[期刊论文] 作者：Ke-Ran Qian,Zhi-Liang He,Xi-Wu Liu,Ye-Quan Chen,
来源：石油科学（英文版） 年份：2018
Shale reservoirs are characterized by low porosity and strong anisotropy.Conventional geophysical methods are far from perfect when it comes to the prediction of shale sweet spot locations,and even less reliable when attempting to delineate......

来源：石油科学（英文版） 年份：2018
Fracture systems in nature are complicated.Normally vertical fractures develop in an isotropic background.However,the presence of horizontal fine layering or horizontal fractures in reservoirs makes the vertical fractures develop in a VTI (......
Construction of a novel brittleness index equation and analysis of anisotropic brittleness character
[期刊论文] 作者：Ke-Ran Qian,Tao Liu,Jun-Zhou Liu,Xi-Wu Liu,Zhi-Liang He,Da-Jian Jiang,
来源：石油科学（英文版） 年份：2020
The brittleness prediction of shale formations is of interest to researchers nowadays.Conventional methods of brittleness prediction are usually based on isotropic models while shale is anisotropic.In order to obtain a better prediction of ......
Pre-stack seismic density inversion in marine shale reservoirs in the southern Jiaoshiba area, Sichu
[期刊论文] 作者：Yuan-Yin Zhang,Zhi-Jun Jin,Ye-Quan Chen,Xi-Wu Liu,Lei Han,Wu-Jun Jin,
来源：石油科学（英文版） 年份：2018
For a typical marine shale reservoir in the Jiaoshiba area,Sichuan Basin of China,P-impedance is sensitive for identifying lithology but not suitable for indicating good shale reservoirs.In comparison,density is an important quantity,which ......
Study of the relationship between fractures and highly productive shale gas zones, Longmaxi Formatio
[期刊论文] 作者：Yu-Feng Li,Wei Sun,Xi-Wu Liu,Dian-Wei Zhang,Yan-Chun Wang,Zhi-Yuan Liu,
来源：石油科学（英文版） 年份：2018
Shale fractures are an important factor controlling shale gas enrichment and high-productivity zones in the Longmaxi Formation,Jiaoshiba area in eastern Sichuan.Drilling results have,however,shown that the shale fracture density does not ha......
