基于国内外相关文献的调研和剖析，综合前人的研究成果，总结了琼东南盆地超压的分布特点及深水区压力预测等方面的研究进展。结合现有的钻井、实测压力、地质、地球物理及地球化学等资料，分析了琼东南盆地的超压成因及其形成机制。分析表明：新构造期(5.3Ma)以来，琼东南盆地表现为快速的沉积沉降，特别是西部晚期的巨幅沉降，沉积地层很厚，且泥岩发育，这种独特的快速沉积沉降是该盆地超压形成的重要地质条件。低渗透性沉积层在快速沉积沉降过程中受到上覆岩层欠压实作用而产生超压，其实质是孔隙流体供与排不平衡，是该盆地超压形成的主要机制。同时，水热增压及新生流体等的辅助作用，会使压力进一步升高，使超压进一步加剧。研究成果对琼东南盆地的勘探与开发具有理论指导和现实意义。

It is a typical sedimentary basin of both high temperature and overpressure in the Qiongdongnan basin.Based on collecting the literatures from foreign or our country as well as previous research achievements related to overpressure, we conclude the research progress of pressure prediction in the continental slope area, and the distribution characteristics of overpressure in the basin.In combination with logging data, test pressure data, and geological background, physical geography and geochemistry, we discuss the overpressure genesis and its main formation mechanism in the basin.It is an important geological condition for overpressure formation to be rapid subsidence and high sedimentation rate, especially higher sedimentation rate in the western area than other area of the basin which results in the thick sediments with a certain thickness of mudstone since the Neotectonic event (5.3Ma).Overpressure formation in the basin is mainly resulted from rapid subsidence of low permeability sediments and disequilibrium compaction of overlying strata.Thus, it is essential for the overpressure formation to be imbalance between supply and discharge of pore fluid in the Qiongdongnan basin.Meanwhile, the overpressure is exacerbated further by gas generation and thermal expansion of fluid.So, it is significant in theoretical and practical aspects to oil and gas exploration and development in the Qiongdongnan basin.
