The production of oil and gas can lead to creation of wastewater termed as produced water. In certain cases, produced water can be greater in volume than the oil or gas itself. Huge quantities of produced water is presently being discharged by injection into disposal wells, unrecycled. Owing to the limited availability of fresh water, there is a need to investigate alternate sources of procuring water. One such alternative is seawater, which is abundant, but requires treatment prior to usage. However, concerns relating to drought, availability of disposal wells, induced seismicity possibly linked with the disposal well processes, strict regulations on produced water or seawater release into the environment, and challenging water demands, drive the consideration of other means for use or disposal of the circulating water. This article reviews conventional and latest technologies used for the management of produced water and seawater and specifically examines how gas hydrate technology can be used in these areas, in terms of the status, technology, prospects and evolution of its use in treatment of saline water in various concentrations of brine. It is suggested that gas hydrate-based treatment technology might be the future of produced water management; as the reusable produced water can be clean enough for process industries, livestock watering, irrigation and streamflow augmentation; while the treated seawater can be used in producing potable water.

海水和天然气水合物对采出水的处理:回顾

石油和天然气的生产会导致产生称为采出水的废水。在某些情况下,采出水的体积可能大于石油或天然气本身的体积。目前,大量的采出水是通过注入废弃井的方式排放的,未经回收。由于淡水供应有限,因此有必要研究替代性采购水源。一种这样的替代方案是海水,该海水丰富,但在使用前需要进行处理。但是,与干旱,处置井的可用性,可能与处置井过程相关的诱发地震,与产出水或海水向环境中释放的严格规定以及对用水的挑战有关的担忧促使人们考虑使用其他方法来处置或处置废物。循环水。本文回顾了用于管理采出水和海水的常规技术和最新技术,并特别探讨了天然气水合物技术在这些领域中的应用,现状,技术,前景及其在咸水处理中的应用演变。各种浓度的盐水。建议以天然气水合物为基础的处理技术可能是采出水管理的未来。因为可重复使用的采出水可以足够清洁以用于加工业,畜牧业浇灌,灌溉和流量增加;经处理的海水可用于生产饮用水。在各种浓度盐水中处理盐水的前景和发展。建议以天然气水合物为基础的处理技术可能是采出水管理的未来。因为可重复使用的采出水可以足够清洁以用于加工业,畜牧业浇灌,灌溉和流量增加;经处理的海水可用于生产饮用水。在各种浓度盐水中处理盐水的前景和发展。建议以天然气水合物为基础的处理技术可能是采出水管理的未来。因为可重复使用的采出水可以足够清洁以用于加工业,畜牧业浇灌,灌溉和流量增加;经处理的海水可用于生产饮用水。
