摘要:
页岩气含气量主要由吸附气量和游离气量组成,其影响因素较多,综合考虑地质关键因素进行含气量预测,有效克服了利用单一因素定量评价含气量的局限,达到更好的预测效果。将页岩含气量与各个影响地质参数指标相关性分析,优选出影响含气量的关键地质参数;通过对优选的地质关键因素分别与总含气量和吸附气量进行数学关联性分析并建立含气量模型;基于丰富的测井资料定量求取影响含气量各地质关键参数连续性剖面,利用建立的含气量模型定量评价页岩储层含气量。实现利用测井资料对页岩储层含气量进行连续性定量评价的目的,为现场试气层位的优选和区块“甜点”评价提供有效的技术支撑。
Abstract:
Shale gas content is a key parameter for determining the reserves in shale gas exploration and development. It not only relates to the amount of gas produced by a single well, but also determines the amount of shale gas reservoir resources. The content of shale gas is mainly composed of adsorbed gas and free gas and is influenced by many factors. Therefore, in the prediction of gas content, it is necessary to comprehensively consider the key geology factors, this can eliminate the effects of single factors and achieve the purpose of accurately calculating gas content. In this paper, the correlation between shale gas content and various geological parameters are analyzed, and the key geological parameters affecting gas content are selected. Then, a mathematical correlation analysis is performed with the preferred geological key parameters and the total gas content and absorbed respectively, according to analysis, the gas content model is established. Finally, based on the abundant logging data, the key geological parameters affecting gas content are obtained and a continuous profile is obtained. The gas content of the shale reservoir was quantitatively evaluated by the established model, and the purpose of using the logging data to quantitatively evaluate the gas content of the shale reservoir is realized. Which provides effective technical support for the optimization of the on-site gas test position and the evaluation of the “sweet spot”.
