在油田开发后期阶段,油井内往往会因为温度、压力等外在条件的原因而使原油中的蜡析出,并且附着在管壁上,堵塞管道,影响油田开发的正常运行。为防止这类问题的发生影响工作效率,必须采用正确的方法对油田开发后期的油井进行清蜡和防蜡工作。本文通过分析油井结蜡的原因,进而探讨出如何正确处理油田开发后期油井结蜡的现象。
In the late stage of oilfield development, the wax in the crude oil often precipitates out of the oil due to external conditions such as temperature and pressure, and is attached to the pipe wall to block the pipeline and affect the normal operation of oilfield development. In order to prevent the occurrence of such problems from affecting work efficiency, we must adopt the correct method to conduct waxing and waxing work on oil wells in the late stage of oilfield development. In this paper, by analyzing the reason of well waxing, the paper explores how to deal with the well waxing in the late stage of oilfield development.
