摘要： 根据实测地应力资料,采用二维有限元回归分析方法,结合有限变形理论和多元线性回归理论,可得到计算区域内的构造应力场。对某油田区块的构造应力场回归分析表明,计算结果与实测值吻合较好,研究结果与构造地质、石油地质分析结论相一致,对油气勘探开发具有指导意义。

Abstract: Based on measured stress data, integrating 2D finite element regression with fast lagrangian analysis of continua and multivariate regression, the tectonic tress field of studied area can be calculated. Taking a field block as an example, its tectonic stress regression analysis shows that the calculated results are in good agreement with the measured data and the conclusions from analyses of tectonic geology and petroleum geology. This method can be as reference to petroleum exploration and development.

Key words: tectonic stress field, regression analysis, reverse analysis, numerical simulation
