The Description Of Chang6Segment Reservoir In Huai Shuang Zhuang Exploration Area Of Yan Chang Oil Field

Late Triassic,in the influence of Indosinian orogeny,Ordos basin descent fastly.Exploration demonstrates that Huai Shu Zhuang area,which locates in the hinterland of ordos basin,not only has full of bathile hydrocarbon native rock in the Chang7zone,but also develops sandstone in the Chang6zone and oil saturation is favorable.But,becaise of rolling explortation and development, lacking system research of depositional environment,sedimentary facies and micro facies,indistinct awareness of reservoir character and mechanism in the early stage,they affect exploration object and development scheme directly.This article,using sedimentologybasin analysis,petroleum geologygeostatistics et al. advance theorys as guide,in the base of synthetical analyse of dynamic and static state oil geology data of research area.Integrated using microfacies recognition teclulology,reservoir evaluation technologyreservoir description and3D static face control geology model building technology,via analysing sequence stratigraphy,wavelet transform establish equitime framework, classify microfacies type,research reservoir microscopic feature,confirm’four propertys’mode,anisotropic quantification evaluate reservoir,at last,building configuration of ground model:stratal surface model；sedimentary facies model；layer properties model,we make a exact,detailed, accurate reservoir description.raising reservoir description accuracy.The profitaolity range,which we forecast,offers a strongly basic for oil development.
