摘要
为了充分评价油藏聚合物驱效果及其影响因素,选用微量元素示踪剂进行了聚合物驱示踪监测。在现场施工、取样、制样基础上进行了井间示踪监测结果分析,包括:示踪剂产出曲线拟合情况分析,示踪剂产出曲线形态分析,水驱方向和速度分析,主流高渗通道水驱波及参数分析。在原有地质建模基础上,通过产出曲线拟合进行了模型校正,建立了较为精确的地质模型,揭示了油藏剩余油分布及水淹规律。同时,提出了改进的聚合物驱方案,实施后取得了较好的效果。
In order to evaluate the effectiveness of reservoir polymer flooding and the influence factors on the flooding effectiveness,the microelement tracer is used to monitor the process of polymer flooding. The monitoring results of wells are analyzed,including analysis on curves formed by tracer,analysis on direction and rate of water flooding,the parameter analysis of water flooding along the main high-permeability channels. A more accurate geological model is developed based on former models. The model corrected by producing curve with tracer can be used to discover the rules of remaining oil distribution and watered out in reservoir. Some suggestions for modifying the project of polymer flooding are brought forward and put into practice. The good effectiveness has been obtained.
