How To Choose Electric Heating Cable For Cryogenic Drilling Rig

To ensure normal supply of drilling mud to the manifold in low temperatures, it is necessary to heat the track and preserve the manifold. At present, two heating methods are widely used: steam or hot water and electric heating. The application of electric heating technology in low-temperature drilling rigs can improve drilling efficiency, reduce energy consumption and reduce operating costs, which meets the current requirements of production and development in the energy saving and low-carbon economy.

With the development of the economy, people's demand for oil is increasing day by day, but normal onshore oil resources are decreasing day by day, and the exploration and development of oil resources in the oceans, swamps, deserts, and polar environments is gradually developed. A cryogenic drilling rig is a drilling rig that can perform conventional drilling operations in a low ambient temperature environment (the lowest ambient temperature can reach-45 °C). The drilling manifold is the main pipeline for drilling mud, and the ambient temperature directly affects the quality of the feed, which plays a vital role in drilling operations. To ensure normal supply of drilling mud to the manifold in low temperatures, it is necessary to heat the track and preserve the manifold. At present, two heating methods are widely used: steam or hot water and electric heating.

With a temperature of-20 to 10 ℃, the normal operating time of the drilling rig is longer, and the energy consumption required for heating and heat preservation is smaller. At the same time, for the convenience of control, operation and maintenance, the design uses the electric heating structure. The application of electric heating technology in low-temperature drilling rigs can improve drilling efficiency, reduce energy consumption and reduce operating costs, which meets the current requirements of production and development in the energy saving and low-carbon economy. Mohe's low-temperature drilling rig has an ambient temperature of-45 to 45 °C, the area of use is the pipeline in the pipeline trough with external insulation, and the maintenance temperature is 5 ~ 10 °C. The electric heating cable must have a long service life, especially the electric heating cable can be used according to the pipeline. The output power is automatically adjusted for heat loss, the heating temperature is uniform, the installation and design are convenient, and the maintenance and repair is simple. When the pipeline temperature is kept below 5 ~ 10 °C, the output power of the electric heating belt exceeds the rated power. When the pipeline and environment temperature is higher than 10 °C, the output power of the electric heater Heating belt is less than the rated power. The higher the temperature, the lower the power. Therefore, the self-limiting temperature electric heating belt is selected.

To summarize, it can be said that electric heating has the characteristics of high thermal efficiency, energy saving, environmental protection, simple construction, convenient construction and installation, long service life, remote and automatic control, etc. D. The application of an electric heating cable in the manifold of a low-temperature drilling rig ensures the normal circulation of the drilling mud during the drilling process, and the drilling operation can be performed normally under low-temperature conditions, thus reducing drilling and energy costs.

Electrical heating installation precautions

Electric heating cable is a heating method that uses insulation resistance or resistance heating wire to create a temperature after power supply. It can automatically adjust the output temperature and reasonably maintain the process temperature requirements to keep warm, raise the temperature and protect the heating equipment from freezing. The insulation and antifreeze effect of the container is very good.

Which electric heating should be chosen for the main pipeline transport of heavy oil

Transport of heavy oil through the pipeline over long distances and long-term retention in the pipeline will result in a drop in temperature due to heat dissipation and increased viscosity, which will cause the pipeline to be blocked by freezing or condensation-related accidents. Electric heating is widely used as effective insulation of pipelines and anti-freeze protection.

Which electric heating cable should be considered for a 4 km pipeline

According to the statistics of the Hydrometeorological Center, the average daily minimum temperature at the location of the CNPC tank farm is 5 ° C, and the average daily maximum temperature is 14 ° C. Since the freezing point of the PX is about 15 °C, the supply pipeline needs heat preservation and heating. The oil depot has been in operation for many years without a stable source of steam, therefore, this project is considering the use of electric heating technology.

Application of outdoor electric heating cable in oil main pipelines with high paraffin content

According to the requirements of the production plan of the plant, the volume of oil transportation through the pipeline is 150 thousand rubles. Tons per year, maximum-200 thousand. Tons per year.. According to the thermodynamic analysis of the pipeline, the initial supply temperature of the pipeline is 80 ° C (TN), and the temperature of the end entering the tank is 60 ° C (Tu). Since the transportation temperature needs to be adjusted according to the time of year, it sometimes needs to be transported by heat.

In petrochemical engineering, trunk infusion pipelines are the lifeblood of the factories. The temperature in the northern region is too low in winter and the pipeline needs to be insulated to compensate for the heat loss due to the low temperature in winter to ensure the normal operation of the pipeline.

The role of leather tracer cables in the insulation of asphalt main pipelines

The toughness of the asphalt is greatly affected by the temperature. When the temperature decreases, the toughness of the asphalt increases, and the drop in resistance of the asphalt during pipeline transportation increases; when the temperature falls below the freezing point, the asphalt solidifies, causing the pipeline to clog and the conveyor belt to come to trouble. Therefore, electric heating and heat preservation during the transportation of asphalt are very important.
