摘要
To identify the influence of base level cycle on the differences of the reservoir quality among the fluvial reservoir at different stages of base level cycle,the main controlling factors of fluvial reservoir quality in Es 72 Formation of 2block in Shengtuo Oilfield were analyzed based on the sediment dynamic analysis of high resolution stratigraphic sequence and quantitative analysis of core testing and statistical data.The control mechanism of base level cycle on the differences of the reservoir quality among the fluvial reservoir at different stages of base level cycle is identified.The pattern of the reservoir quality among the fluvial reservoir at different stages of base level cycle is confirmed.The results show that the diversity of sedimentary environment of reservoir at different stage of base level cycle was caused by the variation of accommodate space and sediment supply due to the changes of the base level in different scale.On that basis,the baselevel cyclic influenced facies controlling porosity-permeability log interpretation model is established.The porosity-permeability logging interpretation precision is improved for the target layer in study area.
