Problems solved by technology

In this patented technology, the proportion of nitrile rubber is only 4-6wt%, and the addition of carbon black is also reduced to about 10%, which improves the safety performance and cost of the rubber material, but although the rubber material has certain wear resistance , but for more complex oil well production, its strength still needs to be further improved, and its oil resistance is relatively poor, and it is very easy to have serious corrosion performance during the production process

Abstract

The invention discloses a screw pump stator rubber material and a preparation method thereof. The stator rubber material comprises the following raw materials in parts by weight: 100-200 parts of natural rubber, 50-80 parts of polyolefin fluororubber, methyl vinyl silicon 3-15 parts of rubber, 10-20 parts of reinforcing agent, 3-5 parts of vulcanizing agent, 1.0-3.5 parts of crosslinking agent, 0.5-1.0 parts of accelerator M, 0.3-0.5 parts of plasticizer, 0.2-0.5 parts of anti-aging agent part, 0.3-0.5 part of stearic acid SA, the reinforcing agent adopted is composed of calcium silicate, lignin, calcium carbonate and kaolin; the vulcanizing agent adopted is composed of nano zinc oxide, nano magnesium oxide, chlorosulfonated Polyethylene and neoprene composition. The screw pump stator rubber material of the present invention has high oil resistance, corrosion resistance, wear resistance and high temperature resistance, and at the same time, the stator rubber is low in cost, easy to process, suitable for operation in different oil well environments, and has a long service life.

Description

technical field [0001] The invention relates to the technical field of rubber material processing, in particular to a screw pump stator rubber material and a preparation method thereof. Background technique [0002] Progressive cavity pump oil recovery technology is the main mechanical recovery method in oilfield exploitation at present. The screw pump has a simple structure, is suitable for oil wells with high viscosity and high sand content, and has high working efficiency. Single screw pumps are mostly used in various booster stations and transfer stations, and the conveyed medium is generally untreated crude oil and oil-water mixture. This kind of liquid has the following characteristics: the sediment and impurities are particularly large, and the rubber is severely worn; the liquid contains a large amount of saline and alkali, which seriously corrodes the rubber; the conveyed medium comes from different layers, causing serious scaling inside the screw pump. ;The conve...
