A self-expanding anti-seepage seal for oil extraction equipment

Abstract

The invention discloses a self-expanding anti-seepage sealing member for oil exploitation equipment, which belongs to the field of oil exploitation equipment, and can realize pertinent setting according to the characteristics of oil. On the one hand, the material is strengthened to improve the oil resistance to oil; on the other hand, the The oil-absorbing parts are actively installed. Once leakage occurs, it can be sensed in time and trigger the specified two-way expansion action. The circumferential expansion can squeeze the water storage material to release the pre-stored emulsifier, emulsify and decompose the oil, and avoid oil damage. The sealing material causes erosion and expands up and down to promote the peristaltic action of the inner expansion cable bag, which then forces the sealing material to expand from the inside to improve the sealing performance and prevent further oil leakage. At the same time, the two-way expansion action has permanent characteristics, so High-efficiency sealing can be maintained at all times, and the sealing performance will not decrease over time, thereby improving the working safety of oil extraction equipment.

Description

technical field [0001] The invention relates to the field of oil extraction equipment, and more specifically relates to a self-expanding anti-seepage seal for oil extraction equipment. Background technique [0002] For special equipment for oil drilling and production, among the faults of mining equipment, there are mainly four types of faults: damage, aging and loose faults, imbalance, and performance failure caused by blockage and leakage, which are manifested as crack corrosion of parts Problems and problems such as strain deformation, cracking and indentation, while aging problems are mainly reflected in the deterioration and aging of materials, wear and peeling, etc., followed by loose faults, which are mainly reflected in the falling and loosening of parts Wait. [0003] Due to the certain corrosion effect of oil, it will accelerate the aging of the seals in the special equipment for oil drilling and production, and it is prone to performance failure caused by blockag...

AI Technical Summary

Problems solved by technology

[0003] Because oil has a certain corrosion effect, it will accelerate the aging of the seals in the special equipment for oil drilling and production, and it is prone to performance failure caused by blockage and leakage. Once such a failure occurs, the equipment will be out of service, and the safety of life and property will occur. , so the safety of high-pressure seals is worthy of attention. In the prior art, the materials of seals are strengthened, such as enhancing the oil resistance of rubber parts, but as time goes by, the performance of seals will inevitably show different degrees. Generally, technicians can effectively avoid this problem by shortening the maintenance cycle and regular maintenance and replacement. However, such strengthening methods are too passive, and the cost is relatively high, requiring huge manpower and material resources
