The Study On Stabilizing Oil Production And Controlling Water Of Chang2Member In Pantong Oilfield Xiaping Area, The Ordos Basin

This paper analysis the characteirstics of structure, sedimentary facies, sandstone bodydistirbution, fluid properties and heterogeneity of Chang2Member in Panglong Oilifeld in theOrdos Basin, Put forward the method of stabilizing oil production and controlling water inPanlong Oilifeld. On the basis of comprehensive geologic study, the research carired out onthe oil-water distirbution and accumulation in Chang2Member. As the oil production declinesharply duirng the ifrst year of production, conduct injection the water. Through the analysisof dynamic water injection, water injection development effect, well pattern adaptability,found the factors inlfuence the residual oil distribution in Chang2Member. Finally togetherwith the present situation of development in the study area and water cut of stabilizing oilwater control countermeasure is put forward. The study has a guiding signiifcance forprolongation the water breakthrough time and slowing down the water cut of fast growth,lengthens the oil well productive time, improve the situation of oil well in the Ordos Basin.
