中国石油大学胜利学院毕业论文 关于油井清防蜡技术的研究 学生姓名：王宇斌 学 号：200810023308 专业班级：石油工程08—3班 指导教师：谭胜利 2011年 6 月 20 日 毕业论文任务书 一、题目 关于油井清防蜡技术的研究 二、本课题研究的目的、现状、工作任务和预期目标 我国油田含蜡原油产量较大。当含蜡原油温度低于蜡的初始结晶温度 时，蜡晶微粒便开始在油流中和油管内壁及抽油杆上析出，原油黏度急剧增 加，随温度不断降低，析出蜡晶的数量增加，使我们的油井经常发生蜡卡， 这样便要作业施工进行检泵，那样所花费的成本将会大幅度的提高了采油成 本，使我们采油工作的生产效益降低，因此清、防蜡是含蜡原油开采中需要 解决的重要问题。本课题从分析影响结蜡的因素及及结蜡产生的机理出发， 通过调研江汉油田ABOUT OIL WELL CLEAR AGAINST WAX NOLOGY RESEARCH ABSTRACT our counry oi1 field to contain the wax q uantity crude oi1 output to be bigger．Because the oil wel1 frequently has the wax card phenomenonin the crude oil production process，1ike this creaates the result is exacts oi1 the cost excessivel y high，in order to pursue the biggest economic，therefre is c1ear to the oi1 we11，guards against the wax research is ext remely urgent．This article from affects the wax the factor，the wax process embarks，clear guarded against the wax to the oi1 wel1 to perform the detailed research trial， and through the oil field experiment has obtained the better government countermeasure to Wei River north as follows: (1)，the production initial potentialhigh，contain swater the low wel1 to be possible to use adds the medicament own loop， regular(quarter or half year)when own end of 1oopin，forextracts fromanoi1 well wit h the high lukewarm water the wax，the effect best，quite is also economica1． (2)，the production intermediate stage and the laterperiod suitablly adopt in safeguards the good oi1 ayer in the foundation， usualiy note the regular Canadian medicine to guard against the wax：According to cyclical high temperature hot water.Key word:Clear guards against the wax:Technology； Effect. 目 录 论文摘要…………………………………………………………………………I 第1章 前言……………………………………………………………………….1 第2章油井的清蜡与防蜡技术概述……………………………………………..1 2．1蜡的定义与特性…………………………………………………………….1 2．2影响结蜡的因素…………………………………………………………….2 2．2．1原油性质对结蜡的影响……………………………………………….3 2. 2．2一温度对结蜡的影响………………………………………………
