The Lunnan low uplift of the Tabei Uplift is a hotspot for oil and gas exploration in the Tarim Basin, in which a series of fractured-vuggy oil and gas reservoirs controlled by faults are found. At present, the faults in the study area are mostly studied in a certain block, which needs to be systematically hackled in the whole study area. Based on a large number of three-dimensional seismic data, the method of fault structure analysis is adopted to analyze the types, structural features, and formation and evolution processes of faults in the study area. The results show that: There are three types of faults, such as reverse faults, strike-slip faults, and transtensional faults. The reverse faults are distributed in the northwest of the study area and central Lunnan areas. There are both detachment thrust faults and basement-involved thrust faults. Strike-slip fault is the main fault type in the study area. Three kinds of structural styles are developed on the profile, which are high-steep style, positive flower, and semi-flower. Four kinds of structural styles are developed on the plane, which are linear extension, chess board format, braided structure, and horsetail structure. The strike-slip fault has obvious segmentation along the strike. The transtensional faults are mainly small, which are distributed in the Mesozoic and Cenozoic. The transtensional faults are stepped, grabbed or negative flower on the profile. On the surface, most of them are arranged in the form of en echelon along the strike-slip faults or the reverse faults. Three methods are used to reveal the evolutionary history of strikeslip faults, reverse faults, and transtensional faults respectively, which are the differences of upper and lower fault structure styles, the age of strata deformed by faults and growth index. The faults have undergone 4 stages, which are the middle Caledonian, the early Hercynian, the late Hercynian-Indochina, and the Yanshan-early Himalayan. The fault evolution has certain inheritance.
