C Iii Oil Group Of Four Oilfields In The Tarim Basin, Reservoir Description,

The thesis makes an extensive study about the reservoir description and stochastic oil modeling and dynamic production analysis .taking TZ4 oil field CM oil reservoir as an esample.To solving the relative problems of reservoir :the rise of the water content ratio of reservoir.especially the quicken coning speed of horizontal well .We describe the TZ4 reservoir on the base of old study over again.It content the conformation .fault , the character of sediment .matter properties.the restain of the layer distrbuting of the reservoir.We stabling conformation model .geological model of the reservoir and prediction model.with the quantificational data study numerical simulation .On the base of this ,we simulate ang choice the best development project of the reservoir,restrain the bottom water coning rate,keep the state and high oil output.Under the guidance of modern sedimentology ,by means of the theory and method of high defintion stratigraphic geology.we establishes the primary model under the horizontal of high density wells.analyses the elements and mechaism of affecting the residual oil distributing in sandstone reservoir according to the geologic orgin and development condition.Secondly.on the basis of establishing reservoir model.the thesis choose the method of the combination of seismic inversion and stochastic modeling,which is a valid method for rebuilding the reservoir model.establishes the huge model of modeling,this thesie buildes reservoir parameter model by use of the upscding ,and through the study of reservoir simulation.the thesis describes the residual oil different development regulating plans,which provides scientific ground for flood pattern modification and flood development regulation.At the same time, this thesis stress study the layer of the mrrine deposit sand resivoir for the interlayer is the key factor which aroose the reservoir heterogeneity.Thesie build the interlayer model to grasp the key cause which arose the bottom water coning .We simulate the bottom water coning of individual well .pressure .water injection and so on .On the base of the simulation ,we choice the best production project.
