Products Description

NBR50 Downhole Oil Pump Piston Seals

 

Product positioning and use: Specially designed for the piston part of downhole oil pumps, its core mission is to build a reliable sealing barrier in the harsh downhole environment. During oil well exploitation, the oil pump needs to operate continuously and stably. NBR50 seals can effectively prevent well fluid from leaking from the gap between the piston and the pump barrel during the up and down reciprocating motion of the piston, thereby ensuring the efficient operation of the oil pump, maximizing the exploitation efficiency of the oil well and stabilizing the output.

Material properties

Characteristic

Describe

Details

Oil resistance

It has superb tolerance to downhole crude oil and various oil-containing media, has a stable molecular structure, has no swelling or softening after long-term immersion in oil, and has good sealing performance

In heavy crude oil wells with high sulfur content, the volume change rate is extremely small during long-term operation, effectively preventing crude oil leakage.

Wear resistance

Excellent wear resistance, able to cope with the strong friction caused by the frequent high-speed reciprocating motion of the piston in the pump barrel

Under simulated downhole working conditions, the wear amount is reduced by about 30%-50% compared with ordinary rubber seals. The long-term use can maintain the shape and fit of the sealing lip, extend the service life, reduce the number of oil pump shutdowns and maintenance, and improve the continuity of oil well production.

Temperature resistance

Adapt to the wide temperature range of -30℃ to 120℃, not brittle and elastic at low temperature, not soften and deform at high temperature

In actual application of a high-temperature oil well (about 110°C), the seal has been running continuously for more than 8,000 hours, and its sealing performance is stable and reliable, ensuring the continuous high production of the oil well.

Material formulation and quality control

Unique material formula, carefully blended ratio of nitrile rubber and various additives, strict raw material inspection process, multiple processes including purity testing, physical property testing, etc., production follows a strict quality control system, using advanced equipment and technology

Ensure that each NBR50 seal meets uniform and high-standard quality requirements, laying the foundation for stable operation in harsh underground environments

 

Elastic performance parameters

Numerical range

Effect on NBR50 seals

Hardness (Shore A)

About 50 degrees

Balanced sealing and wear resistance to ensure good fit with the pump barrel and no excessive wear during friction

Tensile Strength

10MPa - 15MPa

Withstands large tensile forces without breaking, keeping the seal intact in complex mechanical environments

Elongation at break

300% - 400%

With good elastic recovery, it deforms and recovers quickly with the movement of the piston to ensure a long-lasting sealing effect

Compression set (under certain conditions)

No more than 30% (e.g. 80℃, 24 hours)

Maintain long-term sealing effect and prevent sealing failure due to excessive deformation

Elastic modulus

3MPa - 5MPa

When under pressure, it deforms moderately to fill the sealing gap, and quickly returns to its original shape after the pressure disappears to achieve reliable sealing

   

 

Performance Advantages NBR50 Downhole Oil Pump Piston Seals

 

1. Excellent sealing performance

It can withstand working pressures up to 20MPa. Through special structural design and material enhancement, the sealing performance of NBR50 seals will not decay under high pressure, but will become more stable and reliable. In deep and ultra-deep well mining operations, facing huge formation pressure, NBR50 seals can effectively ensure the normal operation of the oil pump, avoid seal failure and well fluid leakage accidents caused by excessive pressure, and provide solid technical support for deep well mining operations.

 

2. Long life and reliability

Lifespan estimation: Based on a large number of actual application cases and rigorous laboratory accelerated aging test results, under normal downhole conditions, the average service life of NBR50 seals can reach more than 10,000 hours. In some oil wells with relatively good working conditions, its service life can even exceed 15,000 hours. For example, in a medium-sized onshore oil well, NBR50 seals have been running stably for more than 12,000 hours without any downtime for maintenance due to seal problems, which greatly reduced the operating cost and maintenance workload of the oil well.

Reliability verification: The product has undergone a rigorous reliability verification process. In durability tests that simulate various complex working conditions underground, including long-term sealing performance tests under high temperature and high pressure environments, sand-containing well fluid erosion and wear tests, and immersion corrosion tests in formation water with different pH values, NBR50 seals have performed well, and various performance indicators are stable and reliable. Through these rigorous tests and verifications, it is ensured that it can operate stably and reliably in actual oil well exploitation, effectively reducing the risk of oil pump shutdown caused by seal failure, and ensuring the continuity and stability of oil well production.

When the elasticity decreases significantly, the seal should be replaced in time to ensure the normal operation and efficient work of the oil pump.

 

Data comparison and analysis: Compared with oil wells using traditional rubber seals, oil wells using NBR50 seals have an average increase in production of about 15% - 30%. In terms of energy consumption, due to the smoother operation of the oil pump, energy consumption is reduced by about 10% - 20%. In terms of maintenance frequency, it has been greatly reduced from 4 to 6 times a year to 1 to 2 times, which significantly reduces operating costs and maintenance workload, creating higher profit margins and production benefits for oil companies.The quality of this product is top-notch!"

Comparison with similar products

 

1. Performance comparison

Comparison of sealing performance: Compared with fluororubber seals, under the same test conditions, although the leakage rate of NBR50 is slightly higher than that of fluororubber seals, it has more advantages in terms of comprehensive oil resistance and wear resistance, and its cost is relatively low. In terms of pressure adaptability, NBR50 can meet the working pressure requirements of most downhole oil pumps, which is equivalent to fluororubber seals. Compared with polyurethane seals, NBR50 has better temperature resistance and stronger sealing stability in high temperature environments. In terms of wear resistance, the two are similar, but NBR50 performs better in oil resistance and chemical corrosion resistance.

Comparison of other properties: In terms of wear resistance, as mentioned above, the wear resistance of NBR50 is better than that of ordinary rubber seals in the simulated downhole working condition test, and is not inferior to some high-performance similar products. In terms of temperature resistance, its adaptability range of -30℃ to 120℃ can cover most oil well mining environments, which has obvious advantages over some rubber seals with poor temperature resistance. In terms of corrosion resistance, it has good tolerance to common acid and alkali media and sulfur-containing crude oil in the well. In contrast, some rubber seals are prone to aging, hardening or softening when facing strong acid and alkali or high sulfur environments, affecting the sealing performance.

 

2. Cost-effectiveness comparison

- Procurement cost analysis: The procurement cost of NBR50 is slightly lower than that of some high-end fluororubber seals, about 70% - 80%. Although it may not be the lowest in price, it has a high cost-effectiveness considering its comprehensive performance and service life. Compared with some low-priced but poor-performing rubber seals, although the initial procurement cost may be slightly higher, in the long term, due to its long life and low maintenance cost, the total cost is lower.
