摘要
通过精细构造解释、多井约束储层反演、三维精细地质建模等技术手段,分析敖南油田具有砂层多、厚度薄、隔层厚度大、地层倾角大且横向连续性差的特点.通过技术经济对比,确定采用水平井开发是可行的,继而给出该油田薄差储层水平井优化设计方案,即采用单层水平井,水平井段沿东西向布置,构造上从高部位向低部位钻进,设计水平段长度为500～600m,确定水平井加后期直井加密为最优方案.
In this paper we analyzed the characteristics of Aonab oil field,such as multi sand layer,thin thickness,big thickness of the interlayer and the large formation strata dip,poor lateral continuity through sophisticated technical means of fine structural interpretation,multi-well constrained and inverse layer,three dimensional fine geological modeling.Moreover,horizontal wells are feasible for oil field development by technical and economic comparison.Then optimal design of horizontal wells is offered for the thin and poor layer in the oilfield.They are horizontal wells for single layer,horizontal along the east-west layout,drilling from high to low in geological structure,horizontal length from 500 m to 600 m,optimal program of horizontal and vertical wells later.Implementation of the design in the oilfield has achieved better results.
