Directed by new theories and approaches of sedimentology, diagenesis and reservoir evaluation, focused on marine clastic reservoir of donghe sandstone member, in tarim basin, strata and depositional system of donghe sandstone member are classified ; typical depositional facies types, depositional model and horizontal distribution have been studied through depositional facies analysis of 17 single wells, combined with seismic data. major diagenetic events, stages and " four history " collaboration have been systematically analysesed, furthermore, the relation between reservoir diagenesis and porosity evolution has been built ; thorough studies on reservoir lithology, physical property and pore structure, reservoir development related to depositional envoironment, diagenesis and tectonic has been discussed ; reservoir has been evaluated and predicted by five influential parameters drawn from the results of the study on depositional facies, diagenesis and reservoir characteristic. in the end, favourable reservoir body distribution has been pointed out
