- 摘要:
- 冀东油田大多数油井原油的沥青质-胶质和蜡的含量都较高,在生产过程中存在3方面的问题:由于结蜡,产量不稳定;原油黏度大,用通常的采油技术工艺无法生产;地层堵塞,产量逐渐下降,甚至变成死井.为解决这些问题,研究开发了油井清防蜡剂、原油降黏剂,地层解堵剂,文章介绍了研究过程及试验方法.现场应用表明,冀东油田仅1993年使用BJ-5油基降黏剂、BJ-7清蜡剂和HJ-2解堵剂后,全年增产原油超过20690t,创经济效益2160多万元.
the content of asphaltic and waxen paraffin are mostly very high in the crude oil of Jidong oilfield,therefore,in some areas the yield are i-nstable because of the paraffin,some wells can't be on steam because of the high viscosity of the crude oil,and there are still others that the yield are reducing so much as dead wells because the formations are plugging.In order to solve these problems,the crude oil paraffin inh-ibitor and remover, the crude oil visbreaking agent and the formation blocking remover are developed.The developing process and the experime-ntal method are presented here.2005,S1(S1): 6-10 收稿日期：2005-3-7分类号：TE358.2作者简介：陈伟君( 1954-),女,浙江人,毕业于华北石油学校,工程师,现任冀东油田采油工程处综合主管.
