测井资料评价烃源岩方法及其进展

Methods for Evaluating Source Rocks by Well-logging Data and Its Progress

在经典烃源岩地球化学评价中,一般都是对所取烃源岩样品进行分析测试,通过得到的各种实验数据判断烃源岩性质,有效的指导了油气勘探与评价。但是烃源岩具有的宏观和微观非均质性使得分析样品一般只具有特殊性,解决该问题的理想方法是连续的取心及无间隔的样品分析,这从实际操作和研究经费上来说都是不现实的。随着测井技术提高,利用测井资料分析烃源岩成为可能,并能克服取样有限的缺点,使得烃源岩在纵向上能够得到连续性的分析,因此利用测井资料的解释成果并结合经典地球化学分析测试数据,能够更有效的预测和评价烃源岩的性质。

Classic geochemical evaluation on hydrocarbon source rocks,the hydrocarbon source rock characteristics were judged through analysis of samples of various experimental data,it was effective to guide petroleum exploration and evaluation.But for the hydrocarbon source rocks,analysis of samples generally had a speciality made by macroscopic and microcosmic heterogeneities,an ideal method to solve this problem was to have a continuous coring and continuous analysis of samples.From the actual operation,this research method is not real.With the logging technology improvement,the shortcomings are overcome and hydrocarbon source rocks are analyzed by well logging data.So the results by well logging data interpretation of classic geochemical analysis on test data can be more effective to predict and evaluate the hydrocarbon source rocks properties.
