摘要
定量计算非烃类气体(二氧化碳)的含量在气藏开发中至关重要。在借鉴他人的实验结果的基础上,探索研究并得到二氧化碳在地层温压条件下的测井响应值方程,进而应用地层组分分析采用最优化原理计算地层中非烃类气体的含量。实际应用表明所提出的方法在南海某盆地应用效果较好,实现了由测井资料定量计算烃类气相对含量并由此区分非烃类气与烃类气层的应用。
Abstract
Quantitative calculation of non-hydrocarbon (CO2) gas content is very significant in the development of gas reservoirs. In this paper, by using experiment data from other people, the logging response equation of carbon in formation conditions has been obtained by studying. Based on the principle of composition analysis in stratum and the principle of optimization analysis, the content of carbon dioxide in formation has been obtained. The application results indicated that this quantitative calculation method is suitable for the basin in South China Sea, the relative contents of hydrocarbon gas can be calculated quantitatively with logging data, which can be used to discriminate hydrocarbon and non-hydrocarbon gas.
