阐述了构造应力场在盆地演化分析、油气的生成和运聚、裂缝形成等方面的应用现状及发展趋向,指出在盆地演化分析中构造应力场的研究应以盆地形成演化过程中的原始沉积特征为依据,构造应力与流体(油、气、水)之间的相互作用表现为应力场、温度场、渗流场的相互耦合,定量研究它们的耦合关系及时空变化规律是认识构造应力和流体作用的主要途径。比较客观地探讨了构造应力场模拟、构造应力大小和方向、起源等问题。
The application status and development trend of tectonic stress field in basin evolution analysis, hydrocarbon generation and migration, formation of fractures and so on are described. It is pointed out that the study of tectonic stress field in basin evolution analysis should be based on the original sedimentary characteristics , The interaction between tectonic stress and fluid (oil, gas and water) is manifested as the coupling of stress field, temperature field and seepage field. Quantitatively studying their coupling relationship and temporal-spatial variation is to recognize the tectonic stress and fluid effect The main way. More objectively discussed the tectonic stress field simulation, tectonic stress size and direction, origin and other issues.
