吉林油田红岗地区扶余油层具有油质轻、岩屑显示级别低、地层电阻率低、气测异常显示和岩石热解地化分析值低的特点,应用常规录井技术难于实现有效识别和准确解释评价,甚至可能漏掉油层。针对此情况,在列举录井面临的问题及应对措施的基础上,探讨了采用气测冲淡系数法校正后的气测全烃和岩石热解地化烃类恢复系数法校正后的地化含油气总量进行油层识别与解释评价的方法,并针对该地区扶余油层的特点,给出了应用岩石热解地化含油气总量结合电测孔隙度的解释评价图板。应用实例分析表明,采用不同录井技术结合常规录井和电测孔隙度可实现油层的有效识别与准确解释评价。
The Fuyu oil layer in Honggang area of Jilin Oilfield has the characteristics of light oil, low cuttings display level, low formation resistivity, abnormal gas detection and pyrolytic geochemistry analysis value of the rock. It is difficult to identify and accurately explain the conventional logging technology Evaluation, may even miss the reservoir. In view of this situation, on the basis of enumerating the problems and countermeasures of well logging, this paper discusses the correction of the geochemical oil after the correction of hydrocarbon and rock pyrolysis using Hydrocarbon Recovery Coefficient Gas total amount of oil layer identification and interpretation of evaluation methods, and for the characteristics of the Fuyu oil layer in the region, given the application of pyrolytic geochemical total oil and gas combined with the measured porosity of the interpretation of the evaluation board. Application example analysis shows that different logging techniques combined with conventional logging and electrical porosity measurement can effectively identify and accurately evaluate the reservoir.
