摘要
油井出砂不仅导致了沉降罐等设施的效率下降和使用寿命的缩短,影响油田的正常生产;而且由于泥砂含油,直接外排造成环境污染和能源浪费.为了减小以上弊端,通过对多种清砂方法的分析比较,确定了大罐沉降和旋流除砂二级流程的新方案,成功设计了一套油罐自动清砂工艺装置.该装置由油罐清砂装置、密闭清砂道和旋流洗砂装置组成.对该装置的工艺流程、原理、设计依据进行了较为详细的介绍.现场应用表明该装置运行平稳,清砂效果非常显著,取得了良好的经济效益和社会效益.
In our country,the reserves of sandstone oilfields is great and the distribution of them is extensive.With the exploitation of the oilfields,the sand production rate graduate increases.The deposition of sand makes the efficiency of settling tanks decline and working life shorter,which affects the regular production of oilfields.There is oil in sand,and which results in polluting environment pollution and resource waste.In order to solve the problems above,a two-stage desanding scheme of settling desanding and swirling desanding is determined and a set of automatic desanding equipment for oil tank is designed by the comparison and analysis of several desanding means.The equipment is composed of oil tank desanding part,closed desanding channel and centrifugal sand washing part.Field test shows that the equipment runs well and desanding result is satisfying. Good economical and social benefits are obtained.
