Humic acid type fluid loss additive is a type of polymer oil well cement fluid loss additive that has been gaining popularity in recent years. As one of the innovative products of Oilbayer, a company that specializes in the R&D and manufacturing of oilfield chemicals, this fluid loss additive has been designed to help oil and gas operators in the quest for maximum productivity and efficiency.
This type of additive is typically made from a combination of AMPS/NN/humic acid with good temperature and salt resistance. The humic acid acts as the main monomer, while other salt-resistant monomers are combined to enhance its effectiveness. The result is a highly effective additive that can help reduce fluid loss during well cementing, thereby optimizing the well's performance and improving the overall return on investment.
Fluid loss is a common problem in the oil and gas industry, particularly during cementing operations. It occurs when the fluid used to cement the wellbore seeps into the rock formation, leaving voids that reduce the strength of the cement bond. This can lead to a number of issues, such as reduced productivity, increased maintenance costs, and even well integrity problems.
Humic acid type fluid loss additive helps to mitigate these problems by forming a protective layer around the wellbore. This layer acts as a barrier, preventing the cement fluid from seeping into the formation and reducing the amount of fluid that is lost during cementing operations. This is achieved through a combination of the polymer's unique properties, which help to increase the viscosity of the cement fluid and prevent it from flowing into the wellbore.
One of the main advantages of using humic acid type fluid loss additives is their excellent temperature and salt resistance. This means that they can be used in a wide range of environments, including high-temperature formations and those with high salt concentrations. This versatility makes them an ideal choice for oil and gas operators looking to maximize the efficiency and productivity of their drilling operations.
In conclusion, humic acid type fluid loss additive is an innovative solution to the fluid loss problems experienced by the oil and gas industry. Developed by Oilbayer, this product combines the unique benefits of AMPS/NN/humic acid with other salt-resistant monomers to create a highly effective additive that can be used in a wide range of applications. If you are interested in improving the productivity and efficiency of your drilling operations, consider incorporating humic acid type fluid loss additive into your cementing operations.
MEDIUM AND LOW TEMPERATURE POLYMER FLUID LOSS REDUCER
Polymer oil well cementing technology has been widely used in the exploration and development of oil and gas fields. One of the important components in polymer cementing technology is the anti-water loss agent, which can reduce the water loss rate during the cementing process. The use of polymer cement technology has many advantages such as high strength, low permeability, and excellent sealing performance. However, the common problem encountered in this process is water loss, that is, the cement slurry seeps into the formation, making it difficult to pull out the tube during oil recovery. Therefore, the development of medium and low temperature fluid loss reducer has become the focus of oilfield cementing technology progress.
Polymer oil well cement fluid loss reducer:
Fluid loss additive is an indispensable raw material for preparing cement slurry. It is a powder that is readily soluble in water and has good mixing properties. During formulation, fluid loss control agents are mixed with other components to form a homogeneous and stable cement slurry. The fluid loss control agent plays a vital role in reducing the fluid loss rate during the cementing process. It reduces the migration of water in the mud to the surrounding formations and improves the mechanical properties of the cement.
Water loss ≤ 50:
When using fluid loss reducing agents, it is important to control the fluid loss rate within a certain range, usually less than or equal to 50ml/30min. If the water loss rate is too high, the cement slurry will seep into the formation, causing borehole channeling, mud, and cementing failure. On the other hand, if the water loss rate is too low, the cementing time will be increased, and an additional anti-water loss agent is required, which increases the process cost.
Medium and low temperature fluid loss reducer:
During the cementing process in oilfields, the water loss rate is affected by various factors such as formation temperature, pressure, and permeability. In particular, the temperature of the cementing fluid has a significant effect on the fluid loss rate. Fluid losses tend to increase significantly at high temperatures. Therefore, in the cementing process, it is necessary to use medium and low temperature fluid loss additives that can reduce the fluid loss rate at high temperatures.
In summary:
In short, polymer oil well cementing technology has become one of the essential technologies for oil and gas field exploration and development. One of the key components of this technology is the anti-water loss agent, which plays a vital role in reducing the water loss rate during the cementing process. Control of water loss during mud preparation also plays a vital role in ensuring the success of the cementing process. The development of medium and low temperature fluid loss reducers is of great significance for improving cementing efficiency, reducing costs and improving the integrity of oil and gas wells.
