BZ34-3／5边际油气田有效开发工程关键技术及其应用

The critical technologies and their application in Bozhong 34-3/5 marginal oilfields development engineering

BZ34-3/5属于边际油气田,采用常规的开发工程技术和结构平台无法实现有效开发。流体保障技术的首次应用和井口保护架技术、子母管置换技术、高低压混输海底电缆技术、安全简易自动控制技术、适宜登乘结构技术的研发与成功应用,很好地解决了BZ34-3/5边际油气田开发中所面临的主要技术难题,取得了良好的经济效益,也为海上边际油气田开发提供了一种简易、快捷、有效的开发模式。

BZ34-3/5 oilfields can be defined as Small marginal oilfields, so that conventional technology and platform are unable to be utilized in efficient oilfield development. In order to solve the technological problem BZ34-3/5 faced and make BZ34-3/5 economically profitable, we initially applied Fluid Assurance Technology and developed Wellhead Safeguard Technology, Composite Pipeline Replacement Technology, Submarine Cable HV＆LV Power Transmission Technology, Safety Auto- Control Technology and Easily Mounted Strut ture, which provide a simpler, more efficient and effective method for the marginal oilfield development.
