Abstract: The current petroleum exploration activities in the Tarim Basin are mainly concentrated in the Mangar and Kuqa petroleum systems.Exploration practice proved that multidisciplinary study using seismic (seismic-structural interpretation, constraint seismic inversion,coherence calculation),logging reservoir evaluation,digital simulation on fracture distribution,production test and integrated geological analysis enables to identify the features of the carbonate reservoirs,facilitates to do lateral reservoir prediction and realize the oil and gas distribution laws and is a very useful method to do exploration in the carbonate oil and gas provinces.As for the complex high and steep structural belts,salt distribution areas,high geostress and mountainous surface in the Kuqa system,using the balanced cross section technique,fault-related fold theory and advanced seismic acquisition,processing,imaging and interpretation,as well as rapidly penetrating the huge salt interval drilling technique facilitates detailed and effective structural interpretation and oil & gas identification and may lead to significant exploration breakthrough.
