摘要
琼东南盆地深水区是南海西部海域天然气主要发现区。近几年结合亮点识别技术的应用获得多个规模储量发现,但随着深水勘探程度加大,依靠亮点判断含气性的方法面临短板,多口井在强振幅处钻遇干层、水层,亮点不是气层或“甜点”储层的唯一表征,为提高亮点勘探成功率,优选大型储集体,通过对亮点成因解读,建立平点识别、多属性分析、隔夹层识别等勘探评价技术,综合分析目标含气性和储层物性,基于技术应用今年在深水区多个目标获得气层发现,该研究对浅中层勘探具有重要指导意义。
The deep water area of Qiongdongnan Basin is the main discovery area of natural gas in the western sea area of the South China Sea.In recent years,many large-scale reserves have been discovered by combining the application of bright spot identification technology.However,with the increase of deepwater exploration,the method of judging the gas-bearing property by relying on bright spots faces a short board.Many wells have encountered dry layers and water layers at strong amplitude.The bright spot is not the only characterization of the gas layer or sweet spot reservoir.In order to improve the success rate of bright spot exploration,select large reservoirs,and establish flat spot identification,multi-attribute analysis Exploration and evaluation technology such as interlayer identification,comprehensive analysis of target gas bearing property and reservoir physical property,based on the application of technology,gas reservoirs were found in multiple targets in deep water this year.This research has important guiding significance for shallow and middle layer exploration.
