摘　　要：针对目前有些进入中后期开发的油田接卸原油大多采用开式或半密闭工艺,不能满足国家法规污染物排放要求的问题,在简要介绍了开式和半密闭卸油工艺的基础上,设计了一套全密闭卸油工艺流程,运用PLC实现对卸油过程实施PID闭环控制,实现卸油泵自动启停和全自动密闭卸油。通过对某联合站卸油工艺的改造,可比半密闭卸油减少原油损耗0.48t/d,天然气0.175t/d,全年实现经济效益115万元,投资回收期约为0.79年,既达到了环保要求,又消除了安全隐患,在获得较好经济和社会效益的同时,对油田生产具有重要意义。Aiming at the problem that the open or semi-closed process is mostly used for oil unloading in oilfields at present,which cannot meet the requirement of pollutant discharge in national regulations,based on brief introduction of the open and semi-closed process of oil unloading,a fully closed process of oil unloading is designed in which the automatic start and stop of oil pump and fully automatic closed unloading can be achieved by using PLC to realize the PID closed-loop control of oil unloading process.Through the revamp of the unloading process in a combined station,a large amount of crude oil and natural gas can be recovered.The annual economic benefit is 1.15 million Yuan with the payback period of 0.79 years.It can not only meet the requirements of environmental protection,but also eliminate the potential safety hazards.At the same time,it reduces the waste of energy and achieves better economic and social benefits.
