摘要
现代精细油藏描述是提高油气采收率的重要技术手段,主要应用三维地震、钻井取心、测井、开发等综合资料进行地层划分与对比、储层物性、油气水分布、沉积微相研究和石油地质储量计算。随着采出程度的提高,需要进一步描述井间储层展布和非均质的变化,这就需要井间地震技术来满足开发要求。樊124块在利用常规油藏描述的基础上,应用井间地震资料和解释技术描述储层井间变化、微构造、低序级断层等都取得了明显的效果。
Modern fine reservoir description is an important technical method to increase oil recovery efficiency,it can be applied to stratigraphic division and correlation,reservoir characteristics,oil-gas-water distribution,sedimentary microfacies researches and geological reserves calculation in petroleum and so on,by using 3-D dimension seismic,drilling and coring,well logging,exploiting etc.With the raising of recovery efficiency,further descriptions of reservoir spreading and heterogeneous variations through wells and crosswell seismic technology are required.Based on utilizing routine reservoir description,applying crosswell seismic data and interpretation devices to the descriptions of reservoir variations,microstructures and low-grade faults in Fan 124 Block has acquired great effects.
