摘要
传统导向方法利用邻井、地震资料建立的地层模型难以反映目标层段的真实地质构造与测井信息,无法实时和直观地确定井眼与地层相对位置关系,水平井实际作业带有很大的不确定性及风险。基于随钻测井响应反演的地质导向建模技术,通过建立数据传输构架,实时获取随钻测井响应数据,同时通过引入地质约束条件、钻前测井响应模拟及实时地层界面反演构建出导向模型,实现了地层参数、井眼轨迹与目的层位置关系的随钻分析。渤海油田实际应用效果表明,构建的导向模型可信度较高,可为水平井的导向决策提供较为可靠的依据。
The formation model established by traditional steering method using adjacent wells and seismic data is difficult to reflect the real geological structure and logging information of the target interval,and cannot determine the relative position relationship between the borehole and the formation in real time and objectively.Meanwhile,the actual operation of horizontal wells has great uncertainty and risk.Based on the geo-steering modeling technology of LWD response inversion,the LWD response data is obtained in real time by establishing a data transmission framework.At the same time,the geo-steering model is constructed by introducing geological constraints,pre-drilling logging response simulation and real-time stratigraphic interface inversion,which realizes the analysis while drilling of the relationship between formation parameters,wellbore trajectory and the location of the target layer.The practical application results show that the guidance model has a high reliability,which can provide a good reference for the decision-making of horizontal wells.
