摘要:

      随着国内外越来越多低压油气藏的发现,沉积盆地中低压形成机制及其与油气成藏的关系日益受到重视。通过对国内外相关文献的调研,系统总结了低压成因方面的研究现状、存在问题及发展趋势。将低压成因归纳为4个方面:①岩石孔隙空间增大;②孔隙流体体积减小;③流体承压高度降低;④原始压力的保存。同时指出,低压形成的根本原因就是孔隙流体的供排不平衡。针对低压油气藏形成各种控制因素的定量模拟和评价以及低压油气藏的压力演化等方面的研究将是今后的主要方向。

Abstract:

       With the discovery of more and more low-pressure reserviors at home and abroad, the mechanisms of low pressure and its relation to oilgas reservoir forming in sedimentary basin have been drawing increasingly attention. Through investigating the corresponding references, this paper systematically analyzes the present research situation, problems and development trend of the origin of subnormal pressure. The origin of subnormal pressure can be concluded mainly into four aspects: (1) pore space increase; (2) pore fluid volume decrease; (3) piezometric surface decline; (4) original pressure preservation. It also indicated the basic reason of low pressure formation is the unbalance of supplying and discharging of pore fluid. The studies of formation mechanism of low pressure and its relation to oil-gas reservoir forming have made progress. The quantitative simulation and evaluation of controlling factors of low pressure and the pressure evolution of low pressure reservoir are the major research subjects in future.

 

Key words: Low pressure reservoir    Formation mechanism    Present research situation    Development trend.
