热循环清蜡技术是利用本井的生产液体和伴生气作为抽油井热循环清蜡介质和能源,经加热处理后,注入井内不断循环,在热循环的过程中,添加一定浓度的化学剂,使井内温度达到蜡的熔点,蜡被逐渐熔化并随同油流到地面。该技术在作业过程中,既达到了保护油层、延长油井检修周期的目的,又提高伴生气资源、热能的利用率。该技术应用效果良好,具有操作简单、成本低、不污染油层的特点。 Thermal Cycling Technology is the use of the well production of liquid and associated gas as pumping well thermal recycling waxing medium and energy, after heat treatment, continuous injection into the well, in the thermal cycle of the process, add a certain concentration of chemicals, The temperature in the well reaches the melting point of the wax, and the wax is gradually melted and flows to the ground with the oil. During the operation, the technology not only achieves the purpose of protecting the oil layer and prolonging the overhaul period of the oil well, but also improves the utilization of associated gas resources and thermal energy. The technology has good effect and has the advantages of simple operation, low cost and no pollution to the oil layer.
