摘　　要：B油田是海上常规稠油油田,开发至今油井出砂严重,导致部分油井关停。近几年主要采用化学防砂工艺治理,利用FSG药剂胶固地层砂,达到控砂的目的。从油藏角度进行研究,对已治理井生产数据跟踪分析,引用皮尔逊相关系数算法研究化学防砂效果与油藏涉及参数的相关性,识别出泥质含量和米采液指数与化学防砂效果相关性较强,其次是日产液和采液指数参数。应用上述成果辅助C平台化学防砂工艺选井,实施后增产控砂效果显著,对后期油藏化学防砂措施选井有一定的指导意义。B oilfield is an offshore conventional heavy oil field.Sand production has been serious so far,leading to the shutdown of some oil wells.Chemical sand control technology was mainly used in recent years.FSG was used to cement formation sand and achieve the purpose of sand control.This paper studied from the reservoir parameters,analyzed the production data by using Pearson correlation coefficient algorithm to find out the correlation between the sand control effect and reservoir parameters,and identified that the shale content and meter production fluid index had strong correlation with sand control effect,followed by daily production fluid and production fluid index.Applying the results to assist the well selection of chemical sand control technology of platform C was remarkable,which has certain guiding significance for the chemical sand control well selection of reservoir in the later period.
