471G/60 ℃;580g/80 ℃;658G/90 ℃ |
| Application | is mainly used for the preparation of water-bearing oil well injection fluid, and potassium formate has been applied to drilling and completion fluid in the late 90 s abroad, especially in the application of high-density drilling and completion fluid system, good results have been achieved. The preparation of drilling fluid system with potassium formate has the outstanding advantages of strong inhibition, good compatibility, environmental protection and oil layer protection. The field application results show that potassium formate inhibits the hydration of clay. |
