As industrialization increases the demand for petroleum and natural gas products, drilling and oil production and gas production are becoming more and more popular. In addition to strengthening the work of safety and environmental protection, drilling should also adhere to the principle of environmental protection priority, strictly control the links that may cause pollution in production, and achieve strict requirements for green production from drilling equipment to drilling fluid. Potassium formate drilling fluid is an environmentally friendly and high-quality drilling fluid inhibitor product.
The deeper the well is drilled, the more important the drilling fluid is. Potassium formate is widely used and can solve various problems, because it has the advantages of little formation damage, low solid content, broad and tough mud cake, acidification, well cleaning ability, strong inhibition, little environmental pollution, and high temperature stability of polymers.
Potassium formate plays a major role in drilling and completion fluids, and can be completely dissociated. At the same dosage, the effective K concentration is higher than that of potassium chloride, and there is no anionic chloride pollution. The surface tension of filtrate is obviously higher than that of potassium chloride drilling and completion fluids, and the flow resistance of infiltration into formation is large. It not only inhibits clay hydration and dispersion expansion, but also prevents formation shrinkage, but also does not interfere with electrical measurement, and has light corrosion. At the same time, the pollution to oil reservoir is avoided.
Drilling fluid is the "blood" of drilling and plays a very important role in drilling operations. Therefore, the requirement for drilling fluid is very high. Potassium formate in drilling fluid is conducive to improving polymer stability, stabilizing shale, reducing damage to rock formation, ensuring that drilling, completion and oil well maintenance are in the best working state, but also plays a good role in environmental protection and reservoir protection, and achieving green drilling without polluting the environment.
