Theheavyoilwellsof the oil fields(s)oftenrequiretheuseoftheundergroundelectricheateforheating.Duetohightemperature,highpressureandsandabrasion,herequirementsfor the safety, reliability, and service life of the electric heater are very high. 现在推荐的是采用国内近几年新生产的金属MI加热电缆制造的井下电加热器，。电阻性发热，电路系统方式简捷。具有真正的耐高温（可达600℃），机械强度高，热表面负荷低的技术特性。 We now recommended the underground electric heater that is manufactured using the latest domestically made MI heating cable. The product is capable of resistance heating with a simple circuit system. Moreover, it has such technical characteristics as resistance to high temperature (up to 600℃), high mechanical strength and low heat surface load. 井下电加热器可以设计成任意的使用电压，利用井下电加热器的传输电力电缆（采用有成熟应用经验的潜油泵扁电缆），使其既输送电力又能合理沿油管外壁小功率发热。这样的组合，真正解决油井底部粘稠油品的泵吸入加热及油管外壁电加热的技术难题。 The underground electric heater may be designed to any operating voltage. The power transmission cable of the underground electric heater （use the proven flat cable of the submersible pump）is used to transmit power and give off heat at a small power level reasonably along the outer wall of the oil pipe. Such a combination provides a real solution to the technical problems such as pump suction of the heavy bodied oils at the bottom of the oil well and the electric heating of the outer wall of the oil pipe.
潜油泵扁电缆，整根金属铠装，耐高温，耐腐蚀，利用芯线纯电阻来发热成为既导电又发热的特殊优点。绑扎在井内油管外壁上，直至电潜螺杆泵结构需要的封隔器顶端（或者需要的深度），利用市电电压通入潜油泵扁电缆发出的均匀热量直接加热井内油管，通过井内油管均匀加热油管内油品。(可以利用调压变压器升高市电电源电压). The entire flat cable of the submersible pump is metal armored, high-temperature resistant and corrosion-resistant and uses the pure resistance of the core wire for heating and conductivity. Bounded on the outer wall of the oil pipe in the well until the packer top required by the electric submersible screw pump structure (or the required depth) is reached, it uses the commercial power voltage, which is connected to the flat cable of the submersible pump to give off heat evenly to heat the oil pipe in the well, and heat the oil in the pipe evenly through the oil pipe in the well. (The voltage regulator may be used to increase the commercial power voltage). 利用潜油泵扁电缆将市电电压通入井下电加热器（采用金属MI加热电缆制造），发出集中的大功率热量，依靠热对流换热来加热油井下部的油品，以提高油品温度及降低油品粘稠度，方便电潜螺杆泵抽吸油品。 The flat cable of the submersible pump connects the commercial power voltage to the underground electric heater (made using the metal MI heating cable) to give off heat at a high power level in a centralized manner, and the oil at the bottom of the well is heated through convection heat exchange to increase oil temperature and reduce oil viscosity and enable the electric submersible pump to suck up the oil.
