Our company has been engaged in the production and research and development of petroleum drilling and production equipment and accessories since its establishment in 2007, and is committed to the research and development of packing boxes. We have achieved many results in production, and the multifunctional energy-saving packing box is one of the new series of oil well wellhead sealing devices developed by our company.
This product has a unique design, simple operation, and is safe and reliable. The main advantages of the product are as follows:
1. Equipped with automatic dual deviation adjustment function. High alignment rate reduces excessive wear of the packing caused by eccentric wear and prolongs its service life, such as The deviation of the wellhead is too large, and manual deviation adjustment function can also be used
2. High pressure. This product can withstand a maximum static pressure of 37MPa, greatly improving the safety level of pressure resistance, and has a strong sealing effect to prevent oil leakage
Safety hazards caused by gas leakage; When acidizing the oil well with a pump, the good pressure resistance of the product can be utilized, while ordinary packing boxes can Due to work wear and tear, the sealing performance has greatly decreased.
3. High power saving. Due to its automatic lubrication device, this product prevents hard friction between the polished rod and the packing, greatly reducing the wear of the polished rod Degree and reduced energy consumption.
4. Long service life. Due to the use of patented product - carbon silicon sealing element - as the sealing material of the multifunctional energy-saving packing box, patent number:CN03266169. X; It has the characteristics of wear resistance, heat resistance, high pressure resistance, and strong plasticity, greatly reducing the replacement cycle of the packing.
5. Adapt to a wide range of work environments. The working environment of carbon dioxide huff and puff wells is complex and highly corrosive. Ordinary packing boxes are used here Its physical performance is greatly compromised in the environment, unable to effectively seal and meet work requirements. This product is fully suitable for work due to its unique design
Environment: When the working temperature of the high-temperature steam injection well reaches 260 degrees or above, ordinary packing boxes and packing lose their plasticity and rapidly age when exposed to high temperatures
The product can meet the environmental temperature requirements for high-temperature steam injection.
6. In response to the serious corrosion and wear of the polished rod caused by long-term non lubrication friction and complex underground media in water injection wells,Causing short service life and inability to seal ordinary packing boxes. Our company designs a buffered structure inside the product, which reduces the cost
The high-strength friction between the bare rod and the packing prevents direct compression and wear between the packing and the bare rod, and has the characteristics of energy conservation and environmental protection.In summary, using our company's products can effectively solve the above problems, prevent leakage, and maintain a long-lasting seal. Packing replacement cycle Long, usually the disc root only needs to be replaced once or twice a year (it can be used for a long time after following the standard process); Simultaneously reducing downtime
The number of wells increases the production of oil wells, indirectly reducing the phenomenon of pump blockage caused by well shutdowns, and reducing maintenance costs such as well flushing and pump inspection caused by pump blockage;At the same time, it greatly reduces the labor intensity of oil extraction workers, improves labor efficiency, saves oil extraction costs for the oil field, and obtains consistent user satisfaction Positive feedback and praise.
This product is currently a new patented product with advanced functions in China, and has obtained three patents:
Smooth rod sealing device, patent number: ZL2010 2 0167267;
