摘要
隔夹层是油藏开发研究的重要内容之一。目前隔夹层研究多侧重于单井的岩心、测井识别和井间的随机模拟,很少采用地球物理方法预测井间的隔夹层分布。立足于渤海L油田实际条件,从隔夹层的地球物理特征分析入手,开展隔夹层弹性参数识别研究,优化地震道集资料,采用叠前直接反演研究成果开展井间隔夹层分布规律预测,完成了该油田明化镇组下段三套隔夹层(组)的平面分布预测,为渤海L油田地质模型建立、开发井网优化给出了可靠的研究成果。基于隔夹层地球物理特征的分析方法,能够实现隔夹层井间分布规律研究,提高预测结果的可靠性,为类似油藏的隔夹层研究提供了良好借鉴。
The research on the intercalation is one of the important contents in oil reservoir development. At present,this study more focuses on the identifications of the core,logging fo the single well and moreover the stochastic simulation beyond the scope of the wells,the geophysical methods are less adopted to predict the interwell intercalation distribution. on the bases of the actual conditions of Bohai L Oilfield,started with the analyses of the geophysical characteristics of the intercalations,the identifying studies were caught out on the intercalation elastic parameters,the seismic gathers were optimized,the research achievements of the prestack direct inversion were used to predicted the spatial distribution of the inter-well intercalations,the predictions of the spatial distribution were completed for three sets of Minghuazhen Formation intercalations of the oilfield,thus the reliable achievements were presented for the geological modeling and development well pattern optimizing of Bohai L Oilfield. Based on the analyzing method of the geophysical characteristics of the intercalations,the law researches on the interwell distributions of the intercalations have realized,the reliability of the predicted results has been enhanced,and furthermore much better reference has provided for the studies on the intercalations of the similar oil reservoirs.
