Problems solved by technology

However, based on foreign technical blockade, they only provide domestic finished materials or parts at high prices, and do not disclose the corresponding technical measures, let alone provide corresponding technical measures, which makes it suitable for domestic deep wells and ultra-deep wells. The high cost of packers increases the technical difficulty and cost of deep and ultra-deep wells in China

Abstract

The invention discloses a high-temperature-resistant and high-pressure-resistant rubber material as well as a preparation method and application thereof. The rubber material is prepared from the following raw materials in percentage by mass: 60-70% of tetrafluoroethylenepr-opylene copolymer, 15-25% of carbon black, 0.5-1% of stearic acid, 5-10% of graphene, 0.5-1% of magnesium oxide, 1.5-2% of dicumyl peroxide, 3-4% of triallyl isocyanurate and 1-2% of triethoxysilane. According to the high-temperature-resistant and high-pressure-resistant rubber material as well as the preparation method andthe application thereof, the components are synergistic and compatible, the prepared rubber material can bear a high temperature of 205 DEG C and a high pressure difference of 105 MPa at the same time, the high-temperature-resistant performance and the high-pressure-resistant performance are excellent, the resistance to a high hydrogen sulfide environment with 20% H2S is achieved, the economic benefits are remarkable, and the application prospect is good.

Description

technical field [0001] The invention relates to a rubber material, in particular to a high-temperature-resistant and high-pressure-resistant rubber material, as well as a preparation method and application of the rubber material. Background technique [0002] As a polymer compound material with the characteristics of elasticity, insulation, impermeability, and airtightness, rubber materials have been widely used in industry and life, including the application of downhole tool packers for oil and gas production. [0003] In oil and gas production, the packer is used to isolate the annular space between the central pipe string and the wellbore, and between the pipe string, so as to isolate the production layer and realize the control of production (injection) fluid. The setting of the packer in the downhole is mainly realized through the rubber sleeve formed by rubber material, and the stability and reliability of the rubber sleeve under the downhole working conditions directl...
