克拉玛依砾岩油藏高含水区块井网加密潜力

The Potentials of Well Pattern Infill Development of High Water-Cut Blocks in Karamay Conglomerate Reservoirs

针对克拉玛依油田砾岩油藏井网开发中剩余油分布零散、关闭井比例大、注采不完善的现状,应用油藏工程方法、油藏数值模拟技术及经济评价方法,研究形成了包括井网加密界限、合理加密方式、加密井井位及加密产能等在内的井网加密潜力确定方法,为克拉玛依油田砾岩油藏及类似油藏井网加密调整潜力研究提供了实用方法。

In view of the unsatisfied status of Karamay conglomerate reservoir development such as dispersed distribution of remained oil,larger scale of closed-in wells and injection-production imperfection,this paper presents the practicable method for determination of well pattern infilling potentials including infilling limit,rational infilling mode,infilling well location and productivity,etc.which could be as a guide for other similar reservoirs development.
