中国石油大学胜利学院 专科毕业设计 (论文) 油井清蜡防蜡工艺的研究及应用 学生姓名: 系 别: 石油工程系油气开采专业 专业年级: 2008级油采3班 指导教师: 2011年5月18日  摘 要 在油田开采过程中,清蜡防蜡工作是油井生产管理的重要环节,由于原油物性及油田开采状况的复杂性,不同区块、不同油井开采的不同时期,油井的结蜡状况也各不相同,油井的清蜡工艺同样需要随时调整。目前,世界上主要的清蜡防蜡工艺有机械清蜡法、热洗清蜡法、磁防蜡、微生物清蜡等技术。 通过对油井结蜡机理、影响因,素、危害以及目前采用的各类油井结蜡治理手段的阐述,研究适合各油井清防蜡方法对今后工作和学习具有深远意义 关键词:结蜡 清蜡 防蜡 ABSTRACT In the course of oil field exploitation, money paraffin wax oil production is an important part of management, because of the physical properties of crude oil and oil field exploration of the complexity of the situation, different blocks, different in different periods of extraction wells, wells wax also varies, wax oil clearance process also requires the adjustment at any time. At present,, the world’s leading anti-paraffin wax paraffin mechanical process ,thermal wax method to clear magnetic anti-wax ,micro wax removal techniques. Wax oil wells through the mechanism of impact , prime, as well as being used against various types of oil wax means of governance that suit the various methods of oil Wax and learning for future work of far-reaching significance Keywords∶ paraffindeposit Wax Removal wax 目 录 论文摘要????????????????????????????????????????????????????????????????1 前言????????????????????????????????????????????????????????????????????1 第一章油井结蜡的机理??????????????????????????????????????????????????? 1 1.1石蜡的性质???????????????????????????????????????????????????????1 1.2影响油井结蜡的因素???????????????????????????????????????????????2 1.3油井结蜡造成的危害???????????????????????????????????????????????4 第二章国内各种清蜡防蜡的方式及使用介绍??????????????????????????????????5 2.1机械清蜡技术?????????????????????????????????????????????????????5 2.2热力清蜡技术?????????????????????????????????????????????????????17 2.3强磁防蜡技术?????????????????????????????????????????????????????10 2.4油管内衬和涂层防蜡技术???????????????????????????????????????????12 2.5化学清蜡防蜡技术??????????????????????????????
