Fine Reservoir Description Of Chang 6 Oil Formation In The Bai 153 Block,Huaqing Oil Field

HuaQing oilfield is low permeability reservoir development main battlefield,long 6 major reservoir has the oil-bearing area,reservoir thickness,low permeability,strong reservoir heterogeneity,the characteristics of water drive with low degree(45.2%),oil well productivity,decreasing(early month decline 30%),the single well production capacity of only 1.6 t/d.In order to improve the development effect,should be in the early development of reservoir fine description,characterization of reservoir geology,research and development technical policies,timely adjust the opinions,provided a basis for the next step development adjustment.Built in this research area is among the first large-scale ready blocks,carry out white 153 blocks chang 6 oil reservoir fine description of research development has the very good reference for other blocks.This article in view of the chang 6 oil distribution characteristics of large area,carried out a subdivision single sand layer,characterization of connectivity,the depiction of reservoir flow unit,the development present situation analysis research,through the prediction of technology development and making,put forward the technical countermeasures for sustainable development in the regions.Finally resolved the contradictions in the process of the development,and put forward the reasonable and effective development measures and more effective governance and old reservoir adjustment scheme of a more scientific,to guide developed oil fields on the yield of a more reliable basis.
