| With the development of oil,research of remaining oil distribution is already a key question which is eagerly solved in the academic community.Xinmu oilfield is located in the nosing structure of Fuxin uplift in southern Songliao basin.The bed of interest of Xinmu oilfield is Fuyu reservoir of Quan ? and Yangdachengzi oil reservoirs of Quan III.Yangdachengzi oil reservoirs is meandering channel sedimentary.It belongs to low-permeability fault-lithostratigraphic reservoirs.Mu101 well field lack basic data.And some wells has drilled Yangdachengzi oil reservoirs.Moreover,it's meandering channel sedimentary so that the distribution of sand body and oil-water is unclear and complex.Residual oil is more dispersive.There is a great deal of methods to research the distribution of residual oil.So far,the study of single well long water-flooded layer and giving priority to development geology and the prediction of giving to numerical simulation are the primary methods.This paper begins from basic geology.And it makes full use of 3D seismic data,well log data,single well drilling data,static state and dynamic state data.More tasks about establishing 3D geological model are done.In the basis of the study about distribution pattern of residual oil,combining the data of static state and dynamic state with the result of injection and production,analyze the distribution of residual oil on plane and vertical.And then predict the residual oil distribution of single well and important layers.This paper summarizes the distribution pattern of H block of Mu101 well field and it includes five types:the neighbouring area of oil sources of region,the better sand body of channel;the lower block of antithetic fault;the high sand body which connects with faults,the sand body which is not controlled by the well network.And this paper predicts the remaining oil distribution of H block.Finally achieve the goal of improving developing effect and increasing available reserves. |
