摘要
渤海原油储备丰富,随着不断开采,产出液中含水量逐渐上升,且海洋环境保护要求日益提高,如何充分利用海上平台现有设施进行油田产能释放,将面临新的挑战。文章主要论述了随着油田进入中高含水期,传统单平台运行模式导致系统协同性差、提液增产潜力受限,亟须通过跨平台协同优化实现资源高效利用。通过对D平台井口双系列生产管汇进行改造以及中心B和C两个平台一级分离器油相出口管线互联等方式,实现高/低含水井动态切换分输和打通中心B和C两平台原油处理系统,既释放了中心C平台原油处理压力和水处理能力,同时又激活了中心B平台原油处理余量。实现了新老区资源共享,打破传统单平台处理模式,提升了系统稳定性与灵活性。
The Bohai Sea has abundant crude oil reserves.With the continuous exploitation,the water content in the output liquid gradually increases,and the requirements for marine environmental protection are increasing.How to make full use of existing facilities on offshore platforms to release oilfield production capacity will face new challenges.This paper mainly discusses that as the oil field enters a medium-to-high water-bearing period,the traditional single-platform operating mode leads to poor system coordination and limited potential for liquid extraction and increase production,and it is urgent to achieve efficient resource utilization through cross-platform collaborative optimization.By transforming the dual-series production pipelines of the wellhead of the D platform and interconnecting the oil phase outlet pipelines of the first-stage separator of the center B and C platform,the dynamic switching of high/low water-containing wells and opening up the crude oil treatment system of the center B and C platform,which not only releases the crude oil treatment pressure and water treatment capacity of the center C platform,but also activates the crude oil treatment margin of the center B platform.It has realized resource sharing in new and old areas,broken the traditional single-platform processing model,and improved system stability and flexibility.
