摘要
针对塔河油田的运行状况,为了降低稠油在井筒内的粘度从而降低地面集输系统能耗,开展保温技术研究。实验室测试了九种保温材料的密度、常温及高温下的导热系数、抗压强度及防水性能,结合塔河油田井况,优选出气凝胶涂料,通过建立井筒传热的物理模型和数学模型,构建塔河油田超稠油井筒保温体系,在油管外涂覆6 mm厚的气凝胶涂料可使塔河油田超稠油产出液的出油温度平均升高21℃,全年节能量6.5×10^(8)kJ,达到节能减排,创收增效的作用。
In view of the operating conditions of the Tahe Oilfield,in order to reduce the viscosity of the heavy oil in the wellbore and thereby reduce the energy consumption of the ground gathering and transportation system,the research on insulation technology was carried out.The density,thermal conductivity at normal temperature and high temperature,compressive strength and waterproof performance of nine kinds of insulation materials were tested in the laboratory.Combined with the well conditions of Tahe Oilfield,the aerogel coating is optimized,and the physical and mathematical models of heat transfer in the wellbore are established to construct the ultra-heavy oil wellbore insulation system of Tahe Oilfield.Coating 6mm thick aerogel coating outside the tubing can increase the oil production temperature of the output fluid of the super heavy oil in Tahe Oilfield by an average of 21℃,and the annual energy saving amount is 6.5×10^(8)kJ,so as to achieve the functions of energy saving,emission reduction and income generation and synergy.
