Title: Reservoir Forming Patterns and Exploration Analysis of New Area and New Field in Tarim Basin
Abstract: Because of the multicycle,unbalance of tectonic movement and sedimentary evolution,the reservoir forming and distribution is very complicate.In the past few years,with the growing knowledge of Tarim basin,it is necessary to strengthen the study of reservoir forming regularity.On the basis of proved reservoir forming characteristic,the reservoir forming pattern can be divided into seven types,including anticline gas reservoir from foreland subsalt compaction,structure-lithologic irreducible reservoir in foreland upsalt,structure-lithologic reservoir in foreland platform-basin folding area,carbonate weathered crust in platform-basin palaeohigh,interstratal karst stereoscopic combined reservoir in carbonate weathered crust,clastic combined reservoir in platform-basin palaeohigh,structure-lithologic reservoir inplatform-basin long-term palaeoslope reverse,structure-lithologic irreducible reservoir in platform-basin long term bulge deep layer.Through analysis of the reservoir forming pattern and distribution regularity in different structure area and structure layer,the paper point outs that Kuche depression,Tabei uplift and Tazhong uplift are the three main fields for increasing reserves and production.In addition,Taxinan depression,west Qiulitage,Silurian to Triassic Formation in the platform-basin area of Tarim basin and low bulge in the east of Tarim basin are the important target for further exploration.
