从地质特征入手，探讨本区北东向反向正断层的形成机制及与油气聚集的关系，指出下一步的勘探方向。研究认为，北东向反向正断层的形成受北西—南东向张应力及右旋剪切力作用控制，反向正断层的走向与张应力方向基本垂直；反向正断层封堵性能的好坏与断面力学性质有关，相对挤压区有利于油气聚集，油气主要分布在主干断层的弧弯部位内侧；下一步的勘探方向应放在向海南洼陷过渡的斜坡部位，在寻找构造油气藏的同时注意寻找沙河街组岩性油气藏。
Beginning with the geological features, we discuss the formation mechanism of the NE-RE and the relationship with the hydrocarbon accumulation in this area, and point out the exploration direction in the next step. The study suggests that the formation of the NEW is controlled by the NW-SW tensile stress and the dextral shear force, and the direction of the FWHM is almost perpendicular to the direction of the tensile stress. The sealing performance of the reverse normal fault Good or bad is related to the mechanical properties of the section. The relative crushing zone is favorable for the accumulation of oil and gas, and the hydrocarbons are mainly distributed inside the arc bend of the main fault. The exploration direction in the next step should be placed on the slopes that transition to the Hainan depression. At the same time, pay attention to find the Shahejie Formation lithologic reservoirs.
