虚拟开发技术及其在渤海稠油油田开发中的应用

The Application of Virtual Development Technique in the Development of Bohai Heavy Oil Oilfield

针对渤海常规稠油油田开发效益较低的问题,提出应用虚拟开发技术来指导未开发油田的总体开发方案编制和已开发油田的调整。认为储量动用策略、井型选择策略、产能设计策略和阶段调整策略是渤海稠油油田开发所应采用的主要策略。以孤东七区中为虚拟开发研究对象,共设计了15个虚拟开发方案,并对其进行了开发效果评价和经济效益评价,确定了经济效益最好的方案和开发效果最好的方案。

In consideration of the problem of low efficient development of conventional heavy oil in Bohai Oilfield, a virtual development technique is proposed to guide the creation of overall development schemes for undeveloped oilfields and adjust of developed oilfield. It is considered that the strategies of reserves producing, well selection, productivity design and periodic adjustment are the principal strategies for heavy oil production in Bohai Oilfield. Based on the middle of Well Block Gudong 7,15virtual development schemes are designed,an evaluation is conducted on its development effect and its economic benefits, the schemes for best beneficial efficiency and best production effect are determined.
