以改质含蜡原油获得轻质油源的技术为基础，结合对目前重质油开采工艺的分析，提出了原油改质热注采重质油的新工艺。与原油相比，分子筛改质原油粘度、凝点大大减小，油温一般在300～400℃，将其直接注入重质油层，依靠注入介质的稀释作用和热力作用进行开采。依据对采油机理和目前采油工艺的分析，其优点是：采油效果好，注入介质不需要分离，改善了产品品质并给后续原油生产带来利益，因此应用前景良好。 Based on the technology of modifying waxy crude oil to obtain light oil, combined with the analysis of the current heavy oil extraction technology, a new process of reforming hot oil and heavy oil by crude oil was proposed. Compared with crude oil, molecular sieve modified crude oil viscosity, freezing point greatly reduced, the oil temperature is generally 300 ~ 400 ℃, it will be injected directly into the heavy oil reservoir, depending on the dilution of the injection medium and the thermal effect of mining. Based on the analysis of the oil production mechanism and the current oil recovery process, the advantages are: good oil recovery effect, no separation of the injected medium, improved product quality and benefits to follow-up crude oil production. Therefore, the application prospect is good.
