OPTIMIZATION STUDY ON ELECTRIC HEATING TECHNIQUE BY OIL TUBE
摘要
Abstract
In order to solve the difficulties of easy-to-deposit of the wax, stuck pump, high-energy consumption and so on in the that the borehole lifting of heavy oil, the mathematical model of of the viscosity-reducing and lifting technologies by oil tube electric heating are established with the help of the general principles of heat transferring theory, and furthermore the borehole temperature fields are calculated for the electric heating well, finally the optimized design method for the well are presented. Taking Well A as example, the heated depths and heat powers are optimized for the electric heating system. The obtained most optimized depth is 890 m, the best heat power is 29. 6 kW, the optimized heat-energy consumption is reduced 7.5%; the energy consumptions are reduced by divided different-power heatings in the course of borehole lifting: the heated interval of Well A is evenly divided into 8 sections, and the length of the each section is 111. 25 m, the total heat power is 17. 40 kW. Comparing with the electric heating system with constant power, the energy consumption of the lifting system is reduced 41. 22% , so the energy-saving development of the heavy oil has been further come to ture.关键词
