摘要: 高含蜡原油生产时，油井井筒结蜡的影响因素很多也很复杂，仅通过对油样结蜡实验分析或者井筒结蜡厚度的理论分析进行结蜡规律研究比较片面，现场井筒蜡样实验分析及不同气油比压力下结蜡规律实验是必要的补充。以安塞油田高平2井区长10油层原油及蜡样为研究对象，通过黏温曲线测定析蜡温度、原油全组分实验分析、蜡样全组分实验分析、不同气油比和压力条件下实验分析、不同产液量和含水率的理论计算分析等多种手段，全面综合地研究和认识其结蜡规律，为制定清防蜡措施提供了更详实的依据。

Abstract: There are many complex factors which cause wax deposition in wellbore during the high wax content oil production. Therefore, it is not enough to research the patterns of wax deposition only by wax deposition in crude oil testing analysis or calculating the thickness of the wax deposition on the well wall. Comprehensively, it is necessary to do complement research on wax experimental analysis on the well wall in-site and wax deposition pattern study for different GOR oil sample under different pressure. Taking the crude oil and wax from Chang10 reservoir of Gaoping2 district of Ansai oil field as study objective, five aspects are studied to overall analyze and understand patterns of wax deposition: testing wax deposition by viscosity-temperature curve, whole components experimental analysis of crude oil, wax sample whole components testing, wax deposition testing in different GOR and different pressure condition, and wax deposition thickness calculating on the well wall under different produced liquid quantity and produced water cut. Based the results of tests and calculation, wax deposition rules can be summarized comprehensively, which can help to guide projects of preventing and cleaning the wax with production.
