The borehole electric heating technology uses hollow pumping rods instead of one-piece pumping rods, and the built-in heating cable implements the entire heating process under the pump and at the pump, which solves the difficulties of lifting heavy oil, waxing the tubing and lagging the polished connecting rods.

Huaning's electric borehole heating technology solves the problem of complex production in wells with high freezing temperatures and high paraffin content. The high paraffin content and high freezing temperature will cause the well to be blocked and unable to pump out normally, so it must be replaced by a very difficult reservoir test. Pump jamming, pumping rod breakage and mining. The time norm is very low. After the well bore electric heating technology is used in oil production, working conditions can be greatly improved. The electric heating technology of the borehole adapts well to heavy oil with high paraffin content, high freezing temperature and high viscosity.

The heating technology of the hollow rotor screw pump over the pump in the electric well bore heating technology can solve the problem of complex thickening of the oil in the pump. The hollow rotor screw pump heating technology above the pump implements the heating cable above the pump, up and down the pump, and simultaneously heats the whole process.

Hollow Pumping Rod electric heating technology solves severe heavy oil rod hysteresis in inclined vertical wells in heavy oil thermal production. In the production process, due to the high viscosity of crude oil, well deviation and other reasons, the phenomenon of the pumping rod often occurs, and the problems of low timeliness of production and short production cycle are common. In an effort to solve such a problem in the production of inclined vertical wells, according to the specific production situation, Huening has introduced the electric heating technology of the hollow pumping rod, which effectively solved the problem of the polished rod backlog.

Huaning's electric borehole heating technology is easy to process, convenient to design, safe and reliable to operate, fast to operate, and has a longer life than self-controlled temperature heating cables, and the whole set of equipment can be reused for many wells. It is a promising practical technology, and it will continue to develop in the direction of simplicity, safety, high efficiency and energy saving.

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

Long-distance crude oil pipelines with a high paraffin content with freezing temperatures above 50 °C. 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.

What heating product to choose for main infusion pipelines

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.
