大斜度井测井资料处理方法

Methods for Processing Highly Deviated Well Log Data

在大斜度井测井资料处理中,用线性插值法把钻井点测的井斜数据转换成连续测井曲线,对大斜度井进行斜深校正,得到实际垂直深度(TVD)测井曲线;用最小曲率半径法计算井眼轨迹数据(如ZD、XE、YN、HOFF、HOAZ),绘制出大斜度井的井眼轨迹图。用这些方法编制的测井资料处理软件,绘出的图表和图形直观、清晰,精确度高,能完全满足油田地质分析家的需要。

The drilling stationary measurement hole deviation data are converted to continuous log curves by using the linear interpolation method in processing of highly deviated well log data, and the log data are corrected for deviated depth to get true vertical depth log curves. The minimum curvature radius method is used to compute hole trajectory data (such as ZD,XE,YN,HOFF,HOAZ, etc. ) to draw the highly deviated well hole trajectory graph. The diagram and graph, drawn with the log data processing software that programmed using these methods, are visual, clear and highly accurate, completely meeting the need of oilfield geology analysts.
