Abstract: This paper outlined the exploratory achievements in central Tarim area, discussed its resource potentials in north slope structural belt and central fault horst zone,analyzed five causes for failure of drilling, in which the major cause is indeterminate structures for drilling resulted from static corrections and average velocity field problems. It is pointed out that the exploration of central Tarim area should focus on No.1 fault belt in lower structural layer and that of low amplitude in middle structural layer. In addition, evaluation in trap types of low amplitude anticlinal trap in Donghe sandlayer of Carbonifeous and stratigraphic-lithologic trap of Ordovician should be paid attention to,improving ability of prediction of effective carbonate reservoir; in light of effect of igneous rock on hydrocarbon reservoir and developed characteristics of Ordovician “domal abnormal body” search for new domains for petroleum exploration.
