Study Shen95 Block On Distribution Of Remaining Oil And Reservoir Heterogeneity

Shen95 block lies in the Northern part of Jing an bao structure belt of Da min tun sag. This reservoir has many features such as low porosity,low permeability and high condensation .The content of clay mineral is high (up to 10.1%). Reservoir heterogeneity is serious, so it is difficult for water injection .In view of the problems in the block fault , we should begin with the basic documents , clarify the geologic and reservoir characteristic of the block ,and find out a suitable approach for 95 block development . In this way We can improve the development effect and economic benefit .Through the research of this paper , we can have a clear knowledge of the formation,reservoir,structure,sedimentary facies and distribution of remaining oil in this block. ,and we can also get a large amount of dynamic and static outcomes .It has a directive effect in reservoir restruction , injection-production regulation and the high speed test in well spacing crowdingFor quite a long time, there is no integral Method in studying high pour-point oil reservoir and remaining oil distribution. This paper present reservoir characteristic and the lows of remaining oil distribution, which established the framework of reservoir formation and studied the reservoir heterogeneity based on advanced sequence stratigraphy. On the other hand, the lows of remaining oil distribution is studied based on the geostatistics , computer and microfracture development , which will provide the theory foundation for the adjustment of oilfield development and the implementation of horizontal sidetrack and a significant method for high pour-point oil reservoir and remaining oil distribution.
