水平井测井解释中井眼轨迹与油藏关系分析技术

在以水平井为主要开发手段的油藏中,为了提高水平井段有效储层钻遇率,优化完井方案,提高注采效果,就必须对水平井井眼轨迹与所钻遇地层的接触关系进行精细的分析,实现油藏的高效开发.以塔里木某油田为例,对水平井测井资料的处理方法及水平井钻井过程中的井眼轨迹与油藏的各种接触关系与特点进行了详细的介绍,提出了一套针对水平井井眼轨迹与油藏关系的分析方法.在实际应用中,提高了测井解释的精度,拓展了测井资料的地质应用领域.

The Analysis Technique of Relationship Between Well Trajectory and Reservoir in Horizontal Log Interpretation

For efficiently developing reservoirs, it is necessary through fine analyses of the contact between well trajectory and target formation to improve drilling effective ratio, optimize completion programme and increase injection-production results in the reservoirs developed by drilling horizontal wells. Detailed are the processing methods of horizontal well logging data and an analysis method for relationship between well trajectory and target formation. The analysis technique has improved interpretation accuracy and extended the log data application in geology.
