Our pursuit to develop offshore marginal oilfields relies on up to date scientific and technological progress as well as modern development management and innovative technologies. China has developed domestically the designed technologies for beach and shallow water areas oil field operations. These technical and engineering systems have been adapted to meet Chinas characteristic, operational features and requirements. Despite of our ongoing efforts, it has not yet met the top international quality standards with regard to the demand for special oil gas bearings and project developments in the middle deep sea areas. The author will analyze the technical shortcomings of beach and shallow water areas exploration engineering, attempts to improve the recovery efficiency, offshore surface engineering technologies, production safeguards etc. A prognosis for the direction and innovate approach used in future management planning and project designs will be given.展开更多
黄河流域生态保护和高质量发展已成为国家战略,对黄河入海口滩区水体范围进行动态监测研究,避免水体演变所衍生出的潜在淹没风险具有重要意义。通过获取长时序丰水期Landsat系列遥感卫星影像数据集,采用基于决策树的多指数陆表水体提取...黄河流域生态保护和高质量发展已成为国家战略,对黄河入海口滩区水体范围进行动态监测研究,避免水体演变所衍生出的潜在淹没风险具有重要意义。通过获取长时序丰水期Landsat系列遥感卫星影像数据集,采用基于决策树的多指数陆表水体提取方法,获取黄河入海口滩区1976—2020年10个研究时点的最大水体范围,并通过叠加分析计算各个区域历史淹没频次,进而识别城镇村庄居民点和采矿用地淹没风险。研究结果表明,10个研究时点中被淹没5次以上的区域为463.7 km 2,以2015年共631个城镇村庄居民点和采矿用地为例,低淹没风险413个,中淹没风险52个,高淹没风险20个。黄河入海口滩区城镇村庄居民点等建设用地应明确迁建需求,科学迁建选址,完善基础设施。展开更多
