摘 要
联合站的设计是以储运教研室下达的的任务书为依据完成的。该联合站东西350米，南北250米，年处理量为270万吨，采用密闭流程。
站外来油经三相分离器、加热炉、油气分离器、电脱水器、稳定塔等首先进行油、气、水的分离，再经外输泵和计量间等向外输送。站内气体直接送往气体处理厂进行处理。
站内划分为油罐区，污水处理区，工艺区，配电区，消防区，辅助生产区，设计时设计了有泵流程，同时也考虑了停电流程，即使故流程。
根据任务书所给的站处理量和各种设计参数，首先初步选择了各工艺段设备，接着确定了总平面布置和联合站的工艺流程。与此同时，完成了平面布置图和流程图，设计并画了泵房的管线安装图。

ABSTRACT
The design of WH Central Treating Station was complicated according to the assignment given by the Storage and Transportation Teaching and Researching Department. It is 250 meters long from north to south and 350meters wide from east to west. The treating capacity of the station is about 2,700, 000 tons per year.
The central treating station treats well stream. Its main task is oil, gas and water separation. Gas, crude oil and water mixture flow into the central treating station. First, it goes into three phase separators, then goes through fluid jacket heaters, Two phase separators, electronic dehydrators, stabilization tower ,at last treated crude oil is pumped to the mineral terminal.
The central treating station includes two main processes, they are tight flow process with and without pumps. In addition, the accidental process while power is off was considered.
In the design, we considered the conditions given by the assignment; seclected and checked the equipments and pipelines.The design include three draws.

前言
第一章 前言
联合站，即集中处理站，是油田地面集输系统中的重要组成部分，就是把分散的原料集中、处理使之成为油田产品的过程，油田生产的必要环节。这个过程从油井井口开始，将油井生产出来的原油、伴生天然气和其他产品，在油田上进行集中、输送和必要的处理、初加工，将合格的原油送往长距离输油管线首站，或者送往矿厂油库经其他运输方式送到炼油厂或转运码头；合格的天然气则集中到输气管线首站，再送往石油化工厂、液化合格的天然气则集中到输气管线首站，再送往石油化工厂、液化气厂或其他用户。就油田的生产全局来说，油气集输是继油藏勘探、油田开发、采油工程之后的很重要的生产阶段。
随着这些年油田采出原油含水率越来越高，联合站在油田生产中的地位也日益显得重要。相信在未来的油田的生产中联合站的地位将会更加重要。
本次设计是更具任务书所给定的内容以及经过大量的计算和论证得出的一套可行的设计方案。
