摘要
化学驱增油量是评价化学驱效果的一个重要指标。胜利油田化学驱增油量预测方法是在该油田已经实施化学驱各项目增油变化规律分析研究的基础上,综合考虑了油藏条件、化学驱所处阶段及化学驱方法,对已经转后续水驱项目采用递减法预测增油量;正注聚项目根据与同类型油藏已经建立的类比模型进行类比预测增油量;二元复合驱项目应采用数值模拟方法预测增油量。此预测方法能较全面、准确地进行化学驱增油量预测。
The ineremental oil by chemical-flooding process is the main appraisal index for the process effect and the scientific basis for its planning. This prediction method for incremental oil by chemical flooding process in Shengli oilfield is based on the analysis of incremental oil rules at all the chemical-flooding Hocks in this oilfieht, considering the reservoir conditions of blocks, the different development stages and methods of chemical-flooding process. For converting into water flooding projects the decline method should be used to predict the incremental oil： for polymer flooding projects the analog method should be used： for two-compound-combination flooding the numerical simulation method shouht be adopted. These prediction methods are proved to be more comprehensive and accurate for prediction of incremental oil in Shengli oil fieht.
