南海西部海域有数十个未开发边际油田,采用常规开发模式和技术难以投入生产。为了经济有效开发这些海上边际油田,分析了制约南海西部海域边际油田开发的主要因素:地理环境、基本地质条件、储量规模和评价程度,探讨了边际油田开发的有利条件,包括当前的高油价、开发技术发展、本海域油田开发实际模式和经验等,在此基础上总结了一套适合南海西部海域边际油田开发的基本思路,即勘探开发一体化、合理开发模式、先进开发技术、少井高产和借鉴已开发经验,并在涠洲油田群、文昌油田群具体实施。开发实践表明,开发思路和技术合理有效,开发效果和经济效益十分显著。对于类似边际油田开发具有重要的借鉴和指导作用。

There are tens of marginal oilfields not developed in the western South China Sea because it is difficult to produce by conventional development mode and technique.In order to develop the offshore marginal oilfield economically and effectively,main affecting factors of restricting marginal oilfield are analyzed,including geographic environment,basic geologic condition,reserves scale,evaluation degree and so on.The favorable conditions including high oil price at the moment,advance of development technology,practical pattern and experience of oilfield development in this sea area and so on are investigated.Based on the said,a set of basic idea fit for the development of marginal oilfield in the western South China Sea is concluded.That is,exploration and development integration,reasonable development mode,advanced development technology,fewer wells high yield and using developing experience.And specific application is done in Weizhou oilfield group and Wenchang oilfield group.The development practice shows that the idea and technology of development is reasonable and effective and makes remarkable development effects and economic benefits,which is of importance reference and guidance for such marginal oilfield development.
