Abstract: Bohai Sea Area is abundant in oil and gas resources. During ten years of exploration, not only a series of large and medium-sized oil and gas fields with relatively small geological structure have been discovered, but some so-called "marginal oilfields" with small-scale and low-grade reserves that are difficult to product economically and efficiently are detected. After constant exploration and practice, some mature development modes for effective development of similar oilfields have been developed. However, these development modes are not applicable for the isolated marginal oil and gas fields near 5m contour in shallow sea area. This paper discusses the problem of which mode could be used for the development of similar oilfields, and brings forward that the artificial island development mode could minimize the time for project construction and drilling & completion and meet the requirements of economic development.

Key words: marginal oilfield, development mode, artificial island

摘要： 渤海海域蕴藏着丰富的石油天然气资源,在数十年的资源勘探过程中,不仅发现了一系列大中型地质构造相对简单的油气田,也发现了一些储量规模小、品位低、难以经济有效开采的所谓"边际油田"。通过不断探索和实践,已经形成了一些比较成熟的高效开发此类油田的开发模式,但是这些已有的开发模式对于位于5m等深线附近,浅海区域孤立的边际油气田并不适用。文章就利用何种模式开发此类油田的问题进行了探讨,指出人工岛开发模式可最大限度地减小油田工程建设和钻完井的时间,满足了经济开发的要求。
