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、U1348A、U1349A3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。
FMS imaging logging is a relatively advanced logging technology. Due to its high resolution and intuitiveness, FMS imaging logging is widely used in the study of the recovery of original occurrences and sedimentary facies. The Shatsky seamounts located in the northwestern Pacific Ocean are the key research areas of the integrated ocean drilling program 324 voyage. Through the processing of the FMS imaging well logging data and the interpretation of the corresponding geological structures in the wells U1347A, U1348A and U1349A3, Reproduction, the tectonic stress field was discussed. It is concluded that the formation of TAMU massif in Shatsky seamounts is more in line with the theory of mid-ocean ridge expansion, whereas the stress field analysis of Ori block shows that the formation of Ori massif is more consistent with the mantle-plume hypothesis.
