In the process of offshore oil exploitation,with the oil well gradually turn to the injection exploitation mode,the crude oil carries a large amount of concentrated oil sludge.These sewage sludge cause serious process and equipment blockage problems in the downstream production system of crude oil,especially on crude oil heaters.In order to solve this problem,the transformation scheme of the heater self-cleaning by using the feed pump pressure difference is put forward,and the self-cleaning of the heater is successfully realized,improving the heat transfer effect and reducing the maintenance cost.This transformation scheme has the advantages of simple operation,low cost,safety and high efficiency,which provides a reference for solving similar problems.This study is of great significance to the operation and maintenance of the offshore oil production plant.
