牛庄洼陷烃源岩TOC新型测井多参数复合评价方法研究
|
摘要
本文结合牛庄洼陷地质特征,剖析了前人关于双孔隙度法、碳氧比法、自然伽马法以及ΔLogR法在该地区烃源岩TOC测井评价的适应性,认为这些方法由于与该地区的岩性特征、方法固有参数及基线选取的误差等关联,使得烃源岩TOC测井评价的精度不高甚至根本不适合.依据牛庄洼陷地区的实测TOC和测井资料,本文通过构建TOC含量与自然伽马、声波时差以及电阻率的关系,从而形成了一套适合本地区且操作方便的测井多参数改进计算模型.结果表明,改进模型TOC的计算值与实测值之间绝对误差小于0.4的点占总数的91.7%,证实该模型求取牛庄洼陷烃源岩TOC值的准确性和可靠性.改进后的模型为牛庄洼陷烃源岩TOC测井评价提供了一种新的方法,具有良好的应用前景.
Combined with the geological characteristics of Niuzhuang Sag,this paper explored the adaptability of previous methods,such as dual porosity model,C/O well-logging model,gamma-ray model and ΔLogR method,on TOC logging evaluation of hydrocarbon source rocks. However,due to different lithological features,parameters and baseline error,the methods mentioned above were not suitable for TOC logging evaluation in research area.According to TOC data and logging information of Niuzhuang Sag,the modified calculation model which is using GR,AC and resistivity data to compute TOC correctly for this area can be built.The results show that the proportion of point that absolute error between TOC calculated and tested value is less than 0. 4 is 91. 7%and confirm accuracy and reliability of the model. The modified calculation model provides a new method for source rock TOC evaluation in Niuzhuang Sag,and also has a good application prospect.
