Carbonate reservoirs can be divided into intra-sequence reservoirs and sequence boundary reservoirs based on study of sequence stratigraphy.First of all

the development potentials of the two types of reservoirs mentioned above are defined according to the growth rate of carbonates

then the distribution of intra-sequence reservoirs is predicted through detailed delineation of the distribution of isochronous unit reef flat facies;and the development of sequence boundary reservoirs is predicted on the basis of analysis of the types and natures of sequence unconformity surfaces.The Devonian in Shiwandashan area is a "progradational wedge" platform with low growth rate of carbonates

and is dominated by reservoirs controlled by "type-Ⅰsequence unconformity interface";as a whole

the reservoirs are well developed.The Carboniferous is an "aggradational" platform in epicontinental sea with low growth rate of carbonates

and is dominated by sequence boundary reservoirs under the control of the fourth-order and third-order sequence boundaries;the reservoirs are poorly developed.Both the intra-sequence reservoirs and the sequence boundary reservoirs under the control of third-order sequence boundary in the Lower Permian are poorly developed;only the scattered point reef reservoirs developed to the north of Pingxiang-Dongmen fault and the karstic

fractured and vuggy reservoirs controlled by the sequence boundary formed during Dongwu tectonic movement are worthy to be considered.Neither the intra-sequence re-(servoirs) nor the sequence boundary reservoirs are developed in the Upper Permian carbonates.As for the Lower Triassic

both intra-sequence reservoirs and sequence boundary reservoirs are developed in the northern part of the platform due to the high growth rate of carbonates

but neither of them is developed in the southern part of the platform due to the low growth rate of carbonates.The main reservoirs are closely related with the regression phase of second-order eustatic cycle.
