摘要

通过构建挤压构造背景应力背景下静态盐构造模型,模拟计算盐盆地周围的应力变化,分析不同几何形状的盐体所导致的应力扰动,同时测试盐体起伏大小对应力扰动的影响。使用有限元方法设计了3个突起洼陷相互组合的双层盐模型,并计算其周围的应力扰动,结果表明盐体几何形状与其周围沉积物中的应力扰动有很大关系,且其突起和洼陷的起伏程度（平缓或陡峭）也会影响应力扰动的大小。挤压构造应力环境下,突起盐体附近产生挤压的水平应力、平面上的法向应力和垂向应力;相反地,洼陷盐体附近产生拉张的水平应力、法向应力和垂向应力扰动。此外,突起的起伏越平缓,所产生的应力扰动越小;洼陷的起伏程度越陡峭,沉积层中的应力扰动会减小越多。以库车坳陷克拉苏西剖面盐构造为例进行了应力模拟实验,证明上述结论适用于该盐构造模型。本研究成果为盐盆地系统盐体周围应力扰动预测提供了依据。图13表1参46

Abstract

By building a static salt structure model under compression stress background, the stress changes around salt basin were simulated to find out the stress perturbations caused by different shapes of salt bodies and test the effect of amplitude of salt body on stress perturbation. A two-layer salt model with 3 bulges and sags was designed with finite element method to calculate the stress perturbation around the salt. The results show that the shape of the salt is closely related to the stress perturbation in the sediments around the salt, and the fluctuations of the bulge and sag (smooth or steep) can also affect the magnitude of the stress perturbation. Extrusion horizontal stress, normal stress and vertical stress on the plane would occur near the salt uplift under compressive tectonic stress environment. In contrast, tensile horizontal stress, normal stress and vertical stress would occur near the salt subsag. In addition, the smoother the bulge, the smaller the stress perturbation produced will be; the steeper the subsag, the more reduction of stress perturbation in the sediment will be. The stress of salt structure in the western of Kelasu of Kuqa depression was simulated, which proves that the previous conclusions are applicable to this salt structure. These conclusions provide scientific basis for the prediction of stress disturbance around the salt basin system.

Key words： numerical simulation; salt structure; stress perturbation; Kuqa depression; oil drilling
