特低渗储层产能模糊综合评价方法研究
|
摘要
针对特低渗储层受非均质性影响,难以准确获取表征储层真实产能的渗透率、供液半径等主要参数的问题,运用模糊综合评价理论,从定性评价和定量评价2个方面选取了影响储层产能的关键因素,通过建立合理的多级综合评价指标体系,对特低渗储层产能进行科学合理的评价。实例应用表明,涠洲6-1油田和涠洲9-3油田单井综合评价结果与实测产能相对误差分别为2. 2%和3. 8%,证实评价结果可靠性较高。该方法为寻找油田后续接替储量具有一定指导意义。
The reservoir permeability,drainage radius and other typical key parameters cannot be accurately obtained due to the heterogeneity of ultra-low permeability reservoir. The fuzzy comprehensive evaluation theory was used to qualitatively and quantitatively evaluate the key influencing factors for reservoir productivity. A reasonable comprehensive multi-level evaluation index system was established to scientifically and properly evaluate the productivity of ultra-low permeability reservoir. Field application indicates that the relative errors between the individual-well productivity evaluation and tested productivity are only 2.2% and 3.8% respectively,which shows a favorable reliability of this evaluation. This research could provide certain guidance for exploring subsequent replacing reserve.
