| 摘 要： | 随钻中子测井在随钻测井中占有重要地位。本文针对目前国内外随钻测井资料的精细解释与应用所存在的质量问题,根据实测的随钻中子测井曲线变化情况,重点研究了随钻中子测井环境影响因素及其校正方法。通过对随钻中子测井环境影响校正图版的离散采样读值和最优拟合,并考虑其适用条件,以标准化公式(模型)来代替多张校正图版曲线,实现随钻中子测井资料的环境影响自动校正。实测资料的处理表明,该法结果可靠,能够明显地提高随钻地层评价和地质导向的效果。

| Abstract: | LWD neutron logging takes an important part in logging-while-drilling(LWD). In this paper the environmental factors and corrector method in LWD neutron logging are studied based on the change of the logging curves according to the problems in LWD data interpretation and application at home and abroad. It has been carried out through discrete sampling, reading and best fitting for the calibration plate, considering its applied condition and replacing many correction plate curves with a normalization equation ( model). Field data processing shows that this method is reliable and it can improve the effect of LWD formation evaluation and geosteering. |
