Description

TECHNICAL FIELD

[0001] The utility model relates to is well structure technical field, specifically speaking, especially, a kind of anti-freezing heat preservation steel well. BACKGROUND

[0002] In the development and utilization of petroleum chemical industry, natural gas and other resources, steel well as basic pipe network facilities, is crucial to ensure the stable and efficient development and transportation of resources.In cold regions, its thermal performance becomes a key factor in determining resource utilization and facility operation stability.However, traditional steel well has many problems to be solved in thermal insulation.

[0003] The thermal insulation effect of traditional steel well body is poor.In cold environment, equipment and liquid in well are easily affected by low temperature outside.When the temperature is too low, the liquid transported in the well may freeze, causing pipe blockage, seriously affecting resource transportation efficiency, and even causing production accidents.At the same time, low temperature will reduce the performance of equipment in well, shorten the service life of equipment, increase maintenance cost and frequency.For example, in the oil and gas field in northern China, the winter temperature often reaches minus 20 to 30 degrees Celsius, and the valves, instruments and other equipment in the traditional steel well often malfunction, and maintenance personnel need to frequently go downhole for repair, consuming a lot of manpower, material resources and time cost.

[0004] The existing thermal insulation materials applied to steel well have complex construction process.Some thermal insulation materials need to be wound, pasted or poured on site, which requires high technical requirements for construction personnel and high construction difficulty.Furthermore, these complex construction processes are easily disturbed by environmental factors, such as in rainy and snowy weather, the construction quality is difficult to guarantee, and the construction period is long, which increases the time cost of the project.Some steel well projects that use on-site pouring of thermal insulation materials need to consume several days of time for the thermal insulation construction of an ordinary steel well, which seriously affects the engineering progress.

[0005] The traditional thermal insulation method is high in cost.From the procurement of thermal insulation materials, the price of some high-performance thermal insulation materials is high, which increases the initial investment of the project.Furthermore, due to the limited thermal insulation effect, a large amount of energy needs to be consumed to maintain the temperature in the well, resulting in high long-term operating cost.In addition, frequent equipment maintenance and repair further increase the total cost.According to statistics, the sum of energy consumption and maintenance cost of steel well using traditional thermal insulation method can reach several times of the cost of newly built steel well in the service life of equipment.

[0006] Therefore, it is of great significance to develop a steel well with excellent thermal insulation performance, convenient construction and reasonable cost.The anti-freezing heat preservation steel well is designed to solve the above industry pain points, and is committed to improving the efficiency of resource development and utilization, and reducing energy consumption and cost.
