摘要
受储气库强注强采运行模式的影响,调峰采气过程中储层易发生出砂风险,而出砂将严重影响储气库的寿命和调峰能力。常用的定性经验出砂预测方法缺乏直观、综合的结果,且单一预测指标具有很大的局限性。针对这一问题,综合考虑孔隙度法、声波时差法、组合模量法、出砂指数法和斯伦贝谢比法等定性经验出砂预测方法,采用层次分析法和模糊综合评判决策,建立定性经验出砂预测的模糊综合评判模型,对不同射孔段的地层出砂结果进行预测分析。应用实例表明,该方法实现了不同射孔段的地层出砂结果预测,提高了地层出砂预测的准确性和综合性,对储气库长期安全运行具有重要意义。
Affected by the operation mode of gas storage with strong injection and production,the risk of sand production is prone to occur in the reservoir during peak shaving and gas production.Once sand is produced,it will seriously affect the life and peak shaving capacity of the gas storage.The commonly used qualitative empirical sand prediction methods lack intuitive and comprehensive results,and a single prediction index has great limitations.In response to this problem,qualitative experience sand prediction methods such as porosity method,acoustic time difference method,combined modulus method,sand production index method and Schlumberger ratio method are considered comprehensively,and analytic hierarchy process and fuzzy comprehensive evaluation decision-making are adopted to establish qualitative experience.The fuzzy comprehensive evaluation model for sand production prediction can predict and analyze the sand production results of different perforation sections.Application examples show that this method has realized the prediction of formation sand production results in different perforation sections,improved the accuracy and comprehensiveness of formation sand production prediction,which is of great significance to the long-term safe operation of gas storage.
