摘要:
总有机碳质量分数(TOC)是评价泥页岩生烃能力的关键指标之一,也是评价泥页岩油气甜点的重要参数。针对松南地区SJT地区陆相泥页岩储层,提出了一种TOC定量预测新方法。该方法通过修改模型系数,引入新的测井参数,联合铀预测技术和Δlog R法拟合TOC;同时,在分析泥页岩地球物理响应特征规律的基础上,结合正演分析建立泥页岩储层段的典型波形结构特征与TOC的相关性,利用波形指示反演技术在贝叶斯框架约束下预测TOC分布。利用该结果部署的Y1井钻遇富有机质泥页岩,在Y1井以南部署的水平井连续钻遇气测显示层,验证了新方法的可靠性,对陆相泥页岩TOC的区域评价提供了一种新的解决方案。
Abstract:
The total organic carbon content(TOC) is one of the key indicators to evaluate the hydrocarbon generation capacity of mud shale and also the major parameter for evaluating the oil-gas sweet spot of the mud shale. A new method to predict TOC quantitatively is proposed for mud shale reservoir in Songnan SJT area. By modifying model coefficient and introducing new logging parameter, this method combined radioactive uranium log and Δlog R technology to fit TOC. At the same time, based on analyzing the geophysical response characteristics of mud shale,combined with forward modeling,the correlation between typical waveform structure characteristics and TOC of mud shale reservoir section was established and the waveform indication inversion method was chosen to predict TOC distribution under the constraint of Bayesian framework. Using the prediction results, well Y1 was drilled with organic-rich mud shale and the horizontal well drilled to the south of Y1 well was also encountered continuous gas show,which verified the reliability of the method and provided a new solution for the regional evaluation of TOC of continental mud shale.
