为了优化古流体压力恢复的技术途径,结合国内外的研究进展对盆地中古流体压力的恢复方法进行了梳理、分析和讨论.恢复方法主要包括泥岩声波时差法、盆地模拟法和流体包裹体法.泥岩声波时差法廉价、快速,但只能恢复最大埋深时的古流体压力,而不适于欠压实以外其他异常压力形成机制；盆地模拟方法可恢复压力的演化史,但其地质模型复杂、参数繁多且不确定性较强,结果的准确度较低；流体包裹体法不必考虑复杂的地质历史和压力形成机制,但目前在绝多数情况下获得的是均一压力或最小捕获压力.进一步研究盐水包裹体的等容线,可提高古流体压力的准确度.每种恢复方法都有其优缺点,对其局限性进行了重点讨论,并指出了发展方向.%In order to optimize the technical methods of paleo-fluid pressure build-up, the methods for paleo-fluid build-up in basins are sorted out, compared, analyzed and discussed based on the research progresses at home and abroad. The build-up methods mainly include mudstone acoustic travel time method, basin modeling method and fluid inclusion method. Mudstone acoustic travel time method is cheap and rapid. However, it can only recover the paleo-fluid pressure at the maximum burial depth, and it is not suitable for other abnormal pressure formation mechanism except for uncompaction. Basin modeling method can recover the evolutionary history. But in this method, its geological model is complex and has many parameters, moreover many of which have relatively high uncertainty, therefore the accuracy of result obtained by this method is relatively low. Fluid inclusion method can get paleo-fluid pressure without considering the complex geologic history and pressure formation mechanism. However, in most cases ,this method can only obtain homogeneous pressure or minimum trapping pressure at present. The further study on isometric line of saline inclusions can increase accuracy of paleo-fluid pressure. Each recovery method has its own advantages and disadvantages, but the limitation has been discussed, and moreover the developing method is pointed out.
