摘要
陆梁油田陆9区白垩系呼图壁河组、侏罗系西山窑组油藏属于低幅度构造油藏,具有油层数量多、纵向跨度大、砂泥岩薄互层、非均质性强、油水关系复杂、低电阻油、水层识别难度大等特点。为加快开发节奏,加速探明储量向商业储量转化,应用现代油藏描述技术和评价方法,通过微幅度背斜与主要含油砂体配置关系的研究和现代油藏工程方法,在借鉴国内外多含油层系油田开发经验基础上,结合技术经济评价方法,科学、合理地划分该油藏的开发层系,确定了油藏井网形式和井距,为陆梁油田的开发建设决策提供理论依据。
The Hutubi river formation(Cretaceous)and the Xishanyao formation(Jurassic)in Lu9Well Block of Luliang oilfield belong to low amplitude structural reservoirs characterized by lots of payzones,big vertical span,sand-mud laminated zones,serious heterogeneity,complicated oil vs.gas,low resistivity,difficult recognition between pay-zones and water layers,etc.This paper is for the purpose of speeding up development rhythm and changing the proved reserves into the commercial reserves,and presents the scientific and reasonable classification of development se-quences of the reservoirs,determination of the well pattern and spacing for them by means of the experiences from de-veloping multizone petroliferous sequences at home and abroad,integrated with technical economic evaluation ap-proaches,modern reservoir engineering process and modern reservoir characterization and assessment methods,in which correlation configuration between the low amplitude anticline and the main oil-bearing sand body is studied.
