储层定量荧光技术在渤海海域致密储层流体识别中的应用——以黄河口凹陷BZ-A构造为例
|
摘要
利用常规测井资料评价致密储层的含油气性往往具有多解性。根据储层定量荧光分析(QGF和QGF-E)的技术特点,将其应用于渤海海域黄河口凹陷BZ-A构造沙河街组储层中,结合测井解释和试油结果,探究该技术在致密储层流体识别中的应用效果。研究表明,通过QGF-E强度得出的BZ-A构造现今油水界面与测井解释的界面深度相近。研究区油水层的判别基准线约为70pc,含油饱和度与QGF-E强度正相关,测井解释为油层段的样品QGF-E强度值绝大多数>70pc,含油水层和水层段均小于该值。利用储层定量荧光技术建立了该区含油性判别标准并利用试油结论进行验证,有效识别出了沙一段上部干层段和测井资料遗漏的沙一段下部的致密油层,该技术可以为判别致密储层的流体性质提供新的方法支持。
Conventional well logging data is not sufficient and effective for identification of tight oil reservoirs correctly.In this case of the Structure BZ-A in the Huanghekou Sag,quantitative grain fluorescence technique(QGF and QGF-E)is adopted,with the support of logging and testing data,to identify fluid properties in tight reservoirs of the Shahejie Formation on Structure BZ-A of the Huanghekou Sag.Results show that the current oil-water interface in well BZ-A-2 is close to the depth of well logging.The base line of oil layers is around 70 pc in the studying area.Therefore,most of the oil zones detected by well logging data is above 70 pc and all water layers are below 70 pc.Dry layers in the upper section of the Member Sha1 and oil zones in the lower section have been detected by QGFE data,but missed in well logging data.In conclusion,the quantitative grain fluorescence technique is a new and effective mean for detecting hydrocarbon bearing layers in tight reservoir.
