摘要
针对辽河葵东地区低电阻率油层发育,产能预测难的问题,基于平面径向稳态渗流原理,分析油层产能的主控因素,建立区域比采油指数预测模型,利用岩心、测井资料构建相关储层参数测井解释模型,初步实现了辽河葵东地区低电阻率油层产能预测。研究表明:葵东地区油层产能的主控因素是储层构造特性、岩性和物性;油层比采油指数与地层渗透率具有较好的相关性;采用阵列感应反演的地层原状电阻率计算地层含水饱和度,计算结果更合理;要实现辽河葵东地区低电阻率油层的产能预测,应优选核磁共振和高分辨率阵列感应测井。该研究对同类储层产能预测具有借鉴意义。
The principle of lateral radial steady flow was used to improve the productivity forecast for the well-developed low-resistivity reservoirs in Kuidong of Liaohe.The main-controlling factors of productivity were analyzed to establish a regional specific oil production index prediction model.The core test and logging data were used to establish the logging interpretation models of relevant reservoir properties.The productivity forecast was preliminarily achieved for the low-resistivity reservoirs in Kuidong of Liaohe.Result indicates that the main-controlling factors for the low-resistivity reservoirs in Kuidong includes reservoir structure properties,lithology and physical properties.There is a favorable correlation between the specific oil production index and the reservoir permeability.The original formation resistivity of array induction logging inversion was used to calculate the reasonable formation water saturation.NMR and high-resolution array induction logging are recommended to forecast the low-resistivity reservoir productivity in Kuidong.This research could provide certain reference for the production forecast of similar reservoirs.
