摘要
To clarify the development orientation and potential target in the similar fields,taking A oilfield located at the northern end of the central structural ridge of Yellow River Mouth Sag as an example,genesis of Neogene multiple oil & water system fault-block reservoirs is systematically researched.The effective matching of sand reservoir and fault connecting source rocks is a key factor that controls hydrocarbon accumulation.The reservoir distribution of A oilfield is studied on the basis of fine stratigraphic classification and reservoir characterization by the integration of well logs and seismic data.Reservoir characterization combined with the analysis of source-connected faults,the controlling effect of reservoir-fault coupling on oil and gas distribution is systematically studied.Firstly,the vertical distribution of hydrocarbon accumulation may be controlled by a "coupling" between the differences of vertical fault activity and relevant sand reservoir distribution.Secondly,the horizontal distribution of hydrocarbon may be controlled by the "coupling" between the differences in horizontal fault activity and the abundance of sand reservoir.Finally,the contact patterns of sand reservoir and fault affect the oil and gas accumulation.
