FMS成像测井是较为先进的测井技术，由于其具有高分辨率、直观性等特点，在原始产状恢复、沉积相态研究中有广泛的应用。位于西北太平洋的Shatsky(沙茨基)海隆是综合大洋钻探计划324航次的重点研究区域，通过对该航次U1347A、U1348 A、U1349 A 3口钻井中的FMS成像测井资料的处理及相应地质构造的解释、产状恢复，进行了构造应力场的探讨。得出结论是，Shatsky海隆TAMU地块的形成比较符合大洋中脊扩张学说，而对Ori地块的应力场分析则显示Ori地块的形成较符合地幔柱头假说。

Formation Microscanner Service (FMS) is an advanced logging technology. Because of its advantages of high resolution and intuition, FMS measurement has been used in the recovery of original dip direction of structural elements, and that of sedimentary beddings. The Shatsky Rise is a key study area during the IODP Expedition 324. After FMS processing for Holes U1347A, Hole U1348A and Hole U1349A, interpretations of geological structures and their dip directions are discussed in this paper. We conclude that the formation of the TAMU Massif is consistent with the seafloor spreading theory while the formation of the Ori Massif has no obvious preferred stress field, being deduced to be related to a mantle plume head. 
