Abstract:

The textural maturity and compositional maturity of Fute conglomerate oil reservoirs are low,the cements are mainly tuffaceous materials with double modular texture.Reservoir physical property is affected by fractures.The fractures,however,made little contribution to porosity,but considerable contribution to permeability.According to the types,the contents of cements,and facture development,the reservoirs could be divided into fracture,pore fracture and pore cave types.It is suggested that the above mentioned reservoirs of Ha-22 fault block developed well than those of Ha-43 fault block.On this basis,reasonal ratio of injection to recovery and presure,the injection and recovery stratigraphic horizons are determined and the results are satisfactory.

Key words: conglomerate oil pool, reservoir property, types of fracture, pore assemblage, application
