摘　　要：地层倾角测井资料的解释目前尚无完善的理论指导。通过应用倾角散射程度与沉积环境的关系,对B凹陷沉积特征和物源方向进行了分析,得出B凹陷是受2条主河道控制的扇三角洲前缘辫状河道沉积;通过双井径扩径方位并结合密度、纵波和横波等测井资料剔除非构造应力引起的井壁崩落层段,对A凹陷腾一段最大水平主应力方位进行了统计分析,得出不同的构造部位沉积环境不同,地层最大水平主应力方位也存在差异;列举了断层解释模式以及高陡构造处理参数选取的重要性。No perfect theories can be applied to the explanation of diplog at present. According to the relationship between dip scattering strength and depositional environment, the deposition characteristic and the sand source direction of depression B were analyzed. The depression B is the deposition of a fan delta with braided river course which is controlled by two main rivers. The distribution of the maximum horizontal stress for the Teng 1 member of depression A was analyzed. It was found there exist different parts of the structure corresponding to the different depositional environment, and also the different distribution of the maximum horizontal stress. The information of double caliper enlarged direction, combined with the density, the vertical wave and the transverse wave, is used to e-liminate the influence of layer segments in collapsing borehole. Some samples are used to verify the importance of selecting parameters in high-steep structures and the explanation models of fault.
