Mu34 Reservoir Oil-water Distribution Regulation And Formation Energy Evaluation

Mu34 Y10 reservoir is located in the southwest part of Shanbei slope,Ordos basin.The reservoir is a shallow-buried edge-bottom water reservoir and is controlled by structure and lithology.The reservoir had been developed using the natural energy in the beginning of development,and water injection well was deployed in the south region of the reservoir after two years of development.Some problems gradually appear such as active edge-bottom water and fast increase of water cut.There is no clear understanding of the water-oil distribution and reservoir energy.To solve these problems,this thesis firstly analyses the geological characters,including formation,structure,sediment and reservoir.Secondly,the thesis analyses the oil-water distribution of horizontal direction and vertical direction.The effect of structure on oil-water distribution is evaluated.Thirdly,the reservoir energy is analysed from the four paraments,water-oil volume ratio,reservoir pressure,water invasion volume and edge-bottom energy.The thesis acquires the clear understanding of the oil-water distribution and reservoir energy,therefore providing a reference for the later development of similar reservoir.
