Research About Reservoir Description Of Xianhezhuang Oil-field He31 Faults

Research of distributing laws of the remaining oil is key to improve the final producing rate of complex fauIted~bIock oil and gas fields0 At present, reservoir numerical modeling is one of the best methods to quantitatively describe the distribution of the remaining oil , which is based on the correct contribution of reservoir geological model , Basic way to solve this question is to make fine reservoir description that includes acute describing of reservoir characteristics such as structure, reservoir, fluid and development H31 faulted-block area of central anticlinal belts in Dongying sag, which now wholly gone into more than twenty years development, is a typical complete fauIted-bIock oil and gas fieldo In the process of researching, besides basic geological analysis, we mainly analysis as folow: Fine description of structure shape by 3D seismic graph -technology; Careful division of sedimentary little facies comprehensive by analysis of seismic fades, single well facies and logging data, On the base of above ,with consideration of developing movement situation ,. and place a good geological basis for the stable production with control of eater and in crease of oil field.
