经济评价模型在防砂方法优选中的应用

Application of Economic Evaluation Model to Optimization of Sand Control Method

根据油田防砂的基本情况,考虑到油田产能、有效期及作业成本等因素,建立了优化防砂方法的经济评价模型。利用净收益、产出投入比等指标对若干种技术评价指标较高的防砂技术进行了经济对比分析,该模型为最终选出技术上合理、经济上可行的最佳防砂方法提供决策支持。实例评价结果表明,该经济评价模型具有简洁、科学、针对性强等特点,比较适用于对防砂方法的优选。

According to the basic situation of sand control in oil field,the economic evaluation model for optimizing sand control method is developed on the basis of oilfield productivity,validity and operation cost. Some sand control technologies with high evaluation index are economically analyzed by using net income and yield ratio. The model can be used to select the optimum sand control method that is reasonable in technology and usable in economy. The evaluation result indicates that the economic evaluation model is simple and fits for optimization of sand-control method.
