Fine Reservoir Description To Block 1 Jiushang Reservoir In Naiman Oilfield

In China,one of the important oil and gas reservoir formation types of Cenozoic continental basin,oilfield in order to speed up the oil and gas exploration in liaohe nai man,further do well the construction of a productivity,the need for fine reservoir description and residual oil distribution study.In this paper,the geological,seismic,logging,reservoir engineering and numerical simulation,unification on the basis of reservoir fine description,combining static and dynamic data of new reservoir,and determine the division standard of reservoir,and the stratigraphic correlation and classification to the single layer.Study of reservoir structure form,describe the micro structures of enrichment of remaining oil traps and the relationship between the micro structures and residual oil.Developing unit,small bed micro structure study,establish fractal reservoir group,sandstone of macroscopic structure model and the micro structure model of developing unit.Application data to sedimentary microfacies study,focuses on the influence of different micro relative development.Diagenesis,reservoir property and heterogeneity,after water injection characteristics research;To carry out the logging reservoir evaluation,reservoir geological model is established.Based on the changes in the nature of the fluid in the development process,such as research,reservoir fluid model is set up,stratification plane distribution of different fluid.Finally,in the depositional model,structure model,reservoir fluid model and reservoir geological model,on the basis of establishing nine on reservoir comprehensive three-dimensional geological model,reservoir geological comprehensive evaluation.Double calculation on nine section of the reservoir reserves.The regularity of enrichment of remaining oil distribution study.
