Abstract: Through analyzing a large number of overseas exploration cases in the past 30 years of CNPC“going out”,the current exploration status,distribution characteristics and exploration models of lithostratigraphic reservoirs were systematically summarized,and the exploration potential of global lithostratigraphic reservoirs and outlook for lithostratigraphic reservoirs of CNPC overseas were pointed out. The results show that:（1）The exploration of global lithostratigraphic reservoirs has gone through four stages,and is currently in a mature stage of development. The large-scale deep-water sediments and reefs have become the main areas for discovering giant lithostratigraphic oil and gas fields.（2）Lithostratigraphic reservoirs newly discovered by CNPC overseas exploration and global lithostratigraphic reservoirs are mainly distributed in composite traps,mainly developed in foreland,rift and passive continental margin basins,The former has the largest reserves found in rift basins,followed by foreland basin,while the latter has the largest reserves in foreland basin,rift basins was the second.（3）CNPC overseas has implemented the same deployment and integrated exploration strategy for structural and lithostratigraphic oil and gas reservoirs,forming three distinctive exploration models:Stereoscopic exploration for multiple lithostratigraphic reservoirs,discovered high abundance lithologic reservoirs in lower combination,high buried hill reservoirs and low buried hill-lithologic complex reservoirs in Bongor Basin of Chad,and channel,fan delta,subaqueous fan and buried hill reservoirs in South Turgai Basin of Kazakhstan;High resolution 3D seismic exploration for complex lithologic bodies,discovered large gentle slope reef-beach complex gas reservoirs in Amu Darya Basin of Turkmenistan,giant lacustrine reef-beach oil fields in Santos Basin of Brazil,and deep-water turbidite sandstone biogas reservoirs in Rakhine sub-basin of Myanmar;Geology and engineering integration exploration for thin layer low amplitude structural-lithologic complex,discovered low amplitude structural-lithologic complex oil reservoirs in Oriente Basin of South America and thin layer reef-beach oil reservoirs in the Oman sub-basin of Middle East.（4）The exploration of global lithostratigraphic reservoirs will expand from mature exploration areas to frontier areas with low exploration levels,and from onshore to deep-water and ultra deep-water areas. The deep-water sedimentary bodies,subaqueous fans,and reefs in passive continental margin basins will be the hotspots of lithostratigraphic reservoir exploration. Subaqueous fans and burial hills in rift basins,composite traps related to reefs in foreland and passive continental margin basins will be the main targets of lithostratigraphic reservoirs exploration for CNPC overseas,which have favorable prospects for exploration.

Key words: lithostratigraphic reservoirs, low buried hill-lithologic complex, deep-water sediments, reef-beach complex, low amplitude structural-lithologic complex, exploration model, 3D seismic exploration, rift basin, foreland basin, CNPC overseas exploration
