摘要/Abstract

摘要： 由于稠油井筒举升与地面集输过程中需要配套环空掺稀油、空心杆电加热或燃气炉加热等降黏工艺,导致稠油开采成本居高不下。根据国内外稠油降黏新技术现状,采用高能纳米波稠油冷裂解技术进行多次现场试验与分析,证实了该技术对稠油的改质降黏作用显著,原油循环处理最大降黏率为81.7%,单次处理最大降黏率为43.7%,初馏点由105 ℃降至81 ℃,330 ℃内总馏分含量提高了5.7%,可实现原油由重质组分向轻质组分的转化。该研究对稠油油藏降本增效具有借鉴意义。

Abstract: In the process of lifting heavy oil in the wellbore as well as gathering and transporting on the ground, it is necessary to equip the viscosity reduction technologies such as thin oil mixing technology in the annulus, electric heating technology of hollow rods, and heating technology of gas furnaces, which leads to high production costs of heavy oil. According to the current status of new viscosity reduction technologies for heavy oil at home and abroad, after multiple field tests and analysis of cold cracking technology with high energy nanowave for heavy oil, it is confirmed that the technology has a significant effect on upgrading and visbreaking for heavy oil. After circulating treatment of crude oil with the technology, the maximum viscosity reduction rate was 81.7%, the maximum viscosity reduction rate of single treatment is 43.7%, the initial boiling point is reduced from 105 ℃ to 81 ℃, and the total fraction content was increased by 5.7% within 330 ℃, which can convert the heavy components into light components in the crude oil. The technology has a great reference significance for cost reduction and efficiency enhancement of heavy oil reservoirs.
