摘要: 在我国西部前陆盆地山前构造带,地应力对储层性质的影响很大,不同的局部应力环境造就了显著的储层品质差异.研究发现,泥岩对地应力响应十分灵敏,利用这种特性可对地应力进行定性、定量评价.将计算结果与声波发射试验确定的原地应力大小进行对比,两者在误差范围内吻合较好,这表明该方法具有一定的可靠性.在对单井地应力分析的基础上,确定了地应力分布与储层分布的关系,研究了地应力对储层品质的影响,并分析了局部地应力分布与构造样式的关系,为复杂地质条件下油气储层评价提供了新思路和新方法.

Abstract: The terrestial stress has a great influence on reservoir quality of the piedmont tectonic belts of foreland basin in the west China. The characteristics of shale,in particular,shale resistance can easily reflect the state of terrestrial stress.This characteristic can be used to evaluate the terrestrial stress qualitatively and quantitatively.The preciseness of the method was proved by comparison of the calculated stress with the results obtained from Acoustic Emission experiment.Based on the terrestrial stress analysis on a single well,the relationship between terrestrial stress distribution and reservoir distribution was determined.The effect of terrestrial stress on reservoir quality and the relation of local terrestrial stress with structural styles were investigated.The research results show that the high-quality reservoir always coincides with the relatively low terrestrial stress zones.

Key words: piedmont tectonic belt, terrestrial stress, acoustic logging, reservoir, oil and gas distribution, quantitative evaluation
