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.
