| 摘 要： | 辽河盆地兴隆台、黄金带等油田拥有丰富的浅层天然气资源,利用时间推移放射性测井技术可以在老油田发现老井遗漏的未解释气层,判断已解释气层的泄压、水淹状况,以及发现因钻井污染而遗漏的气层。通过中子伽马测井技术的应用,在兴隆台油田发现了大量的浅层气,并已取得很好的开发效果,指导了老油田的天然气挖潜方向。

| Abstract: | Xinglongtai and Huangjindai oilfield in Liaohe basin are rich in shallow gas resources. By using time lapse radioactive logging technology, the un- interpreted gas layers missed by old wells in old oilfield can be discovered, the status of the interpreted gas layers which is blow -down or water - flooded can be determined, and the missed gas layer for drilling - contamination can be detected. Through the application of neutron - gamma logging in Xinglongtai Oilfield, a great deal of shallow natural gas has been found out. The effective application provides useful guidance for potential direction of natural gas in old oilfield. |
