我国是一个拥有13亿人口的农业大国,但是钾盐资源紧缺,多年来对外依存度高达50%以上。在地表盐湖增储潜力有限、海相地层找钾尚未取得突破性进展的情况下,富钾油(气)田水成为解决我国钾资源燃眉之急的首选。近年来,国内在“油钾兼探”方针的指导下对富钾油(气)田水进行了大量勘探、调查评价和研究工作并取得了丰硕的成果。从卤水特点、卤水地球化学和资源评价3个方面总结了前人对柴达木盆地、四川盆地、江汉盆地、塔里木盆地等重要钾盐前景区油(气)田水的研究成果,得出了我国不同盆地油(气)田水资源特点,评价了各盆地油(气)田水研究现状,认为应该重点加强对柴达木盆地西部地区的油(气)田水找钾及研究工作,而且各盆地在油(气)田水资源评价方面研究薄弱,亟需建立油(气)田水资源评价标准与方法。
China is a big agricultural country with a population of 1.3 billion. However, due to its shortage of resources, it has over 50% dependence on foreign countries over the years. In the case of the limited reserves of surface salt lake and the breakthrough of potassium in marine strata, the potassium-rich oilfield gas has become the first choice to solve the urgent need of potassium resources in our country. In recent years, under the guideline of “Oil and Gas Exploration and Exploration”, China has carried out a great deal of exploration, investigation, evaluation and research work on oil-rich potassium (gas) field water and achieved fruitful results. From the characteristics of brine, brine geochemistry and resource assessment, the author summarizes the previous research results on the oil (gas) fields in the foreground oil fields such as Qaidam Basin, Sichuan Basin, Jianghan Basin and Tarim Basin, The characteristics of water resources in oil and gas fields of different basins in China were evaluated. The status quo of oil and gas field water evaluation in each basin was evaluated. It is believed that water-seeking and research work on oil and gas fields in the western Qaidam Basin should be strengthened. The research on water resources evaluation of oil and gas fields is weak in all basins, so it is urgent to establish evaluation criteria and methods for water resources in oil and gas fields.
