摘要
针对大庆外围油田萨葡油层砂体分布零散,现井网水驱控制程度低,开发中后期剩余油分布零散等问题,在研究不同井网的剩余油分布类型及合理加密方式基础上,深入研究了以精细油藏描述成果为依据,以可调厚度为加密下限,以周围生产井采出程度和含水为参考的井位优选方法。应用这套方法指导大庆外围油田中高含水萨葡油层的加密调整,提高了井网加密效果和经济效益。
In viewpoint of the following problems in Sapu oil layers of peripheral oilfields ： scattered distribution of sand body, low control degree of water flooding under the condition of current well pattern and stray residual oil distribution in the medium and late stages of development and so on, on the basis of the studies of different pattern＇ s residual oil distribution type and reasonable infill mode, the paper deeply studies well location optimizing method on the basis of the results of fine oil reservoir characterization and taking adjustable thickness as infill limit and furthermore taking the produced degree and water cut of adjacent producers as parameters. The set of methods can guide the infill adjustment of Sapu oil layers with medium and high water cut of Daqing peripheral oilfields and increases the infill effects and economic benefits of these oilfields.
