新庄稠油低阻油层与水层的电阻率差别不大,常规测井方法很难识别,需要寻找更有效的适合低阻油层的解释方法。以岩心分析、试油、投产等资料研究为基础,建立了参数解释图版;用中子孔隙度曲线同介电常数、相位角曲线重叠识别油层;用介电测井资料结合常规测井资料综合进行稠油低阻油层解释。实际应用证明,该方法能够有效区分新庄稠油低阻油层与水层,提高了解释符合率。
The difference between the resistivity of the low resistivity reservoir and the aquifer in Xinzhuang heavy oil is not obvious. The conventional well logging methods are difficult to identify. Therefore, it is necessary to find a more effective interpretation method suitable for the low resistivity reservoir. Based on the data of core analysis, test oil and production, the parameter interpretation plate was established. The oil layer was identified by the overlap of neutron porosity curve and dielectric constant and phase angle curve. Using the combination of dielectric well logging data and conventional well logging data For heavy oil low resistivity interpretation. The practical application proves that this method can effectively distinguish the low resistivity reservoir and the water layer of Xinzhuang heavy oil, and improves the coincidence rate of interpretation.
