摘　　要：方法利用室内实验．分析了静安堡油田高凝油特性及影响因素。目的通过高凝油特性及影响因素分析，为确定不同类型高凝油油藏合理开发，提供了可靠的依据。结果高凝油的析蜡温度主要受原油中蜡的最高碳原子数、含蜡量及压力的影响；凝固点主要受原油中含蜡量、组分的影响。结论开发高凝油油藏，地层温度应保持在原油析蜡温度以上，地层压力应保持在饱和压力附近。Method This paper analyzes the properties and influence factors of high pour-point oilin Jing'anpu oil field through laboratory method. Purpose To provide reliable basis for rational development of various types of high pour-point oil reservoir through analyzing theproperties and influence factors. Result Wax precipitation temperature of high pour-pointoil is 'lainly influenced by the highest number of carbon atoms of wax in crude oil, wax content and pressure; solidification point is mainly influenced by wax content and component ofcrude oil. Conclusion When developing high pour-point oil reservoir, formation temperature should be kept above the wax precipitation temperature of crude oil, formation pressureshould be kept near the saturation pressure.
