论海上边际油田开发的油藏工程研究

RESERVOIR ENGINEERING STUDY FOR OFFSHORE MARGINAL FIELDS DEVELOPMENT

常规的油藏工程研究在开发方案设计中常常由于各种原因带来预测结果不够准确,这对大型油田的开采效果影响不是很大。而海上边际油田一般为小型油气构造,如果采用传统方法对开发效果进行评价,很有可能对边际油田开采价值作出错误的判断。但是海上边际油田总的储量相当可观,具有十分重要的开采价值。在分析海上边际油田开采特征的基础上,探讨了国内外海上边际油田高效开发的一些方法和技术。针对海上边际油田的开发,强调了油藏工程研究在高效开发中的重要性,建议在今后的研究中应通过对边际油田进行现代油藏工程综合研究,制定出最佳开发方案,大力提高我国海上边际油田的开发效益。

Traditional reservoir engineering in field development program, for various reasons, often brings inaccurate prediction results, but these effects do not have great impact on the exploitation of large-scale oilfield. However, for offshore marginal fields, which are generally small oil and gas structures, using the traditional method is likely to make mistakes in judgment. But the reserves of the offshore marginal fields are considerably rich and valuable. This paper, based on the analysis of production characteristics in the offshore marginal fields, has researched the development methods and techniques of offshore marginal oilfield at home and abroad. To the marginal oilfield, the importance of reservoir engineering study in high efficient development is emphasized. In the future,it is important to research the marginal oilfields through modern and comprehensive reservoir engineering and to work out a best plan for improving the efficiency of offshore marginal oilfield development.
