摘 要
聯合站的設計是以儲運教研室下達的的任務書為依據完成的。該聯合站東西350米，南北250米，年處理量為270萬噸，采用密閉流程。
站外來油經三相分離器、加熱爐、油氣分離器、電脫水器、穩定塔等首先進行油、氣、水的分離，再經外輸泵和計量間等向外輸送。站內氣體直接送往氣體處理廠進行處理。
站內劃分為油罐區，污水處理區，工藝區，配電區，消防區，輔助生產區，設計時設計了有泵流程，同時也考慮了停電流程，即使故流程。
根據任務書所給的站處理量和各種設計參數，首先初步選擇了各工藝段設備，接著確定了總平面布置和聯合站的工藝流程。與此同時，完成了平面布置圖和流程圖，設計并畫了泵房的管線安裝圖。

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
聯合站，即集中處理站，是油田地面集輸系統中的重要組成部分，就是把分散的原料集中、處理使之成為油田產品的過程，油田生產的必要環節。這個過程從油井井口開始，將油井生產出來的原油、伴生天然氣和其他產品，在油田上進行集中、輸送和必要的處理、初加工，將合格的原油送往長距離輸油管線首站，或者送往礦廠油庫經其他運輸方式送到煉油廠或轉運碼頭；合格的天然氣則集中到輸氣管線首站，再送往石油化工廠、液化合格的天然氣則集中到輸氣管線首站，再送往石油化工廠、液化氣廠或其他用戶。就油田的生產全局來說，油氣集輸是繼油藏勘探、油田開發、采油工程之后的很重要的生產階段。
隨著這些年油田采出原油含水率越來越高，聯合站在油田生產中的地位也日益顯得重要。相信在未來的油田的生產中聯合站的地位將會更加重要。
本次設計是更具任務書所給定的內容以及經過大量的計算和論證得出的一套可行的設計方案。
