Product Name: oil self-limiting temperature heating cable Product name: (ZR) DWK-J DWK-PF Usage: heating oil pipeline, auxiliary heat six Specifications: Product Name Model Specifications Power (W / m 10 ℃) work Voltage (V) Maximum length (m) (flame retardant) low basic type (ZR) DWK-J 15,20,25,30,65 6 ~ 380 100 (flame retardant) low protection type (ZR) DWK-F 15 , 20,25,30,65 6 380 100 (flame retardant) low temperature explosion-proof (ZR) DWK-P 15,20,25,30,65 6 ~ 380 100 (flame retardant) low temperature explosion protection type (ZR) DWK -PF 15,20,25,30,65 6 ~ 380 100 (flame retardant) low Explosion-proof type (ZR) DWK-PF2 15,20,25,30,65 6 ~ 380 100 around the thermal recovery of various heat process equipment have been used. Such as: electric heating rods, heating frequency, constant power heating cable or rod tube heat cable (short high current law) electric heating rod heating means (so-called skin effect method), underground electric stove and underground infrared heating and hot chemical method and the like. To sum up each method has achieved some positive results, but after investigation analysis of the unit after the trial, there is a problem: 1, the control device failure and more complicated, inconvenient operation. Through power outages due to temperature, since the number of lifetime limits off, once failure could easily lead to cable overheating, even major accidents (especially gas). 2, as is the constant power, high power, high energy consumption, but not with downhole temperature gradient along the heat and adjust the gradient. Therefore, in addition to increasing the secondary costs, more suitable for large area. 3, due to the presence of constant power can not overcome the irrational product structure design, so life is short, usually no more than six months, it will take to repair or replace, the actual cost is not significant. 4, all means complicated, installation, construction, maintenance inconvenience. 5, long-term use of thermochemical expensive oil, while oil pollution, increase follow-up costs of production, only applies in one portion. Features an effective role in the self-regulating heating cable oil mix An electrical heating device such as the production of all of the above are having a thermal recovery methods, while addressing the above problems, is currently the more advanced an effective means of technology, the effect is very ideal. And because it's energy efficient for widely used. Seven hot mix well since the temperature control cable wellbore heat means it works: Hefei-oil mix as self-regulating heating cable electric heating device is self-regulating heating cable is energized mix well after the pipeline along the direction of the temperature gradient with depth Reverse automatically adjust the output power. Tubing through the tubing to heat the outer wall, along the route to maintain a certain temperature, to achieve the viscosity, the solution was wrong, the effect of increasing the pump efficiency. Its core is the hot cable with three sets of PTC heater band is processed by extrusion radiation made of a conductive polymer PTC functional materials, have encountered each point with a change in temperature is heating system adverse change with output power to achieve automatic compensation, automatic adjustment, automatic control of the effect. Eight, the main characteristics: to provide the necessary heat for the production tubing, the oil temperature is maintained at above the critical point of waxy crude oil and heavy oil. Self-adjusting variable output power so self-regulating heating cable designed to achieve best value for money. Controlled performance makes tubing does not overheat, no hot spots or due to changes in well conditions can cause blown phenomenon. Self-Regulating technology allows each point corresponding to the heating cable is heating system due to temperature changes at each point can be self-adjusting power. With the increase of the temperature of the tubing, heating cable automatically reduces heat output, and vice versa. In this way hot mix cable will continue to compensate for temperature fluctuations, while the conventional electric heating wire (constant power) is easy to produce local overheating and burned. Controlled performance to better meet the specific requirements of each well, continuous or repeated use, but also because of the need for further energy saving well conditions, especially regular wax and intermittent use. Nine, the main advantages: Economy: easy installation and optimum effectiveness depending on the specific design of the heating system well. The system in the following manner to produce immediate effects on crude oil production: A, reduce pipeline blocking wax and frequent scraping wax to stabilize production. B, raised temperature viscosity decreases wellbore flow resistance increase pump efficiency. C, reducing the pumping load, extend column pump cycle. Easy to control: Heat oil heating cable output can vary according to the needs of their own, so that operating costs low, after a temporary shut-in tubing are not blocked, can quickly restore oil production capacity. While low-flow does not produce crude oil pipeline phenomenon partially blocked. Does not pollute the crude oil, both can get the full value of the production of crude oil, it will not affect the treatment process downstream refining a schematic circuit diagram (see Figure 1).
