陆相沉积盆地泥页岩含气量影响因素探讨——以潍北凹陷为例
|
摘要
页岩气以游离态和吸附态赋存于泥页岩中,泥页岩含气量的多少是页岩气资源潜力评价的重要指标,也是勘查开发过程中最重要的制约因素。该文利用潍北凹陷大量实测数据,分别建立泥页岩含气量与有机地化参数、储集物性参数、矿物成分等相关关系图,探讨各参数与泥页岩含气量的相关性和影响因素。研究表明:含气量与有机碳含量相关性最好,相关强度达到中等正相关;孔隙度与含气量无相关关系;岩石密度与含气量、有机碳含量均具有中等程度的负相关。提出了间接获取泥页岩含气量的方法和手段,为准确地评价页岩气资源潜力提供依据。
Shale gas occurred in shale with the form of free and adsorb. Gas content is not only an important index for shale gas resource potential evaluation,but also a restriction factor in the process of shale gas exploration and development. In this paper,correlation diagram of shale gas content and organic geochemical parameters,reservoir physical parameters,mineral composition has been set up by using a large number of measured data of Weibei sag.According to the above curves or number,the relationship and influencing factors between various parameters and shale gas content have been discussed. It is showed that the correlation between gas content and organic carbon content is the best,and the correlation intensity is moderately positive. Porosity and gas content are not related; rock density is negatively correlated with gas content and organic carbon content. Indirect ways and means for acquiring the gas content of the shale has been put forward. It will provide the basis for correctly evaluating shale gas resource potential.
