Petroleum exploration practices and tackling key technical problems have improved the development of reservioring theories in marine carbonates in Tarim basin and that in foreland basin.As for reservoiring theory in marine carbonates

the new understandings include the followings: palaeohighs and their slope zones adjacent to the major source rocks are the favorable locations or zones for hydrocarbon enrichment;faults and unconformities are the major pathways for hydrocarbon migration and accumulation and the favorable reservoiring condition;good reservoirs composed of multi-cycle karsts and structural fissures are the crux of hydrocarbon enrichment as well as high and stable productions;good seals

multistage reservoiring and later adjustment are important factors for preservation of oil/gas reservoirs and the formation of complex oil and gas accumulations.As for reservoiring theory in foreland basin

the new advancements are as follows: faults passing through source rocks would play an important role in linking source rocks with reservoirs;the widely developed structural traps

good seal and late tectonic activities would have important control on reservoiring.The development and perfection of reservoiring theories have provided distinct guidance to exploration in Tarim basin: Akkule uplift

Yakela faulted uplift

Tazhong palaeohigh

Hetianhe palaeohigh

Guchengxu palaeohigh and the southern edge of Kuqa depression are the favorable areas for exploring large and medium oil/gas fields;while the southern part of Bachu uplift

Kongquehe slope and deep strata in the craton basin are the important domains that are worth to study and to explore.
