  Drilling fluid is called "blood" of drilling. In shale gas exploration in China, the wide use of   potassium formate drilling fluid   has made a breakthrough in deep well drilling with domestic oil-based drilling fluid technology. The PH value has no requirement for the range of potassium formate drilling fluid. The Concept of PH Value of Potassium Formate Drilling Fluid The PH value of the drilling fluid is the PH value of the drilling fluid, which indicates the acidity and alkalinity of the drilling fluid. It is equal to the negative logarithm of the hydrogen ion concentration in the drilling fluid, also known as PH. When the PH is less than 7, the drilling fluid It is acidic. When the PH is equal to 7, the drilling fluid is neutral. When the PH is greater than 7, the drilling fluid is alkaline. The PH of the drilling fluid is usually determined by colorimetry. Effect of PH on potassium formate drilling fluid PH value has a great influence on the performance of potass...

  In drilling engineering, drilling fluid density and mud specific gravity are two equivalent terms. Potassium formate drilling fluid can ensure a very important substance for safe and rapid drilling and protection of oil and gas layers in drilling engineering construction. Let me talk about what the potassium formate drilling fluid does. The popular saying is that when drilling, the drilling pump is pumped into the well from the drill string through the drill bit, and then the fluid that returns to the surface through the annulus. Therefore, the density of   potassium formate drilling fluid   can meet the need of balancing formation pressure. The specific functions are: 1. Carry the drilled cuttings to the ground. 2. Cooling drill 3. Maintain the well wall  4. Establish a pressure balance downhole to prevent formation fluids (oil, gas and water) from entering the well uncontrollably (because formation fluids are under pressure, blowouts occur if the control is not g...

  Previously, drilling fluid was a multi-phase colloidal suspension containing chemical additives, sewage and sewage oil. After the completion of the well in the past, the waste is passed. In terms of ecological environmental protection, drilling fluids are mainly treated by open centralized recovery, curing, exposure, landfilling, etc., which pollute the soil, water and air. At present, in order to reduce atmospheric pollution and improve the environment for oil field drilling, the widely used is   potassium formate drilling fluid , which not only has the advantages of strong suppression, good compatibility, etc., but also non-toxic and non-corrosive. Potassium formate drilling fluid is a kind of inorganic brine drilling fluid system.

  Regarding the impact of modern drilling fluids on the environment, it is recommended that everyone must pay attention to these, these are directly related to the human living environment. The drilling fluid penetrates into the formation with potassium formate, and the flow resistance is large, which not only inhibits the hydration, dispersion and expansion of the clay, prevents the formation from shrinking, but also does not interfere with the electrical measurement. It has light corrosion and avoids pollution to the oil layer. How to distinguish genuine and fake   potassium formate drilling fluid ? The manufacture tells you. When potassium formate is used in drilling fluid, it is generally selected to purchase solids, which is convenient for transportation and more convenient for the preparation of drilling fluid system. Taking potassium formate solid as an example, how to distinguish: 1. The solid potassium formate is white crystal, easy to absorb moisture, and has reducib...

  Well bore stability and borehole rules are the basic conditions for safe, high quality and fast drilling. Drilling fluids with good performances should be able to rely on the battlefield deactivation of liquid phase.   Potassium formate drilling fluid   has high ionic concentration, small free water, low water activity, and the introduction of porous Unstable Strata such as loose, crack development, easy to collapse, water expansion and spalling will greatly reduce the activity of its system, thus giving play to the anti-collapse effect. 1. Banding and Suspended Rock Ridge The drilling fluid prepared by potassium formate is through circulation, bringing the cuttings broken by the bit to the surface, keeping the hole clean, and ensuring that the bit always contacts and breaks the new formation at the bottom of the well. Do not cause repeated cutting, keep safe and fast drilling. Potassium formate drilling fluid can suspend the drilling cuttings left in the well in annulu...

  With the advancement of drilling technology, the drilling speed is accelerated, and the requirements for drilling fluid are more precise. Viscosity is related to the safety factor of construction. The effect of pressure on the apparent viscosity at room temperature is indeed great, but as the temperature increases, the effect of pressure on the apparent viscosity gradually decreases. When drilling into deep formations, the effect of temperature on the apparent viscosity of drilling fluid significantly exceeds the effect of pressure.   Potassium formate drilling fluid   is currently widely used drilling fluid system. The viscosity of the drilling fluid has a great influence on the drilling fluid's ability to carry cuttings. In general, the viscosity of drilling fluid should be determined according to the specific situation. Generally, the viscosity should be low under the premise of ensuring that the cuttings are carried, and the total reflection of the internal friction...

  With the deepening of understanding of the protection of oil and gas layers, reducing the content of solid particles, especially clay particles in drilling fluids, plays an important role in preventing the clogging of the solid particles in the pores of the oil and gas layers and improving the recovery factor. The   potassium formate drilling fluid   can avoid plugging to the greatest extent and improve the productivity of the reservoir. It is also one of the tools to liberate the reservoir. The commonly used drilling fluid for drilling production wells is water-based mud, because the drilling fluid column pressure during drilling is generally greater than the formation pressure. Under the effect of pressure difference, water and clay in the drilling fluid will invade the oil and gas layer, causing various damages to the oil and gas layer. (1) Expand the clay in the production layer (2) Destroy the continuity of oil flow (3) Produce water lock effect and increase oil an...

  The existence of everything is related. Drilling fluid is to improve drilling efficiency and reduce accidents and mining damage to the environment. Potassium formate's inhibitory properties, anti-temperature and anti-pollution properties are actually used in many places nowadays. The use of   potassium formate   mud is conducive to improving polymer stability, stabilizing shale, reducing damage to rock formations, and ensuring that drilling, completion, and oil wells are in optimal working conditions. Drilling fluid is the circulating flushing medium used in the hole during drilling. The effect of the density of potassium formate drilling fluid is actually more reflected in its hydrostatic column pressure. The pressure generated on the ground mainly comes from the three aspects of collapse pressure, pore pressure, and collapse pressure. So when we are working, if the pressure is over nature, it will cause lost circulation. Under normal circumstances, depending on the dr...

The deeper the oil well is drilled, the more important the drilling fluid becomes. Does the drilling fluid need to meet the requirements for protecting oil and gas reservoirs? The answer is yes. The solid-phase  potassium formate drilling fluid  is beneficial to protect oil and gas formations, and will not cause problems such as blockage of oil and gas formations by clay particles and water blocking effect, and will increase the productivity of production formations. Reasons for oil and gas layer damage during drilling: 1. The dispersed phase particles in the drilling fluid block the oil and gas layer; 2. Damage caused by the incompatibility of drilling fluid filtrate with oil and gas reservoir rocks; 3. Damage caused by the incompatibility of drilling fluid filtrate and reservoir fluid; 4. Damage caused by changes in phase permeability; 5. Oil and gas formation damage caused by sharp changes in negative pressure difference. The performance of drilling fluid is closely related...
